Offering a tease for all those who can't attend its official debut at the upcoming Los Angeles Auto Show, Bentley has unveiled its beautiful Grand Convertible concept. Dubbed by the premium automaker to be the "ultimate expression of British automotive luxury" and the "most sophisticated open-top car ever created by Bentley," this concept offers an upscale cabin and exterior that more than fits the bill. Looking to be a convertible take on the Mulsanne, it offers a two-door, retractable soft top option with a stunning Sequin Blue exterior with "liquid metal" accents touching the hood and the windscreen. Inside, the lux treatment continues with diamond quilted leather seats, complementary Sequin Blue accent stitching, and a forest full of wood trim, including about an acre of wood veneer on the dash. Under the hood, a 6.75 liter V8 puts out 530 horses and 811 lb-ft of torque, essentially matching its beauty with brawn. See more preview shots after the jump, especially if you can't make it to the show as there's still no final word yet of it going to production.
