Subaru Impreza WRX STi 'WR1'

Subaru’s fastest and most powerful Impreza ever – the WRX STi ‘WR1’ – is about to enter dealer showrooms, with more than half of the 500 limited run already spoken for.

The special edition Impreza WRX STi celebrates Petter Solberg winning the Driver’s Title in the 2003 World Rally Championship. It features a power upgrade to 320 PS plus a host of technical and visual upgrades and costs £29,995 on-the-road.

First unveiled in January at the ‘Autosport’ show, the Prodrive-developed ‘WR1’ has just received official Subaru (UK) engineering approval after recording the best performance figures ever for a road-going UK-spec Impreza.

Only 4.25 Seconds To Reach 60 mph

For example, 60 mph is reached in an astonishing 4.25 seconds with the 0-100 mph time at an equally impressive 10.67 seconds. Prodrive technicians also logged a quarter mile time of 12.8 seconds while the top speed is limited to 155 mph.

By comparison, the ‘standard’ 265 PS Impreza STi is quoted with a 0-60 mph time of 5.1 seconds and a top speed of 151.5 mph.

Peak power for the ‘WR1’ is 320 PS at a relatively low 5,800 rpm, with maximum torque or pulling power of 309.8 lb.ft at 4,000 rpm.

The ‘standard’ STi produces 265 PS at 6,000 rpm and 253 lb.ft torque at 4,000 rpm while the optional Prodrive-developed Performance Pack liberates 305 PS and 299 lb.ft torque at the same revs and reaches 60 mph in 4.6 seconds and 100 mph in 12.2 seconds.
