[6] Since 1981, replicas of the later J2X have been manufactured by a succession of companies in Canada, whilst a continuation of the original models is also now being produced in the UK.

[6] This proved to be very successful, and the use of American components made it very easy to find parts for Allard's customers.

This did a few things beside improving the weight distribution: it gave the driver more leg room, and also facilitated easy identification between the two models J2 and J2X ("X" for extended).

Allard quickly developed new, barchetta-style bodywork to meet the regulations and called the resulting car the J2X Le Mans.

Manufacturing Company Limited, characterized their effort as a revival rather than a recreation, although a number of changes were carried out compared to the original design.

The fully built version received Chrysler's 5.2-liter V8 engine and a four-speed manual gearbox, although an automatic unit was available.

[19] The car also received rudimentary protection from the elements in the form of loose side windows and a simple hood.

Roger P Allard's, Allard Motor Works, located in Montreal, Quebec, Canada, builds what their website calls "a modern hand-crafted version of the famed British competition roadster that stirred crowds in Europe and North America", known as the J2X MkII.

Allard engineers hand built the car at a rate of 100 per year, while keeping it in compliance with modern standards for automotive safety.

[25] In 1951, Bill Pollack drove an Allard J2 with a Cadillac V8 to victory at the Pebble Beach Road Race.

[26] Sydney Allard and Tom Cole drove a J2 with a Cadillac engine to third place in the 1950 24 Hours of Le Mans.

Arriving later during a time when sports racing car design was developing rapidly, the J2X was not as successful in international racing as the J2, as it was not as competitive when compared to more advanced C and later D type Jaguars with disc brakes, alongside Mercedes, Ferrari, and Maserati works entries.
