Subaru’s BRZ Concept-STI (Subaru Tecnica International)
sports car has been unveiled at the 2011 Los Angeles Motor Show, ahead of the month-end reveal of the
production BRZ at Tokyo Motor Show.
The new rear-wheel drive compact sports car features a horizontally-opposed Boxer engine, enabling an
low centre of gravity – producing what Subaru describes as a “pure handling delight.”
The BRZ Concept–STI displayed in Los Angeles features styling cues developed by Subaru’s STI
performance division.
BRZ Concept–STI styling
The hexagonal lower front grille, hawk eye headlights and fin-shaped fog lamps make the front
instantly recognisable as a Subaru.
An STI-made lower front spoiler and rear wing magnify down-force and aerodynamic performance, while
aiding stable straight driving and excellent handling at high speeds.
The rear design, with bold wheel arch flares, large rear-diffuser and twin dual tailpipes,
intensifies the STI performance feel.
A carbon fibre roof is used – a highly acclaimed feature already installed in a WRX STI model in
Japan. This reduces weight and also contributes to the low centre of gravity and amazing handling.
The lively exterior colour is “WR Blue Pearl II” - a new generation of Subaru’s WR blue paint scheme,
emphasising the racing image.
Engine
The BRZ Concept–STI’s Subaru Boxer engine has qualities of light weight, compact size, low centre of
gravity, and high rigidity – all pointing toward its great potential in a sports car. The 2.0-litre
horizontally-opposed four-cylinder direct fuel-injection petrol engine has been developed specifically
for the 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
result.
Chassis and body
Compared to other Subaru models, the engine sits 120 mm lower and is positioned 240 mm closer to the
centre of the chassis. As a result, it achieves one of the lowest possible centres of gravity compared to
other cars on the market today.
By including lightweight parts such as the carbon fibre roof, the overall weight has been reduced. The
body structure is both lightweight and highly rigid.
Its unique handling performance has been refined by adopting STI’s lightweight 18-inch alloy wheels
with performance tyres and STI tuned suspension with excellent lateral stiffness.
Brembo brakes enhance braking performance.
