2003 German 500

The 2003 German 500 was a Championship Auto Racing Teams (CART) motor race held on May 11, 2003 at EuroSpeedway Lausitz in Klettwitz, Brandenburg, Germany. It was the fifth round of the 2003 Champ Car World Series and the second and final running of the event. The 154-lap race was won by Newman/Haas Racing driver Sébastien Bourdais. Mario Domínguez of Herdez Competition finished second and Team Rahal's Michel Jourdain Jr. came in third.

Bourdais set the fastest time of qualifying and won the pole position. Prior to the race, Alex Zanardi drove 13 laps around the circuit in honor of the laps he never completed in the 2001 American Memorial due to his near-fatal crash. Bourdais and his teammate Bruno Junqueira traded the lead several times before Domínguez passed them both on lap 35. Domínguez's blocking tactics against Bourdais were deemed too aggressive by CART and he was issued a penalty, allowing Bourdais and Junqueira to continue their battle for the lead. After the final round of pit stops, Bourdais reclaimed the lead, but received immense pressure from Domínguez's multiple attempts to pass him. Bourdais ultimately fended off Domínguez and earned his second consecutive CART victory.

With Paul Tracy struggling to materialize a fast pace due to an overabundance of downforce on his car, he was left tied with Junqueira for the lead in the Drivers' Championship. Bourdais' win boosted him from sixth to fourth place in the standings. Lola widened their lead over Reynard in the Constructors' Championship with 13 races left in the season.
