For the first time the six-cylinder in the BMW 535i combines
BMW TwinPower Turbo Technology and High Precision Injection with fully
variable VALVETRONIC valve control. The result is infinite adjustment of
valve stroke and valve timing on the intake side, reducing throttle losses in
the charge cycle to a minimum and making particularly efficient use of
the energy in the fuel. A further advantage is the response of the engine
optimised to an even higher standard.
Developing 225 kW/306 hp, the power unit featured in the new BMW 535i
accelerates this outstanding sedan to 100 km/h in 6.0 seconds, combined
with average fuel consumption in the EU test cycle quite unique in this class
of just 8.5 litres/100 kilometres, equal to 33.2 mpg imp.
The permanent, ongoing development of drive units in the context of
BMW EfficientDynamics also means the optimisation of weight. Hence,
the drive units in both the new BMW 550i and the new BMW 535i are
made largely of aluminium, while the straight-six engines in the BMW 528i
and the BMW 523i come with a composite magnesium/aluminium crankcase
again some 24 per cent lighter than a comparable aluminium block.
Such optimisation of weight benefits not only the efficiency, but also the
agility of the respective vehicle. All versions of the new BMW 5 Series Sedan
come with almost perfect 50:50 weight distribution front-to-rear. In
combination with rear-wheel drive, such harmonious axle load distribution
is indeed crucial to the dynamic and, at the same time, superior driving
behaviour of the new BMW 5 Series Sedan.
Full of torque, light, efficient: the latest generation of diesel engines.
The diesel versions of the new BMW 5 Series Sedan also offer state-of-the-
art drivetrain technology. All-aluminium construction, common-rail direct fuel
injection of the latest generation and turbocharging give both the four-
and six-cylinder diesels truly impressive torque and pulling force, supreme
smoothness and unparalleled efficiency.
The BMW 530d and the BMW 525d come with two representatives of a
new generation of straight-six diesels – outstanding power units featuring
a wide range of innovations for unusually efficient and clean combustion.
Further weight reduction compared with the former engine in each case
also serves to improve the efficiency and agility of both models.
Both engines displace 3.0 litres and come with an optimised turbocharger
system with variable intake geometry providing superior power and torque
from an early point. Fuel supply through common-rail direct injection of the
