The limited edition is named after the Rally GB – Subaru’s most successful WRC stage – and the 270 hp the Prodrive-uprated engine produces.
Both models benefit from the 270 hp Prodrive Performance Pack which boosts power by 40 hp and torque by a staggering 74 lb ft to 310 lb ft. The result is a 0-60 mph time reduced from 5.9 to 5.3 seconds and a 0-100 mph time of 13.9 instead of 14.4 seconds. Mid-range response is substantially improved. Other shared features include a lowered spring kit, ‘quickshift’ gearchange, special carpet mats, MOMO ‘Air-Race’ gear knob, larger-diameter 18x7.5ins GT1 alloy wheels and GB270 exterior badging and individually numbered interior plaque.
Specific to the Impreza GB270 saloon are a WRC-style rear spoiler, stainless-steel mesh front grille, STI front lip spoiler and silver-finished alloy wheels.
Helping the GB270 Sports Wagon stand out is a rear waist spoiler, front and rear aero splash guards, rear privacy glass, black stainless-steel mesh front grille and gloss-black alloy wheels.
In addition, both models will be available with an optional ICE pack consisting of a Clarion SatNav and iPod adaptor and Bluetooth ’phone kit for £1,750. Other extra-cost upgrades include a GB270-branded leather or Alcantara/leather interior for £1,400 or £1,600 respectively and privacy glass window tinting for the saloon at £405 (all prices include VAT). A totally new 5-door Impreza will be launched in the autumn in 1.5 and 2.0 litre naturally-aspirated versions only. The turbocharged STI returns in the spring.
