BMW 535d / BMW 630i

BMW is world-famous for the company's truly outstanding straight-six
power units. And now two brand-new 3.0-litre engines are joining this
great tradition: In autumn of this year a new high-power diesel already
presented at the Geneva Motor Show featuring revolutionary turbocharger
technology will be actively launched in the BMW 535d and 535d Touring.
The second new power unit likewise entering new terrain is an all-new
gasoline engine making its debut in the 630i Coupé and
Convertible. Introducing the Variable Twin Turbo Engine in the new
535d, BMW is setting yet another milestone in the development of
automobile diesel technology: This is the first-ever twin-turbocharger
diesel power unit in a road vehicle, introducing a highly innovative
technology on BMW's three-litre straight-six. Indeed, this exceptional
power unit already proved its abilities in the X-raid team's X5 in this
year's Paris-Dakar Rally, French driver Luc Alphand not only winning
the diesel category hands down, but also finishing fourth overall.
Supreme diesel power now available at all engine speeds. The big
advantage of BMW's variable, two-stage turbocharger technology is that
it solves the old conflict of interests between high torque from very
low engine speeds and maximum power at high speeds. Developing maximum
output of 200 kW or 272 bhp, BMW's three-litre diesel achieves this
objective through the variable interaction of a small and a large
turbocharger. The small turbocharger develops high boost pressure from
low engine speeds, while the large turbocharger ensures an ongoing
increase in engine power at high speeds all the way to maximum output.
The bottom line, therefore, is supreme power in every situation. The
highly innovative engine develops its maximum output of 200 kW/272 bhp
at 4400 rpm, with maximum torque of 560 Nm/413 lb-ft at 2000 rpm.
Developing a sensational 530 Nm/391 lb-ft at just 1500 rpm, the engine
has all the power and potential of a current four-litre V8 diesel on
far lower weight and with greater fuel efficiency Compared with
a conventional turbocharged diesel, the BMW 535d comes with a broader
range of useful engine speed extended by approximately 400 rpm to 5000
rpm - again an essential feature contributing to the unusually dynamic
character of this new car entering the market in the guise of the 535d
Saloon and 535d Touring. Efficient dynamics of a new dimension. Clear
facts and figures confirm the unusual driving pleasure offered by the
world's most powerful diesel in its class: The new BMW 535d accelerates
from a standstill to 100 km/h in just 6.5 seconds (535d Touring 6.6
seconds), and despite its outstanding performance the new model offers
average fuel consumption of just 8.0 (Touring: 8.2) litres of diesel
fuel on 100 km (35.3 and, respectively, 34.4 mpg Imp), just 0.2
litres/100 km more than the BMW 530d. Top speed of the 535d is limited
electronically on both models to 250 km/h or 155 mph, high-performance
17-inch brakes ensuring superior brake power and short stopping
distances. EU 4, soot particle filter and six-speed automatic
transmission all featured as standard. The new BMW 535d sets new
standards also in terms of environmental compatibility, fulfilling the
demanding EU 4 emission limits with the help of a soot particle filter
featured as standard and operating with maximum efficiency throughout a
very long service life without the use of additives or any need for
maintenance. In standard trim the BMW 535d conveys the power of the
engine to the rear drive wheels via six-speed automatic transmission
with Steptronic. Just some of the signs of distinction setting the new
top-of-the-range diesel apart from the BMW 530d are 17-inch wheels with
225/50 R 17 tyres fitted as standard, a modified front air dam, as well
as larger, round exhaust tailpipes like on the BMW 545i. The new BMW
535d Saloon and 535d Touring are scheduled to enter the market in
September 2004. Prices will be announced in July. New
six-cylinder gasoline engine making its first appearance in the BMW 6
Series. Another great BMW tradition is now also being repeated:
Following the first BMW 6 Series launched in the late '70s with its
six-cylinder power unit, the new BMW 630i Coupé and Convertible
are now also making their debut with six cylinders. With the
six-cylinder BMW 6 Series always having been a very popular model, BMW
is now re-introducing this car in its model range: The new engine
displacing three litres is making its debut in both versions of the BMW
6 Series and will be introduced at a later point in time in other BMW
six-cylinder models. Displacing 2996 cc, the new six-cylinder develops
maximum output of 190 kW (258 bhp) at 6600 rpm, with maximum torque of
300 Newton-metres (221 lb-ft) at just 2500 rpm. With its compression
ratio of 10.7:1, the engine is able to run on unleaded 91-98 RON fuel.
Fuel consumption of the BMW 630i Coupé with its six-speed manual
gearbox averages just 9.0 litres on 100 kilometres (31.4 mpg Imp)
(six-speed automatic transmission: 9.5 litres/29.7 mpg Imp). Fuel
consumption of the BMW 630i Convertible, in turn, is 9.6 and,
respectively, 9.9 litres/100 km (29.4/28.5 mpg Imp). Compared with the
two versions of the BMW 645Ci, the transmission ratios of the manual
gearbox and automatic transmission are now a bit "shorter",
the customer opting for the BMW 630i naturally still having the choice
of a manual gearbox, BMW's Sequential Manual Gearbox (SMG), or
automatic transmission. With the driver shifting gears manually, the
new BMW 630i Coupé accelerates to 100 km/h in just 6.5 seconds
(automatic transmission: 6.7 seconds). The BMW 630 Convertible
completes the same exercise in 6.9 and, respectively, 7.2 seconds. Top
speed on all versions is 250 km/h or 155 mph. Low weight for supreme
performance. Depending on the transmission and body variant, the weight
of BMW's new 630i models is down on average by 120 kilos or 265 lb in
comparison with the 8-cylinder models. And the visible signs of
distinction setting the BMW 630i Coupé and Convertible aside
from the top models within the 6 Series are clearly recognisable both
inside and outside: The BMW 630i comes as standard on 7 1/2-inch wide
and 17-inch high light-alloy wheels in brand-new styling and with
245/50 R 17 tyres. The front brake discs, in turn, are somewhat smaller
in diameter than on the BMW 645Ci. Further differences from outside
are the chrome-plated exhaust tailpipes on the new BMW 630i
Coupé and Convertible now round instead of oval in shape, as well
as black instead of chrome-plated rods in the radiator grille in
typical BMW "kidney" design. Inside, the new six-cylinder
models come in an attractive combination of leather and fabric, with
all-leather upholstery available as an option at extra cost. Both of
these new models will be available in the German market as of September
2004. Their prices will be announced in July.
