The following is the official GM press release on the 272 Concept:

2004 CHEVROLET COBALT SS 272 CONCEPT 10-30-2004
With the production SS Supercharged arriving in dealers later this year, GM Performance Division has already been tweaking. Never a group that can leave well enough alone, Performance Division’s modus operandi can be clearly seen in the Cobalt SS Supercharged Coupe. This vehicle was created to demonstrate the potential for street performance. The subtle exterior treatment of this show vehicle cloaks a host of engineering upgrades that yield significant improvements in acceleration and handling. Horsepower hits 270, larger brakes spin at the ready, and a lowered suspension steadies the chassis. Carbon fiber cues hint at the performance potential of this complete package.

Vehicle Highlights
• Supercharged and intercooled 2.0L engine producing 270 horsepower
• Functional fresh air intake integrated into hood
• Fabricated air intake box
• Low-restriction exhaust system from the catalyst rearward
• Traction-enhancing limited-slip differential added to the heavy-duty five-speed manual transmission
• Suspension lowered by 40 mm (1.6 inches) and tuned by GM High Performance Vehicle Operations (HPVO)
• Large-diameter four-wheel-disc braking system with Baer rotors and production calipers
• 19-inch wheel and tire package
• Audio system with Pioneer Electronics speakers and Alpine amplifiers
• Aftermarket Motorola cell phone with IHF 1000 Premium Car Kit
• Re-trimmed, custom interior that highlights SS heritage
• Exterior styling that explores new concepts based on production Cobalt SS Supercharged
