The Defender (L663, from 2020) is built on the D7x aluminum platform. It uses 2.0-liter Ingenium four-cylinder, 3.0-liter mild-hybrid inline-six and 5.0-liter supercharged V8 engines, plus a P400e plug-in hybrid, with an 8-speed automatic.
The 2020 Land Rover Defender belongs to the new Defender (L663) generation, built for model years 2020–2027. It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.
Check the model year on your VIN: on a 2020 vehicle the 10th character of the 17-digit VIN is “L”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 6 years old, a 2020 vehicle is usually past its basic warranty. Typical jobs at this age are brakes, suspension parts, fluids, the 12V battery and diagnosing sensor faults with the factory wiring diagrams.
