Makinen explains Yaris WRC battery problems
Toyota Gazoo Team rally manager, Tommi Makinen, explained the reason why Jari-Matti Latvala had battery failure.
Makinen that the lightweight batteries fitted to the cars were not designed to be recharged when the engines were operating at full power.
This is why the batteries often failed at the ends of stages, which had also happened to the Hyundai of Dani Sordo.
Compounding the problem was the heat build-up under the bonnet when the cars are not moving and no air passes through the cooling package.
Makinen said the battery problem had been well noted and was not an ongoing concern to the Toyota team.
Toyota’s previous power-loss problems at high altitude in hot conditions had been successfully addressed and did not affect the team cars this year.
It was the second successive year that Latvala had the battery problem on this event.
