Subaru WRX a show stopper
Subaru have unveiled the 2015 Subaru WRX, a more powerful and better-handling version of the brand's iconic high-performance model, at the Los Angeles Auto Show.
Powered by a new 197 kW 2.0-litre direct-injection turbo (DIT) Boxer engine, the 2015 WRX debuts the model’s first six-speed manual transmission and a new, optional performance automatic transmission – Sport Lineartronic CVT with two manual modes.
For 2015, the Subaru WRX employs a new torque-vectoring system that supplements the standard Symmetrical All-Wheel Drive system. Torque vectoring allows for improved cornering speeds and handling. The new and stiffer chassis, larger brakes, performance-tuned suspension and a driver-focused interior remain integral to the WRX performance character.
At the same time, a roomier interior, upgraded cabin comfort and materials and a wide array of new user technologies give the new WRX a more refined feel. A harman/kardon premium audio system is also offered for the first time in a WRX.
The new WRX features a much bolder front design with a deep front spoiler and unique grille. The wide-body stance seen on the previous model is enhanced with new, standard 17-inch wheels. The bonnet, front fenders, rear doors and fenders, bumpers, headlights and taillight clusters are all unique to the 2015 WRX. Specially designed for the 2015 WRX, the rear doors and fenders continue the model’s wide-body stance in a rakish new profile.
Other new performance-oriented details include fog light surrounds with a carbon fibre-like pattern and vertical front fender vents which feature chrome garnish and a mesh screen. Higher-grade models use new LED low-beam headlights; halogen lights are used on other models. The side sill spoilers that help to visually lower the car also help protect the doors from stone chips.
The new WRX body structure makes greater use of high-tensile steel than the previous model and features special stiffening elements at key locations. Combined with the new electronic power steering system, specially tuned suspension and 235/45 R17 94W Dunlop SP Sport Maxx RT tires, the stiffer chassis yields steering response that was benchmarked against top-handling sports cars.
The new WRX 2.0-litre, 4-cylinder boxer engine uses a combination of direct fuel injection, high compression (10.6:1), Subaru Dual Active Valve Control System (D-AVCS), a twin-scroll turbocharger and an intercooler to achieve its performance. The engine produces 197 kW at 5 600 rpm, accompanied by a broad torque curve that peaks at 350 Nm over a 2 000-5 200 rpm engine speed range.
Based on the engine used in the new Forester 2.0 XT, the WRX version uses different cams and higher-rate valve springs, among other enhancements, to extend the performance envelope. The new 6-speed manual transmission provides a wider ratio spread than the previous 5-speed and incorporates several performance and durability improvements for this high-performance application, including carbon synchronisers on first and second gears.
The all-new Subaru WRX is due for South African introduction towards the middle of 2014. Specifications may differ from the US version.
