D200 • D250 • D300 → D350 Power Upgrade: Everything You Need to Know
Land Rover’s 3.0L Ingenium diesel engines—D200, D250, D300, and D350—share the same hardware.
The differences come from software calibrations controlling boost, torque limits, injection maps, and thermal strategy. Because the engines are mechanically identical, D200/D250/D300 models can be upgraded safely to full D350 output using OEM-level programming.
This upgrade improves acceleration, towing, throttle response, and overall drivability across Defender, Discovery, and Range Rover models.
