Displacing 4.4 litres, this supreme eight-cylinder with BMW TwinPower Turbo
Technology plus High Precision Injection delivers a supreme 300 kW/407 hp
in the speed range between 5,500 and 6,400 rpm.
Torque reaches a peak of 600 Newton-metres/442 lb-ft maintained
consistently between 1,750 and 4,500 rpm.
The V8 featured in the new BMW 550i is the most efficient engine of its
kind and, at the same time, the only petrol engine in the world to feature
turbochargers and catalytic converters conveniently housed in the V-section
between the two rows of cylinders. This alone ensures particularly short
distances between the turbocharger and the intake manifold and, together
with the water-cooled intercoolers, gives the V8 an exceptionally spontaneous
and direct response.
The all-aluminium power unit combines supreme thrust cutting in at an
early point and then continuing throughout a long range with exceptional
smoothness and refinement. The BMW 550i accelerates from a standstill
to 100 km/h in just 5.0 seconds and offers adequate power reserves also at
higher speeds for a continuing process of smooth and dynamic acceleration.
Top speed is limited to 250 km/h or 155 mph by the electronic control unit,
average fuel consumption of the BMW 550i in the EU test cycle is
10.4 litres/100 kilometres (equal to 27.2 mpg imp) and CO
243 grams per kilometre.
Six-cylinder petrol engines: setting the standard for fast-revving
response, smoothness, efficiency and innovation.
Modern straight-six petrol engines guarantee up-to-date driving pleasure also
in the new BMW 5 Series. The power units in the BMW 535i, the BMW 528i
and the BMW 523i all combine spontaneous power and performance with
unique revving qualities, outstanding efficiency, and supreme smoothness.
Delivering 225 kW/306 hp and offering a unique technological concept,
the most powerful six-cylinder in the new BMW 5 Series clearly confirms
both the sporting character of the sedan and the innovative power of
BMW's engine development specialists. Indeed, the 3.0-litre six-cylinder
in the BMW 535i is the first engine to combine BMW TwinPower Turbo
Technology, High Precision Injection, and variable VALVETRONIC valve
management. The turbocharger system applying the TwinScroll principle
to separate the ducts of three cylinders at a time both in the intake manifold
and in the turbocharger itself, as well as VALVETRONIC valve drive
developed to an even higher standard, ensure a fascinating response at
all times.
