In 2005 Kerr became the lead driver for A1 Team Great Britain, partner to Alex Lloyd. Robbie raced in the 2005–06 rounds except the season finale in China, and came close to winning on several occasions. At the feature race at the inaugural round at Brands Hatch after a successful pitstop he was in the lead ahead of A1 Team Brazil until the battery failed in his car. At Dubai Autodrome he had the lead for most of the feature race until he was passed by A1 Team France's Nicolas Lapierre. Kerr performed well in the next round on the Durban street circuit, South Africa, where he finished second in the sprint race, and held the lead briefly in the early stages of the feature race, only for a pipe to get lodged underneath the car in his pit stop, he came in again on the next lap to get it removed but damage to the floor of the car led to Kerr's retirement. He then took A1 Team Great Britain's first ever A1 Grand Prix pole position in the next round in Indonesia, but he lost out in the races, failing to turn those pole positions into a win, and in Mexico he struggled in qualifying, ended up down the order in unfamiliar territory, and just missing out on the points in the sprint race in 11th, but improving in the feature race to 6th position. At Mazda Raceway Laguna Seca Kerr raced his last two races for A1 Team Great Britain in the season. In a rain-sodden sprint race Kerr finished 4th behind Mexico, France and Portugal. In the feature race he finished 3rd behind Mexico and A1 Team Germany. Kerr did not race at Shanghai to prepare for the 2006 World Series by Renault, and his place was taken by Indy Racing League driver Darren Manning. The following season, Kerr returned to Team GBR for A1GP, though his World Series by Renault commitments prevented him from making the first round of the season at Zandvoort. He was again replaced by Manning. For this whole season, Kerr will be supported by Manning and young British Formula 3 star Oliver Jarvis.
For the 2006 season, Kerr joined Sean McIntosh in the KTR team racing in the 2006 Formula Renault 3.5 Series season. Success was limited during the season with a best finish of 4th, then a fastest lap in the final round, resulting in a 17th finish in the overall standing.
Recent drives
Since the solitary season of Formula Renault, Kerr has driven only sporadically and across different series. He had several sportscar outings in 2008 and 2009, a guest drive at the Silverstone round of the Porsche Carrera Cup in 2010 and a season of the Speed Euroseries in 2011. Kerr returned to sportscars in 2012 and 2013 picking up some drives in the FIA World Endurance Championship with a 2nd place in the LMP2 class at Interlagos.
