BMW has announced a limited edition of super lightweight M3 sedans powered by an enlarged and more powerful version of the iconic performance model’s naturally-aspirated V8.
Just 67 examples of the M3 CRT (Carbon Racing Technology) will be produced; all four door sedans, weighing in at just 1580kg (45kg lighter than the standard model) thanks to the extensive use of carbonfibre reinforced plastic (CFRP).
Engine capacity has been increased from 4.0 to 4.4-litres (cylinder bore increased from 75.2 to 82.0mm), lifting outputs to 331kW/440Nm (up from 309kW/400Nm).
The result is a claimed 0-100km/h time of 4.4sec, fully half a second quicker than the ‘normal’ four door M3. Vmax is electronically capped at 290km/h.
