BMW: Incoming tri-turbo diesel

The introduction of an engine equipped with tri-turbo dedicated to the next generation of the BMW M3, according to rumors will be anticipated by the arrival of a powerful 3.0-liter diesel unit features triple boost. This sophisticated, the original engine should use the two-stage turbocharger used on many of TwinPowerTurbo BMW models, coupled to a third electric supercharger called the Bavarian manufacturer VTES (Variable Torque Enhancement System).

The electric compressor works like a normal turbine that operates the rotation of the compressor, but it remains independent of the speed with which the exhaust gas is introduced, eliminating the main weakness of the supercharger, ie the classical vacuum of power registered under 2000 -3000 RPM, known as "turbo lag".

The all-new 3.0-liter engine should deliver a tri-turbo power of 400 hp and will be installed during 2012 on the flagship 7 Series, named for the occasion and also proposed 750D-wheel drive variants (xDrive) and long wheelbase , and then will make its debut on the X5 and X6 SUVs.
