Two versions of the 2007 Pontiac G5 coupe will be sold starting this fall. The base coupe will be powered by a 16-valve, dual overhead cam, 2.2-liter four-cylinder engine offering 148 horsepower at 5,600 rpm and 152 lb.-ft. of torque at 4,200 rpm. For a bit of excitement, buyers can opt for a GT model and its 16-valve, dual overhead cam, 2.4-liter four-banger good for 173 horsepower at 6,200 rpm and 163 lb.-ft. of torque at 4,800 rpm. With both engines, a five-speed manual transmission is standard while a four-speed automatic is an $850 option. Oddly, given that Pontiac is supposed to be GM performance-oriented division, a supercharged 2.0-liter like that in the Cobalt SS Supercharged and Saturn Ion Red Line will not be available.
