STI BRAND STI BRAND STI BRAND STI BRAND

STI is a comprehensive motorsports company, created to make Subaru the number 1 brand in the world. Based on the philosophy “safer driving by pushing the limits of performance,” Subaru is a Japanese automobile manufacturer in pursuit of the twin values, enjoyment and peace of mind.

Subaru vehicles are born with high performance. They combine AWD, which provides unsurpassed stability and the ability to drive on any road surface, with a bilaterally symmetric power train, which provides refined weight balance and contains a horizontally-opposed cylinder engine as its nucleus.
Through motorsport, STI proves the excellence and potential of Subaru vehicles.
STI’s challenge: Design and produce cars that blend human senses with the vehicle’s operation.
Regardless of who, how fast, or where, the car is like an extension of your body.
Comfort, we believe, is based on a foundation of peace of mind, afforded by safety. While driving, people unconsciously adjust for the subtle deviations between one’s own senses and the operation of the vehicle. From these deviations, fatigue builds up without us even realizing it. Fatigue leads to a decrease in awareness, concentration, and decision making skills.
Our customers are not machines, but people with feelings and emotions. Designing and producing vehicles focused on the senses and sensitivity of people—unable to be expressed in numbers or words—may not be rational.
However, we believe that the truth lies precisely in the parts we throw away when we think too rationally.
Answers given by a computer. Things written in a textbook. Things considered common sense in the world.
This is knowledge gained from history and built up by those who came before us.
But if we believe this to be true, and do not doubt it, all products will end up the same.
At STI, we have honed our skills through trial and error in real race conditions at the extremes of motorsports, grasped the essence of driving, and discovered our own path.
The car body flexes in harmony with your driving, providing strong yet supple performance.
Wild animals exhibit the same characteristics, giving credence to our approach. Through necessity governed by the laws of nature, strength and flexibility complement, not contradict, each other.

Trial and error through challenges and experience. A focus on the laws of nature. These provide knowledge not found in a textbook. The quest to push the limits of performance knows no end.
By making cars that blend with human feelings and respond to human sensitivity, we will continue the challenge.
