The 2015 Subaru WRX STI has been unveiled at the North American International Auto Show in Detroit. This is the first time the public has been able to get a glimpse of the new performance icon.

2015 Subaru WRX STI

Based on the recently revealed 2015 WRX, the car on display is actually a US-spec version however most of the design and exterior features will be used for international models.

We suppose the first thing you want to know is what engine it comes with? Subaru has decided to stick with the 2.5-litre turbocharged flat four instead of boosting the new 2.0-litre.

In the US-spec version it produces 227kW of power at 6000rpm and 392Nm of torque at 4000rpm. This makes it 6kW more powerful than the outgoing model, however, torque drops from 407Nm.

Countering previous rumours, Subaru is matching the engine up with a six-speed manual transmission. It is a revised unit with multi-mode DCCD controls for the centre differential, while active torque vectoring is also added for the first time.

As for the distinctions, the new STI features a longer wheelbase by 25mm for more rear legroom, the bottom of the A-pillars are extended by 200mm, and the side mirrors are mounted on the doors with a new quarter window added in.

There’s also of course a full bodykit with an aggressive front end and front spoiler system, side skirts, and a large rear wing. Subaru says the new body is lighter weight than the outgoing version, although figures haven’t been mentioned.

The new model will go on sale in Australia later this year with local specs and prices yet to be announced. See below for some of the specifications.

  1. ‘This makes it 6kW more powerful and 42Nm more torquey than the outgoing model.’

    I love your content, but the previous model in australia has 221kw/407nm not that numbers matter really… the 42nm part is incorrect lol

    damn it subaru why use the ej25t, why not the fa20 which has peak torque at 2000 and turbo huffs to 6700 rpm like the 2015 wrx has, regular wrx will be better i bet, what is the point of the sti lol, may as well whack brembos onto regular wrx lol and if you wanted a stronger trans get the sti trans on the regular wrx lol
