Audi WEC star Andre Lotterer is set to make his F1 debut at Spa this week in the Caterham usually driven by Kamui Kobayashi.
The team will probably make an announcement tomorrow pending official confirmation of his FIA Superlicence, after documentation was delayed in transit.
The initial deal will be for one race, and it remains to be seen whether it is extended, or what Kobayashi’s future with the team will be.
The opportunity comes some 14 years after Lotterer first tested a works Jaguar R1 as a teenager, and as such he will presumably set a record for the longest gap between testing and racing an F1 car.
Lotterer has been given dispensation by his TOM’S team to miss this weekend’s Super Formula race in Japan.
It’s understood that there is no sponsorship attached to the German, and his role is to provide extra feedback. He has strong connections with Caterham advisor Colin Kolles, for whom he drove in LMP1. Lotterer’s close pal James Rossiter, who also has Kolles connections, has also been in the Caterham frame.
