The combination of a diesel engine and BMW xDrive all-wheel drive, which will
also be found in the BMW 640d xDrive Convertible, gives the BMW 6 Series a
spread of abilities none of its rivals can match.
The new BMW 640d xDrive Coupe accelerates from 0 to 60 mph in just 5 seconds.
The 230 kW/313 hp diesel powerplant uses BMW TwinPower Turbo technology to
ensure outstanding efficiency, and joins forces with the standard-fitted
eight-speed Sports automatic gearbox to deliver exceptionally low fuel
consumption and emissions. The xDrive system distributes the power generated by
the engine precisely between the front and rear wheels as the situation demands.
Pulling the strings behind the scenes is an electronic control unit which links
xDrive up with the DSC (Dynamic Stability Control) system to ensure unbeatable
traction, maximum safety, top-class handling and optimum power development in
all weather and road conditions. The average fuel consumption of the BMW 640d
xDrive Coupe stands at 5.7 - 5.8 liters per 100 kilometers / 48.7 - 49.6 mpg imp
(in the EU test cycle, depending on the tire format), while CO2 emissions are
149 - 153 grams per kilometer.
Diesel Engine
The instantaneous responses and pulling power of the diesel unit fitted in the
BMW 6 Series enable it to do everything required of an engine fitted in a car
with a sharp sporting focus. The output characteristics, acoustic profile, low
vibrations and efficiency of the six-cylinder unit offer clear evidence of BMW's
expertise in the development of diesel engines.
Rewinding a generation, the introduction - for the first time - of a diesel
variant into the previous BMW 6 Series likewise lent an extra dimension to the
range. The new BMW 6 Series adds further luster to the alluring profile of the
exclusive and sporty, yet also economical, premium-class Coupe by taking
performance and efficiency to new heights and, for the first time, offering the
additional benefits of xDrive.
The latest generation of the most powerful diesel engine boasts displacement of
3.0 liters, a low-weight all-aluminum crankcase and the latest development of
BMW TwinPower Turbo technology. This package of technology comprises multi-stage
turbocharging and common-rail direct injection whose piezo injectors work with
maximum pressure of 2,000 bar. The car's two-stage turbocharging generates
instantaneous and forceful power delivery, while the injection system sprays the
fuel into the cylinders in precisely measured quantities to ensure clean and
efficient combustion.
