Understanding Volvo's Mild Hybrid Technology: Efficiency Without the Plug

Understanding Volvo's Mild Hybrid Technology: Efficiency Without the Plug

Volvo's mild hybrid system represents a smart middle ground between traditional engines and full electrification. This technology improves fuel efficiency and reduces emissions without requiring charging infrastructure or range planning—making it an ideal choice for Canadian drivers seeking better efficiency with familiar convenience.

Unlike plug-in hybrids or fully electric vehicles, mild hybrids use a small electric motor to assist the engine during specific driving conditions. The system operates seamlessly in the background, requiring no changes to your driving habits while delivering measurable benefits in real-world conditions.

How Mild Hybrid Technology Works

Volvo's mild hybrid system centers around a 48-volt electrical architecture that powers an Integrated Starter Generator (ISG). This component serves multiple functions throughout your drive.

During braking or coasting, the ISG captures energy that would normally be lost as heat. This recovered energy charges a compact lithium-ion battery mounted under the vehicle. When acceleration is needed, the stored energy assists the gasoline engine, reducing its workload and improving efficiency.

The system provides 13 hp of additional power during acceleration while delivering 40 Nm of supplementary torque. This assistance is most noticeable during city driving, where frequent stops and starts allow maximum energy recovery.

Real-World Benefits for Canadian Drivers


Mild hybrid technology delivers tangible improvements in daily driving situations common across Canada.

City Driving Efficiency: Stop-and-go traffic becomes more efficient as the system recovers energy during braking and assists during acceleration. The electric motor's instant torque provides smoother response from traffic lights.

Highway Cruising: During steady highway speeds, the mild hybrid system can briefly assist the engine during grade climbs or passing maneuvers, maintaining smooth power delivery without increasing fuel consumption.

Cold Weather Performance: The 48-volt system powers auxiliary equipment more efficiently than traditional 12-volt systems, reducing engine load during winter months when heaters, lights, and other systems draw significant power.

Available Across Multiple Models

Volvo incorporates mild hybrid technology across several 2025 models, each tailored to specific driving needs:

  • XC90 B6 AWD: 295 hp, 10.4 L/100km combined fuel economy 
  • XC60 B5 AWD: 247 hp, 9.0 L/100km combined fuel economy
  • V90 Cross Country B6 AWD: 295 hp, 9.5 L/100km combined fuel economy 
  • V60 Cross Country B5 AWD: 247 hp, 8.7 L/100km combined fuel economy

Each application maintains the familiar driving experience while delivering improved efficiency compared to conventional engines.

The Practical Choice

Mild hybrid technology removes common barriers associated with electrification. There's no need to install home charging equipment, plan routes around charging stations, or adjust to different refueling patterns. The system works transparently, providing benefits without requiring lifestyle changes.

For Canadian drivers covering long distances between cities or living in areas with limited charging infrastructure, mild hybrids offer an immediate path to reduced fuel consumption and emissions. The technology proves particularly effective in mixed driving conditions typical of Canadian commutes—combining city traffic with highway cruising.
