Following Klaas Zwart's purchase of Ascari Cars in the late 1990s, he entered the team in sports car racing, initially using the Ascari Ecosse in 1999, before building the A410 in 2000. The A410 was a LMP900-class car and took its name from the 4-litre Judd GV4 V10 engine it was fitted with. The A410 was based on the Lola T92/10 Group C racing car and featured a similar chassis design and suspension. Although distinguishable from the T92/10 by its open bodywork – the T92/10 had a closed cockpit – the A410 used styling cues from the T92/10, such as the flat-nosed front end. The 4-litre V10 engine was related to the T92/10; the Judd GV4 was a larger version of the 3.5-litre GV10 unit featured in the earlier car, which originated as a Formula One engine. Two cars were built and debuted in 2000. In 2002, both cars were renamed the KZR-1 and shipped to America.
The A410 had a carbon fibre monocoque chassis, with double wishbone suspension, with push-rod actuated coil springs and dampers at both ends. The naturally-aspirated Judd GV4 engine produced around 600 hp (447.4 kW; 608.3 PS) at 10,250 rpm, and 450 N⋅m (332 lb⋅ft) of torque at 8,500 rpm. Although the power output was similar to that of the Audi R8, a successful LMP900 car, the naturally aspirated engine produced roughly 250 N⋅m (184 lb⋅ft) less torque than the R8’s twin-turbocharged V8. The A410 used a 6-speed sequential gearbox, driving the rear wheels, and featured carbon fibre disc brakes.
The A410 debuted in the 500 km of Silverstone in 2000, but gearbox problems prevented it from racing. Team Ascari then attempted to compete in the 24 Hours of Le Mans, but were not invited due to not having attended the Le Mans Test. Zwart entered himself alongside Werner Lupberger and Jeffrey van Hooydonk at the 1000 km of Nürburgring, but the car retired after 41 laps due to another gearbox failure. At the Brno round of the Sports Racing World Cup, an A410 finished a race for the first time; Lupberger and Zwart finished 19th, and last overall, twelve laps behind the next car. This was the only time the A410 finished a race in 2000; the team retired at Donington Park without completing a lap due to electrical issues, and suffered further problems at the Nürburgring after 27 laps. A spin after 29 laps ended the team’s participation in the final race of the Sports Racing World Cup season at Magny-Cours.
Mike Phillips attempted to enter an A410 at the 24 Hours of Daytona in 2001, but did not attend the race. The Sports Racing World Cup had been renamed to the FIA Sportscar Championship, but the A410, now driven by Lupberger and Ben Collins, started the season with a retirement at Barcelona after 74 laps, when the engine blew with half an hour remaining. At the Donington Park round of the European Le Mans Series, both A410s were entered; however, the A410 of Patrick Lemarié did not start due to engine problems, and Lupberger and Collins retired after 54 minutes – and 35 laps – due to a gearbox issue. The 1000 km of Monza, part of the FIA Sportscar Championship, saw the first success for the A410; Collins and Lupberger finished second, 7 seconds behind the Ferrari 333SP-Judd of Giovanni Lavaggi and Christian Vann. The team continued their improved form at Spa-Francorchamps, finishing fourth, a lap down, and setting the second fastest lap of the race. Lupberger and Collins were partnered by Harri Toivonen for the 24 Hours of Le Mans in the A410-001 chassis, whilst Zwart partnered Xavier Pompidou and Scott Maxwell in the other car. Neither finished; the A410-001 retired due to a fuel pump issue after 11 hours and 134 laps, and the other car crashed out after 15 hours and 66 laps. Returning to the FIA Sportscar Championship, Collins and Lupberger took fourth-place finishes at Brno and Magny-Cours. The team won at Donington Park by almost a minute, for the car's maiden victory. At Mondello Park, the team finished ninth overall, and sixth in the SR1 class. In the final race of the season at the Nürburgring, the car was disqualified from third place due to dimensional issues. Team Ascari finished the season in fourth, with 71 points; nine behind Racing for Holland in third, but 30 ahead of R&M in fifth. Their single European Le Mans Series race resulted in an eighth-place classification, with 11 points.
Following the cars’ export to America, the KZR-1s debuted at the 24 Hours of Daytona; Lupberger and Toivonen were partnered by T. J. Bell in the A410-001 chassis, whilst Collins, Zwart and Vann drove the A410-002 chassis, which was also fitted with a BMW 4-litre V8 engine. The A410-001 was classified 38th overall, and ninth in the SRP class, but retired due to a blown engine after 15 hours and 429 laps, while the other car was classified 70th, and 16th in class, due to electrical issues after six hours and 116 laps. At the 12 Hours of Sebring, Kristian Kolby replaced Toivonen, and Justin Wilson replaced Zwart; Collins, Vann and Wilson finished sixth overall, while the other car finished 29th overall, and tenth in class. For the 24 Hours of Le Mans, Team Ascari entered one KZR-1, driven by Lupberger, Collins and Bell; however, an accident caused by suspension failure after an hour and 17 laps forced their retirement. Team Ascari’s last entry of the season came at the Cadillac Grand Prix, but neither car competed. Team Ascari were classified tenth in the ALMS Team's Championship, with 19 points.
For 2003, the KZR-1s returned to Europe, and Lupberger, Zwart and Charles Hall drove one in the third round of the FIA Sportscar Championship, held at Monza, finishing second overall, albeit a minute and a half behind the winner. Zwart and Lupberger experienced driveshaft failure with just over 15 minutes remaining at Donington Park, having completed 83 laps. Although Team Ascari entered the 1000 km of Spa, they did not attend the race, and the car was retired. Their single race finish saw them finish joint-seventh in the FIA Sportscar Championship Team's standings, level with Promec Engineering on eight points. From this point onwards, Ascari focused on the production of the Ascari KZ1 supercar – which formed the basis of the KZ1-R GT3 racing car – and racing Zwart's classic Formula One cars in the EuroBOSS series.
