2019–2021 Land Rover Range Rover P400 MHEV Specs & Performance

The 2019–2021 Land Rover Range Rover P400 MHEV is part of the fourth-generation Range Rover (L405) and introduced a modern electrified approach to the model's petrol powertrain. Its 3.0-liter inline-six uses turbocharging, an electric supercharger, and a 48-volt mild-hybrid system to produce 395 hp and 406 lb-ft of torque. An eight-speed automatic transmission sends power to all four wheels, giving the P400 strong performance while adding electric assistance to a refined petrol powertrain.

The P400's significance lies in how Land Rover used electrification to supplement rather than replace the internal-combustion engine. The 48-volt system can recover energy during deceleration and support the engine during acceleration, while the electric supercharger helps build boost at low engine speeds. With a 5.9-second 0–60 mph time and 140-mph top speed, the P400 offers brisk performance for a full-size luxury SUV while retaining the L405's five-seat practicality, AWD capability, and long-distance comfort.
