BMW Launches Powerful New Diesel

For the first time, BMW has combined its twin-turbocharged, six-cylinder diesel with the brand’s flagship Grand Tourer in the form of the new 635d.

The 635d Coupé and Convertible will hit showrooms in October in the UK with world’s most powerful production diesel under the bonnet. The revamp includes the 6 Series model line-up to include Active Headrests, Brake Energy Regeneration and other fuel saving and emissions-cutting technology.

A zero to 62mph time of 6.3 seconds is achieved by the BMW 635d Coupé, while the Convertible achieves this in 6.6 seconds. The new 635d has also been given a fine restyling to mark the technological changes: a revised headlight arrangement featuring LED technology and clear lenses, a new style of front valance and repositioned vertical struts on the front spoiler. It’s an output of 286hp and 580Nm of torque and is powered by a twin-turbocharged 2,993cc engine with an all aluminum crankcase and third generation common rail fuel injection system. The unique way the twin turbochargers work makes these performance figures possible. A smaller turbocharger yields near immediate response for swift initial acceleration before a larger turbocharger comes in mid-range to provide additional thrust through to the red line. Form just 1,750 rpm peak torque’s available to deliver a seamless wave of smooth acceleration.

The introduction of Efficient Dynamics, which is a technology with Brake Energy Regeneration, and the implementation of various needs-only operations of ancillary units for the first time in the 6 Series range make the performance possible.

The top of the range 650i models are has a 4,799cc V8 engine giving an output of 367hp. The models with their aluminum engine and double-VANOS and VALVETRONIC variable valve technology can do a zero to 62mph time of 5.1 seconds in the Coupé and 5.5 seconds in the Convertible.

Both 650i models are EfficientDynamics technology assisted in achieving improved economy and emissions figures.

The 630i and 650i has standard six-speed manual gearbox, while the 635d is a new six-speed sports automatic transmission. A new torque converter with enhanced software and a two-stage damper to eliminate vibrations are featured in this gearbox.

The new models also have a kidney grille that is larger compared to the outgoing model and lower reflectors that have been optically refined at the rear of a redesigned bumper. A third high level brake light now sits on the boot lid lip for enhanced safety. Another exterior change is the new alloy wheel design in 17-, 18- and 19-inch sizes.

SunReflective Technology leather is also offered among 6 Series Convertible models, which also have an infotainment system that includes eight favorite buttons.

As regards safety, BMW, for the first time, Active Headrests appear on the 6 Series. As standard equipment on cars, the system is introduced to prevent occupants from whiplash injuries in rear end accidents. Pyrotechnics fire to release two springs in the head rests when the airbags’ central control unit registers a rear end collision.
