There’s been talk for quite a while over at Subaru concerning the much-awaited reincarnation of the Subaru WRX STi. It was announced in 2011 that the venerable WRX trim for the Subaru Impreza would be split into it’s very own, purpose-build model, taking the STi along with it. However, Subaru has played it’s cards pretty close to the chest with regard to what the new WRX and STi will have in store for enthusiasts.
Subaru has seen some major changes over the past two years with the features of their vehicles, including it’s new direct injection 2.0 liter engine which incorporates Toyota’s DS-4 technology. This engine is currently being used in the new BRZ (as well as the Toyota 86 and Scion FR-S), and would likely be included in the new WRX, though it’s currently unclear as to whether the powerplant for the STi would be the traditional 2.5 liter that’s been found in the USDM model, outfitted with the new direct injection or the smaller-displacement 2.0l (additionally, Subaru has been looking into use of their FA-series 1.6l in the WRX, but that’s not set in stone). Fortunately, it’s looking like the 6-speed manual is going to stay in the STi models. It’s also rumored that the new STi will have upward of 320 crank horsepower.
There has also been talk of the inclusion of a new electronic turbo charger, which Subaru took out a patent on in 2007. The new electric turbo would remove the necessity for extensive turbo piping that’s been prevalent in previous WRXs. In addition, instant power-on-tap would help the car get up and go without the customary turbo lag.
Currently, it’s expected that the new incarnation of the STi will continued to be offered in a sedan, while the WRX will come in both hatch and sedan.
