The Mulsanne's body cloaks an entirely new chassis for a Bentley. It consists of double wishbones at the front and a multi-link system at the rear. The body is suspended via an adaptable air suspension system that allows the car to lower its ride height at speed and maintain good body control and level suspension irrespective of load.
The Mulsanne’s powertrain is a totally refreshed version of Bentley’s 6.75-litre twin-turbocharged V8, now producing 505bhp and 752lb ft of torque. Other engines were considered, Bentley says, but dismissed because they wouldn’t produce the effortless low-rev torque that owners of grand Bentleys expect.
However, the technical update includes variable phasing of the single camshaft, cylinder deactivation to make it a V4 under light load, and lightweight pistons, conrods and crankshaft. It's a direct descendant of the original Rolls-Royce Bentley V8 of 1959, but today's engine could idle on the old one's unburnt exhaust hydrocarbons alone.
The engine is partnered with the very latest eight-speed automatic gearbox from specialist ZF. Its use means Bentley’s flagship model has gone from four forward speeds (in the old Arnage Red Label) to twice that number in less than a decade.
