Subaru unveiled today the new BRZ Concept STI at the 2011 LA Auto Show, a vehicle that hints at the production BRZ and features unique STI performance features. The first visual impact with the concept shows the “WR Blue Pearl II” color, a new generation of the legendary WR blue paint scheme that has adorned both racing and production STI’s.
Moreover, a carbon-fiber roof was added in order to lower the center of gravity, one of the lowest of any car made. Under the hood we find the 2.0-liter naturally-aspirated four-cylinder boxer engine, designed with a square bore and stroke of 86 X 86 mm.
The Subaru BRZ Concept - STI features a tightly coiled yet sleek bodywork that complements its STI performance. At first look, onlookers will immediately recognize the concept as Subaru because of its hawk-eye headlights, hexagonal lower front grille, and fin-shaped fog lamps.
Blending design with aerodynamics, the concept dons an aero-tuned lower front spoiler, unique rear fascia and a rear wing -- all helping to create additional downforce. Likewise, the concept’s center of gravity is now lower thanks to a carbon fiber roof.
At the rear, bold fender flares and large diffuser give way to stainless-steel quad-tailpipes. The car’s aerodynamics is further enhanced by vented rear bumper corners. The Subaru BRZ Concept - STI is wrapped in “WR Blue Pearl II” exterior color, which is a new generation of the WR blue paint scheme used in both racing and production STI’s.
Additionally, the Subaru BRZ Concept – STI features an STI-tuned suspension, distinct 18-inch wheels and tires, and Brembo brakes. It features a chassis with a rigid frame that contains the car’s two-plus-two interior and front engine/rear-wheel drive layout.
For a near-ideal balance, lower center of gravity and optimal weight distribution, Subaru mounted the engine low and rearward in the compartment. It is around 4.7 inches lower than in a typical Impreza and is placed 9.4 inches closer to the center of the chassis.
This placement allowed Subaru to implement a very low and blade-like hood design for the BRZ - STI. The concept likewise features short front and rear overhangs to trim the yaw moment of inertia. AS for the heart of the concept, Subaru chose to fit its new “FA” 2.0-liter naturally aspirated four-cylinder BOXER engine that was exclusively designed for the RWD BRZ sports car.
To better suit the engine for the BRZ sports car, its overall structure has been designed with a square bore and stroke of 86 X 86 mm. The engine features direct injection fuel system that enhances fuel combustion and thereby ensuring efficiency and smoother high rpm.
