1951 Allard K2

When Sidney Allard fit the Cadillac V8 into his own J2 Roadster he created the first K2. That first car was immediately put into competition as a road-going version of the J2 race cars.

The K2 came standard with a Ford V8, but Chrysler, Mercury and Oldsmobile were also fitted. The model was introduced in 1950 and nearly 120 cars were produced over a two year period.

1951 Allard K2 Roadster 91K1804 – sold for $104,500

Strikingly finished in British Racing Green with a black interior, this original left-hand drive example is fitted with a large hood dome providing clearance for the massive carburetors, two low-cut “Brooklands” windscreens, a Le Mans-style hood strap and cast-aluminum “knock-off” wheels. The current owner acquired it in August 2006, with the K2 having already been restored, and it has been regularly exercised since then. When a Texan purchased it in 1980 from a California enthusiast, it was understood that this K2 had some past West Coast racing history. Equally suitable for shows and vintage racing events, this Allard K2 is a splendid example of Sidney Allard’s legendary Anglo-American hybrids with its unique styling and downright brutal performance.
