The new-generation coupe picks up an respectable 18kW and 37Nm over its predecessor, but Subaru has revealed why it didn’t get the forced-induction many were hoping for.
The 2022 Subaru BRZ was officially unveiled last week, but, to the disappointment of many fans, the low-slung sports coupe still doesn’t have a turbo – now the Japanese manufacturer has revealed the reason why.
The new-generation model is powered by a naturally-aspirated version of Subaru‘s 2.4-litre ‘FA24’ petrol four-cylinder ‘boxer’ engine, which sends 170kW and 249Nm to the rear wheels via a six-speed manual or six-speed torque-converter automatic transmission.
That’s 18kW and 37Nm more than the outgoing model, but still short of the 190kW, boosted figure thrown around by some pundits in the lead-up to the car’s launch.
Subaru’s head of public relations in the US, Dominick Infante, told Road & Track over the weekend that turbocharging the car would have significantly compromised handling and dynamics.
The turbocharged FA24’s design requires its turbo to be mounted to the bottom of the engine which, as he explained to the American magazine, if fitted to the BRZ, would have required engineers to raise the height of the engine within the chassis, in turn significantly raising the car’s centre of gravity.
Opting for a turbocharged powertrain would also increase the BRZ’s kerb weight and retail price, he added, compromising its mission to be an affordable, lightweight sports car ‘for the masses’.
