Subaru WRX: vroom, two different ways

Date:5 January 2014 Tags:,

Revving the engines of boy racers everywhere, Subaru’s new WRX made its world debut at the Los Angeles show.

Features include a new torque-vectoring system to reduce understeer, a new 197 kW 2,0-litre direct-injection turbo engine and either a standard 6-speed manual transmission or Sport Lineartronic CVT.

Subaru says the WRX engine, based on the engine of the new Forester 2.0 XT, uses a combination of direct fuel injection, high compression (10.6:1), Dual Active Valve Control System (D-AVCS), a twin-scroll turbocharger and an intercooler to produce 197 kW at 5 600 r/min. Its peak torque of 350 N.m is achieved from 2 000 to 5 200 r/min.

The new 6-speed manual transmission provides a wider ratio spread than the previous 5-speed and features some high-performance tech in this new offering from Subaru.

Two flavours of AWD.
Intriguingly, the WRX offers two versions of Subaru’s signature all-wheel drive. Models equipped with the 6-speed manual transmission use the Continuous AWD version of Symmetrical All-Wheel Drive, which has a viscous coupling locking centre differential.

This nominally distributes torque 50:50 front to rear. CVT versions get what’s called Variable Torque Distribution (VTD). A planetary gear-type centre differential and an electronically controlled hydraulic transfer clutch control torque distribution between the front and rear wheels. Under most conditions, VTD splits the torque 45:55 front to rear.
