Subaru kind of played it safe with the Subaru WRX STi when it comes to upgrades as they have been slow with them and this has allowed rivals to catch them up. Now there is the fear that they could end up being left behind.
The Subaru WRX STi came out with an engine of 300 horses and ever since this time it has been treated to few upgrades. The version on the market at the moment comes with an engine offering 305 horses and this means that it offers just 5 more than what it did years back.
The number of horses isn’t too bad of course but then you do have to consider the fact that the Ford RS does offer up 350 horses. Subaru is working on upgrades to the WRX STi and when it arrives in 2018 it is thought that it will come with a 2 litre turbocharged engine offering 323 horses.
