The 2025 Volvo S90 presents a combination of refined engineering, modern powertrain options, and technology designed to enhance the driving experience. As a full-size luxury sedan, it offers both mild hybrid and plug-in hybrid configurations. These options deliver a balance of fuel efficiency, power output, and electric range tailored to contemporary driving needs. The 2025 Volvo S90 also integrates advanced safety systems and connectivity features that align with Volvo's reputation for innovation and occupant protection.
Engine Performance and Powertrain Options
The 2025 Volvo S90 offers two main powertrain options: the mild hybrid B6 AWD and the plug-in hybrid T8 AWD. Both utilize a 2.0-liter inline 4-cylinder turbocharged engine but differ significantly in output and electric integration.
The B6 AWD mild hybrid features an integrated starter generator and e-charger that assist the turbocharged engine to improve fuel economy and responsiveness. This setup produces 295 horsepower and 310 lb-ft of torque. Power is delivered through an 8-speed Geartronic automatic transmission, which includes adaptive shift and automatic start/stop technology. The all-wheel-drive system enhances traction in varied driving conditions, while the fuel economy rating stands at 22 miles per gallon in the city and 31 on the highway, with a combined rating of 25 mpg.
The T8 AWD plug-in hybrid adds an electric motor to the internal combustion engine, resulting in a combined system output of 455 horsepower and 523 lb-ft of torque. The gasoline engine generates 312 horsepower and 295 lb-ft of torque, while the electric motor contributes 143 horsepower and 228 lb-ft of torque. This configuration supports an EPA-rated pure electric range of approximately 38 miles, allowing for short trips on electric power alone. The combined fuel efficiency measures 66 MPGe, reflecting the integration of electric and fuel power. The transmission and all-wheel-drive system mirror those of the B6 AWD model, ensuring smooth shifts and stability.
Disclaimer: * EPA estimated range is 23 MPG city/31 MPG highway/26 MPG combined. Your actual range will vary for many reasons, including but not limited to, driving conditions, how and where you drive, how you maintain your vehicle, battery-package/condition, and other factors.

Both powertrains maintain a cargo capacity of 13.5 cubic feet, preserving practical storage space despite the hybrid components.
