Mini does not build many cars like the Mini All4 Racing: a 3-door SUV with 3.0 L Turbodiesel I6, built from 2011 to 2016 as electrification stopped being an experiment and the crossover took every market.
Where it came from
The Mini All4 Racing is an off-road competition car, built by X-raid between 2011 and 2015, specially designed to take part in the rally raids with the main objective of winning the Dakar Rally. In 2017 Mini All4 Racing was succeeded by Mini John Cooper Works Rally.
Under the skin
Under the skin sits 3.0 L Turbodiesel I6. Kerb weight is 1900 kg. The gearbox is a 6-speed dual-clutch. The wheelbase is 2,900 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Mini's history is not in doubt: the Mini John Cooper Works Rally / Mini John Cooper Works Buggy followed it. On a showroom list of its day it stood against the Lexus LFA, the Nissan Leaf, the Jeep Grand Cherokee. Nearby in the Mini catalogue sit the MINI Beachcomber and the Mini (3rd Generation).
