Bentley Continental GT3-R with 572 bhp V8 revealed

The Bentley Continental GT3-R arrives with a 572 bhp V8 As we reported last week, it looks like Bentley has decided to do a V8 take on the original Continental Supersports with the arrival of the Bentley Continental GT3-R, a lighter, more powerful Continental V8. Just like the original Continental Supersports, the Continental GT3-R loses its back seats and goes on a diet (down 100 kg on the V8S) and gets a retuned version of the 4.0 litre twin-turbo V8 producing 572 bhp and 516 lb/ft of torque together with shorter gearing to deliver a 0-60 mph in just 3.6 seconds (0-62mph in 3.8s). The GT3-R still comes with Bentley’s four wheel drive, but it gets torque vectoring too and a modified ESC and a chassis tuned for outright cornering ability to make the GT3-R Bentley’s most dynamic road car to date.
