The new Mulsanne Speed is tailored for the driver, with 537 PS (530 bhp / 395 kW), 1,100 Nm (811 lb.ft) and selectable sports suspension and steering on demand.

The reengineered powertrain, featuring Bentley's mighty 6¾-litre twin-turbo V8, propels the Mulsanne Speed to 60 mph in 4.8 seconds (0-100 km/h in 4.9 seconds) and on to a top speed of 190 mph (305 km/h). In modern Bentley tradition, the extra performance is matched by markedly improved efficiency; a 13% gain means a range extended by 50 miles (80 km).

New and contemporary styling features define the Mulsanne Speed as a statement in quintessential British luxury. On-board technology and connectivity are discreetly integrated beneath the finest materials, created with unrivalled craftsmanship and exquisite handcrafted details.

Chairman and Chief Executive of Bentley Motors, Wolfgang Dürheimer, comments:

"The new Mulsanne Speed is the car that defines Bentley, as a flagship for driving luxury performance. Our customers don't compromise, and we've adopted the same approach in the design, engineering and crafting of our new flagship. The Mulsanne Speed is distinguished, calm and relaxing, but always with a connection to the road and relentless dynamic performance on demand. In this car, every journey becomes a drive."

The Mulsanne Speed will be unveiled at the Paris Motor Show on Thursday 2nd October, and will be available for customer delivery this winter.

At the heart of the Mulsanne Speed is Bentley's iconic 6¾-litre twin-turbo V8 engine, which has been re-engineered for the Mulsanne Speed as well as the signature Mulsanne. A totally redesigned combustion system (including combustion chamber, inlet ports, fuel injectors, spark plugs, and compression ratio) promotes a much faster and more controlled combustion process. Through combining these advances with new variable valve timing and optimised turbocharger control, torque output of the engine has been pushed to record levels - 1,100 Nm (811 lb.ft) from 1,750 rpm.

The swell of torque from low engine speeds builds to a new peak power output of 537 PS, enough to drive the Mulsanne Speed to a top speed of 190 mph (305 km/h) - an unrivalled figure in the ultra-luxury sector. The 0-60 mph sprint is covered in 4.8 seconds, with 0-100 km/h taking just 4.9 seconds.

The new engine is paired with a recalibrated gearbox designed to enhance the driving experience of the Mulsanne Speed. The gear strategy is optimised for the new, higher wave of torque, and is designed for instant torque delivery on throttle application. The connection between the car and driver has been the focus, and extensive validation with both keen drivers and professional chauffeurs has proven the new setup. A new "S" mode gives the driver even more control, and maintains the engine speed above 2,000 rpm so that the turbochargers are always ready to deliver instantaneous performance.

An extensive recalibration of the engine management system has yielded benefits beyond increased torque and power. The cylinder deactivation system, that runs the engine as a V4 during light load, has been retuned for smoother transitions between V8 and V4 for even greater refinement. This work combines with a new gearbox control strategy and the engine hardware improvements to give a new level of efficiency for the Mulsanne engine.

Meeting the new EU6 emissions legislation, and designed to also meet the upcoming US LEV III standards in the future, the new powertrain records 342 g/km of CO2 on the NEDC drive cycle - a 13% improvement on the current Mulsanne. The ensuing fuel economy improvements have extended the fuel range of the new Mulsanne Speed by 50 miles (80 km).

To deploy the effortless power and acceleration on offer in the Mulsanne Speed, an even more driver-focused Sport suspension mode is included. While the Bentley and Comfort suspension modes provide a comfort-focused and fully compliant chassis setup, the Sport mode stiffens the all-round air suspension for improved body control and adjusts the steering dynamics for greater feedback and accuracy. The driver can also choose to individually match steering, chassis and engine tunes according to personal preference through the Custom setting.

Through this new setup, the Mulsanne Speed builds on the abilities of the signature Mulsanne model, being able to switch from a communicative and enjoyable car to drive at pace, to a relaxing, comfortable and exceptionally refined limousine.
