LAS VEGAS — General Motors used the 2007 SEMA Show to reveal the details about the upcoming 2008 Chevrolet Cobalt SS, which promises to have more kick than the previous Cobalt SS Supercharged.

GM says the '08 Cobalt SS will churn out 55 more horses than the Cobalt SS Supercharged. The new model uses the 2.0-liter Ecotec turbocharged and intercooled engine with 260 horses linked to a GM Powertrain Sweden five-speed transmission with a short-throw shifter. It sprints from zero to 60 mph in about 5.7 seconds, according to Chevrolet. The coupe was developed by GM Performance Division, which put it through its paces at the Nürburgring circuit.

Chevy noted that the Cobalt SS coupe has powertrain and chassis enhancements that are similar to the new Chevrolet HHR SS, "but with larger Brembo brakes, a slightly taller final-drive ratio and other variances." The Cobalt SS coupe gets a new FE5 Sport suspension with specific stabilizer bars, spring rates and damper tuning. A "no-lift shift" feature on manual-transmission models is said to "achieve the best acceleration time via an algorithm in the engine controller."

Exterior features include an airdam-style front fascia with integrated projector-beam foglamps, plus a standard deck lid spoiler or optional high wing-style aero enhancement. Five-spoke 18-inch polished forged aluminum wheels and performance tires are standard.

The cabin is fitted with SS-embroidered sport seats, a specific gauge cluster, an A-pillar-mounted turbo boost gauge and a new shifter arrangement.

What this means to you: The most powerful Cobalt yet.

Will it come in Auto? i want a car for every day driving and traveling and where i live i would hate to change gears 9,000 times.

I just noticed this for all the 4 door types

Chevrolet Cobalt's 2008 SS coupe goes on sale in the second quarter of 2008. A sedan version will follow shortly afterward.

hm i want to see it

i think i was reading somewheres that the hhr SS will have a auto tranny also so im not sure if the cobalt will get it or not.

brembo swaping i see it now

I now laugh at all of the naysayers, doubter, and pessimists who said it would never come out and how stupid we were for believing it would.

All I got to say is.

I TOLD YOU SO!!!!

:lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol: :lol:

I'll need to get the brembo's asap.

From Autoblog:
After biting our tongues for the last few days while (accurate) speculation surrounding the successor to the Chevy Cobalt SS Supercharged bounced around the web, we're finally able to come clean. This is the turbocharged 2008 Chevy Cobalt SS, and it's being introduced to the world at SEMA this week. Chevy went to great lengths to ensure that the SS badge means more than what it had become in recent years.

Coming in at 260 HP / 260 lb-ft, the SS/TC gains a full 55 horses over the now-defunct SS/SC. Power, of course, is sourced from the same 2.0L direct-injected, turbocharged, intercooled sledgehammer found under the bonnets of the Pontiac Solstice GXP, Saturn Sky Red Line, and forthcoming Chevy HHR SS. The GM Performance Division was tasked with making sure the improved Cobalt SS is well-sorted, and John Heinricy and company dialed in the FE5 sport suspension on the undulating twists and turns of the Nürburgring Nordschleife. The result, says GM, is a track-capable suspension that's still comfortable on the street, and which helps mitigate FWD performance foibles like torque steer.

Follow the jump for more, plus all the official GM press materials.

The standard transmission is the GM Powertrain Sweden F35 short-throw 5-speed manual with a "no-lift shift" feature. This, combined with the punchy turbo four, helps propel the Cobalt SS Turbocharged from 0 to 60 in a scant 5.7 seconds. In fact, GM set a Nürburgring class record for FWD sport compacts with the turbo Cobalt, lapping the Green Hell in 8:22.85. Better braking accompanies the added power with 4-piston fixed-caliper Brembos in front and vented discs with single-piston calipers in the rear. A driver-selectable competition mode with launch control can be enabled from the cockpit. Beyond that, the traction control system can be completely disabled.

Appearance-wise, the Cobalt SS Turbocharged sports a unique front fascia, model-specific rocker panels, forged 18" alloys, a polished exhaust outlet, and a choice of rear wings (low or high). Inside, a boost gauge peeks at the driver from the A-pillar while SS-exclusive sport seats and interior trim dress up the cabin. The Chevy Cobalt SS Turbocharged goes on sale in Q2 of 2008, and if the coupe doesn't strike your fancy, no worries: a sedan version will follow a couple of months later. Honda, Mazda and all the rest are now on notice. There's a new player at the table, and that SS medallion he's rocking is no longer costume jewelery.

The turbo blows pressurized air into the combustion chambers to enhance horsepower and torque, while the system's intercooler circuit cools the turbocharged air charge to maximize its effect. The turbocharger is sized to deliver a significant horsepower boost and almost no spool-up lag. Maximum pressure is almost 20 psi.

wonder how the SS/SC will fair?? Im sure an S2 is comparable to a stock SS/TC

wonder how the SS/SC will fair?? Im sure an S2 is comparable to a stock SS/TC

Close in HP, but nowhere near the torque of the LNF. Not to mention the LNF hits peak torque much sooner than the LSJ, and the LNF holds max torque (perfectly flat) to about 6000rpms where it dips down a bit.

The standard transmission is the GM Powertrain Sweden F35 short-throw 5-speed manual with a "no-lift shift" feature.

Hinting that there is an optional transmission available. Even so, the F35 has a taller gear ratio, allowing first gear to run just a tad longer.

Did anyone else read that the new SS can hit .9 lateral G's!!! Thats the same as the STI, 350Z, G35, BMW Z4, SRT 6, and RX8!!!

Hinting that there is an optional transmission available. Even so, the F35 has a taller gear ratio, allowing first gear to run just a tad longer.

A crappy 4spd auto most likely. If gm won't give us a 6spd manual. There's no way were getting anymore more then a 4spd auto.

TURBOCHARGED CHEVROLET COBALT SS GIVES A BOOST OF FUN TO THE COMPACT SEGMENT

LAS VEGAS – Celebrating the performance community that comprises SEMA, Chevrolet used the annual convention of all things high-performance to announce the 2008 Cobalt SS coupe. True to its legendary moniker, the Cobalt SS delivers a balance of track-proven performance capability, driving refinement and premium features – along with an undeniably fun and youthful character.

Developed by GM Performance Division (GMPD) and powered by a 260-horsepower (194 kW) turbocharged and intercooled 2.0L Ecotec engine, the Cobalt SS delivers 55 horses (41 kW) more than the previous Cobalt SS Supercharged, and its driving experience was validated on racetracks throughout North America and Europe, including Germany's legendary Nürburgring circuit.

"The Cobalt SS is the very essence of Chevrolet's fun spirit and serious performance," said Ed Peper, Chevrolet general manager. "The horsepower will put a permanent smile on your face and you'll find yourself wanting to turn around and zip through your favorite stretch of twisty roads again."

The Cobalt SS coupe arrives in dealerships in the second quarter of 2008. A Cobalt SS sedan, with all of the same high-performance features of the coupe, follows a couple of months later.

Maximum performance – on the street or track

The Cobalt SS was developed by GM Performance Division (GMPD), with a team of engineers and designers dedicated to crafting high-performance vehicles. It features powertrain and chassis enhancements that are similar to the new HHR SS, but with larger Brembo brakes, a slightly "taller" final-drive ratio and other variances that emphasize the Cobalt SS's pure performance ethic, as well as maximize its competitiveness on the track.

Engineered to offer more than merely a turbocharged rush of power, an all-new FE5 Sport suspension was developed and includes specific stabilizer bars, spring rates and damper tuning – all designed to complement the high-output turbocharged powertrain and mitigate afflictions such as torque steer. Driver-selectable modes help maximize performance whether on the street or track. The unique "no-lift shift" feature enables manual-transmission-equipped models to achieve the best acceleration time via an algorithm in the engine controller.

Ensuring the car stops as confidently as it accelerates and corners are four-wheel disc brakes with standard ABS. The front brakes are from Brembo and have a performance-oriented fixed-caliper design, which resist fade better than floating caliper designs; the rear discs are vented for better heat dissipation. Along with these high-performance attributes, the Cobalt SS comes standard with a host of safety features, including the StabiliTrak electronic stability control system and side-impact air bags.

With its balanced tuning, the Cobalt SS delivers a quick 0-60 time of approximately 5.7 seconds – thanks to the manual transmission's "no-lift shift" feature – and a sports car-like maximum lateral grip of 0.9 g. This combination enabled the Cobalt SS to set a new class record while circulating the famed Nürburgring racing circuit, posting a time of 8:22.85 minutes.

Unmistakable style

The Cobalt SS is distinguished on the exterior with several unique features, including a distinctive, air dam-style front fascia with integrated projector-beam fog lamps. The new fascia's grille and the Cobalt's upper grille sport a new, SS-specific diamond-mesh appearance.

SS-specific rockers and badging adorn the body sides, while a standard deck lid spoiler adds the requisite sporty touch to the rear of the car. The standard spoiler can be replaced with an optional high wing-style aero enhancement that gives the Cobalt SS the look of a racecar. Also at the rear is a prominent, bright-tip exhaust outlet.

Large, five-spoke 18-inch polished forged aluminum wheels and performance tires are standard and are tailored with the specific body enhancements to give the Cobalt SS a lower, performance-oriented stance – while also showing off the large Brembo front brake calipers. They're mounted on 225/40-series summer tires. Likewise, the available exterior colors enhance the sporty nature of the vehicle. They include Victory Red, Black, Ultra Silver Metallic, Imperial Blue, Rally Yellow, Sport Red Tintcoat and White.

Like the exterior, the interior is unique to the Cobalt SS, including SS-embroidered sport seats with suede-like UltraLux inserts, a specific gauge cluster, an A-pillar-mounted turbo boost gauge and a new shifter arrangement. Three interior color combinations are available: Ebony, Light Grey and Victory Red.

GERMANY'S NÜRBURGRING RACETRACK WAS THE PROVING GROUND FOR THE '08 COBALT SS

DETROIT – The Cobalt SS is at home on the boulevard or starting grid, thanks to development at Germany's famed Nürburgring racing circuit – a winding, undulated road course of approximately 14 miles in length (22 km) and with more than 170 turns. It is considered by many professional racers and auto manufacturers as the ultimate test of a car's mettle.

In fact, the Cobalt SS set a lap record for front-drive sport-compact cars at the "'Ring," posting a time of 8:22.85 minutes – besting the previous record by more than 13 seconds.

"The Cobalt SS delivers an integrated driving experience that balances a strong, satisfying feeling of acceleration with a precise, responsive chassis," said John Heinricy, GM Performance Division executive. "It has been tuned to deliver confident handling and road manners, while also maintaining overall ride comfort."

GM Performance Division (GMPD) is responsible for the "go, stop and turn" capability of Chevrolet's high-performance SS models, and its team of enthusiastic engineers made sure that the new, 2008 Cobalt SS not only achieved stellar performance on the track, it delivered it with a grin-inducing level of driving satisfaction.

Specific performance features include:

* FE5 sport suspension
* Standard F35 five-speed manual transmission with short-throw shifter
* Quicker-ratio steering
* Brembo fixed-caliper front disc brakes
* Vented rear disc brakes
* Eighteen-inch wheels and performance tires
* Driver Information Center "Competition" mode with launch control function
* Available limited-slip differential

Chassis tuning

Conveying the Cobalt SS's turbocharged horsepower to the pavement is an FE5 sport suspension that includes a host of other chassis, steering and braking revisions – and a set of gorgeous, 18-inch forged aluminum wheels. The elements pull together to give the vehicle surprisingly agile ride and handling characteristics, as well as an enviable maximum lateral acceleration rate of 0.9 g – making it one of the best-handling cars in the segment.

"There was a concerted effort to tune the Cobalt SS for competitive track performance," said Heinricy. "This makes the car not only formidable in sanctioned competition, but it puts a finer edge on street performance."

The MacPherson strut independent front suspension uses SS-specific gas-charged twin-tube struts; unique steering knuckles with optimized geometry; 27 N/mm linear coil springs with specific damper tuning; stiffer control arm handling and stabilizer bar bushings; and a direct-acting, 24-mm solid stabilizer bar. At the rear, the SS's semi-trailing twist beam axle uses monotube gas-charged shocks with specific damper tuning, a 24-mm solid stabilizer bar, stiffer axle bushings and multi-rate coil springs (28-40 N/mm). StabiliTrak electronic stability control and traction control are standard.

More than cornering capability, the Cobalt SS's chassis – along with the available limited-slip differential – also is tuned to mitigate conditions often associated with high-performance front-wheel-drive vehicles, such as torque steer and axle hop. The result is smooth application of the car's full performance potential, quickening acceleration and/or lap times and ensuring a smooth, comfortable driving experience on the way to the office.

Quicker steering

An improved electric power steering (EPS) system is tuned to match the SS's handling prowess. The rack-and-pinion gear has a quick 14.8:1 ratio, which is 20-percent quicker than other Cobalt models, and the new EPS provides improved precision and a more viscous feel.

Brembo fixed-caliper brakes

Four-wheel disc brakes with ABS are standard. They consist of large, 12.4-inch-diameter (315 mm) Brembo front vented rotors with premium, high-performance, four-piston fixed calipers in the front and 11.5-inch-diameter (292 mm) rear vented discs with single-piston calipers.

During spirited drives, this gives the Cobalt SS a more precise and consistent braking feel that resists fading, even after repeated occurrences of hard braking, such as the driving experience on a racetrack.

The Brembo calipers are visible behind one of the Cobalt SS's most distinguishing features: a set of 18- x 7.5-inch polished forged aluminum wheels. The wheels ride on SS-specific 225/40-series Y-rated summer tires.

The standard anti-lock brakes are connected to the StabiliTrak electronic stability control system to enhance stopping and handling in emergency driving situations.

TURBOCHARGER FORCE-FEEDS THE COBALT SS 2.0L ECOTEC ENGINE FOR 260 HP (194 kW)

DETROIT – The Cobalt SS is powered by a turbocharged and intercooled 2.0L Ecotec DI engine that delivers 260 horsepower (194 kW) and 260 lb.-ft. of torque (353 Nm) with the standard five-speed manual transmission.

"Chevrolets are about fun and the SS models are the most fun of all," said John Heinricy, GM Performance Division executive. "With the Cobalt SS, fun is balanced with a serious degree of capability, on both the street and racetrack."

Features such as "no-lift shift" and other driver-selectable performance modes help the Cobalt SS achieve 0-60 mph performance in approximately 5.7 seconds and cover the quarter-mile in approximately 14.1 seconds, with minimal torque steer. The top speed is more than 160 mph.

2.0L Ecotec DI turbo engine details

The Cobalt SS's Ecotec 2.0L turbo engine is the same that powers the recently introduced HHR SS. It produces 2.1 horsepower per cubic inch of displacement (130 hp / 97 kW per liter) and is the most powerful engine in the Ecotec family. Gasoline direct-injection technology helps the engine produce more power while maintaining the lower fuel consumption of a small displacement port-injected engine.

With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower, especially at normal cruising speeds, of a conventional port-injection combustion system. Direct-injection technology works well with turbocharging and helps deliver a great balance of power and economy.

Highlights of the Cobalt SS's Ecotec 2.0L DI turbo engine include:

* Steel crankshaft
* Forged connecting rods
* Oil-spray piston cooling
* 9.2:1 compression ratio
* Aluminum cylinder head with stainless steel intake valves and sodium-filled exhaust valves
* High-pressure engine-driven fuel pump
* Mobil 1 synthetic oil

Components including the steel crankshaft and forged connecting rods are high-strength items that provide strength and enhance durability. Oil-spray piston cooling helps reduce cylinder temperatures and promotes longevity by delivering pressurized oil that continuously lubricates the pistons, which reduces friction. To enhance combustion, the piston tops feature a dish shape that deflects incoming fuel toward the spark plugs.

To accommodate the direct-injection system, the Ecotec 2.0L DI turbo has a unique cylinder head and intake manifold. The cylinder head incorporates mounting locations for the fuel injectors – items that are typically mounted in the intake manifold on port-injection engines. Specialized and extremely precise multi-hole fuel injectors are used to meter fuel and deliver it in a finely atomized manner. They are supported by an engine-mounted high-pressure fuel pump.

Apart from the mounting positions of the fuel injectors, the cylinder head has conventional port and combustion chamber designs. Large stainless steel intake valves and sodium-filled exhaust valves are durable components designed to stand up to the high-performance capability of the engine.

The unique cylinder head, fuel system, pistons and intake manifold are the major components that differentiate the 2.0L DI turbo from other members of the Ecotec engine family. Mobil 1 synthetic engine oil is installed at the factory. Synthetic oil was selected for its friction-reducing capabilities and high-temperature performance.

Turbocharger and charge air cooler

Pumping up the Cobalt SS's 2.0L Ecotec engine is an intercooled turbocharger system. The turbo blows pressurized air into the combustion chambers to enhance horsepower and torque, while the system's intercooler circuit cools the turbocharged air charge to maximize its effect. The turbocharger is sized to deliver a significant horsepower boost and almost no spool-up lag. Maximum pressure is almost 20 psi.

Because the pressurized air pushed by a turbocharger becomes heated, the Cobalt SS's system employs an air-to-air intercooling system. With it, the pressurized air passes through a heat exchanger mounted behind the grille in the lower front fascia, where it is cooled before it enters the engine. Cooler air is denser, enabling the combustion chambers to draw in more air for maximum power. The cooler air also staves off the possibility of detonation at higher temperature, which allowed engineers to tune the engine for maximum power and ensure consistent performance in all driving conditions.

Transmission

Backing the turbocharged engine is a standard GM Powertrain Sweden F35 five-speed manual transmission. Semi-synthetic transmission fluid is used for its capability of absorbing heat and resisting breakdown during high-performance driving.

A performance-oriented feature referred to as "no-lift shift" allows maximum performance – upshifts can be performed very quickly without lifting the throttle. An algorithm in the engine's controller enables this high-performance feature, which helps maximize acceleration and gear changes.

A short-throw shifter with stiffened shifter bushings and modified cables and attachments enhances confidence behind the wheel, giving the driver a firmer, more direct and quicker shift feel. A limited-slip differential is available with the manual transmission.

3.82:1 final drive ratio

The Cobalt SS's powertrain has a 3.82:1 final drive ratio, which was selected because it allows the turbocharged engine to remain in the optimal section of the torque band during shifts and while driving competitively on a racetrack. This enhances both the car's tangible performance measures and intangible fun-to-drive quotient.

PERFORMANCE-ORIENTED COCKPIT HIGHLIGHTS THE '08 COBALT SS INTERIOR

DETROIT – Every driver's element – from the highly bolstered seats to the A-pillar-mounted boost gauge – is designed to match the performance capability delivered by the 2008 Cobalt SS's 260-horsepower (194 kW) turbocharged engine and FE5 sport suspension deliver. In short, the cabin delivers maximum functionality and driver satisfaction.

The features that comprise the Cobalt SS's driver-focused interior include:

Sport seats: The Cobalt SS's seats don't just look sporty; modified seatback bolsters and "winged" bottom-cushion bolsters provide excellent support during spirited driving. The seat features contemporary, mesh-style impression cloth coverings with suede-like UltraLux inserts in the center section for additional grip. "SS" logos are embroidered on the front seats.

Contrasting interior colors, including Ebony, Victory Red and Light Grey, contribute to the sporty look and are offered in SS-only combinations. Color-matched door panel inserts complete the theme. The rear seat is trimmed to match the front seats and features enhanced bolster styling to also match the front seats.

Shifter: Compared with other Cobalt models equipped with a manual transmission, the SS features a shifter that has shorter throws between gears and a more precise feel.

No-lift shift: An algorithm in the engine's controller allows upshifts to be performed very quickly without lifting the throttle.

Steering: The Cobalt SS has a quicker-acting, more precise steering system consisting of a modified steering knuckle and a new steering gear (14.8:1 ratio).

160-mph speedometer: A unique instrument panel gauge cluster is standard; it includes a 160-mph readout (255 km/h) illustrated with large, easy-to-view graphics.

A-pillar gauge: In what is now a signature feature of models with the turbocharged 2.0L Ecotec, the Cobalt SS comes with a standard A-pillar-mounted turbo boost gauge.

Driver Information Center: The standard Driver Information Center located in the gauge cluster allows the driver to engage several SS-specific features, including a "competition" mode that is designed for closed-course performance driving and adjusts chassis controls (including turning off traction control) in controlled driving conditions. A launch control function is part of the competition mode and enables consistent acceleration performance.

Additional changes: SS-specific satin nickel trim accents the cabin, enhancing the distinctive and performance-oriented theme of the SS's driver environment.

I see they will be offering it in white too. Nice! Looks like the Cobalt is about to evolve to a new level after reading all the articles about it. Good deal!

Does anyone know if they fixed the axles? That will be a major deciding factor in this car. If the ss/sc’s can’t handle the power they have ppl will be braking axles in the new tc’s without even trying it.

I wish the pricing was out so I could decide whether to get an 07 s/c or just wait for the 08 t/c... I'd have to factor in my desire for stage 2 as well. This means there should be some great deals on the 07 ss s/c though :)

from the looks of it, it looks like only 3 "insert" colors are avalible "Ebony, Light Grey and Victory Red." if thats the case...im getting a black/red cobalt tc lol..or ofcourse...white :D

Way to CHEAP out GM. They're going to use the same POS tranny with it's 1st gear towing ratio. Not interested at all. SRT4 gets a 6spd. GM cheats out and uses the same old 5spd from the previous model.

They did reduce the final drive though to 3.82 . I think this trans will work well with the LNF .

The axles for 2008 are new .

Where are u seeing this? and also White FTL

I want to see pics damn it!

I want to see pics damn it!

x2 on that. but its says it has ss seats but its called the sport model now. so whats up with that ?

I would like to see some more info on pricing and pics of what the car will really look like inside and out.

The new turbo one will remain the SS.

so they named the 2.4 sport to get away from 1 more ss badge in the bunch. wow

wow, did cobaltss.net call this one or what?! :bow:
Mad props to all of the member who helped uncove it on 10/22/07, 6 days before it was announced!
To all of those that called BS and sent me hate mail..........I told you so :p

ok question... 14.1 seconds for the quarter mile isnt that a little bit slow?????? i thought that a stage 2 could hit a 13.xx time... and the LNF should have amazing 60' times compared to the LSJ since wheel hop will be solved by turbo spooling is there something im missing here?

1/4 times can always vary. I think I saw a review for the ss/sc back in 05 running a 15.1. that seemed wrong and it pretty much was. 14.1 could be an average. im sure 13s are possible with a skilled driver. who knows. I would definetly want to test drive one. Launch control seems interesting.

the same people drove our car, and got a 14.5-14.8 now they drove it and got a 14.1 can you imagine what that means for us?? Well def. hit 13's since we knocked it down to 14.1 stock .4-.5 less than what we was supposed to run, we should be in the mid 13's stock

haha i cant wait to go to my salesman come monday and have a nice talk with him, he hooked me up on my ss/sc hell do the same for my ss/tc haha i love chevy for doing this... I was hopin they would do this

damn you, you beat me. :(

I might be getting me a balt when these come out :D GM better give us white!!!!

Autoblog has a lot of info on it at this site.

http://www.autoblog.com/2007/10/28/officially-official-2008-chevy-cobalt-ss-bows-at-sema/

hmmm ss sedan... finally someone gets it lol there's a new SRT4 neon in town boys and girl... now if they'd just drop the LNF into the astra they'd have a full market and be set... astra to take out the focus and fugly new STI hatch, balt to take out the other part of the crowd WTG GM ... finally you listened.. well maybe depending on actual pics of the car

multiple threads merged

They did reduce the final drive though to 3.82 . I think this trans will work well with the LNF .

The axles for 2008 are new .

Still way too short for the LNF's powerband.

BTW - A Bone Stock LNF should run similar times to a S2 LSJ SS

Finally! I'll be at SEMA this week, so i'll try my best to get some good pics of it all for us here. A demonstration would be cool too.. but i doubt it'll be much of a runner.
Anyone else going to SEMA?

Will it come in Auto? i want a car for every day driving and traveling and where i live i would hate to change gears 9,000 times.

I agree with you there....VA sucks for driving!! The only state I ever been in that I can drive about 70mph and in a second go down to 5:thumbsdow

Did they mention what the price point on this Cobalt was going to be?

Has anybody seen any gm upgrades for the turbo yet?? Like kits and exhaust?

A crappy 4spd auto most likely. If gm won't give us a 6spd manual. There's no way were getting anymore more then a 4spd auto.

The Sky Redline and Solstice GXP have a 5-speed automatic as an option.

I think that this is BADASS! I love turbos & superchargers! I can only imagine what stage kits GM might come up with...

hope they're better than the crap they came up with for the sc

Nice love how they boosted up the power. Wonder what the other sport compact cars will do now in their models to put up a fight towards Chevrolet.

And it'll so much easier to upgrade turbos IMO. I rather upgrade a turbo than a pulley. Plus you get that extra power for not having a S/C on the engine. I love turbos! Too bad this car will probably be up around $25K.

those rims are fugly

theres another thread about the turbo balt and has all the colors listed

We probably won't see GM upgrades until the first ones start rolling off the car lots. 80% of time they'll make a couple hundred pre-order kits then when they see a huge interest then they'll start rolling out the stuff.

Even after a year on the market...I really wasn't impressed with what upgrades GM had to offer when I bought my car in 06.

I KNEW IT ;)

Sounds like alot of worthy upgrades over the S/C SS. Just hope the rims are the ones in the spy pics we have seen.

The Sky Redline and Solstice GXP have a 5-speed automatic as an option.

thats a RWD transmsison. GM has moved on towards 6 speeds, even in FWD but one has yet to be fitted to a small car application--possibly won't fit.

Here's the offical paper on the GM site

Who will be the first 35r is the only question that matters...35r should yield 500 hp with minimal upgrades.

White sounds good. I think the Imperial Blue is the dark blue I've seen a few base model 07 Cobalts around town in. As far as interior, picture an 07 with those HHR SS seats. Can we get a better looking E-brake?? Wheels from the release pics are fugly. Stick to the original wheels or maybe a thinner five spoke. Brembos sound good, but why not all around (Wonder if the GMPP drilled rotors will fit)?? Hopefully the upper and lower air dam will have the diamond mesh insert as well (never understood why the horizontal lines in the front and the diamond mesh in the lower rear skirt)... I still want the 09 CTS-V, but I could definately trade in my 05 for one of these as the daily driver... :cssNET: :cssNET:

more small tid bit comparisons .

08 curb weight = 2975 , compared to the 2806 GM officially lists for the 2005 .

Steering ratio 2005-07= 16.63:1 compared to 08 @ 14.8:1

anyone know the price on it

is the 14 compared to the 16 steering ration significantly faster? This no lift shift feature blows my mind. Is this something that has been on other cars that I have just never heard about?

Id love to see if new axles come out that will work with the S/C's too. I wonder how tapped out the motor is like if GM will really release any kits other then basic intake and exhaust. 0-60 sounds good though! Id love to run one stock with my stage 2.

It shouldn't be much more than the 07 SS/SC

I think "no lift shift" is another one of those features is going to be a big lure for people who probably shouldn't be driving fast cars resulting in rediculous insurance rates for everybody who buys one.

But this comes from the same guy who opted out of ABS.

do you think wheel hop will be a problem with this car, or will mods be needed to rid of it?

do you think wheel hop will be a problem with this car, or will mods be needed to rid of it?

normally I would say wheel hope wont be a problem as it's a turbo'd car and generally they don't have that problem.. however according to the data sheet it makes 260 ftlbs at 2000 RPMs ... thats more power then the LSJ soooo yea it might be an issue lol

I really hope they make the G5 Gxp version with this engine because I will trade my car in for sure once i get it paid off.

Ah crap. i was hoping to get the ok from my contact at GM to go ahead and tell everybody the rumor of the turbo was fact. I have know for a long time it was coming.(not that you`ll believe that)
I also had a direct influence on white being available for the SS/TC aswell.(not that you`ll believe that either)
But I am glad its been finally announced to stop the insanity of rumors and speculation.
Can`t wait to get to drive one in the spring.

27'th,

Sounds like you have some behind the scenes knowledge about the car. What is the story on the rims? The rims in the test mule pic's are awesome - are they going to be available?

In the autoblog, they say that wheel hop and torque steer has been reduced greatly, due to the changes they have made to the FE5 suspension.

And I think we would all like to know about the Vette style rims.

A different shifter arrangement... hmm .. sounds like a "crappier" shifter arangement. I hope it won't look like this:

You're probably right. The HHR SS has a 4 speed auto (with only 235 horsepower) so if there's a Cobalt SS Automatic, that's probably what we'll get, too.

I always trusted your knowledge... :ca:

HA!! 500hp on this motor can't be done with just a 35R, you're gonna need a GT4082 because of the way this motor flows. You're also gonna need a ported shroud, and a relatively low turbine A/R. But that is an entirely different story, because you will need different injectors (stock max 27-28psi) and those bad boys are gonna cost a pretty penny. But understand, for 500hp, you will be running around 40psi!!:eek: I wouldn't want to be the one to find out if those cast aluminum pistons would be able to take 40psi.http://i165.photobucket.com/albums/u43/ArchienBalt/smilies/gunnrounds0.gif?t=1193681776

Definately!! This thing will turn on a friggin dime!

Those wheels have always been available as an option.

HAHAHA,ya right. I just thought it would be cool to be able to drop the info on here first before the official release. Oh well, i promised i wouldn`t say anything.And i always keep my promise.;)

Sorry I just had to post this...gosh darn it, they're making it white!!!!! UGH! That will uber sexalicious. Now I gotta keep my balt silver, I was gunna paint it white to be unique. :lol: No more on that. This car its going to be nice, I still want to know about switching out the head of the LNF and putting it on the LSJ, if its possible with the DI and all. It looks kind of un sport IMO, but I sure as hell want that front grill and I may do some interior switches with the SS/tC. Glad GM is keeping the car, good luck to all the people buying this car, and remember, we're all balts, no tc vs sc stuff. Keep the balt love goin! :cssNET:

Alot of the interior descriptions were worded around the fact the Cobalt SS technically doesnt exist in 08 . So stuff like the guages , the shifter ect. are being described as different or upgraded compared to the 08 Cobalt Sport , but really the same as always . The front seats and the bolstered rear seats are brand new and thats basically it .

The only changes im really worried about with this car is the motor :) .. hopefully it wont have many bugs when its first released

From the newest press release (How many releases will Chevy make??) :lol:


Engineered to offer more than merely a turbocharged rush of power, an all-new FE5 Sport suspension was developed and includes specific stabilizer bars, spring rates and damper tuning – all designed to complement the high-output turbocharged powertrain and mitigate afflictions such as torque steer. Driver-selectable modes help maximize performance whether on the street or track.

Hmmm... "Driver Selectable"?? Will this be a switch to defeat the Stabilitrak and simultaneously tune the suspension, or it is a wrench mod that should be made say before you hit the track?? Also, gotta love that the torque steer is mitigated. I'll miss it though... :cssNET: :cssNET:

Anyone notice that Chevy's statement said the '08 Turbo 'Balt won't be released until the 2nd quarter of 2008?

That actually makes it a 2008.5.

Look at the new SRT-4. It's also an '08 model but it will be rolling down the assembly lines in about a month or so.

A Switch . Normal , Sport and off . You can completely turn off the stabilitrak in the Cobalt SS . ITs controlled thru the info center . Stabilitrak works thru the ABS and traction control at each individual wheel , not the suspension .

When will GM start taking orders for them?

Anyone familiar with Stabilitrak? Can you switch through the modes on the fly?? :cssNET: :cssNET:

stabilitrack is not what you think. It tries to prevent you from getting into trouble. It might have an off switch. It's not a driver selectable suspension setting gizmo.

I see in the SEMA pics those tires are Continentals, probably ContiSportContact 2s. I say swap those for the Bridestone RE050s or the Michelin PS2s. :cssNET: :cssNET:

wat is the part number on those 18 inch rims on the LNF balt?

Which "LNF Balt" are you referring too? The actual LNF with teh 5 twin spoke wheels that aren't avaiable yet? Or the one shown on this page with those disgusting polished rims?

ya not the polished nasty rims.
the ones that were on the sema balt...guess those arnt available yet.

They arent available yet , but there is a part # for them . Frk33(sp?) made a thread about all the 2008 Turbo SS part #'s in his GM computer awhile ago . THe part # is in that thread .
