Bentley Continental GT V8 S and GTC V8 S
Bentley engineers have managed to squeeze a bit more power out of the 4.0-liter twin-turbo V8 engine, bringing the horsepower rating from 500 up to 521.
The V8 S will make the sprint to 60 mph in just 4.3 seconds, and run up to a still-subsonic 192 mph. And the V8 S will still be able to go 500 miles between fill ups. The engine now produces 502 lb-ft of torque, though fuel economy figures, amazingly, have stayed the same.
