Bentley has released new details about the Mulsanne's 6.75-liter twin-turbo V8 engine.

Taking nearly 30 hours to build, the engine features over 300 new (or significantly re-engineered) components to ensure it is more powerful and fuel efficient than its predecessor.

In terms of performance, the V8 produces 505 bhp (377 kW / 512 PS) and 1020 Nm (752 lb-ft) of torque. This enables the Mulsanne to rocket from 0-60 mph in 5.1 seconds (0-100 km/h in 5.3 seconds), before hitting a top speed of 184 mph (296 km/h).

While this is pretty impressive for a car with a 2585 kg (5700 lb) curb weight, Bentley paid special attention to being eco-friendly. Due in large part to two new control systems, cam phasing and variable displacement, the engine has a 15 percent improvement in emissions and fuel consumption. Despite this, the Muslanne has a combined fuel consumption rating of 16.7 mpg UK (16.9 liters/100km).

Once the engines are completed, they are put on state-of-the-art balancing machines to rigorously test all the spinning components. Once they pass inspection, the engines are put through an 80-minute test cycle where engineers run the V8 from idle to maximum revs to simulate real-world driving conditions.
