This alloy-bodied roadster is a re-creation of a works car produced by Allard for the 1952 24 Hours of Le Mans. Commissioned by the seller in 2016, the car was built over several years by marque specialist Dr. Jonathan Rose in the UK using a modified P-series chassis, hand-formed bodywork, and a 331ci FirePower Hemi V8. After initial assembly was completed, the car was outfitted for vintage racing by Project Heaven near Peterborough, England, using components sourced from Hot Heads Research in the US. An FIA Historic Technical Passport was issued in 2021, and the car has been driven in events such as the Goodwood Revival, Silverstone Classic, and RAC Woodcote Trophy. A timed speed of 157 mph was reportedly achieved along the Mulsanne Straight during the Le Mans Classic. Updates over the past few years have included a hydraulically actuated four-speed manual transmission, an Allard quick-change differential, and LEDA adjustable dampers. This J2X Le Mans re-creation is now offered in the UK with an FIA Historic Technical Passport and UK V5C registration.

The Le Mans variant of the J2X Competition was developed for the 1952 iteration of the endurance race, which required barchetta bodywork fully surrounding the wheels. Allard’s entries featured a forward-tilting front clamshell with covered headlights and a mesh screen over the carburetor scoops.

Dr. Jonathan Rose fabricated this car’s alloy bodywork, forming panels over a plywood buck. Tubular steel supports were added to a modified P-series chassis along with suspension components and other parts accumulated by Dr. Rose over many years.

The car is finished in green with #29 roundels that were applied for participation in the Le Mans Classic. Details include a single windscreen, a gray roll hoop, a Le Mans-style fuel filler, bullet-style side mirrors, an LED racing light, and dual exhaust outlets.

Turrino 16” alloy wire wheels are secured by two-eared spinners and wrapped in Dunlop Racing tires. The suspension incorporates a split front axle, a de Dion rear end with a Panhard rod, and LEDA adjustable dampers at all four corners. Braking is handled by hydraulic drums.

The right-hand-drive cockpit features seats trimmed in green leather. A fire-suppression system has been added along with HANS-compatible harnesses, a VBOX camera, a Racelogic lap timer, and toggle-switch controls. Wear on the upholstery can be viewed in the gallery.

The wood-rimmed steering wheel sits ahead of a 150-mph speedometer with an insert oil pressure warning light as well as a tachometer and auxiliary gauges. The five-digit odometer shows 20k miles.

The blueprinted and balanced 331ci Chrysler Hemi V8 features forged pistons and connecting rods, ported-and-polished heads, quadruple Rochester 2G carburetors, and wrapped headers. The seller reports that output exceeds 400 horsepower, and the car has been raced fewer than 10 hours since the most recent rebuild.

A four-speed manual transmission with a hydraulic clutch sends power to the rear wheels through an Allard quick-change differential. The seller notes that the current transmission and shock absorbers do not conform to the FIA HTP.

Photos taken at various stages of the build are presented in the gallery.

The FIA HTP is valid through 2031.

The vehicle is being sold on its registration, which serves as the ownership document in the UK. The registration lists the car as an Allard using the VIN 91P1876, which appears on the identification plate shown above, with a first registration date of 1984.
