Subaru is continuing its tradition of introducing coveted special editions with the launch of the new Impreza WRX 300.

On sale from late May, the WRX 300 will feature a performance pack, developed by Banbury-based Prodrive, boosting power to 265 horsepower, giving a 0-60 mph time of 4.8 seconds and top speed in excess of 145 mph.

Finished in WR Blue, the all-wheel drive saloon boasts special 17-inch alloy wheels, an aluminium gearknob, WRX-branded carpet mats and a 'Subaru World Rally Team' logo on the front seats and front lamp covers.

Also included in the package is an RAC 'Trackstar' anti-theft device plus one-year's free membership.

This is in addition to a raft of improvements for the '05 Model Year WRX such as a revised chassis with inverted suspension struts and sharper-feeling steering for even more precise handling response.

Other changes for this year include enhanced interiors with plusher -- and extended -- cloth door trim, softer-feeling roof linings and a flush-fit centre console with new air-conditioning controls and new, quality-feeling switchgear.

Limited to 300 examples, the WRX 300 costs £21,495 on-the-road.
