Reworked W12 with new Bosch EMS to power upcoming Flying Spur

Ahead of its global debut at the Geneva Motor Show next month, Bentley has leaked pictures of the all-new Flying Spur, the car maker’s most powerful four-door model ever.

At the heart of the next-generation Fly Spur is Bentley’s iconic W12 engine, but the 6-liter twin turbocharged, 48-valve unit has been modified and upgraded, now delivering 625ps at 6,000rpm and 800Nm of torque from only 2,000rpm. In addition to the new power output levels, the W12 has also undergone a complete engine management system upgrade to the latest Bosch ME17 interface. Improved torque management, turbocharger control, drivability and emissions performance all result from the adoption and optimization of the new system.

Coupled to the reworked W12 in the new Flying Spur is the very latest eight-speed, quick-shift automatic transmission from ZF that delivers seamless shifts in under 200 milliseconds. An optimized set of gear ratios keeps the engine in its most efficient operating range under light loads and when cruising, contributing to an overall improvement in fuel consumption and CO2 emissions of more than 13% over the outgoing model. The new Flying Spur delivers a combined cycle fuel economy of 14.7l/100km (19.2mpg) and CO2 emissions of 343 g/km.

The transmission feeds power to all four wheels via Bentley’s all-wheel drive system. With a standard torque split of 60% to the rear wheels and 40% to the front, but the ability to vary this division up to 85% to the rear axle or 65% to the front depending on available traction, the Flying Spur’s drivetrain ensures optimal grip regardless of prevailing road or weather conditions, says Bentley.

The luxury car maker’s chairman and CEO, Dr Wolfgang Schreiber, added: “Our new Flying Spur is the ultimate luxury performance sedan. Our engineers have worked tirelessly to ensure that the Flying Spur is the perfect combination of power, comfort, refinement and hand-crafted quality. Fitted with the very latest technology, the new Flying Spur is equipped both for business and relaxation whilst remaining a car to enjoy from behind the wheel.”
