Found under the hood of the BMW 550i Sedan and BMW 550i Gran Turismo, it now also combines its two twin - scroll turbochargers and high
precision direct fuel injection with BMW's Valvetronic throttle-less intake valve control.
The injection pressure in the diesel engines with common rail
direct injection is also higher and
fuel is fed to the combustion chambers with even greater
precision.
