Each Arnage is largely hand-built. It comes in three models: the base R, high-performance T, and RL limousine. The RL limousine has an extended 9.8-inch wheelbase to provide more passenger room. Inside, the cabin is trimmed in quality wood materials such as walnut, oak, bird's-eye maple or black lacquer. The R trim is powered by a 400 hp twin-turbocharged 6.8-liter V-8 that is mated to a four-speed automatic transmission. The T trim boosts the engine power to 450 hp.The Bentley Arnage is a carryover from 2005.
