2008 Pontiac G8 Powertrain: Pros
Year	Body/Powertrain	Comment
2009	4dr Sedan 415-horsepower 6.2L V8 6-speed shiftable automatic RWD	Most powerful sedan for under $40k. Beats any stock 4.6L Mustang, any Charger/300, and even most European sports sedans short of M5/AMG/RS or the $100K crowd. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	A fast "thirsty" engine when you need it, BUT also an efficient 25mpg cruiser on the highway (thanks to AFM) when just coasting along! see full Pontiac G8 review
2009	4dr Sedan 415-horsepower 6.2L V8 6-speed shiftable automatic RWD	There is nothing more special than beating out a Mustang GT or Charger! see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	The 361 horspower, going thru a 6 speed auto to rear wheel drive! Lots of get up and go but with reasonable fuel mileage if you drive reasonably. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	Strong and smooth. The Sport and manumatic tranny options are a big plus. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	This thing is brutally fast. It accelerates with ease, and you always feel like you have torque to spare, even at highway speeds and in normal shifting mode. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	Its like a Corvette with 4 doors. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	LS2 variant L76 V8 attached to Corvette derived 6-speed automatic and rear end. Really, what else is there to say? Gobs of power launches this two ton rocket 0 to 60 in 5.1 to 5.4 seconds. Baby it on the highway and you can eek out 24 MPG. see full Pontiac G8 review
2009	4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD	Smooth and fast power delivery. GOBS of torque from off the line. see full Pontiac G8 review
