After a long period of teasing photos and the like, Subaru has finally announced the specification of the Impreza WRX STI, which will go on sale in the UK next spring.
The familiar 2.5-litre flat-four turbo petrol engine has been given a good seeing-to, including the introduction of a larger intercooler, and now produces 296bhp. The SI-Drive system from the Legacy 3.0R Spec.B has been carried over, so the new STI has a choice of three modes of throttle response, though none of them affects the behaviour of the engine itself.
There's four-wheel drive, of course, and a six-speed manual gearbox which is claimed to have a better shift quality thanks to revised synchromesh. As with the previous STI, this one has a driver-controlled centre differential, but it's been developed to give four different types of torque distribution between the front and rear axles. Three of these are automatic, while the fourth is manually adjustable.
Another feature brought along from the old STI is an inverted front strut set-up designed to reduce camber change during hard cornering. The lower arms on the front suspension are made of aluminium to reduce weight, Brembo brakes are fitted all round, and the centre of gravity is even lower than on the previous car thanks to lower mounting of the engine.
UK prices will be confirmed later.
