The cheating emissions scandals may keep the future of diesel engines in doubt, but they didn’t stop BMW from developing and unveiling a new quad-turbocharged inline-six powertrain.
With 3.0 liters in displacement, it uses two low-pressure turbos and two high-pressure ones, resulting in not only more power than the tri-turbo diesel it replaces, but also in a roughly 5 percent improvement in fuel consumption.
Presented at the 2016 Vienna Motor Symposium, as Bimmerpost reports, the oil burner is good for 394 HP from 4,000 to 4,400 rpm and 760 Nm (561 lb-ft) of torque, available between 2,000 and 3,000 rpm, but maximum torque is limited by the capabilities of the 8-speed automatic transmission.
Said to make its premiere on the new 750d xDrive, the unit will allow the flagship sedan to sprint from naught to sixty (96 km/h) in approximately 4.5 seconds, with a top speed capped out at 155 mph (250 km/h).
Full details have yet to be announced, but the manufacturer is expected to add the new engine into some M Performance vehicles too, such as the M50d versions of the X5 and X6, as well as the next generation 5-Series.
