Year to Year Changes
2006 Pontiac G6:

A price-leader 1SV sedan arrived with a 167-hp 4-cyl engine. At the top of the G6 roster, GTP coupes and sedans had a 240-hp V6 (GTP convertibles had 227 hp) and optional 6-speed manual transmission.
2007 Pontiac G6:
Pontiac's best-selling car got some new and more-powerful engines for 2007. GTs had a 3.5-liter V6 rated at 224 hp in sedan and coupe, 217 hp in the convertible; it up from 201 hp in 2006. For '07, GTPs traded the 3.9 for a 252-hp 3.6-liter V6. Curtain side airbags were now standard instead of optional on sedans and coupes.
