Prodrive’s P25 Subaru Impreza with a Turbo 2.5 L Flat-Four

It’s been 25 years since Prodrive debuted their two-door WRC Impreza. They are celebrating this milestone by building 25 anniversary cars called “P25” based on an original two-door Impreza WRX chassis. Under the hood sits a turbocharged 2.5 L flat-four producing 400 hp and 600 Nm (442 lb-ft) of torque. The engine features Prodrive’s custom pistons, rods, and heads. That is paired with a X-Shift six-speed sequential transmission, adjustable center differential, and limited slip diffs front and rear. The P25 rides on a MacPherson strut front and rear suspension with custom billet aluminum uprights and Bilstein two-way adjustable coilovers. A set of Bridgestone 19-inch wheels cover AP Racing six-piston calipers with 380 mm vented rotors in front and four-piston calipers with 350 mm vented rotors in back.
