What size engine is in the 2025 M5?

The 2025 BMW M5 is expected to feature a plug-in hybrid system combining a 4.4-liter V8 twin-turbo engine with an electric motor, boasting a combined output likely exceeding 700 horsepower and torque potentially breaking 800 Nm. This powertrain not only carries forward the M5's legacy of high performance but also improves fuel efficiency through electrification. Notably, this marks the first time the M5 has adopted a hybrid system, signaling the shift toward new energy in high-performance sedans—a trend mirrored in competitors like the Mercedes-AMG E63. For drivers who love behind-the-wheel thrills, the hybrid setup delivers more immediate torque response, while the electric motor should make low-speed acceleration feel sharper. These high-performance hybrid systems typically come with sophisticated all-wheel drive and adjustable suspension, ready to tackle everything from daily commutes to track days. If you're eyeing this class of performance cars, it's worth test-driving to feel the difference between hybrid and traditional gas-powered models—after all, the power delivery smoothness and exhaust note character will vary.
