Fernando Alonso moved the No. 8 Toyota TS050 Hybrid into the lead of the Six Hours of Spa-Francorchamps at the halfway point after the Japanese marque’s No. 7 car encountered a sensor failure on its hybrid unit.
Kamui Kobayashi had built up a one-minute advantage over Alonso during the third hour but a mechanical issue forced the Toyota Gazoo Racing team to wheel its No. 7 car into the garage.
Alonso handed over to Kazuki Nakajima moments after their sister car encountered its problem, with the Japanese driver inheriting a two-minute advantage over Gustavo Menezes in the No. 3 Rebellion R13 Gibson.
SMP Racing’s No. 11 BR Engineering BR1 AER ran 40 seconds behind the Rebellion at the close of three hours with Vitaly Petrov behind the wheel.
The No. 7 Toyota, which started from pole. emerged from the pits after around 10 minutes of treatment and is now running five laps down on the leader with Jose Maria Lopez behind the wheel.
The No. 7 retained its early lead after a series of safety car and full course yellow periods shuffled the LMP1 order around during an eventful first couple of hours.
Kobayashi’s co-driver Mike Conway led away from pole but allowed Sebastien Buemi past when he overstepped the Bus Stop chicane.
The Toyotas then switched positions again when Buemi made an extra pit stop during a safety car procedure which handed the No. 7 a sizeable advantage for when Kobayashi got in.
The Japanese driver then set about increasing his gap to Alonso, who had an uncharacteristic spin when he touched the damp outside curb at Pouhon, before the hybrid system sensor failure occurred.
In GTE-Pro, Alex Lynn put the No. 97 Aston Martin Vantage GTE in front by powering past Davide Rigon’s AF Corse Ferrari 488 GTE Evo into Blanchimont.
