Mercedes has announced the 2007 Mercedes G 55 AMG, an updated version of its high-performance off-roader, now with 500 horsepower for the new model year. The supercharged 5.5-litre AMG engine generates its maximum torque of 700 newton metres between 2750 and 4000 rpm. These exceptional figures allow the truck to accelerate to 62 mph in just 5.5 seconds. Visually, the new model year G 55 AMG is distinguishable from its predecessor by 18-inch AMG light-alloy wheels painted in titanium grey with 285/55 R 18 wide-base tyres. Standard appointments now include bi-xenon headlamps, oval foglamps with a cornering light function and ISOFIX child seat attachments in the second seat row. The more scratch resistant, nano-technology based paint finishes of calcite white, periclase green metallic and teallite blue metallic are also new.
