2005 Mercedes-Benz Vision R63 AMG Concept

Mercedes-Benz's efforts at this year's Frankfurt show can be described as little less than heroic. For the 61st event, the Stuttgart-based automaker will be showing a large number of new cars, crossovers and SUVs, including some of the fastest all-weather, all-terrain vehicles any road has ever seen. Included on the bill is the new R-Class crossover vehicle with available 5.0-litre V8 power, plus the all-new S-Class with a biturbo V12.
