What engine is in a Subaru WRX STI?
What’s the difference between a regular Subaru WRX and a Subaru WRX STI? Does the STI version have a more powerful engine, or is there something else that makes these two models different?
Liz Jenson · Updated on
Reviewed by Shannon Martin, Licensed Insurance Agent.
The engine in a
Subaru WRX STI
is a 2.5-liter turbocharged four-cylinder Subaru Boxer. With 310 horsepower, the WRX STI has a top speed of 174 mph.By contrast, the Subaru WRX maxes out at 155 mph with its turbocharged 2.4-liter flat-four-cylinder engine. So, if speed is your goal, the STI is the better option.
That said, the WRX STI is also significantly more expensive than the base WRX. If you want to upgrade to the STI for better performance specs, you’ll need to fork over an additional $14,000. If you’re not willing to pay that much more for an additional 20 mph, the WRX might be the right choice.
No matter which Subaru you choose, be sure to protect your car with great car insurance. The
