Key to this performance increase is the most powerful version of Bentley's legendary V8 engine ever built at the company's headquarters in Crewe, England. In the performance-oriented Arnage T model, the revised twin-turbocharged V8 engine produces a staggering 500bhp and 1000Nm of torque – an 11percent increase in power and a 14 percent increase in torque over the outgoing model. Twinned with the latest six-speed ZF automatic transmission, which uses state-of-the-art computer management, performance and refinement are optimised at all speeds. In the Arnage R and RL models the new engine is boosted from 400 to 450bhp, while torque climbs from 835 to 875Nm.
