Bentley delivers powertrain with 40% improvement in fuel efficiency; new direct-injected V8 with cylinder deactivation
Bentley will unveil two new Bentley Continental V8 models at the Detroit Auto Show in January, both equipped with a new 4.0 liter, twin turbocharged V8 engine with cylinder deactivation. The new engine and a new close-ratio 8-speed transmission help meet Bentley’s commitment to a new powertrain delivering a 40% improvement in fuel efficiency and CO2 emissions.
The V8 delivers maximum power of 500 bhp (507 PS/373 kW) at 6000 rev/min and an peak torque of 660 N·m (487 lb-ft) available across the rev range from 1700 to 5000 rev/min. With the 8-speed automatic transmission, this translates into a sub-5 second acceleration time 0-60 mph (0-100 km/h) and a top speed of more than 180 mph (290km/h).
The new V8 Continental models are capable of travelling more than 500 miles (800km) on a single tank of fuel; full and official figures will be released in early 2012.
The new V8 engine features variable displacement (i.e., reduction from 8 to 4 cylinders under certain load conditions); high-pressure direct-injection; low friction bearings; thermal management, energy recuperation via the charging system; and turbocharger packaging for greater efficiency.
The two new V8 Continental models will be offered beneath the flagship 6.0 liter, 12-cylinder engined Continental GT and GTC.
