A Big American V-8 In Sexy English Bodywork


Killer performance, incredible handling, futuristic styling; that’s a brief description of the 1951 Cad-Allard. These incredible sports and touring cars arrived on our shores through the courtesy of Sidney Allard, a British entrepreneur who made his living building low-volume British rally cars. His passion and racing successes led him to up the ante in performance with the development of Allards like the sporty J2 and this month’s cover car, the elegant K2.

Produced at his factory outside of London from July 1949 through early 1951, the J2 was built for one reason only, and that was to win races. The sleek, two-seat roadster rode on a short, 100-inch wheelbase. A modified Ford flathead V-8 powered early cars. While the flathead was a decent performer in the 1,700-pound J2, the engine design limited its potential as a high-powered sports car.

The touring-friendly K2 got a longer 106-inch wheelbase and was a full 168 inches long. This added a few more pounds, with the beautiful K2 tipping the scales around 2,400.

Sidney Allard used small, 200-odd-cube flatheads, but he also kept abreast of the new OHV engines available in America, and recognized the need to update his powertrains.

One of the engines Allard used was the 331 cubic-inch Cadillac mill, as seen in the K2 in these photos. This high-tech powertrain offered 40 more horsepower than the modified flathead. But unlike vehicles ordered with the factory-installed flathead, Allards ordered for delivery in America with an OHV engine were shipped without powertrains. Allard distributors would do the installation for the customer.

Few sports cars of the time provided were as complete a package as the J2. The chassis consisted of open channel outer sections and four tubular crossmembers that proved to be extremely strong and free of flex. With the engine set back, more than 50 percent of its weight was positioned over the rear wheels. It was like driving a high-powered go-cart.

Their aluminum bodies were sleek, with aggressive front and rear fenders and a large bulge protruding on top of the hood to accommodate the Cadillac mill. A soft convertible roof was standard equipment but no side curtains were available, making it a tough car to drive in inclement weather. The very small trunk had enough space for a spare tire but little more. After all, this was a race car not a luxury car.

Other than the OHV powertrain, most mechanical components were of Ford decent. Allard was at the time one of the largest Ford distributors in England, and because of that he had the ability to procure parts at reasonable prices. He also knew that Ford parts were available worldwide, which limited his company from keeping a facility of specialty parts on hand for service.

The unique split beam, swing arm, independent front suspension consisted of a modified Ford I beam axle that was cut in two and pivoted at the inner ends. Coil springs moved the I beams vertically. The steering system provided fast cornering, turning lock to lock in 2.5 turns of the wheel. The rear suspension was radical for its time, yet it was made primarily of vintage Ford parts. Allard designed a low-cost version of a deDion axle assembly that allowed the rear wheels to travel up and down, while keeping the wheels vertical at all times. As with the front, coil springs were used.

Allard focused on providing a total performance vehicle that not only accelerated but also stopped well. Disc brakes weren’t on the horizon yet, but Allard installed 12-inch drum brakes all around to make braking a non-fade event unless pushed extremely hard.

Front drum brakes were cooled through air scoops designed into the body, and aluminum fins were bonded into the cast drum surface to help conduct heat to the outside air.

As is the case with such timeless classics, very few were ever manufactured during their short runs: 90 J2s and 119 K2s. In its heyday, the Cad-Allard positioned itself as the epitome of road-racing and grand-touring machines. Today, these very rare icons are loved and admired by sports car enthusiasts worldwide.

Engine – The Cadillac powertrain provided exhilarating performance, yet high-speed runs were limited by lifter float.

Handling – The Allards’ handling was perhaps one of the best attributes of the cars. With great weight distribution and a unique front and rear suspension, the Allards were among the best handling cars in America.

This Allard’s value and rarity is simply too high to use as a driver. Perhaps a few owners might take their Allards out once in awhile, but most cars are taken to shows locked safely away until the car reaches its destination. There is a small group that continues to race vintage Allards.
