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.
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.
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.
Doran's SP1, which was slightly 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.
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 Le Mans, Rollcentre entered a lone car, and performed well and at 6.30 am on Sunday, they were running in 4th place overall (in the teams first Le Mans 24) until they were taken out in a large accident for team owner Martin Short caused by damage from a previous incident where the Pescarolo driven by Sebastian Bourdais ran into Short, causing unseen damage to the left rear suspension, which subsequently failed in the Porsche curves.
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.
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 Nismo engine.
A power steering fluid leak as night came on caused serious issues, requiring the team to pit stop almost double the nowmal amount and the race was gone.
Chassis 004 was sold to the USA by Rollcentre, but then found its way back to the UK, now owned by James Cottingham, and Max Girado.
