MUNICH: BMW wants prospective buyers of its M3, M4 Coupe/Converible to know that the carbon fibre reinforced plastic driveshaft in the cars would be replaced by an M specific high-performance driveshaft made of steel from November.

The move is aimed at meeting future statutory emissions requirements, it said. Combined fuel consumption figures for the M3, M4 Coupe/Converible are 9.5 – 8.3 l/100 km, while CO2 emissions is rated at 218 –194 g/km.



The driveshaft change would be followed by the introduction of a petrol particulate filter (PPF) into the existing installation space in these models in major markets. This measure does not apply to the M4 CS and M4 GTS special-edition models.

BMW claimed the newly developed steel driveshaft has been designed to ensure exceptional performance and handling qualities of the M3/M4 sports cars.

Now in their fifth generation, customer deliveries of the current generation of models have now topped 68,000.
