2011 LA: Subaru BRZ Concept STI gives first hint at production model

Subaru’s upcoming BRZ model has an STI variant concept that has been revealed at today’s Los Angeles International Auto Show. The BRZ Concept-STI is the brand’s latest representation of its lightweight performance sports car models.

This concept is a good preview for what’s to come for production, as Subaru is updating its style but still keeping its distinctive details.

Power for the concept comes from a front mounted, completely new horizontally-opposed Subaru FA Boxer engine crafted specifically for the RWD BRZ model. The motor is a naturally-aspirated four-cylinder displaced at 2.0-liters, with a square bore and stroke at 86 x 86 mm. Subaru opted for direct fuel injection to stay up to environmental standards, and keep the engine running smoother at higher rpms.

Stiff tuned suspension, rear-wheel drive, a low, rearward mounted motor, and a set of Brembo breaks with 215/45R18 (front) and 225/45R15 (rear) tires, combine for balanced weight distribution and STI level performance. In comparison to the Subaru Impreza model the STI engine sits 4.7 inches lower and 9.4 inches closer to the chassis’ center. The body of the car is sized 166.7 x 70.9 x 50.4 inches, with a 101.2 inch wheelbase.

Subaru’s BRZ model will be the only of its kind when prodction kicks off in spring 2012, as the only front-engine boxer with rear-wheel drive to be mass produced.
