The future of diesel engines in the United States and possibly elsewhere is in doubt as a result of ongoing emissions cheating scandals, but automakers aren’t giving up on the technology just yet.

At the recent 2016 Vienna Motor Symposium, BMW presented a quad-turbocharged 3.0-liter inline-6 diesel engine delivering 394 horsepower and 561 pound-feet of torque (triple-turbocharged engine shown).

Full details are yet to be announced but according to Bimmerpost the engine will replace the triple-turbocharged unit BMW currently offers on some high-performance diesel models sold overseas. The triple-turbocharged engine, also a 3.0-liter inline-6, produces 381 hp and 546 lb-ft.

More power, less consumption

The new engine is said to utilize two low-pressure turbos and two high-pressure turbos whereas the previous design used two low-pressure turbos working in conjunction with one massive high-pressure turbo. The result is not only improved power and torque but also reduced consumption, reportedly around 5 percent lower.

The new engine will make its debut in a 750d xDrive. It will likely also end up in some M Performance models from the German automaker such as a new M550d based on the next 5-Series and new M50d models based on the X5 and X6.

Stay tuned for an update.
