The speediest Bentley ever just got a bit speedier. A power boost for the top-dog Continental GT Speed adds 7 horsepower and 13 lb-ft of torque to the car’s monstrous twin-turbo W-12 engine, bringing totals to an impressive 633 hp and 620 lb-ft. There’a also a new Black Edition model for the Continental GT Speed that gains, as you’d expect, a array of contrasting dark trim.
The extra grunt from the 6.0-liter W-12 comes from more turbo boost across the rev range, and the increased torque peak is still delivered between 2000 and 5000 rpm. (We’ll have to wait until the next-gen Continental GT to see Bentley’s all-new W-12 engine in this car.)  The claimed 0-to-60-mph acceleration time drops down by a tenth to 3.9 seconds, while the Speed’s top speed remains at 206 mph?still pretty darn fast for a 2.5-plus-ton beast. As before, power is routed through an eight-speed automatic and an all-wheel-drive system.
The Continental GT Speed also is jumping into the ever-expanding blacked-out special-edition pool with the creatively named Black Edition. It gains numerous pieces of contrasting dark exterior trim, including the window surrounds, lighting bezels, and 21-inch wheels, while customers can choose one of four contrasting hues to for the front splitter, side skirts, and rear diffuser. On the inside, carbon-fiber trim is everywhere and contrasting leather inserts for the seats match the exterior trim accents.
