The mission of the G6 is to beat the Honda Accord, Nissan Altima and Mazda6 on value, a proposition bolstered by GM's lower prices for 2006. While the G6 doesn't offer the refinement or attention to detail of its Japanese rivals, it's an alternative worth considering for shoppers in the mid-size car market. (The G6 replaces the Grand Am, which has been discontinued.)
The G6 sedan line has been expanded for 2006 as well, with multiple engine and trim levels available. Engine choices for 2006 include a 2.4-liter four cylinder for the base model, the 3.5-liter V6 that comes on the GT, and a 3.9-liter V6 with variable valve timing for the new GTP models. Transmission choices include four-speed automatics for all three engine choices and a six-speed manual for the high-performance 3.9-liter GTP.
