BMW’s M Division is continuing to work to significantly reduce the carbon emissions of its sports cars, and the sporting arm has not ruled out the use of diesel engines.
Development boss Albert Biermann told Autocar that while it’s still quite a far-off prospect, he can foresee a time when the continued refinement of diesel engine technology will make it suitable to power a fully fledged M car.
“With cars like the X5 and X6 M, the torque characteristics of diesel engines would make them the ideal choice, were it not for their unsporting character,” Biermann said.
“I don’t think there’s a proven business case for big diesel-engined performance cars yet,” he said, “but if that changes, we’ll be well placed to take advantage.”
M division is already working to develop performance applications of BMW’s new hybrid technology.
“Battery-assisted performance is something we’re looking into,” Biermann said, “although flywheel-driven ‘flybrids’ look more promising for us.”
