Action at the Circuit of the Americas begins with a test day on Thursday
The surprise of the session was the No.12 Rebellion Racing Lola-Toyota of Neel Jani, Nick Heidfeld and Nicolas Prost which was 4th fastest, 1.029s behind the lead Audi but ahead of both works Toyotas.
Toyota’s position as world leader in hybrid vehicle technology was emphasized earlier this month when the company passed the 5 million mark for sales of hybrid road cars.
But both TS030 HYBRID cars lost positions to the two Audis mainly because track temperatures did not suit the chosen Michelin tyre compound.
Following three wins from six races in 2012, the team arrived in Britain with two 2012-specification TS030 HYBRID cars.
After an impressive debut in the WEC in 2012, which included three victories in just six races, the team returns with an ambition to win both the Le Mans 24 Hours and the WEC title.
