Page 1 of 1 GTO - the original muscle car - was re-introduced for 2004 and returns with more power and style for the 2005 model. 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 - up from 350 horses - and 546 Nm of torque, up from 495 Nm. Transmission choices are the same as the '04 model's: The Hydramatic 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.
Enthusiasts will immediately spot the brawnier '05 GTO, thanks to new badging and a revised rear fascia that incorporates a new dual-exhaust system - it splits the GTO's two outlets, routing them to opposite sides of the rear fascia. The exhaust tips are polished for a more refined appearance. Also available is a new hood design incorporating a pair of stylish air scoops. The scoops draw fresh air in to the GTO's engine compartment.
The badges identifying the '05 GTO's bigger V-8 include a "6.0" badge on the trunk lid and revised "GTO" fender badges, which now incorporate "6.0 Litre" designations. The original 1964 GTO also wore "6.0 Litre" fender badges, but at a time when almost every other American manufacturer referenced engine size in cubic inches. Along with the GTO's power increase comes improved braking performance from larger brake rotors, calipers and pads. The calipers are painted red and the front calipers feature the GTO logo.
Additional changes to the '05 GTO include two new colors (blue and grey), as well as driver foot rest. A line of regular production accessories (RPAs) based on the 2004 GTO Performance Plus SEMA concept vehicle is scheduled for start-of-production availability. The accessories include a tall rear spoiler, front and rear fascia extensions, rocker molding extensions and grille inserts. As part of GM's RPA program, the accessories can be ordered and installed on the vehicle prior to delivery. Page 1 of 1
