A Boxer engine is a hallmark of many Subaru vehicles, characterized by its horizontally opposed piston design. Unlike traditional in-line or V engines, the Boxer's pistons lie flat in two banks, which reciprocate in opposite directions. This unique configuration offers a lower center of gravity, leading to improved stability and handling. Subaru has leveraged the Boxer engine to enhance the performance and safety of its vehicles, capitalizing on its compact layout and balanced weight distribution. This architecture not only contributes to the distinct driving dynamics of Subaru cars but also aids in achieving a smoother and more efficient power delivery. The Boxer engine's design is integral to Subaru's identity, encapsulating their commitment to engineering vehicles that deliver both enjoyment and assurance on the road.
