Why Subaru Engines Stand Out

Subaru is renowned for its Boxer engine layout — horizontally opposed piston engine with better balance, lowered center of gravity, and better smoothness. This is not just clever engineering for engineering’s sake — part of the reason why Subarus are so renowned for snow, gravel, rally rallying, and everyday driving.

Subaru engines are:

  • Efficient – Because they are small and naturally balanced
  • Long-lasting – Constructed to endure the distance with best-quality components and tight tolerances
  • Powerful – Especially the ones with turbocharging
  • Dependable – Tremendous popularity among mechanics and Subaru drivers worldwide
