The coupé is a four-seater convertible developed from the 2005 model year Arnage.
It will be the fourth new model to go on sale in four years at Bentley since it became part of the Volkswagen Group in 1998.
The car is powered by a 450bhp version of the Arnage’s 6.75-litre twin-turbocharged, intercooled, V8 engine and produces 875Nm (645lb-ft) of torque. The folding roof on the convertible is operated hydraulically at the touch of a switch and the three-layer canvas roof is stowed beneath the rear parcel shelf in under 30 seconds.
Further details, including full technical specification, market availability and pricing, will be released nearer the Arnage Drophead Coupé’s on-sale date.
