This is going to be an important question for potential buyers because Subaru WRX STI running costs are high. Fuel economy is a claimed 27.2mpg on the combined fuel economy cycle, but during our test we just about nudged 21mpg. That's almost half as efficient as a Golf R's claimed economy, yet it's not as quick in a straight line. You're really going to have to want this car.



Car tax is going to be rather high indeed too; CO2 emissions are a massive 272g/km so VED is going to be significant, and don't even ask about company car tax.

Service intervals of one year or 10,000 miles aren't the shortest we've heard of, but it's worth remembering that'll need financial attention too. Also, where is your local Subaru dealer? They're popping up regularly, but the nation isn't exactly saturated with them yet.

Subaru WRX STI emissions aren't great. In fact, they're higher than a Porsche 911 Turbo S, which covers 0-62mph in just 3.1 seconds. You can see that Subaru has somewhat fallen behind in this respect.



This car really does feel like it's going to stand the test of time. In fact, we're pretty confident about Subaru WRX STI reliability. The firm has a reputation for seriously well screwed-together machines that go on for years, and we've seen nothing so far to indicate this car will be any different.



There haven't been any recalls of any version of the STI, and we've not come across any issues reported by owners either.

How much is it to insure?

Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.
