LA 2011: Subaru BRZ Concept – STI

News I By Brandon Turkus I November 01, 2011
We’re getting closer and closer to the start of the 2011 Los Angeles Auto Show, and with it, the official unveiling of the hotly anticipated rear-wheel-drive Subaru BRZ (and its platform mate, the Scion FR-S/Toyota FT-86). In the mean time, Subaru has released this teaser of an STI-ified version of the BRZ.
 
According to the photos and press release, the BRZ Concept – STI is intended as a preview of the production model, as well as what the maniacs at STI will do if they get their hands on the shapely rear-driver. The BRZ STI brings a number of upgrades to the table, including a new body kit, rear spoiler, diffuser, eighteen-inch STI-branded wheels, Brembo brakes, and a suspension tuned by STI. This concept also features a number of weight saving measures, including a carbon fiber roof.
 
Despite this being a concept, it should be considered a pretty fair depiction of a production BRZ STI. It also gives us the best idea yet of what the production BRZ looks like. We’ll have more on the rear-drive Subie when it makes its official debut at the 2011 LA Auto Show.

LOS ANGELES, Nov. 1, 2011 /PRNewswire/ — Subaru of America, Inc. announced today that it will show an all-new concept version of its upcoming BRZ sports car at the 2011 Los Angeles International Auto Show. Dubbed the Subaru BRZ Concept- STI, the concept car represents the next step in lightweight performance sports cars combined with the race-bred tuning of Subaru Technica International (STI).

The first BRZ concept car to be shown with bodywork, the Concept – STI strongly hints at the styling of the production BRZ and features unique STI performance features.
 
Styling
 
Sleek, low and tightly coiled bodywork blends with STI performance touches for a sporting profile. A hexagonal front grille, hawk eye headlights and fin-shaped fog lamps are instantly recognizable as Subaru. The exterior colour "WR Blue Pearl II" is a new generation of the iconic WR blue paint scheme that has adorned both racing production STI’s.
 
The body is set-off with aero-tuned lower front spoiler and unique rear fascia, a rear wing for added down-force and a carbon-fiber roof to lower its already record setting center of gravity specification. The rear design features bold rear fender flares and large rear-diffuser giving way to polished stainless-steel quad-tailpipes. Vented rear bumper corners contribute to improved aerodynamics performance.
 
Engine
 
The concept car employs the totally new Subaru "FA" Boxer engine exclusively designed for the RWD BRZ sports car. In order to achieve properties best-suited for the BRZ sports car, the overall structure of this 2.0-liter naturally-aspirated four-cylinder boxer engine has been designed with a square bore and stroke of 86 X 86 mm. The inherent qualities of the Subaru Boxer engine were mated to a direct injection fuel system, which further improves combustion efficiency, running smoothness up to high rpm and high environmental standards.
 
Chassis
 
The lightened Concept – STI features an STI-tuned suspension, Brembo brakes and unique 18-inch wheels and tires. The Subaru-engineered and built chassis boasts a rigid frame housing a two-plus-two interior and front engine/rear-wheel drive layout. With the engine mounted low and rearward in the engine compartment to allow for near-perfect balance and one of lowest CoG’s of any car on the market. 
 
The BRZ Concept – STI is designed to combine lightweight, a low polar moment and razor-sharp reflexes for the ultimate handling machine. The low engine placement also allows for a very low and blade-like hood design. Short front and rear overhangs reduce the yaw moment of inertia.
 
Compared with other Subaru models, which already feature a low centre of gravity and optimal weight distribution, the engine in the Subaru BRZ – STI – sits even lower, 4.7 inches lower in fact and is positioned 9.4 inches closer to the centre of the chassis.
 
The first RWD Subaru, the production Subaru BRZ will begin production in spring 2012 as the only mass-produced front-engine, Boxer engine rear-wheel drive sports car in the world.
