- Desirable 'Speed' Example - Legendary Twin-Turbocharged W12 Engine - Including All Seasons Specification - Full Bentley Service History - UK Supplied The GT Speed Convertible combines the sensory pleasures of roof down luxury with the incredible performance of a 626 bhp twin-turbocharged 6.0 Litre W12, while seeing an improvement over the previous model in CO2 emissions thanks to a new engine management system and a quick shifting eight speed transmission. From the outside, the Continental GT Speed Convertible has a redesigned front bumper, lower grille, fender and a wider rear bumper. The lean muscular form of the rear haunch and the Bentley matrix grille provides a clear reminder of the car's racing heritage. The 21" Speed alloys are unique to this model and they accentuate the wide, low and poised stance. The car features uprated 10mm lowered suspension and retuned steering provides sharp communicative handling without detriment to the renowned ride comfort. The four-layer hood ensures high levels of refinement and acoustic insulation. Inside, exclusive treadplates featuring the 'Speed' legend welcome you to a four-seat cabin that features the hand-craftsmanship of the Mulliner Driving Specification, with its diamond quilted hide upholstery. Set into the fascia, sits the re-designed dashboard-mounted clock, alongside instrument dials with chrome bezels that match the bulls-eye air vents and knurled chrome organ stop controls. The infotainment system features Bentley's software upgrades, which vary from region to region but include refinements such as point of interest mapping and live traffic data. The Bentley Continental GT Speed Convertible really is one of the greatest in luxurious convertible driving machines.
