The side-to-side balance of the Subaru symmetrical drivetrain, combined with its compact layout and lower centre of gravity, give the WRX and WRX STI greater stability when accelerating, braking and cornering. What’s more, these two high performers see full-time power delivered to all four wheels when in motion. This is another important characteristic of the Subaru symmetrical full-time AWD system and a distinct advantage over on-demand AWD systems — as is incredible traction and more controlled performance on any road. The horizontally opposed design of the SUBARU BOXER engine lays the cylinders 180 degrees apart on each side of the crankshaft, creating superb rotational balance and reduced vibration. Its compact layout helps lower the centre of gravity of the entire vehicle, enhancing both stability and driving excitement. 7
