STI is the monastery of performance philosophy, a think tank of driving theory, a university of automotive principles. STI engineers tirelessly study, experiment, and test, in a never-ending quest to uncover the root fundamentals of performance.
We ask ourselves constantly: How are performance and confidence connected? What makes a car go faster? What makes a vehicle more enjoyable to drive?
We listen to racers and drivers. We use simulators, wind tunnels and tracks like the Nürburgring Nordschleife to put our engineering to the test. We drive in snow. We drive in mud. We drive in competition. All to create the ultimate automotive experience.
