Prodrive brought their Subaru Impreza WRX “P25” to the Goodwood Festival of Speed. The unique project is powered by a turbocharged 2.5 L flat-four based on the EJ25. It features forged pistons, steel connecting rods, ported heads, Garrett turbocharger, and Akrapovič racing exhaust. The motor produces close to 450 hp (330 kW) and 600 Nm (442 lb-ft) of torque. The drivetrain comprises of an X-Shift six-speed sequential transmission, adjustable electronic center diff, and limited-slip differential in front and rear. The P25 uses a MacPherson strut front and rear suspension with custom billet aluminum uprights and Bilstein two-way adjustable coilovers. Braking is handled by AP Racing six-piston calipers with 380 mm vented rotors in front and four-piston calipers with 350 mm vented rotors in back. Covering those are Prodrive GC-012L 19×8.5-inch wheels with Bridgestone Potenza 235/35 tires. Watch the P25 race up Goodwood Hill in the video below.
