The switch of front and rear wheel and tyre sizes on the Toyota GR010 HYBRID outlined by Autosport late last month has been confirmed, along with aerodynamic revisions necessary as a result of the change to maintain airflow and remain within the performance windows laid down by the LMH regulations.
The revised Toyota, which will race for the first time in the 2022 WEC season opener at Sebring on 18 March, is now running 12.5 inch wide front wheels and 14in rears rather than 13in wheels it ran at all four corners last year.
These are the two options currently allowed in the rules and were devised to reflect the different requirements of four-wheel-drive hybrids and cars with rear-drive only.
Pascal Vasselon, technical director of Toyota Gazoo Racing Europe, explained the change has been designed “to address challenges we faced last season with management of the rear tyres”.
