New range topping diesel top power latest large BMW vehicles

BMW has just introduced its most powerful diesel engine to date. The new turbodiesel replaces the old tri-turbocharged engine which as found in the previous generation 750d and 750Ld, X550d, M550d and X650d. The new engine will initially be available in BMW's flagship sedan, the 7 Series.

Now packing four turbochargers, the new 3.0-liter inline-six develops 394 PS and 760 Nm of torque. According to BMW, the figures stated above are actually restricted as the 8-speed automatic by ZF will be unable to handle a larger torque figure. In addition, BMW claims that the new engine is 5% more efficient than the old triple turbocharged setup and more economically favorable to build.

The new engine consists of two large low pressure turbochargers that are assisted by two small high pressure turbos. With the quad-turbo setup, the company's engineers claim power across the whole rev range while eliminating lag. The weight of the engine is retained despite the added turbo.

As mentioned above, the 7 Series will be the first car to receive the quad-turbo diesel mill. It will soon be available in the company's large crossovers, the X5 and X6. BMW's E-Segment sedan, the 5 Series, will also get the new engine as well. An all-new 5 Series will debut during the third quarter of 2016.

At the time writing, BMW has yet to release photos of the new engine.
