History

The Allard J2X was an independently designed 3.5-litre Group C prototype, built from 1992 to 1993 according to ultimatecarpage. It had a mid-mounted Ford DFR V8, a carbon and honeycomb survival cell and a six-speed gearbox.

Race entries list an Allard J2X Ford at the 1992 Suzuka 500 km (entrant Terai Engineering) and at the 1993 Laguna Seca race, where it finished ninth for Bob Pond Racing with Robs Lamplough driving. A 1993 Le Mans test result also lists the car, placed 19th.

Mulsanne's Corner describes the car as a flash in the pan that did not realise its potential. The entries are listed by the race results pages and are not checked against the chassis history.
