Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, has just unveiled the all-new WRX STI (US specifications) at the 2014 North American International Auto Show (NAIAS) currently being held in Detroit, Michigan.

As the top grade model of the WRX series, the new WRX STI embodies at an even higher level the shared product series concept: “Pure Power in Your Control”.

Starting with the base WRX model, Subaru has equipped the WRX STI with the powerful, motorsport-proven 2.5-liter Horizontally-Opposed turbo engine, an exclusively-tuned suspension for enhanced rigidity, multi-mode DCCD (Driver’s Control Center Differential) and more.

During development, Subaru honed the driveability of the new WRX STI to perfection, testing it under various driving conditions in several countries. As with past generations of the WRX STI, testing included ultra-high speed road testing on Germany's Nürburgring circuit, known for its harsh road conditions. Through this process, Subaru has raised performance for the body, chassis and other vehicle areas to the limit and fused them into one.

This has elevated overall vehicle performance, resulting in the pinnacle of Subaru AWD sport performance with predictable high power at the driver's fingertips.
