First developed by Holden in 2004, GM’s Zeta platform now underpins vehicles as diverse as the Statesman/Lumina/G8/Caprice sedans, and the Chevy Camaro. Originally designed for full-sized , rear-drive Australian sedans, Zeta was downsized as far as it could be for the Camaro, which reviewers largely view as overweight and rather too ungainly for true sportscar status. Accordingly, GM has been developing a new rear-drive platform known as “Alpha,” which will form the basis of GM’s performance and luxury RWD models for the considerable future. Last we heard about Alpha was last August, when Bob Lutz swore there was no development underway of the platform he compared to BMW’s 1-/3-series. According to Motor Trend, work on the Alpha platform has begun… but there are already signs of trouble.
