305 PS Prodrive-Developed Performance Pack Continues
A popular option - the 305 PS Prodrive-developed performance pack - continues to be available for the ’05 Impreza STi.
Costing £1,995 including 2.5 hours for dealer fitment, the power upgrade also sees torque leap to 299 lb ft. This results in a 0-60 mph time of 4.6 seconds, a 0-100 mph time of 12.2 seconds and a top speed exceeding 155 mph.
As with the normal WRX, the horizontally-opposed four-cam, 16-valve ‘boxer’ engine has a bore and stroke of 92x75 mm for a capacity of 1,994 cc and runs on an 8.0:1 compression ratio.
Fast cars need good brakes and the STi features an ABS braking system made by renowned specialists, Brembo S.p.A of Italy while a close-ratio six-speed gearbox exploits the engine’s performance to the full.
All Imprezas marketed by Subaru (UK) Limited come with the reassurance of a three year or 60,000 mile warranty plus 12 year anti-corrosion cover and three year paintwork warranty.
This is in addition to three years’ membership of Subaru Assistance - a comprehensive home and roadside repair and recovery package throughout the UK and Europe administered by Mondial Assistance.Published 17 September 2004
