Subaru will launch a new special edition Impreza WRX STI in memory of rally hero Richard Burns who died of cancer in November 2005.

The RB320 features £6,000 worth of extra equipment including the 320 PS Prodrive performance pack (PPP) and will be priced at £29,995 on-the-road when it his UK roads in spring.

Available only in Obsidian Black, the RB320 features 18-inch alloy wheels and specially developed Prodrive suspension comprising Bilstein dampers, a sports spring kit with revised rear anti-roll bar and a lowered ride height.

Also standard on the RB320 is a chrome mesh front grille, front lip spoiler, quickshift gearchange, side sill plates and RB320-branded gear knob, carpet mats and exterior badging. Each owner will also receive an individually numbered black alloy tax disc holder.

The PPP boosts power to 318bhp and reduces the 0-60 mph time to 4.8 seconds.

Customers placing early orders with deposits will be offered a limited number of places at a special RB320 launch event next March at Prodrive’s test track in Warwickshire.

The first RB320 is to be given away in a raffle organised by Autosport magazine, donated by Subaru UK. The proceeds will go to the Richard Burns Foundation which helps those suffering from serious injury and illness.
