SUBARU IMPREZA WRX & STi Features
Subaru's Horizontally-opposed engine gives the Impreza WRX a low center of gravity and good front-rear and lateral weight distribution.
The Impreza WRX's 4WD system consists of a perfect linear alignment for its light weight and compact BOXER engine, transmission, propeller shafts and rear differential. This ideal layout creates outstanding left-right and front-rear weight balance so it is the perfect 4WD system.
So as a result, the performance has improved every year. |
