Dallara SP1 - Racing History

Racing History

As part of their deal with Chrysler, Dallara promised to provide three SP1s for use in the 2001 24 Hours of Le Mans. However, in preparation for their Le Mans debut, Chrysler used the new European Le Mans Series for an opportunity to test their new car in competition. Appearing at Donington Park, the Chrysler LMP managed to qualify in fourth place behind three Audi R8s. Mechanical problems, however, saw the car finish well down the order, nearly 40 laps behind the winning R8s.

With more testing following their debut at Donington, the team was able to improve and the three Chrysler LMPs appeared at Le Mans showing some speed. One of the three entries managed to take the sixth fastest qualifying time (Olivier Beretta driving), beating out both of the Bentley EXP Speed 8s. During the race itself, the Chryslers were able to remain in the top ten for most of the race until mechanical woes took out one entry halfway through the race. In the final hours, while running fourth and fifth, another Chrysler LMP suffered a fire on the Mulsannes straight, taking it out of the race. The lone remaining Chrysler was left to take a fourth place finish, 23 laps behind the winning Audi R8.

Even with a fourth place finish in their debut, Chrysler Corporation decided that the Le Mans project was no longer fruitful, and they canceled the entire program at the end of 2001. Chrysler's partner, Oreca, decided to continue on with the program as a privateer, replacing the Mopar V8 engines with Judd GV4 V10s. Although purchasing three SP1s, Oreca decided to use a two-car effort for Le Mans while the third car would be used in the FIA Sportscar Championship. In the first race of the season, the SP1 showed its potential by finishing second behind a Pescarolo Sport, then followed this up by gaining its first win at Autódromo do Estoril. For Le Mans, the SP1s continued to show the pace they had in 2001, taking the fourth fastest qualifying time behind the trio of R8s. In the race itself, both SP1s performed well, remaining immediately behind the leading R8s and Bentley for the entire race, finishing in fifth and sixth place overall, both cars 16 laps behind the winner. Oreca would not continue with the SP1s, deciding to take a brief hiatus from prototypes to work on other projects.

Besides Oreca's efforts, one of Chrysler's former SP1s was purchased by American team Doran Racing for use in the Grand American Road Racing Championship, with drivers Didier Theys and Mauro Baldi. Doran's SP1, which was lightly modified to meet the SRP regulations yet would install the Judd GV4 (later upgraded to a GV5) like Oreca, was a championship contender in the series. In its debut at the 24 Hours of Daytona, the Doran took the overall win by six laps, earning the Dallara its first victory. Doran would continue with their winning ways by taking the next two rounds at Homestead-Miami Speedway and California Speedway, with a final victory on the season at Mont-Tremblant. Doran would end up taking second place in the teams championship, a mere nine points behind Dyson Racing. Doran would also make an appearance at the American Le Mans Series' 12 Hours of Sebring, although it would fail to finish due to an accident.

For 2003, Doran would be the only ones to use a Dallara SP1. Due to changing Grand Am regulations, the team would not return. Instead, the team would turn to the American Le Mans Series, starting the season at the 2003 12 Hours of Sebring. The car would manage a seventh place finish, again just behind a trio of Audi R8s and a duo of Bentley V8s, with a lone Panoz managing to beat out the privateer Dallara. The next two rounds saw Doran taking a fifth place finish, then a fourth. The team did not return for the rest of the season, though, quickly ending Dallara's involvement in 2003.

For 2004, two SP1s would be purchased by new team Rollcentre Racing of the United Kingdom. Rollcentre would debut at the 12 Hours of Sebring, continuing the strong performance of SP1s at Sebring by taking fifth place. Rollcentre would then concentrate on the new Le Mans Endurance Series, earning a best finish of fifth place at Monza and taking eighth place in the teams championship. For Le Mans, Rollcentre entered a lone car, and performed well until they were taken out in a large accident for team owner Martin Short caused by damage from a previous accident. Another SP1 had also been bought in 2004, by Italian squad Spinnaker Clandesteam, for use in the Le Mans Endurance Series and 24 Hours of Le Mans. This came to a quick end after the first race of LMES saw the car fail after twenty laps; the team withdrew their Le Mans entry and were dissolved.

Going into 2005, Rollcentre acquired another SP1 chassis for use in a two-car effort in the Le Mans Endurance Series. One of the two SP1s had its Judd V10 replaced with a new Nissan engine, in a partnership with Nissan Motorsports to experiment with the engine to test the possibility of Nissan providing it as a customer unit in the future. Rollcentre would also upgrade the SP1's gearbox with a paddle-shift unit. Rollcentre decided to debut their Nissan-powered SP1 at the 12 Hours of Sebring, although the car would fail to finish due to problems with the new gearbox system. Back in Europe, Rollcentre's Judd-powered car would have strong performances, including three straight podium finishes, earning the car fourth place in the teams championship. The Nissan-powered car suffered various problems throughout the season, however, scoring no points until Nissan officially ended the project and a Judd engine was placed back in the car. For Le Mans, both cars were entered, with the Nissan-powered car yet again failing to finish, while the Judd-powered SP1 took a distant 16th place finish.

Following the 2005 season, Le Mans Prototype regulations were changed, leaving the SP1s no longer legal. Although extensive modification could have allowed the SP1 to become legal in 2006, Rollcentre Racing decided to switch to a new car in a new class. Thus the Dallara SP1s career came to an end.
