The Blower Bentley represented one of two solutions to a problem. In 1928, despite the fourcylinder
4 ½ Litre’s Le Mans win, the consensus at the Bentley works was that it was no longer competitive.
W.O. Bentley’s decision was to create the Speed Six. The other decision was to supercharge the four.
W.O. hated this latter idea. But Sir Henry Birkin, whose notion it was, had persuaded fellow
Bentley team driver Woolf Barnato that it was worth a try – and, since Barnato’s heavy investment in
Bentley Motors, Ltd. was the principal reason the company was still alive, W.O. had no recourse but to
grudgingly give his okay, and incidentally find room at his factory for production of the 50 cars necessary to
qualify for Le Mans. Fortunately, Birkin had also convinced the Hon. Dorothy Paget to finance premises at
Welwyn for the conversion of 4½ blown production cars into race cars – so W.O. did not have to witness the
final desecration which would, in his words, “pervert” his engine and “corrupt its performance.”
Actually, the performance of the Blower Bentley was spectacular – in short spurts. Blindingly fast,
the car was also woefully unreliable. A Speed Six won Le Mans in 1929 and 1930. The Blower never did
win a race. Its best finish was second in the 1930 French Grand Prix to a Bugatti that was half its weight.
This was a compelling achievement, but didn’t impress W.O. much. The Blower’s other moment of
competitive glory was at Brooklands in 1932 when Birkin broke the Outer Circuit record at 137.96 mph.
At $7375, the Blower Bentley was priced about $2000 more than an unsupercharged version. The
car on display, distinguished by its flared wings, cutaway sides and liberal use of chrome plating, was
originally ordered by the adventurous Miss N. McCaw. It was brought to this country in 1932 and was
owned for a time by the Packard Motor Car Company.
Given its competition record, the Blower Bentley might have been forgotten. But some cars achieve
mythic status through sheer audacity. Ian Fleming helped when he provided James Bond a Blower Bentley
to drive in his earlier novels. A secret agent behind the wheel of this conspicuous car? Fiction nicely

Briggs Cunningham was one of the first to use two-way radios at Le Mans in 1950 by installing them in both the LeMonstre and the Petit Pataud. You can see both cars at Revs. Learn more
