New Range Rover L460, L461 factory power upgrade Plug-in Hybrid 3.0 Petrol from P440e to P510e.

In this article, we will discuss the hybrid version of the 3.0-liter inline petrol engine with P440e and P510e versions, which appeared with the release of the new Range Rover L460 and Range Rover Sport L461. We have discussed in detail how factory power upgrades work in a previous article https://www.lr-chip.co.uk, so we will not repeat ourselves and get straight to the point.

Our regular client contacted us with a request to explore the possibility of replacing the engine control unit software from P440e to P510e. Yes, our client would have gladly purchased the more powerful Range Rover P510e directly from the factory, but unfortunately, such versions are not currently available, and the waiting times are too long. Before starting any software works, we carefully studied the two versions of the Range Rover P440e and P510e. We compared the powertrains, engine components (boost system, fuel system, cooling system, intake system, and exhaust system), transmission, differentials, drives, and the hybrid electric system (battery, charging system, inverter, etc.). All these studies confirmed our suspicions that these vehicle versions are produced in a single technical configuration and that the difference between them lies in the engine control unit software.

Let’s look at the technical specifications of these versions, as stated by the vehicle manufacturer:

P440e – 440ps/620Nm
0 to 100 km/h – 6.0s

P510e – 510ps/700Nm
0 to 100 km/h – 5.5s

Both versions have quite impressive factory acceleration dynamics, which are enhanced by the additional electric installation. The weather conditions were not ideal for measurements, but our main task is to understand the difference between the acceleration dynamics of the two factory versions under real conditions. The measurement was taken at idle, in standard city mode (comfort mode), with two people in the vehicle.

First, before starting factory chip-tuning, we measured the initial acceleration dynamics of the Range Rover P440e. We got a 0-100 km/h result of 7.4s. It slightly different from the factory-stated data, but it is expected under our measurement conditions.

Then we drove to our workshop to carry out software power upgrade works.

Upon completion of the work, we immediately went on a test drive and subsequent acceleration measurements. After leaving the workshop and a full test drive in various modes, the client reported that they felt a significant, positive difference in the vehicle’s behavior and dynamics. All that remained was to support the sensations with 0-100 km/h acceleration measurements.

The client’s sensations did not disappoint, under the same conditions, the vehicle accelerated 0-100 km/h 1 second faster, reducing acceleration time from 7.4s to 6.4s. This is an excellent result for a vehicle with such dimensions and a 3.0-liter petrol engine.
