BMW Unveils Quad Turbocharger Diesel Engine

[New Engine For 7 Series Gets 4 Turbos]

In current years, automakers have begun to introduce multiple turbochargers in their luxury engines in order to give a boost to performance as well as to reduce emissions. These may range from one, two and even three turbochargers at once.

Until now, only Bugatti has tried to experiment with four turbos in one engine, but now In current years, automakers have begun to introduce multiple turbochargers in their luxury engines in order to give a boost to performance as wll as to reduce emissions. These may range from one, two and even three turbochargers.

Until now, only Bugatti has tried to experiment with four turbos in one engine, but now BMW too is jumping into the quad turbo segment with it’s new Quad-Turbocharged 3.0-liter inline six engine for the 7 Series.

Built for the 750D, this diesel engine improves great over it’s previous iteration, with five percent more power that tops up at 294 kW (400 hp) available at 4,400 rpm. The real winner however is the 760 Nm (560 lb.ft) output, with 450 Nm (332 lb.ft) on tap from idle, making for a smooth yet powerful ride.

When pushed, all that power gives you a great headstart, with the car hitting 0-100 km/h (62 mph) in 4.6 seconds.

This amazing figure is achieved with the help of two variable-geometry turbos that work in tandem with two low pressure turbos. The high pressure turbos are only put to work when you really push the pedal to the metal.

The rest of the time, only the low pressure turbos, and one high pressure turbo is used to provide great performance without putting a lot of stress on the engine.

Managing all these changes is the duty of the Digital Diesel Electronics Controller, which works overtime to make sure that the engine is finely tuned for whatever demands you may ask of it.

All this power and performance doesn’t mean that the car is a gas guzzling white elephant. On the contrary, due to the four turbos, the fuel economy is claimed to be approximately 5.7 l/100 km (49.6 UK MPG), making it one of the more environmentally conscious luxury cars to buy.

If you feel that you need to own such an amazing and striking beauty, then you’ll have to wait till June, when the 750d xDrive will be launched in both regular or long wheelbase variants. For more information, contact BMW.
