Toyota Racing’s 2013-specification TS030 Hybrid will make its race debut at this weekend’s Six Hours of Spa-Francorchamps, the second round of this year’s FIA World Endurance Championship.

The team will field one updated car in Belgium, wearing the number seven of Alex Wurz, Nicolas Lapierre and Kazuki Nakajima.

Following their podium finish at the series-opener in Silverstone, Anthony Davidson, Stéphane Sarrazin and Sébastien Biemi will return in the 2012-spec’ number eight car.

Toyota said the priorities in the changes to the TS030 Hybrid’s chassis and powertrain have been to secure increased performance, reliability and serviceability.

A revised aerodynamic package has been introduced, including an updated monocoque, improving performance while mitigating the impact of new 2013 regulations.  These regulations have increased the minimum weight for cars in the Toyota’s LMP1 class by 15 kilograms.

The Toyota Hybrid System – Racing powertrain continues to use a unique super-capacitor which automatically delivers 300 horsepower of boost, on top of the 530 horsepower generated by the 3.4-liter normally aspirated V8 gas engine.

Toyota’s Motor Sport Division in Higashafuji, Japan, has fine-tuned the powertrain for improved power, efficiency, management of the components used and reliability, ahead of working on a completely new development in line with regulation changes for 2014.

The Spa program begins Friday May 3with practice sessions; the race will start Saturday at 2.30pm, local time.
