What’s the difference between the ‘luxury’ Range Rovers and ‘leisure’ Discovery models then?

According to McGovern, the Discovery family will increase its ‘premium execution’, which will move the new models closer to the Range Rovers, but also serve to broaden their appeal. McGovern says the utilitarian Discovery 3 proved quite polarizing, but the mid-life facelift that turned it into Discovery 4 (with a posher Range Sport interior and no more black plastic body cladding) was much more popular with customers.

To differentiate Discos from RR, the former will be much more versatile, with seven seats, lots of stowage space for families, and practical touches, whereas the full-size Rangie will only ever seat five and the Range Sport, at best, remains a 5+2.

What about this new family of Defenders?

If the RR and Disco sit closely together, McGovern says the new line-up of Defenders will stretch out the Land Rover brand. ‘Discovery is getting closer to Range Rover,’ he says. ‘But the Defenders, when you see those coming, they’ll really bring clarity to the three-family scenario. They’re out there, a working tool, probably closest to the original Land Rover heartland, but still relevant.’

And whereas McGovern worries a utilitarian look limits the appeal of the Range Rovers and Discos, it’s less of an issue for Land Rover’s third family (previewed by the DC100 concepts, above). ‘For the Defender it’s something else. There is that utilitarian look, but it’s inextricably linked to the original so you get over it. The Defender is about durability – you kick the hell out of them and they get up for more.’
