2006 Subaru Impreza WRX STi RB320
21 November 2006 – Subaru UK has announced a new special edition Impreza WRX STI in memory of rally hero Richard Burns who died in November last year of cancer.
Called the RB320, the new car features around – 6,000 worth of extra equipment including the 316 bhp (235 kW) Prodrive Performance Pack, yet costs 57 900 USD (29,995 GBP) on-the-road.
Available only in Obsidian Black, the RB320 features bespoke 18 ins alloy wheels and specially developed Prodrive suspension comprising Bilstein dampers, a sports spring kit with revised rear anti-roll bar and a ride height lowered by 30 mm at the front and 10 mm at the rear.
Also standard on the RB320 are a chrome mesh front grille, front lip spoiler, quickshift gearchange, side sill plates and RB320-branded gear knob, carpet mats and exclusive exterior badging. Each owner will also receive an individually numbered black alloy tax disc holder.
The PPP boosts power to 316 bhp (235 kW) at 6,000 rpm with torque leaping to 332 lbft (450 nm) at 3,700 rpm. This reduces the 0-60 mph time to 4.8 seconds with a 0-100 mph time of 12.2 seconds.
And as a further incentive, those 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.
Not only will RB320 fans take delivery of their cars at the circuit but will be able to drive demonstration STIs around the track and meet rally celebrities.
In addition, customers will also be able to register on-line and reserve the limited-edition number of their choice via a special sub-section of Subaru’s website.
Finally, the first car is to be given away in a special raffle organised by Autosport magazine, donated by Subaru (UK) Limited.
The proceeds will go to the Richard Burns Foundation which helps those suffering from serious injury and illness.
