The Pontiac line-up loses two vehicles in 2007. First departure from Pontiac is the Montana SV6 minivan. Second, despite considerable fanfare and build-up to the return of the GTO in 2004, the V-8 powered, rear-wheel drive coupe failed to attract sales. The Pontiac GTO has been dropped in 2007 after a three-year performance run. Pontiac's recently-introduced, fun-loving roadster the Solstice is awarded even greater performance credibility in 2007 thanks to a new GXP trim level. The 2007 Pontiac Solstice GXP model is propelled by a turbocharged 2.0-liter Ecotec four-cylinder engine that feeds 260 horsepower to the car's rear wheels. Taking the place of the Sunfire, the all-new Pontiac G5 is delivered in 2007 only as a two-door coupe. In its second year on the market, the Pontiac Torrent receives a more robust level of standard safety equipment for 2007 with traction control, four-wheel disc brakes and anti-lock braking system. The Pontiac Vibe loses its available all-wheel drive system for 2007 leaving just a front-wheel drivetrain.
