Input: Question: What year did Rene Wolff begin his racing career? Passage:Arnd Meier (born March 1, 1973 in Hannover, Germany) is a former race car driver. After finishing second in the 1996 German Formula Three Championship behind Jarno Trulli, but ahead of teammate Nick Heidfeld, Meier participated in the 1997 and 1998 seasons of the CART World Series for Project Indy and Davis Racing. He led for two laps on his Champ Car debut in Australia, largely as the result of pit strategy. For much of his time in Champ Car, he drove the only Lola chassis in the field, at a time when Lola were struggling to match the pace of the dominant Reynard chassis. Among his 29 starts, his best finish was 10th place at Road America in 1998. In 1999, Meier returned to Europe to race in F3000 and touring cars. In 2004, Meier and René Wolff drove a BMW 318i to win the BFGoodrich Long Distance Championship.
