Subaru 2015 WRX

After a seven-year run, the SUBARU 2015 WRX and STI have finally received a ground up redesign this year. Based on the latest Subaru Impreza, the WRX is a completely new animal and unlike the 2015 STI, uses no carryover parts from its predecessor.

New Turbo Engine under Hood

The biggest news is under the hood. Starting with the 2.0-liter turbocharged four-cylinder found in the Subaru Forester, the engine has been tweaked and strengthened for the WRX to make 268 hp and 258 lb-ft of torque. Although this is only a modest power bump, the extra torque is available from 2,000 rpm all the way up to 5,200 rpm. Peaking at 15.9 psi, the new 2.0-liter turbo can be run on regular gas or premium, but there is a minor power penalty when using regular.

Power delivery is smooth and constant. There are no dead zones present throughout the rpm range like were present in the old 2.5-liter turbo. Throttle tip-in for the WRX has been increased for 2015 as well, which only exaggerates how much more powerful the new engine feels. The exhaust we find is still too quiet and allows a less-then pleasant engine noise into the cabin under hard acceleration. A subdued exhaust note may be for the best however, since the new 2.0-liter set-up has eliminated the need for unequal length exhaust headers. Yes, that means the classic Subaru rumble will not be heard in the 2015 WRX.
