Subaru WRX STI (2014–2018)
WRX STi unveiled
Subaru UK confirmed arrival of new WRX STI in September 2014. No longer prefixed Impreza new WRX priced at a highly competitive £28,995, £4,000 less than the previous car due to the fall of the Yen, with orders accepted from May 2014.
During development, Subaru honed the driveability of the new WRX STI to perfection, testing it under a wide variety of conditions around the world. As with past generations of the model, extensive testing also took place on Germany's Nürburgring circuit to ensure the WRX STI is the pinnacle of Subaru AWD sports performance.
At its heart is a 2.5 litre turbo-charged Subaru Boxer four-pot engine, which in STI guise, produces 305PS and 407Nm of torque. The six-speed gearbox has been reinforced and now adopts even shorter throw and slicker, sportier shift feel.
Subaru’s trademark Symmetrical All-Wheel Drive employs the latest vehicle dynamics control (VDC) and Active Torque Vectoring for maximum control and driver engagement. Spring and damper rates have been meticulously re-tuned to provide a more compliant ride while retaining body composure, and the electronic power steering is now mounted on a more rigid steering gearbox mount for improved fuel efficiency and more ‘direct’ feel and response.
An increase in wheelbase of 25mm gives the new WRX STI greater rear leg room as well as more shoulder and elbow room inside the cabin, without increasing the exterior dimensions. By moving the bottom of the A-pillars forward by 200mm and adding a quarter light to the front window, drivers have better visibility all round. Boot space is increased and ingress and egress are improved with larger door apertures.
A lot of work has also gone into improving the perceived quality of the WRX STI interior. For the new model, highlights include a new D-shaped steering wheel of smaller diameter and designed to give the driver maximum feel. Soft touch materials are used in key areas while new dials and carbon effect and metal trim is also employed to give the STI both a suitably sporty feel and more upmarket ambience.
UK buyers can expect a comprehensive standard spec, in addition to changes over the WRX on the exterior design including the large signature rear wing and larger diameter wheels. At the rear, the diffuser integrated bumper and twin dual mufflers are unmistakably Subaru while new 18in. alloy wheels are designed to be both lighter and more rigid. LED lighting is employed for the headlights, tail and brake lights while ‘STI’ badges are found on the front grille and wings.
