It is significant for being the first all-new version of the Defender, breaking the engineering lineage with its predecessor, a descendant of the original Series Land Rovers of 1948.

The cars are built in Slovakia at Jaguar Land Rover's Nitra plant,[3] a manufacturing facility which opened on 25 October 2018.

[4] The car, which shares no components or technology with its predecessor Defender model, has permanent all-wheel drive, locking differentials in the centre and rear, and a two-speed transfer case.

[9] "Combine (its) seemingly impossible blend of qualities with a fantastic looking package inside and out and you have a vehicle that is literally like no other".

For the 2021 model year (announced September 2020), the following JLR Ingenium in-line 6-cylinder diesel engines with mild hybrid technology are available: D200, D250, D300.

[17] The Defender is available in Standard, S, SE, XS, HSE, X, V8 and V8 Carpathian Edition trim lines.

The entry-level 110 models will come equipped with air suspension, 18-inch steel wheels, LED headlights, and a 10.0-inch touchscreen infotainment system.

The car debuts Jaguar Land Rover's Pivi Pro infotainment system, accessed through a 10-inch touch screen.

There are also Hard Top or Commercial versions of both the 90 and 110 variants, in a number of different trim levels, available as Euro N1 vehicles, fully VAT deductible, in the UK and other markets.

The Bond Edition Defender used a 518 Horsepower 5.0 Litre supercharged V8 and utilised the same gearbox as the standard V8 model.

The infotainment system was fitted with a custom startup screen to commemorate Land Rover's long lasting relations with the Bond franchise.

The Land Rover Defender 75th Anniversary Edition[21] is a modified variant of the 2020 Defender with all Grasmere green paint (as a nod to the original 1948 HUE 166, 1st production Land Rover), for both the main body, wheels and interior cross beam.

[22] Limited to 20 units, as depicted on the tailgate, the Beach Break Edition adds a red and orange striped side decal similar to that of the Defender Country Pack.

It comes standard with cross bars, side-mounted storage pod, black fixed side steps and mud flaps.

Additionally, the Defender OCTA includes hydraulically-interlinked 6D Dynamics Suspension technology, also featured on the Range Rover Sport SV.

[30] This system allows the Defender OCTA more wheel articulation off-road, while also reducing body-roll on road.

Redesigned grilles and the signature Defender OCTA octagon logo are present around the car.
