2020 Land Rover Defender: Everything We Know


2020 Land Rover Defender

Details have been scarce, but a new Land Rover Defender is coming. What we know so far is that it will come to the US and will likely share some components with other Jaguar Land Rover products. Even though the company is not releasing any details, here’s everything we’ve been able to glean from searches of engineer profiles on social media.

Tire Inflation

A new patent application from Jaguar Land Rover shows a central tire inflation system that could be destined for the new Defender. The patent application shows a very detailed system that interacts with various modules in the vehicle and adjusts tire pressures based on drive mode. The usual functions of a central tire inflation system are displayed, but JLR takes it a step further by integrating features such as a “Puncture Assist Mode.”

The features that are integrated into the drive modes appear to offer tire inflation for various environments and circumstances. The base or interim tire inflation pressure is set to 29 PSI and is adjusted based on the option selected. The example for the standard on road mode is set to 33 PSI in the front with 36 PSI in the rear. These pressures are very similar to what is listed on the placard for the current Land Rover Discovery, which is on the same platform that should underpin the Defender.

Going further into the various modes, we see that there is also a “High Load Mode” which pumps up the tires to over 40 PSI presumably to be able to take on extra weight. As expected, there are various examples of off-road modes which take the pressures down to a range between 20 and 26 PSI depending on the option that is selected. There is also a “Recovery Mode” which takes the pressures all the way down to 17 PSI which would likely be used to recover the vehicle out of sand or mud.

The integration of the system would allow it to work with the ABS and stability control modules so that the vehicle would be prevented from setting pressures out of range. In one example, the application states that the stability control module could communicate with the tire inflation module in order to prevent a situation where the vehicle would experience excessive oversteer or understeer.
