Subaru of America will add two limited-run variants under its STI performance line for 2018.
The 2018 WRX STI Type RA builds on the WRX STI’s 2.5-liter turbocharged boxer engine by adding a cold-air intake and high-flow performance exhaust, improving horsepower to an estimated 310, Subaru said.
The RA designation, standing for “record attempt,” is a nod to past Subaru performance models. The automaker hopes to set a speed record this summer with a race model dubbed the WRX STI Type RA NBR Special.
As an appearance upgrade, the Type RA adds a carbon fiber roof panel, a carbon fiber pedestal wing and 19-inch forged alloy wheels. It uses a Cherry Blossom Red accent around the grille and rear bumper cover.
