BMW has embraced diesel engines with their new M Performance Automobiles sub-brand, but AMG is charting a different course and staying committed to petrol engines.

Speaking with Autocar, AMG's Ola Källenius said diesel engines would compromise AMG's lineup. He went on to say that recent engines, such as the twin-turbo 5.5-liter V8, are relatively efficient thanks to direct injection and turbocharging.

He added that AMG has looked at diesel engines in the past, but "petrol engines have [the] obvious benefits of sound, weight, agility and response."
