Mercedes-Benz has issued these first official photographs of its upcoming M5-rivalling CLS55 AMG. Based around the same mechanical package as the rapid E55, the CLS55 will be out to keep the new M5 honest. Powering Stuttgart’s bahnstormer is AMG’s supercharged 5.4 V8 which delivers 476bhp and 516lb ft of torque. Mercedes claims 0-62mph acceleration in 4.7sec and a top speed limited to 155mph. The new car rides on a tuned version of Mercedes’ Airmatic DC air suspension, and 18-inch double-spoke alloy wheels. Further extending the standard CLS’s aggressive appearance is an AMG bodykit consisting of a deeper front apron with integrated fog lamps, unique grille with three silver elements, wider side sills and a reworked rear bumper with dual oval tailpipes. The CLS55 is scheduled to go on sale around Europe in January at a price of €96,164. Mercedes hasn’t announced timing for its UK introduction, though it is unlikely to land before April 2005; expect a price tag of £67,000.
