The 610-hp Bentley Continental GT Speed wasn’t powerful enough for edo competition. Even the top speed of 203 mph wasn’t satisfying to the tuning firm. So edo took the 6.0L W12 added a high-performance exhaust system along with the ECU recalibration and increased output to a total of 680-hp with a maximum torque of 649 lb-ft.

0 to 62 mph now comes in just 4.2 seconds with an eye-watering top speed of 211 mph. Performance is enhanced by dropping the suspension by a maximum of 35 millimeters.

edo didn’t add many visual modifications but transferring all that power to the ground are 20-inch wheels wrapped in Contact V-Max tires.

Hamann, a well known German tuner, is famous for offering some outstanding tuning packages for Porsche, Lamborghini and BMW vehicles. Recently Hamann has also branched off into the Mercedes-Benz and Aston Martin territories with Bentley to join the ranks very soon.

Hamann has dropped the first official images of its take on the Bentley Continental GT and GT Speed. Official technical specs and other details are yet to be released but you can expect Hamann will do a lot with the stock 600-hp W12 under the hood.

From the images you can see that Hamann will offer a very aggressive body kit that gives the Continental GT and GT Speed a more muscular stance with an upgraded red-leather interior.
