Pontiac GTO

The original muscle car

GTO – the original muscle car – was re-introduced last year and returns with more power and style for 2005. A new LS2 6.0L V-8 engine replaces the LS1 5.7L engine, bringing with it an increase in horsepower and torque.

The ’05 GTO packs 400 horsepower (298 kw) – up from 350 horses (261 kw) – and 400 lb.-ft. of torque (542 Nm), up from 365 lb.-ft. (495 Nm). Transmission choices are the same as the ’04 model’s: The Hydra-Matic 4L60-E four-speed automatic is standard and the Tremec six-speed manual is optional. GTO’s more powerful engine should lower the 0-60 time to less than 5 seconds.
