This is the proven strength, the heart and soul of the WRX STI's rally-bred genes. This evolution of the SUBARU BOXER 2.5-litre DOHC turbo engine* with large sized intercooler is the essence of what makes our FIA WRC experience count on the open road. There's an enormous 206kW (280 PS) of power, with a ground-breaking 392 Nm (40 kgfm) of torque. An Active Valve Control System, variable valve timing, semi-closed cylinder deck design, strengthened pistons, and secondary air system combustion all play their part, in providing outstanding performance that's also compliant with EURO4 emissions standards as well.

*This engine was voted Best 2-2.5-litre engine in the International Engine of the Year Awards 2006 , presented by UKIP Media & Events Automotive Magazines.
