In 1991, Reynard Motorsport were commissioned by Walter Lechner to build a sports prototype for the Division I class of the Interserie.
The car they built was called the Lechner Spyder SC91, and used a 3.5-litre Judd V10 engine,[1] similar to one used in Formula One.
[2] Two weeks later, he competed in the next round, held at the Österreichring; Lechner took fifth in the first race,[3] and sixth in the second,[4] resulting in him being classified in fifth overall.
[41] Lechner favoured the Lola Horag HSB for 1994, but would use the Reynard Spyder one last time; in the final round of the season, held at the Österreichring.
[44] This would, however, prove to be the last time that Lechner raced the Reynard Spyder, as he opted to use the Lola Horag HSB for the next couple of years.
[48][49] At the A1-Ring, Neuhauser took his first victory with the car, beating Karl-Heinz Becker's modified Minardi M190 by 21.4 seconds.
[53] Neuhauser won the Division I driver's title for 1997, beating Ranieri Randaccio by 11 points.
[54] Neuhauser remained in the Reynard Morag for the 1998 Interseries season, but switched to Achleitner Motorsport.
[67] Neuhauser slipped to third in the driver's championship, finishing 1.5 points behind second-placed Michael Schuster's Argo JM19C.
