Subaru chose to take upgrades very slowly with the Subaru WRX STi and this has been a choice that they have come to regret, as it has given their competition time to catch up and possibly to get ahead.
When the Subaru WRX STi first came out it had an engine of 300 horses and since this time it hasn’t been treated to many upgrades. At the moment the vehicle offers 305 horses and this is just 5 more than what it offered some years ago.
The amount of horsepower isn’t all that bad but then you do have to take into account that there are rivals that offer a great deal more. For example the Ford RS offers up the 350 horsepower engine.
Subaru is hard at work on the new Subaru WRX STi and people want the 2018 version to come with a 2 litre 323 horsepower engine.
