It’s not a big addition, and it’s not confirmed yet, but more power is always welcome.
Everyone knows motorsports stickers automatically add 5 horsepower to whatever car they are placed on. For 2019, however, Subaru WRX STI owners might be able to skip the stickers and get some extra hustle straight from the factory — something that’s long overdue.
According to The Truth About Cars, next year’s rally-car-for-the-road will get a bump of 5 horsepower, to 310, from its turbocharged 2.5-liter H4. That’s the same power output as the limited-edition STI Type RA. Whether or not the plain ol’ STI will get other goodies found on the Type RA like Bilstein shocks, a carbon fiber roof and a tuned ECU remain to be seen, but it’s not too likely.
The lower-level WRX with its 2.0-liter turbo H4 will remain the same at 268 horsepower. Then again, the WRX hasn’t been sitting at exactly the same power output for the better part of an entire decade, so it makes sense that the STI would be first in line for a massage.
Subaru neither confirmed nor denied the rumor to TTAC, but we’re praying it’s true. While 5 horsepower might not seem like a lot, it can make a big difference in the enthusiast world where folks fight for every tenth of a second on the track.
