I hate to be the contrarian, but LR is a business. They need to sell cars.
Ever notice how much the new Explorer looks like a Range Rover? Or how much some Hyundai cars look like MBZ?
I rented an Impala last week and parked it next to my daughter's new Accord. Both were silver. All week I couldn't figure out which car to walk towards.
A manufacturer has to make some basic choices- they can either build something that looks like something else that's more expensive and sell them to those that want the expensive one but can't really tell the difference, or build something different- and try to leverage the history behind the product. Tata probably spent more than the lifetime earnings of everyone that will ever visit this forum on the design, from models to focus group testing, so I'm guessing they went with the direction their target buyers pointed them towards. I think the new design looks dramatically different than what you see out there. Cars these days all look alike and I rarely notice any of them, but I always notice the new one's.
And let's not discount the fact that for the first time in a very long time Land Rover is a stable business selling a quality product that people want to buy. Something that Leyland, the UK government, British Aerospace, BMW and Ford all failed at.
Truth be told, I always hated the look of the Discovery. When it came out, I thought it looked like a girl's car. It lacked the style of the Range Rover and the cool utilitarianism of the Defender. It took almost 20 years for its funkiness to grow on me.
