BENTLEY is to create a range of special edition models to mark the end of its legendary W12 engine.

The Speed Edition 12 cars will be available on the Bentaygay, Continental GT and GTC and the Flying Spur.

Only 120 of each will be produced with the cars having special badging, treadplates, seat emrodiery, facia inlays and a numbered engine plaque.

And to celebrate the iconic engine - production of which will end In April 2024 - owners will receive a commemorative 15 per cent scale W12 engine block.

All the cars are based on the Speed specification of each model and the trim inlays include a graphical representation of the firing sequence of the W12 engine.

The W12 engine heralded a new era for Bentley 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.

Continuous evolution of the block 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 will develops up to 650 bhp while the famed Bentley ‘tidal wave' of torque sees a peak of 900Nm reached at just 1,500rpm and continuing unabated through to 5,000 rpm.

Among the distinctive details of the Speed Edition 12 models 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 bumper 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 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 which is a light grey-green with a subtle copper effect that glows in bright sunshine.

The scale model W12 engines are cast using aluminium taken from a full-size W12 engine block and will serve as a permanent memento of one of Bentley's most powerful engines.
