Which British luxury car brand uses a winged 'B' logo?

The British luxury car brand that uses a winged “B” logo is Bentley.

Bentley’s emblem places the letter B inside a pair of wings, a design commonly known as the Winged B or Flying B. The wings evoke speed, aviation and freedom, while the central initial identifies the marque. It has appeared in variations on Bentley grilles, badges and radiator mascots for more than a century.

Bentley Motors was founded in 1919 by Walter Owen Bentley, better known as W. O. Bentley. The company first became famous for powerful racing and grand-touring cars, including its victories at the 24 Hours of Le Mans during the 1920s. That sporting history helped make the winged emblem a symbol of performance as well as luxury.

The logo is easy to confuse with Aston Martin’s winged badge, but the central letter distinguishes them: Bentley uses a prominent B, whereas Aston Martin’s emblem spells out the brand name. Rolls-Royce is identified instead by its Spirit of Ecstasy mascot and double-R monogram.
