With the pending arrival of the F10 M5, it’s now open season for future M-car model speculation and the latest rumour doing the rounds is that of a diesel-powered saloon model with all-wheel drive…
According to a report in the Detroit Bureau, insiders at BMW have hinted at the company’s desire to produce its very first diesel-powered M-car. Citing BMW global marketing manager, Brian Watts, who stated that the company is “looking at” a diesel option due to its “interesting potential”, the report is very much scratching the surface of the issue.
The idea of a diesel-powered M-car will, no doubt, meet with firm resistance from purists who see the M division’s creations as vessels for powerful petrol engines coupled with rear-wheel drivetrains but, given the ever-tightening nooses of emissions legislations and rising fuel costs, the presence of diesel powerplants in the performance sphere is fast becoming less far-fetched.
It has been suggested that the oil-burning M-sedan will be powered by a reworked version of BMW’s 3,0-litre twin-turbo diesel engine, possibly featuring an additional turbocharger and modifications to the cylinder heads, ECU and other ancillaries.
The sources within BMW have admitted that the diesel M-saloon will not equal the M5 in terms of power, instead majoring in torque where it will eclipse the petrol car’s 680 N.m of torque to the tune of an additional 200 N.m. Getting a car with close to 900 N.m off the line cleanly will be no mean feat, and that’s where the all-wheel-drive element comes in. According to Watts, the powertrain option consideration is “not finished [yet].”
Should such a model get the go-ahead, it could possibly emerge towards the tail-end of 2013.
