Subaru - BRZ Concept STI

“SUBARU BRZ CONCEPT - STI -” to Debut at Los Angeles Auto Show

Tokyo, November 16, 2011 – Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, today unveiled the world premiere of “SUBARU BRZ CONCEPT - STI -” at the 2011 Los Angeles International Auto Show. (Press days on November 16 and 17. Open to public from November 18 to 27 in US)

The “SUBARU BRZ CONCEPT - STI -” is a concept car based on the “SUBARU BRZ”, an all-new rear-wheel drive (RWD) compact sports car developed from an ongoing joint-project between Subaru and Toyota Motor Corporation. By making full use of the Horizontally-Opposed Boxer, Subaru’s core technology, this concept car further pursued a "Pure Handling Delight" driving experience that can be realized by the Boxer engine’s low center of gravity. Combined with motifs of Subaru’s iconic performance brand “STI”, the concept car embodies an ultimate handling performance and symbolizes the possibilities the SUBARU BRZ holds for the future.

Styling

By installing the Boxer engine as low as possible, the low hood and sleek roofline together compose a sophisticated form. This is also blended with STI performance touches for a Subaru sporting profile.

A hexagonal lower front grille, hawk eye headlights and fin-shaped fog lamps make the front face instantly recognizable as Subaru.

STI-made lower front spoiler and rear wing magnify down-force and aerodynamics performance. They allow stable straight driving and excellent handling at high speeds.

The rear design with bold rear fender flares, large rear-diffuser, and twin dual tailpipes intensifies the STI performance feel.

A carbon-fiber roof, already installed in a WRX STI model and highly acclaimed, has been employed by the concept car. With it, extra weight reduction and an even lower center of gravity were achieved, contributing considerably to the ultimate handling performance this concept model aims to offer.

The lively exterior color “WR Blue Pearl II” is a new generation of the iconic WR blue paint scheme that

emphasizes the racing image.

Engine

The Boxer engine has inherent qualities of light weight, compactness, low center of gravity, and high rigidity – all pointing toward its great potential as a sports car engine. Taking full advantage of these features, a 2.0-liter horizontally-opposed four-cylinder direct fuel-injection gasoline engine has been developed exclusively for BRZ.

The engine has been designed with a square bore and stroke of 86 X 86 mm. Combined with Toyota’s D-4S direct injection technology (fuel injection system), high output and high environmental standards were both attained, both expected of a new generation sports car.

Chassis and Body

Compared with other Subaru models, the engine in SUBARU BRZ CONCEPT - STI - sits an impressive 120 mm lower and is positioned 240 mm closer to the center of the chassis. As a result, this car has achieved one of the lowest possible center of gravity in cars on the market today.

By incorporating lightweight parts such as a carbon-fiber roof, the overall weight has been reduced. Subaru has also succeeded in attaining a body structure that is both lightweight and highly rigid in a striking balance. The concept car is the embodiment of pure driving enjoyment only obtainable with a “Boxer sports car”.

Its unique handling performance has been remarkably refined by adopting STI’s lightweight 18-inch alloy wheels with performance tires and STI tuned suspension with excellent lateral stiffness.

Brembo brakes enhance braking performance.

Subaru BRZ Concept - STI to Debut at Los Angeles International Auto Show

-- First look at Subaru BRZ styling

-- STI-tuned chassis and carbon-fiber roof deliver the ultimate in handling and CoG

-- First RWD Subaru sports car

LOS ANGELES, Nov. 1, 2011 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.
