Super TestCar reviews - Subaru - Impreza - WRX STi sedanSubaru modelsTransmission22 May 2002 THE STi is only available with Subaru's new six-speed manual transmission, which has a close ratio gear set and shorter shift mechanism. The transmission is fitted with significantly larger gears - increased gear diameter and thickness - than the WRX's five-speed manual for added strength and durability. Bearing size has also been increased to cope with the engine's higher power output. Double cone synchromesh mechanisms are used on first, third and reverse gears, while second gear features a triple cone synchroniser to deal with the punishment of quick first to second gear changes under hard acceleration. The transmission case is no longer a split half arrangement, instead it is now of a single unit construction. Did you know?The STi's high performance clutch has a single plate diaphragm with increased clamping load of 930kg, compared to the 830kg of the standard Impreza WRXAll car reviewsAlfa Romeo Abarth Alpine Alpina Audi Aston Martin BMW Bentley Chevrolet Chery Citroen Chrysler Dodge Cupra Ferrari DS Ford Fiat FPV Foton GWM Great Wall Holden Haval HSV Honda Hyundai Hummer Isuzu Infiniti Jeep Jaguar Lamborghini Kia LDV Land Rover Lotus Lexus Maserati Mahindra McLaren Mazda Mercedes-Benz Mercedes-AMG Mini MG Nissan Mitsubishi Peugeot Opel Proton Porsche Renault Ram Rover Rolls-Royce Skoda Saab SsangYong Smart Suzuki Subaru Toyota Tesla Volvo Volkswagen |
