I still see a number of problems ahead for them; the main one being their sales numbers are nowhere big enough to survive at the current rate.
1) Jaguar have an unappealing image for those aged under 60... by definition that is a growing market... over 60 you tend to die... This is why their BMW 3 and 5 series rivals never do well; the -pace range seem to be doing OK at appealing to those under 50 a bit more.
2) Land Rover have a mis-mash of offerings that compete and canabilise one another (and then canabalise the Jaguar rival offering as well as people cross-shop)
To make the LR work it needs the range to look something like:
-LR Discovery Sport: Softroader+, 2 litre ish engine, IFS & IRS, 2wd option, 4wd with HDC and a crawler 1st gear (like the old VW Syncro), about the same size as a Jetta Wagon in footprint, 5 doors, 5 seats
-LR Discovery: The Good car for a farmer to take to town; some commonality with the Defender in terms of platform/engine, IFS, live rear axle, 3ish litre diesel and petrols, low range transfer case, 7 seats. Rival a Prado/Fortuner/Ford Everest/Isuzu Mu-X/Holden Colorado7 (or whatever they're calling it this week)
-LR Defender: SWB, LWB, XLWB (90, 110, 130) single cab, double cab and wagons. Much more basic interior, detuned engine, IFS & live rear axle, engines as Discovery, 7-9 seats. Rival a 70 series Land Cruiser but with a bit of flair.
-Range Rover Sport: The farm owner's wife's car... 2.5-3.0 petrol or diesel, can be a monocoque, bit of a test bed for new tech, more gadgets and gizmos, 5 seater,
-Range Rover: Farm Owner's car; 3.0 petrol/diesel or 2.0 + hybrid, IFS & IRS, air suspension 5-7 seats, nice trim $$$ price tag.
I have a recollection that the original Discovery was the same price as the Defender when it was launched... how did they manage that? They raided the parts bin... they've now been too used to making things for only one model, not sharing stuff.
