With its three turbochargers, the current BMW Tri-turbo diesel enjoys a special position in the high-end premium market, yet the engineers in Munich have already put together a worthy replacement. BMW is rumored will launch a quad-turbo straight-six diesel for the 2016 BMW 750d. Other future 50d models are also likely to use the same unit.
If you listen to different sources, the engine is either labeled as B57 TOP or B57S. Currently, we don’t know the full technical specs of the upcoming engine, therefore we can’t comment on whether BMW will offer four classic turbochargers or an electrically-driven turbo being added to the previous tri-turbo setup.
But one thing we’ve learned this week is the power output: 395 horsepower.
The current six-cylinder in-line diesel engine comes with three-stage turbocharging and common rail direct injection. From a 3.0-liter displacement it develops output of 280 kW /381 hp and a peak torque of 740 Newton meters (546 lb-ft).

First model to get the updated engine is the 2016 BMW 750d.
Just like the current Tri-turbo, the new BMW quad turbocharged diesel will always be linked to the all-wheel drive system xDrive.
its a shame M dont make brand new engines for new M cars.. always the same TT V8.. i’d like to see something new.. like they did in the past
Well the past isn’t a good example: they based almost all the models from E24 to E30 M on the same engine platform, and then did it again with another one from E36 to Z4 M, then they did it another time with E60/E92.
Now they have the S65Tü architecture and components they took back from the first X5 M, and use it every where even M2.
Next one will more likely be a hybrid type of thing.
Why would you do that? Why chang something which is still perfect? What would you have more than good fuel efficiency, power, sound? Just to have something new?
its a masterpiece engine yes but i liked when they made a new engine per car
uh… it might still be a V8, but it’s also twin scroll twin turbo now … that’s a pretty complex beast. why create something new if you can keep pushing the limits with more boost and less weight?
yes its a beast but M used to make a new engine for each car
Damn that’s almost the same Specific output as the S55 ! For a diesel engine !!
