Bentley is celebrating the W12 engine that has powered its performance flagships and the brand since 2003 with the limited-edition Speed Edition 12. Based on the Speed specification Bentayga, Flying Spur, Continental GT and Continental GT Convertible, the Edition 12 package features many unique design enhancements. These include Edition 12 badging, numbered engine plaque, Edition 12 embroidery, colour graduated seat contrast stitching, and a fascia in Grand Black veneer with the engine firing sequence etched alongside an inlaid Edition 12 badge.

Speed Edition 12 exterior

The external features of the Speed Edition 12 models are subtle yet carefully curated, making it instantly recognisable to those in the know. Among the distinctive details are silver brake callipers, which are not available for any other Bentley model. Continental GT and Convertible models feature Speed Edition 12 badging on the front fender while Bentayga and Flying Spur models carry Edition 12 badges on the rear quarter together with the existing Speed badge. Opening the bonnet reveals a numbered Edition 12 plaque in pride of place on the engine’s cover.

Other exterior features include Blackline specification exterior brightware, 22-inch black painted Speed alloy wheels, and self-levelling wheel badges. A new paint colour, Opalite, is available as an option: a light grey-green, it has a subtle copper effect that glows in bright sunshine.

Speed Edition 12 interior

Edition 12 welcome lamps and illuminated treadplates greet driver and passengers to an interior of hand-crafted individuality. All Edition 12 models are available with Bentley’s Speed colour splits; the main colour, Beluga black can either be chosen as the sole upholstery colour or complemented by Brunel blue, Cricketball red, Linen or Orange. Veneer in each case is high gloss Grand Black.

Unique features of this limited edition include seats with Mulliner Silver piping and embroidered Edition 12 namestyle. The upper seat areas are quilted, and contrast stitched in a graduated three-colour ‘fade’ from Anthracite through Porpoise to Stratos. Quilted door panels are contrast stitched.

The organ stop air vents are also unique, featuring the numeral ’12’ machined from solid on the face of the control. As another delightful detail, the Grand Black veneer facia facing the front seat passenger features the firing sequence of the W12 engine etched alongside an inlaid Speed Edition 12 badge.

W12 swan song

In 2003, Bentley’s W12 engine heralded a new era for the company as the powertrain for the first all-new model under Volkswagen Group ownership, the Continental GT. The unique W-formation of the 6.0-litre twin-turbocharged W12 enabled it to be 24 per cent shorter than an equivalent V12 with no compromise in power, efficiency, or refinement. Ever since, continuous evolution has seen a 37 per cent increase in power and a 54 per cent increase in torque, along with a 25 per cent reduction in emissions. In the Speed Edition 12 models, the W12 now develops up to 659PS (485kW) at 5000-6000 rpm, while the famed Bentley ‘tidal wave’ of torque sees a peak of 900Nm reached at just 1500rpm and continuing unabated through to 5000 rpm.

In a bid to ensure that the Speed Edition 12 becomes a rare and sought-after tribute to an engine that has powered the company’s cars – and its fortunes for two decades – only 120 of each of four models will be produced.
