The M3 is a favourite of car enthusiasts. Its race heritage dates back to the 1980s, although at first the 2007 model seems far too well mannered to play the part of a road-going race car. There are some muscular styling additions to distinguish it from the standard 3-Series, hinting at the car's potential. But at a time when most people seem to be concerned about carbon footprints than a carbon-fibre roof, BMW has performed the trick of increasing engine size and power output, while reducing fuel consumption and carbon dioxide emissions. However, the M3 remains a thrilling drive and certainly able to stake a claim as the best driver's car in its class in the face of ever stiffer competition from Audi and Mercedes-Benz.
