The McMurtry Spéirling is an electric single-seat prototype sports car which was first presented at the Goodwood Festival of Speed in 2021.

[4] It is not currently in a racing series but is built to satisfy relevant motorsport safety requirements, with crash structures and a carbon-fibre monocoque chassis with integral rollover protection.

[8] The car, developed in secrecy over three years, was first presented at the Goodwood Festival of Speed on 8 July 2021, and driven by Derek Bell.

On 26 June 2022, the Spéirling achieved a new Goodwood Festival of Speed hill climb record, completing the 1.87-kilometre (1.16 mi) course in 39.08 seconds with McMurtry test driver Max Chilton behind the wheel.

[15] The use of fans powered by separate motors to provide downforce was first conceived of by Jim Hall for the Chaparral 2J, a Can-Am car he designed, constructed and raced in 1970.
