A Subaru executive in North America has explained why the new, second-generation BRZ doesn’t employ a turbocharger.

The fresh-faced BRZ upgrades from the old 2,0-litre horizontally opposed four-cylinder engine to a likewise naturally aspirated 2,4-litre flat-four unit, with peak outputs of 170 kW and 249 N.m.

Dominick Infante, who heads up public relations for Subaru in the United States, told Road & Track adding forced induction to this powerplant would have resulted in various “compromises”.

Of course, Subaru already employs a turbocharged version of this FA24 engine in the Ascent three-row SUV, where it makes 194 kW and 376 N.m. But Infante said the turbocharger is fitted at the bottom, something that would require the BRZ’s engine to be raised. This, in turn, would have significantly hiked the little sportscar’s centre of gravity. As a reminder, the Japanese firm says the new 2+2 model’s centre of gravity is “even lower” than that of the original and “on par with exotic hypercars”.

In addition, Infante said adding a turbocharging system would have increased weight (and cost), in conflict with the original lightweight philosophy of the car. He also pointed out the new FA24 engine boasts a slightly higher redline (at 7 500 r/min) than the outgoing powerplant, with peak torque increasing some 44 N.m and arriving far lower in the rev range (now 3 700 r/min).

So, will we see the new BRZ on local roads? Well, Subaru Southern Africa has seemingly yet to decide, telling us “a number of factors” will ultimately determine whether or not the newcomer is offered here.
