The name Sigma Lite has been out of use for some time. The chassis is internally referred to as Global Volume RWD, though it is AWD capable. It is also referred to as Zeta II or simply Zeta as the original Zeta plan was killed some time ago. There will be different versions of this chassis produced all over the world. It will replace the Holden VE architecture after about 5 years. The first Global Volume RWD will be either the 2009 Chevrolet Impala or 2009 Chevrolet Camaro. Both will feature a double pivot McPhearson front strut suspension, modified from Holden's VE, and an independent rear suspension system very similar to that of Sigma II but using cheaper steel rather than aluminum to save cost. Expect GM to use the 3.6 L HF V6 across the board with these vehicles as well as the current V8 out when they reach production.
