Bentley Motors is bringing two of its iconic supercharged 'Blower' models to this year's Mille Miglia.

Ettore Bugatti famously derided them as being the fastest trucks in the world, but snide comments couldn’t stop the rumbling racing cars from Bentley Motors from collecting countless wins and trophies in the 1920s.

One of the most famous cars from the British automaker’s early days is, ironically, also one of the company’s least successful models in terms of racing glory. By the time the supercharged ‘Blower’ Bentleys hit the track, the team’s glory days were quickly fading.

Against the odds, Bentley Motors racing cars had scored overall victory at the 24 Hours of Le Mans in 1925, followed by a stretch of four wins in a row from 1927 to 1930. Known for their robust build quality, and piloted by the brave ‘Bentley Boys’ racing squad, this early success cemented the brand’s legend.

The supercharged ‘Blower’ models were an attempt to quickly boost horsepower and keep the team competitive against the likes of Bugatti and Alfa Romeo. While they didn’t rack up as many wins, the Blower Bentleys are some of the most coveted classic cars in the world.

Two years ago, a 4.5-liter Blower Bentley sold for approximately $8.5 million at auction.

Bentley is bringing a 1930 Blower Bentley once owned by Sir Henry ‘Tim’ Birkin, one of the most famous of the Bentley Boys. The other was formerly a company demonstration car, which explains the car’s relatively roomy Vanden Plas Open, Sports Four Seater bodywork.
