Subaru WRX STI 340R

UK only Subaru WRX STI 340R is mouth watering

The Subaru WRX STI is already a rocket on wheels, but in the UK, the high-performance car now comes as a 340R with even more horsepower and torque.

Subaru has just announced the WRX STI in the UK will offer a new performance power upgrade called the 340R that will make the high-performance model insanely fast. The new 340R engine upgrade has been added to the lineup and will be available alongside the 320R that was introduced last year. The 320R offers an already healthy 315 horsepower, but the new high-performance 340R will produce 335 horsepower and 361 lb. ft. of torque.

When you put the new UK model along side the U.S. version, you begin to see that the Brits get an unfair advantage. The North American WRX STI comes with 305 horsepower and 290 lb. ft. of torque which is a big difference in power output. While aftermarket kits are available in the U.S. to achieve those numbers, the factory UK upgrades can be added without affecting the car’s warranty.

Subaru has increased performance in the 2.5-liter boxer engine by using different ECU settings. The high-performance 340R also gets an increase in airflow through a new high-flow exhaust system which also provides drivers “with a thrilling soundtrack and the iconic Subaru burble.”
