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.

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.
Strikingly finished in red and fitted with beige leather upholstery, this 1951 Allard K2 has been fully restored. It retains the original, racing-specification 1951 Oldsmobile V-8 engine, which was bored to 330 cubic inches and fitted with an Edmunds dual two-barrel intake manifold. In addition, the transmission is the original Allard-installed circa-1950 Mercury unit, with overdrive. Among its many desirable features, other highlights include a set of chrome “knock off” wire wheels, Brooklands-type windscreens, a tachometer and a “banjo” steering wheel. Suitable for shows or vintage race outings, this Allard K2 is a splendid example of Sidney Allard’s legendary Anglo-American hybrids, with unique styling and fearsome performance.
