BMW’s tri-turbo diesel powerplant is probably the most discussed subject of 2012 so far and the German carmaker has now decided to offer us a video that shows how the tree turbines work to serve the man that’s stepping on the pedal.
At low revs, the unit uses a small turbocharges that comes with variable geometry, while at medium revs a second, large turbo., is activated, in order to offer “consistently high torque”. These are followed by another small turbo further up the rev range.
We’ll remind you that the unit allows the driver to play with 381 hp and a peak torque of 740 Nm (546 lb-ft), while returning an efficiency of 6.3 liters per 100 km (37.3 US mpg) and emitting 165 grams of CO2 per km. However, what the official figures can't tell is the fact this setup also reduced turbo lag to a minimal, which brings a crucial advantage in the real world. If we couple this with BMW's xDrive AWD system, we get a machine that's capable of feeding performance over a wide range of driving conditions.
In addition to that, the new setup allows the engine to show even more personalities, as the low-end torque means that the driver can also use it in an economical way, if this is what he wants.
