For the record, the new M3's unladen EU weight (including 68kg for driver, 7kg for luggage and a 90 per cent full fuel tank) rises a considerable 85kg - from 1570kg to 1655kg. BMW Australia quotes kerb weights of 1495kg (E46 M3) and 1580kg (E92 M3) respectively.

BMW says the extra weight is the result of the bigger two-door body, extra equipment and superior crashworthiness – but points out it is still 100kg lighter than its most direct rival in the Mercedes-Benz CLK63 AMG coupe (1755kg).

However, the model that has established Audi as a serious player in the compact performance car stakes in recent times, the wild RS4 sedan (also available in Avant and Cabriolet bodystyles), weighs 5kg less at 1650kg, packs a larger 4.2-litre V8 with the same 309kW and even more torque (430Nm) and comes standard with all-wheel drive."
