NEW YORK - Subaru launches new STI Performance Concept, based off the BRZ.

• Concept showcases Subaru Tecnica International (STI) vehicle performance capabilities
• Concept features enhancements for chassis, body, and air intake/exhaust systems
• Concept’s engine is based on the racing engine from the Subaru BRZ Super GT race car

Subaru of America, Inc. today unveiled the STI Performance Concept at the New York International Auto Show. The STI Performance Concept signifies a plan for U.S.-expansion of Subaru Tecnica International (STI), the performance division of Subaru, in its three core business areas; aftermarket parts, STI-tuned cars and motorsports.

The expansion has already begun, with STI-engineered parts replacing Subaru Performance Tuning (SPT) aftermarket parts in the U.S. market, and with STI’s increasing engineering presence in Subaru of America’s Global RallyCross team. 

In the future, further models tuned by STI will be available in the US. These cars could feature more extensive modifications from the factory than previously offered, such as suspension, performance, braking, chassis and aerodynamic upgrades.

“At STI we know from our racing that to win, it is important not only to have high power, but also that all aspects of performance are balanced over the whole car,” said Yoshio Hirakawa, president of Subaru Tecnica International, Inc. 

“When we achieve this balance, the driver feels that the car is easy to handle and reliable, and he can use it fully to the limits of its performance. Our plan is to produce cars and accessories that drivers can really enjoy.”

The STI Performance Concept is a showcase for the engineering prowess and tuning capability of STI, featuring the racing engine developed by STI for the BRZ Super GT racecar, suspension and chassis components and aerodynamic upgrades.

Complete cars (extensive tuning by STI) and performance parts available now in Japan focus on the WRX STI, Forester and BRZ models. The Japanese domestic market uses the nomenclature “S model” as its naming for the WRX STI and uses “tS” on BRZ and Forester vehicles that have STI components, but a naming convention for any future US models has not yet been established.

STI was founded as Subaru parent company Fuji Heavy Industries’ motor sports division in 1988. In 1989, a first-generation Subaru Legacy, tuned by STI, broke the FIA-certified world speed record over 100,000 kilometers. 

From there, STI moved on to the World Rally Championship, winning 3 constructors championships and 3 driver championships for Colin McRae, Richard Burns and Petter Solberg. It currently competes in the Nurburgring 24 Hour Challenge race winning its class two times in 2011 and 2012 and also in the Super GT series with its BRZ-based Super GT.
