Beyond its connection to Rolls-Royce, Bentley cars these days are known for luxurious and posh motoring. However, the company's century-old history came with performance machines as well, most notably so in the 1920s when it headlined the 24 Hours of Le Mans for several years.

With nearly a hundred years since Bentley first started making performance vehicles, the evolution should have been massive but how much exactly? In this drag race, courtesy of the UK's Carwow, four significant performance models with Bentley badges lined up for what appears to be the most expensive drag race ever.

And that's because of the oldest contender in the straight-line contest – the Blower Bentley, which is 93 years old and valued at £20 million. It's powered by a Roots-type supercharged four-banger making 240 bhp and 258 lb-ft of torque. Of note, Bentley sold 12 continuation specials of the Blower in 2019.

Second to the oldest here is the Bentley Turbo R. It's powered by a turbocharged 6.8-litre V8 that's good for 302 bhp and 487 lb-ft of torque, tipping the scales at 2,450 kg.

The more modern Bentley performance models are led by the Continental R, powered by a turbocharged 6.75-litre V8. It churns out 420 bhp and 649 lb-ft of torque but is a bit porky at 2,400 kg.

And of course, the latest Bentley Continental GT Speed, which boasts a massive twin-turbo 6.0-litre W12 engine that puts down 659 bhp and 664 lb-ft of twists. It weighs 2,200 kg.

The more modern Continental GT Speed will definitely win this contest but how far was it compared to the older generations of Bentley performance models? The video above should answer that for you.
