Bentley Mulsanne Speed revealed

Bentley has revealed a sport sedan version of its flagship Mulsanne. Dubbed Mulsanne Speed, the company is billing it as “the fastest ultra-luxury driving experience in the world”.

The Mulsanne Speed gets a more potent 6.75-litre V8 engine, bespoke styling inside and out, and chassis changes aimed at providing a more focused drive. It will reach international markets later this year, after a debut at the Paris motor show in October.

Powering the Mulsanne Speed is a re-engineered version of the firm’s twin-turbo V8. The combustion system has been redesigned, while new variable valve timing and turbocharger controls help swell the power output to 530bhp and torque to 112kgm at 1750rpm, up from 505bhp and 104kgm in the Mulsanne. This engine helps shift the Mulsanne Speed from zero to 100kph in just 4.9 seconds and on to a top speed of 306kph. Cylinder deactivation features on the engine, allowing it to run as a V4 on light loads.

The eight-speed automatic gearbox has been recalibrated to improve torque delivery and the connection between car and driver. It also includes a new ‘S’ mode, which keeps the engine speed above 2000rpm to allow quicker turbo response. A new Sport driving mode is offered in addition to the existing Bentley and Comfort modes. This new setting stiffens the air suspension and adjusts the steering “for greater feedback and accuracy”, says Bentley.

Visually, the Mulsanne Speed is differentiated from the standard Mulsanne, on which it is based, by a new dark tint to the stainless steel front grille, front mesh, front headlights and rear lights. It is equipped with 21-inch alloy wheels, which are ‘handed’, so there are bespoke designs for the alloys on both sides of the car. Twin exhaust pipes also feature and four new bodywork colours are offered.

New trims, colours and veneers are available for the interior, which as standard has the Mulliner Driving Specification option on the base Mulsanne. This includes diamond quilting for the seats and door panels, special pedals and a new headlining.

The Mulsanne Speed joins a revised version of the standard Mulsanne in Bentley’s range. The 6.75-litre V8 retains its 505bhp and 104kgm outputs, but fuel economy has improved by 13 percent. The eight-speed automatic gearbox has also been recalibrated for smoother shifts.

The styling is unchanged, but the new paint colours, hides and veneers offered on the Speed are also available on the standard Mulsanne.
