As one of the most anticipated Japanese sport coupes in history, Subaru BRZ was criticized that the 200-horsepower output simply just isn’t enough. So the automaker has already started working on an STI model of the BRZ. Atoshi Atake,Subaru’s global marketing manager, advised Auto Express, “Let me say this – we will definitely satisfy our customers. We are already focusing on a faster version.”
The news should seem as no surprise, considering Subaru showed a BRZ STI concept at last year’s Los Angeles Auto Show. It’s very likely that a production version will closely look like the concept, down to the aerodynamic car body and lowered suspension. We’re not certain the oversized rear wing will come as standard equipment, though.
The STI version will be lighter in weight, too, thanks to racing bucket seats, a carbon fiber hood and, potentially, even a carbon-fiber roof. Lighter wheels will be used, and the car will further benefit from upgraded brakes and a stiffer suspension for track day use.
Under the hood, the BRZ STI will most likely go a different route than current STI models. Given that there’s no room for an intercooler up front, turbocharging is out. You can cross supercharging off the list, too, as Subaru is worried that it would impact the BRZ’s fuel economy and demand a larger gas tank.
As an alternative, Subaru will enhance the car’s air intake, add a less-restrictive exhaust, boost redline to 7,500 rpm and revise the variable valve control system for optimized performance. These modifications are expected to improve output to around 250 horsepower, a full 25-percent increase over the base model.
