More enjoyable experience on the road.

Subaru firmly believes that the Horizontally-Opposed Engine is the optimum design for driving enjoyment. The pistons face away from each other in a 180º...


Balanced & Composed.


The SUBARU BOXER engine, which powers every vehicle in the Subaru line, is renowned for its superior balance, smoothness and power delivery — and has been for 50 years now. This horizontally opposed design boasts a low centre of gravity...

Stability

Greater Stability for Easier Driving

  • Since the Horizontally-Opposed Engine is structured with the pistons mounted horizontally, it has a lower total height and is more compact and lighter than an in-line engine or a V engine. This allows for level cornering and more stable high-speed driving, thereby helping to realize the SUBARU ideal of enhanced driving safety.

Engine Movement

Enjoyable, Smooth Acceleration

  • The pistons in an in-line engine or a V engine generally move vertically. However, in the Horizontally-Opposed Engine, the opposed pistons move horizontally and the opposing forces cancel each other out, thereby reducing the amount of vibration and providing a more comfortable feel to the engine.

Safety

Cabin-protecting layout.

  • In the event of a head-on collision, the Subaru Boxer Engine and gearbox are designed to slide beneath the cabin for your protection.

Suspension system

Comfortable ride

  • Most sports cars make adjustments in the suspension system to ensure roll stiffness. In contrast, ultra-low center of gravity packaging has been achieved by pursuing the potential of the Boxer engine and the vehicle itself rather than unnecessarily tightening the suspension. This packaging makes it possible to enjoy excellent handling with little roll, instability, bumps and vibrations for a smooth and comfortable ride.

Motion and Steering Response

Advantages of shifting to a low center of gravity

  • Load shift reduces postural changes, making it possible to achieve both gentle motion and steering response. This ultra-low center of gravity packaging has achieved a gravitational center height of 460 mm*1, among the top class in the world*2. This provides drivers with handling that has excellent response and a comfortable ride for all. *1 In-house measurements *2 As of February 2012 (in-house research)

Steering Response

Handling with excellent response

  • Better contact with the road surface, little roll, and fast convergence afforded by a low center of gravity create a sensation of the vehicle adhering to the road. The excellent front and rear weight distribution of 53:47* produces a direct response to steering. The enjoyment of this completely new handling can be experienced not only in limited settings such as circuits, but by anybody driving on public highways or roads with even slight curves. This is the attraction of ultra-low center of gravity packaging. *In-house measurements

Various innovations

Achieving Comfort, Safety and Enjoyable Rides

  • ・The shapes of auxiliary equipment have been completely rethought to give the engine the lowest center of gravity possible. ・The driving position has been set at the lowest possible position to lower the center of gravity of the entire vehicle. ・A lightweight and highly rigid chassis has been specially designed to improve stability. ・Uses an FR layout and the pleasure of unembellished handling has been pursued to the utmost limit. ・A light yet strong body structure that ensures optimal performance for the front, rear and cabin has been developed.
