I'd say it's safe to assume it'll be IFS/IRS and only visually different than the Discovery 5. We haven't seen any "spy shots" which means it's probably been tested as a Discovery 5 the entire time. It's about a year out from being released right?
I hope it's great. I'm expecting complete disappointment. The author from that article doesn't get the heritage, or has somehow forgotten it. "McGovern's previous work on Range Rover and Discovery, I believe, point the way to the next Defender. When the Range Rover was replaced in 2013, the basic shape stayed the same. The sloping roof remained and the shape of the side windows was evolutionary, not revolutionary. The biggest appearance changes came in the vehicle's jewelry -- the headlights, taillights, grille and exterior badging. All were new and fresh and yet were reminiscent in some way of the brand's styling cues. The interior became softer and more sophisticated."
The headlights, taillights, grille, and badging were all forced upon the brand by McGovern starting with the Evoque. It then bled into every vehicle. The grille is maybe reminiscent, the lights are the farthest thing from that. Now they look like every other car on the road. I'll add that a lot more garbage skirting was added to the shape of all the vehicles. They are truck/minivans. Trinivans.
