Chevy's next generation Camaro is going to shrink in size from its current behemoth underpinnings and share a new global Alpha platform with the third-generation Cadillac CTS and the all-new ATS. With the next Camaro due out in 2015, the CTS is destined to bow in 2013 as a 2014 model, while the 3-Series fighting ATS is scheduled to arrive just afterwards.

The news comes from a report by Motor Trend after a presentation by consultancy firm Grant Thornton LLP at the Automotive Press Association on Thursday.

Other details revealed include plans to discontinue the CTS Coupe and SportWagon, likely because both a coupe, convertible and wagon version of the ATS are in the works. The CTS will then grow slightly (by roughly 6-inches) to be more in line with the 5 Series and E-Class.

To make this plan cost effective its likely that the new Alpha platform will use different amounts of aluminum and steel depending on whether it is being used for a Cadillac or a Chevy, with the Caddy getting a higher percentage of lighter, but more expensive, aluminum.

In addition to this new MT also suggests, the 2015 Camaro SS is likely to get a supercharged or turbocharged V6, rather than a V8.
