Proof, in case you need it, that Land Rover is a very serious off-roading company.
When you consider the serious amount of luxury heaped all over the Range Rover, it can be almost surprising that the Defender, a seriously hardcore off-road machine, could be made by the same company. It is an extreme form of utilitarian, and the ones you'll see in this video are the most extreme of all. The cars are shown here competing in off-road time trials. It's not a big international contest with big sponsorship money, but rather a friendly local event.
But that in no way means that the competition isn't great, and it really shows what the machines are capable of.
