A Single-Seat 4.5 Liter Supercharged "Blower" Race Car became the most expensive Bentley to ever cross the auction block when it sold yesterday for an astounding £4.5 million ($7.05 million).
The car, which was famously campaigned by Le Mans winner Sir Henry "Tim" Birkin, sold at an auction held as part of this weekend's Goodwood Festival of Speed in England.
In the late 1920s and early 1930s this car was a regular sight at the banked Outer Circuit at Brooklands. Amazingly in March of 1932 Birkin drove the supercharged 240 horsepower Bentley to 137.96mph—at the time a circuit record.
The Telegraph explains how Birkin described the surface of the Outer Circuit after the record setting run in the Bentley—
"There are bumps which jolt the driver up and down in his seat and make the car leave the road and travel through the air."
The previous record for most expensive Bentley sold at auction was held by a Speed Six from the 1920s which sold for £2.8 million in 2004.
