2006 GTO vs 2007 Infiniti M45
Pontiac GTO 1/4 Mile Time: 12.97 @ 118.25 vs Infiniti M45 1/4 Mile Time : 15.16 @ 92.59 The 2005 model year continued with standard hood scoops, split rear Exhaust with a revised rear fascia, and late in the year, optional 18 inch (45.7 cm) wheels. The major change for 2005 was the replacement of the LS1 engine with the LS2 engine. This 5,967 cc (364.1 cu in) engine increased power and torque in the GTO to 400 hp with 400 ft lb torque. Other changes included larger front rotors and caliper hardware from the Corvette, and the drivetrain was strengthened with the addition of a driveshaft with larger "giubos" and a larger differential flange, as well as revised half-shafts. Dashboard gauge graphics were revised. Steering wheel audio controls were added. The optional dealer-installed Sport Appearance Package became available and differed visually by having a different lower rear fascia, aftermarket mufflers with quad chrome Exhaust tips, revised spoiler and front lower fascia extension, recessed grilles, and revised rocker panels. This package was available from GM as an accessory in red, silver, black, or primer for other color cars. Production was 11,069 due in part to a shortened model year. Barbados Blue and Cosmos Purple were dropped this year, but Cyclone Grey and Midnight Blue Metallic were added. Customers also had the option to order their GTO without hood scoops (RPO code BZJ), though only 24 were produced this way. There was a 17 inch chrome wheel option. Only 17 GTOs had the chrome wheel option because this option was not offered until May 2005 and the 2005 production run ended in June. Another reason was this option was expensive, which resulted in low demand. With this improved powerplant, GM claimed the car capable of 0 to 60 mph (97 km/h) in 4.7 seconds and a 13.0 second quarter mile at 105 mph (169 km/h) (automatic transmission). Car and Driver magazine tested the car at 0-60 mph in 4.8 seconds and the ¼ mile in 13.3 seconds at 107 mph (172 km/h) for the quarter mile with its BFGoodrich g-Force T/A KDWS, 245/45ZR-17 95W M+S front and rear tires but manual transmission. The 0-100 and 0-130 times were 11.7 and 19.6 respectively.
