Why Volvo have no compression?

Volvo engines are designed with a focus on safety, efficiency, and environmental concerns, which sometimes leads to lower compression ratiOS compared to performance-oriented engines. Lower compression can reduce the risk of knocking and allows for the use of lower-octane fuels, making vehicles more accessible and economical to operate. Additionally, turbocharging in many Volvo models compensates for lower compression by providing better power output without compromising efficiency.
