Bentley has just now unveiled its fastest production car ever, the latest version of the Continental GT Speed. Boasting a top speed of 331kph, the updated GT Speed’s 6.0-litre W12 engine now makes 633bhp, up from 626bhp, and 840Nm of torque, up 20Nm. The 0-100kph dash is despatched in 4.1 seconds thanks to that massive twist distributed across a wider rev band, from 2,000rpm to 5,000rpm.

Along with the revised model, Crewe has also introduced a Continental GT Speed Black Edition that adds several visual elements such as high gloss black finish for the exterior trim including window frames and lamp bezels, 21in five-spoke alloy wheels, and special brake callipers available in either red or black.

Inside, the Black Edition’s dashboard, as well as centre and roof consoles get carbon fibre accents while the upholstery is done in contrasting leather, available in Porpoise, Beluga, Pillar Box Red or new Cyber Yellow to match the exterior styling trims. And of course, there’s diamond quilting on the doors and Mulliner GT Design seats. “We have developed the GT Speed Black Edition to meet demand from customers for a model in the Continental line that offers both increased sporting capabilities and instantly recognisable styling cues,” says Paul Jones, product line director for the Continental GT. It’s available in both coupé and convertible form.

According to Bentley, each of the revised Continental GT Speed models will take 110 hours to handcraft, while the W12 engine is assembled by 30 engineers over 12 and a half hours. Order books have opened for the new GT Speed and the GT Speed Black edition, with deliveries set to start later this year.
