Stop wondering whether or not GM will put its 2.0-liter direct-injection turbo four into the Cobalt SS, replacing the current model's supercharged mill. The SAE test spec says it all, that is, 262 horsepower at 5000 RPM and 261 lb-ft of torque at 2000 RPM. Telltale numbers, indeed. Now we just have to wait until 2008.5. Is that a leap year?
