Cosworth Electronics will design and build the new-for-2022 hybrid system to be used in the BTCC. The electronics division of the renowned engine maker will also supply and maintain the systems. Originally mooted for introduction in 2021 after being annouced in 2017, the hybrid systems will now make their debut in 2022 as confirmed by series organisers, TOCA.
Drivers will be able to use the additional power generated by the hybrid system to either pass or defend after the first lap of each race, with the most significant gains at low rpm engine ranges. They will also control when, and how much they use vs regenerate the system, activated by a button on the steering wheel.
Initial test results performed by Cosworth Electronics suggest that the hybrid system will be most effective in low rpm engine ranges, meaning that passing opportunities out of corners could be where the extra power will be most effective. It is estimated that the weight of the new hybrid unit will be around the 65kg mark.
