BMW V8 Engines in Land Rover Range Rover – N63B44E vs S68B44B

For flagship performance, Land Rover equips its top Range Rover (L460) and Range Rover Sport (L461) models with BMW 4.4L twin-turbo V8 engines, delivering exceptional power and refinement. Two main variants have been used: the N63B44E (2021–2024) and the updated S68B44B (2025+) with 48V mild hybrid.

The N63B44E powered the Range Rover P530 and P615 SV from 2021 to 2024. It produces 530 hp (390 kW) and 750 N·m of torque, with a 0–60 mph time of 4.4 seconds. This twin-turbo V8 features a “hot-vee” design, with turbos mounted in the V-angle for faster response and reduced heat loss. It’s a pure gasoline engine, no hybrid system, delivering linear power and a distinctive V8 exhaust note. For 2025+, Land Rover upgraded to the S68B44B, adding a 48V MHEV system for improved efficiency and responsiveness. While maintaining the same 530 hp output, the S68’s hybrid system provides electric torque assist at low RPM, reducing turbo lag and improving fuel economy. It also enables smoother stop-start and energy recovery, making it compliant with stricter Euro 7 emissions rules. A key difference is compatibility: the N63B44E fits 2021–2024 L460/L461 models, while the S68B44B is exclusive to 2025+ vehicles due to electrical and ECU changes. Both engines use an 8-speed ZF automatic transmission and Land Rover’s full-time 4WD, ensuring precise power delivery on and off-road.

In summary, the BMW V8 partnership gives Land Rover’s flagship models uncompromising performance. The N63B44E offers classic V8 power, while the S68B44B adds hybrid efficiency—both defining the pinnacle of Range Rover luxury and capability.
