latest generation is provided by piezo-injectors operating at a pressure
of up to 1,800 bar on the BMW 530d and 1,600 bar on the BMW 525d.
Compared with their respective predecessors, the new BMW 530d and the
new BMW 525d offer an increase in engine output by 7 and, respectively,
5 kW, with average fuel consumption in the EU test cycle down by up to
4 per cent.
As an option the new BMW 530d with automatic transmission may be further
upgraded by BMW BluePerformance Technology. Offering this unique
system, BMW is once again increasing its lead in the introduction of exhaust
gas management, substantially reducing nitric oxide emissions (NO
X
) to an
even lower level.
On the new BMW 530d with BMW BluePerformance, the diesel particulates
filter and the oxidation catalyst likewise featured as standard are
supplemented by an NO
X
storage catalyst operating without the slightest
maintenance throughout the entire lifecycle of the car and not requiring
any additional operating media. As a result, exhaust management of this
standard already reduces nitric oxides to the level not required by law until
the introduction of EU6 in 2014.
Consistent enhancement of its four-cylinder diesel also gives the new
BMW 520d yet a further improved balance of performance and fuel economy.
Maximum output of this 2.0-litre aluminium engine is up by 5 to 135 kW/184
hp, peak torque is up by 30 to 380 Newton-metres/280 lb-ft. At the same
time the new BMW 520d offers average fuel consumption of 5.0
litres/100 kilometres (equal to 56.5 mpg imp) in the EU test cycle and a CO
2
rating of 132 grams per kilometre (provisional figures), thus enhancing its
leadership as the most fuel-efficient and lowest-emission car in its segment.
Making its debut in the BMW 5 Series: Auto Start Stop function.
The new BMW 520d comes as standard with an Auto Start Stop function
reducing the engine idle period when coming to a short stop at road junctions
or in traffic congestion: As soon as the driver moves the gearshift lever to
neutral and takes his foot off the clutch pedal, the engine is switched off
automatically. Then, once the driver is able to go on, all he has to do is press
the clutch to start the engine without the slightest delay.
All manual gearbox versions of the new BMW 5 Series Sedan furthermore
come as standard with a gearshift point indicator. An arrow symbol flashing
on in the instrument cluster and specifying the optimum gear shows the
driver the ideal point to shift gears. Then, depending on driving conditions,
