The K3 was a two-seat tourer produced by Allard between 1952 and 1953.

The new Allard K3 was generally offered with the buyer’s choice of engine and then engine mounts were then fitted to suit. Allard kept his unique split-axle independent front suspension and borrowed his De Dion rear axle used previously in the Allard J2.

The Allard K3's frame was totally new. Made with a pair of stacked chrome-moly tubes as side rails, heavily gusseted with steel plates, it was both lighter and stronger than the previous stamped-steel channel-section chassis from earlier Allard cars.

The bodywork was new as well now being a modern “envelope” type with integral rather than separate fenders. Inside was a bench seat that could accommodate three people in relative comfort. Though built on a wheelbase six inches shorter than the K2’s, the Allard K3 seemed bigger than it really was. Its main bulk was in width (tracks were 56.5 inches front, 58.5 inches rear) and weight (2580 pounds at the curb).

Ventilation with the top and windows up was totally inadequate, and with top up and windows down, the car couldn’t be driven more than 35 miles per hour without the top flapping in the wind. Allard had intended the K3 to be a sporting, fast, and comfortable tourer that could be sold in all countries, but it was apparent that it still needed much more development. Most Allard K3s went to the US, although two went to Mexico and Canada. Also, one each was delivered to Germany, Venezuela, Colombia, Guatemala, India, Belgium, and England.

For its day, the Allard K3 was reasonably well finished although it was not as good as cars from the volume manufacturers. Allard had discovered that what passed for good fit and finish in a competition car was a far cry from what was needed for a popular road car.

Total production was just 62.
