Tuner has a new aerodynamic kit for the Bentley Continental GT and is promising a power boost up to 660 HP.

Luxury tuner Onyx has a new GTO kit for the Bentley Continental GT for the rich Irishman who doesn't want to buy something completely British.

The GTO kit's aerodynamic package includes a new front bumper with carbon inserts, LED daytime running lights and a lower front splitter also out of carbon fiber. At sides are widening arches over the wheel wells and new side skirts. At the back is a revised bumper and rear carbon diffuser. Topping things off, literally, is a carbon fiber boot lid spoiler.

The Irish tuner is promising a power boost too on the Continental GT, up to around the 660 bhp (492 kW / 669 PS) from the series' 550 bhp (410 kW / 558 PS). Suspension lowering and new 22-inch black forged wheels are also part of the package.

Money continues to be thrown around on the inside, with a bespoke buffalo hide leather finish coupled to carbon trims for the interior panelling.
