A forced induction system in that manner would eliminate the complicated turbocharger plumbing and that would result in more linear power delivery by greatly reducing turbo lag. Subaru has not said much about the system and instead they call it the latest of many rumours surrounding the next WRX and its STI variant.
There are also other many speculations about the next WRX and WRX STI. Firstly; it may feature smaller engines and if coupled with the electric turbocharger unit, it would have a better output in terms of fuel economy. Another thing is that the WRX cars could come with either a six-speed manual or a CVT unit.
I strongly believe that many Subaru fans would disapprove the idea of a CVT in a WRX. The term CVT and sports car just don’t sound and look right together. Maybe the company could invest in a dual-clutch unit instead. Anyway, it is clear that Subaru is distancing the WRX and WRX STI from the Impreza family tree and we will just have to wait and see what the future holds for the WRX.
