Toyota against new hybrid power limits for 2017 WEC

An extension of the new limit on hybrid power for next year's Le Mans 24 Hours to the rest of the World Endurance Championship in 2017 is opposed by Toyota

Toyota against new hybrid power limits for 2017 WEC

The Japanese manufacturer is arguing that the rule limiting hybrid power release to 300kW would hurt its concept more than those employed by rivals Audi and Porsche.

It says it agreed to because the rule change will have a negligible effect on performance courtesy of the proliferation of long straights.

But Toyota argues that the sharper burst of energy release required on other tracks where the straights are shorter would disadvantage its hybrid concept because it is the only manufacturer to deploy through both axles.

LMP1 manufacturers at odds over future tech rules

Toyota Motorsport technical director Pascal Vasselon told Autosport: "This kind of limitation hurts a double KERS [kinetic energy retrieval system] more than one KERS and an exhaust system.

"It is not fair to introduce a rule that hurts one technology more than another."

Vasselon expressed surprise that the rule makers, the FIA and the Le Mans organiser the Automobile Club de l'Ouest, wanted to extend the rule to the Formula 1 tracks that make up the rest of the WEC in 2017.

"It is difficult to understand, because what was discussed originally was to apply the limit only to Le Mans because it is a grade two circuit," he explained.

"The delivery is not so important because the straights are very long; we were surprised at the suggestion that it could be applied generally."

Vincent Beaumesnil, sporting manager at the ACO explained the thinking behind the extension of the 300kW rule by saying it was "best to have one rule for all circuits, because otherwise it is confusing".

The 300kW limit pre-empts a projected change to the way circuits are licensed by the FIA.

Under a system that has yet to be signed off, the grading of a circuit would be determined by power to weight ratios of the cars allowed to run on it.

The standout memories of Le Mans 2021

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.

How overlooked Mazda produced one of Le Mans' greatest shocks

The screaming rotary-engined Mazda 787 is regarded as one of the most popular Le Mans 24 Hours-winning cars, but until its surprise success on this day 30 years ago it was never regarded as a likely victor. But that reckoned without a new technical partner, some canny political manoeuvring and a rival's bizarre self-inflicted weakness

One more would put him level with his nation's favourite son, but there's another prize he would value far more than the honour of matching Juan Manuel Fangio's tally
