And so for 2015 the Bentley Continental GT Speed and Bentley Continental GT Speed Convertible will receive a slight bump up in power, and will now offer 626-hp and 607 lb-ft of torque.

Performance from 0-62mph is just 2.6 seconds (2.8 seconds without the Weissach Package), 124mph is reached in 7.2 seconds (0.5s quicker) and 186mph in 19.9 seconds (2.1 s quicker).
