Bentley has shown sketches of a Mulsanne Convertible. Officially it is only a concept, but no-one doubts there will be such a car.

Bentley is not exactly going for British understatement, calling it "the world's most elegant and sophisticated convertible." Possibly they were a bit upset by the prominent presence of the Rolls Royce Phantom Drophead at the closing ceremony of the Olympics.

The interior is said to be inspired by luxurious, high-performance power boats, and is intended to offer a combination of space and intimacy. Bentley says, "The Mulsanne Convertible Concept reinforces Bentley's position as the undisputed benchmark in handcrafted automotive luxury." Who can that comment be aimed at?

However, it is certainly true that, whoever is considered to be at the pinnacle of automotive luxury, the cars come from British factories. Since Maybach is in the process of being put down by its embarrassed owner (Mercedes-Benz), Rolls-Royce and Bentley are the only credible purveyors of super-luxury saloons and convertibles. Given the steady increase in the numbers of the ultra-wealthy over the last decade, that is not a bad place to be.

We applaud anything that helps British exports, but we can't help smiling on the fawning way in which companies have to address super-rich clients. The company says the new car will appeal, "to automotive connoisseurs seeking the ultimate in contemporary design, prestige and exclusivity" We never knew rap stars were so discerning.
