Austin-Healey 100M Le Mans Roadster

In late 1955, three years after Donald Healey unveiled his “Hundred,” the 100M made its debut. Modified with the racing experience gained from Bonneville to Le Mans, the 100M received a high-lift camshaft, larger carburettors, higher-compression pistons, free-flowing intake manifold, cold air box and a special distributor. Output increased from 90 to 110 hp, and the suspension received larger anti-roll bars, while a Le Mans-specification leather strap retained the louvered bonnet. Even the later six-cylinder models did not exceed the resulting performance enhancement, and when production ended in July 1956, just 640 examples of the 100M were built.

As confirmed by the 100M “Le Mans” Registry and the British Motor Industry Heritage Trust, this genuine factory-built 100M is a late-production left-hand drive export model, which was completed on 18th April 1956 and delivered to a dealer in Düsseldorf. In addition to its Le Mans-specific upgrades, this 100M included such factory-fitted equipment as a speedometer calibrated in mph, wire wheels, a laminated windscreen, a heater and dual “vertical dip” headlamps.

This car was auctioned off by RM Auctions in May of 2010 at the Grimaldi Forum, Monaco, in August of 2010 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California, in January of 2011 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona and in March of 2011 at the Ritz-Carlton, Amelia Island, Florida.
