Other test track statistics see the ‘WR1’ shaving 0.7 seconds off the STi’s 30-50 mph time in 4th gear – down to 4.0 seconds – and 0.8 seconds off the 50-70 mph time in 5th – now 4.6 seconds.
Finally, illustrating its supercar-like performance, the new ‘WR1’ boasts an 80-100 mph time of a staggering 3.6 seconds in 4th gear and 6.5 seconds in 6th (4.6 and 7.8 seconds for the 265 PS STi).
The ‘WR1’s extra power and torque are achieved thanks to a revised engine control unit (ECU), high-flow catalyst and sports silencer.
Driver-Selected Torque Split Tailors Handling Balance
Also guaranteed to excite enthusiasts is a driver’s control centre-differential (DCCD) via a switch mounted next to the handbrake.
It means the torque distribution between front and rear wheels can be manually selected. This allows the choice, for example, between a sharper cornering turn-in or more stable straight-line running. The system defaults to ‘automatic’ mode whenever the ignition is restarted.
Also new for the ‘WR1’ are special, Prodrive-developed uprated springs and bump-stops with a 25 mm lower ride-height.
Special Wheels, Body Colour And Interior
Other handling-enhancing features include 18 ins diameter P-FF7 (Prodrive Flow Forming seven-spoke) alloy wheels with 225/45 Pirelli PZero tyres.
Externally, the new ‘WR1’ is instantly recognisable thanks to its new Ice Blue Metallic paint plus driving lamps and a stainless steel mesh grille.
Interior changes include anthracite instead of blue suede-effect seats, a special gear knob, imaged carpet mats and a tax disc holder engraved with the special edition number.
Features shared with all Impreza WRX STi’s range from a six-speed gearbox to Brembo brakes and front and rear ‘Suretrac’ differentials.
