Most motorsport enthusiasts will agree that Group C era of the 1980s and early 1990s was one of the most exciting of the recent decades. Almost all major manufacturers had a go at Group C at one point or another and the cars they built were nothing short of spectacular. Towards the end of the '80s, sports car racing was attracting so much attention that Formula 1, the 'pinnacle' of motorsport, started to suffer. To interest more manufacturers to jump from sports cars to Formula 1, the FIA changed the Group C regulations dramatically. The engines were to be limited to a displacement of 3.5 litres, on par with the contemporary F1 engines. Although it helped to attract some manufacturers to enter F1, it had a devastating effect on sports car racing and most of its competitors retired from racing altogether.
It was in this difficult climate that an ambitious Chris Humberstone decided to embark into sports car racing as an independent manufacturer. He had previously worked for a long line of racing teams and manufacturers. Instead of naming the newly founded company (after) himself, he revived a long dormant name; Allard. Humberstone had already contacted the son of company founder Sydney Allard a few years earlier, but it would take until the early 1990s before he could found Allard Holdings. Apart from the racing program, he also planned a line of Lexus-based limited production road cars. After securing financial backing from several parties, Humberstone assembled a crew of highly talented engineers and designers and development of the racing car commenced.
In their quest to achieve as much downforce as and as little frontal area possible, the designers came up with a highly unconventional shape. At the time most Group C cars had very smooth all-enveloping designs, which could not be said of the new Allard J2X-C. In fact the basic shape was closer to that of a single seater racer with separate front fenders, harking back at its namesake; the great cycle fendered Allard J2X of the 1950s. The areas between the nose of the car and the separate fenders were filled with large wing-shaped sections that generated a massive amount of downforce and also hid the suspension parts from plain view as per the Group C regulations. The separate fenders were still easily distinguishable from the side, further accentuated by the fully exposed floor next to the bubble-top cockpit.
Under the advanced carbon fibre body, an equally advanced carbon fibre monocoque was found. It was unusual in that it stretched all the way to the rear suspension, instead of using the engine as a fully stressed element. Hoping to eventually convince a manufacturer, possibly Lexus/Toyota, to build a bespoke engine, the team made do in the mean time with a Nicholson McLaren modified Cosworth DFR V8. It was mated to a March six-speed gearbox, which was also came straight from Formula 1. Suspension by double wishbones, all-round with coil springs over dampers actuated by push-rods. Stopping power was provided by carbon ceramic discs.
Little over two years after the project commenced, the first Allard J2X-C was completed. It was shaken down in Wales during July of 1992 and further tested across the pond in the following months. It was obvious that the quest for downforce had been successful, but the car produced more drag than the under-powered Cosworth engine could overcome. Another problem was the full length monocoque, which made maintenance to the engine and gearbox difficult. At the time Allard had taken a controlling stake in Spice and one of the company's backers, Costas Los, raced a Honda engined Spice in the American GTP championship. Honda showed interest in the Allard J2X-C program and Humberstone hoped he could convince them in supplying their V10 Formula 1 engine. Unfortunately the Japanese manufacturer opted to branch out into Indy racing.
Early in 1993, it quickly became apparent that the project had been too ambitious for Humberstone's small team and before the J2X-C was ever raced, Allard went into receivership. For an absolute bargain of £76,000 all assets were bought by (historic) racer Robs Lamplough. He had former Allard employee Gordon Friend prepare the car in time for the official test at Le Mans. He was faced with a few problems. Some were small and others, for example the tub having never been crash tested, were pretty major. A detailed explanation to the FIA as to how the car was built fortunately proved to be sufficient to get a certificate. The final hurdle was the lack of any lights, which Friend solved by fitting four BMW headlights under a Perspex cover in the front fender.
Still in bare carbon fibre, the J2X-C made its official debut at the Le Mans test. Considering the car's high downforce and drag body, it was no surprise that the Allard was off the pace considerably. Compared to the Peugeot 905, which was built to the same specifications, the J2X-C was 50 mph too slow down the Mulsanne straight. Instead of entering the race, Lamplough decided to take the car to the United States. The twistier tracks would suit the car much better. It was entered in a race only once; the GTP round at Laguna Seca. Lamplough qualified the car in twelfth position and finished the race in ninth. After the race, the Allard was shipped back to England and retired from racing. It was also the last season for Group C; sports car racing would never be the same.
The Allard J2X-C remains as one of the very last Group C racing cars built and one of the very few raced without the support of a major manufacturer. More importantly, it inspired designers in the years to come and its influence can in particular be seen in the most recent generation of sports racing cars. In the last few years, the car saved from oblivion by its current owner, who brought it back to full running order and also by Mike Fuller, who published a detailed account of the Allard's design and history in Race Car Engineering magazine and on his fabulous Mulsanne's Corner website. Fully restored to the red livery, Allard had originally intended to run the car in, the sole J2X-C is shown above during the 2007 Goodwood Festival of Speed where Group C's 25th anniversary was celebrated.
… but it is certainly advanced. With the proper power it could probably still race competitively today. I wonder if the FIA/ACO will ever see reason, and de-regulate their series to let cars this interesting race again.
