Completed over a year ago on paper, the supercharged rebirth of the Camaro Z-28 has been on hold as the industry and economy suffered. But it's a definite go according to GM's vice president of global vehicle engineering Karl Stracke, according to a report this week.

The Z-28 has previously pegged to get the 6.2-liter supercharged LSA V-8 engine also found in the Cadillac CTS-V, where it's good for 556 horsepower and 551 pound-feet of torque, as well as 3.9-second 0-60 mph runs in the CTS-V Coupe. Of course, the Z-28 is likely to weigh a couple hundred pounds less than the more luxurious CTS-V, so it may dash about even quicker.

Beyond the upgraded performance, the Z-28 is also expected to get a more aggressive exterior appearance than the current SS, including larger air intakes, front splitter, rear spoiler, and unique interior treatments, with Z-28 badges inside and out.

Other Camaro news from Stracke includes confirmation that the next-gen Camaro will move to the upcoming Alpha platform that's set to underpin Cadillac's upcoming ATS smaller luxury sedan as well as--possibly--the next-gen CTS. This could mean a lighter, slightly more compact Camaro due after 2013 or 2014, as the industry works toward ever tighter fuel economy and emissions requirements imposed by the government.
