Subaru chose to play it safe with the Subaru WRX STi and this is something that they have found to be a mistake as it has allowed competitors to catch up with them. It may even mean that they are the ones that end up getting left behind.
When the Subaru WRX STi was first launched it offered the 300 horsepower engine and since this time there have been few upgrades to it. The version of the vehicle that is on the roads at the moment only offers 5 horses more than years ago, so this hasn’t been much of an upgrade at all.
The amount of horses isn’t bad, its just that Subaru are falling behind as rivals are now offering more power. The Ford RS for instance is offering the 350 horsepower engine.
Subaru is working on the 2018 Subaru WRX STi and people really want the vehicle to come with an upgraded engine. They are hoping that it will be the 2 litre 232 turbocharged engine.
