The core "heritage" of the brand is represented by the Range Rover, the Disco and the Defender. Hopefully those 3 vehicles will stay true to their heritage and remain supremely capable offroaders out of the factory (I trust that will be the game plan of Land Rover for the long term.)
The remaining models in the lineup were introduced to fill niches that did not exist 10 or 20 years ago, so I guess Land Rover should be allowed a little latitude when it comes to fitting them with serious off-road toys because they need to appeal to a "non-heritage" crowd that would otherwise flock to other brands.
Even the Sport - as capable as it's always been off road - was really a bit of a ripoff considering it was basically an LR3 in drags, more expensive, less spacious and with a high power engine as an option for keeping up with BMW, Mercedes, etc. I knew quite well that I was being ripped off when I bought mine back in 2005, but at the time I could care less about its off-roading capabilities and fancy suspensions - the off-road bug bit me a year or so later. I just loved the looks, the luxury, the size, the sports car feeling behind the wheel and, well, the Range Rover badge on the hood. I remember the salesman dressed like Indiana Jones telling me my car (I bought the fully loaded showroom model, with every possible option including some garish chromed factory rims...) was even equipped with "an electronic rear differential", and I had no idea what the hell he was talking about. I just kept nodding and telling him "Whatever man, when do I get to take her home?"
At least the Sport can now claim to be more of a Range Rover than the LR3/4 impostor it was before, it's built on the same platform but still looks like a sportier version of it, even the interior is super posh and hard to distinguish from the flagship now. It just has less factory toys than the big Range, but at least they are still available for those who would really like the luxury and capabilities of the full size Range Rover without the bulk and $100K+ price (and by the time you are done accessioning it, the new RRS can easily top $100K itself.)
I think Land Rover has a winner in its hands withe the new Sport. It may not represent the true heritage of Land Rover, but I don't think it's meant to. It's meant to sell a lot of units, like the Evoque.
