I had the same issue. Trying to compare Tesla to another actual EV, on that forum results in flames from the fanboys.
I had a Model S for 50,000 miles, and my wife has a 3. I'm also following the ipace closely...
So far, I've determined, the iPace is
Unknown EPA range rating
No super charger network
Range Rover looking interior
About $13-18k cheaper than a Model S.
Dealer is MUCH closer to my house
Top speed is less than any Tesla Model.
Jag doesn't have mobile repair services.
Tech in the dash isn't up to Tesla, but it's MUCH closer than anyone else.
Doesn't come with a UMC equivalent. - but you can get one that plugs into a NEMA 14-50 if you have that outlet already.
No autopilot or FSD options.
And, I think it's law to pronounce it "Shhhhhaaaggguuuwwwaarrhhh". It annoys the wife, but it's hilarious.
The press has mentioned it's one of the best handling SUV/CUVs. The handling is user adjustable on optioned cars. Steering weight, dampening, tip-in, can be programmed, or you can let the car decide what settings matches the road.
EPA range not determined. Hypermiling will reach 291mi or more.
It has a "7kW" on-board, probably 7.2kW (32a x 240 1ph US).
Euro spec EVSE appears to charge at 100-265v, at L2 speed.
US spec EVSE has zero data so far.
It uses CCS DCFC at a speed that is not locked in yet. Is it 80kW? Is it 100kW? Will it be 120kW? All these numbers have been mentioned by JLR engineers. The charging speed can be changed via OTA updating of the battery controller.
Similarly equipped in the US, it's about $8k cheaper than the MS75D, but the i-Pace will have more features at that price.
Top speed is 200kmh or 124mph. The ACC is mentioned to work at 112mph.
Mobile repair is not offered. It's a 5yr/60k bumper to bumper, JLR InControl Remote and Protect, OTA updates, WiFi hotspot, Carplay/AA.
Read the owner's manual from my post above for all the features of the dash and other controls. Pretty extensive including traction mapping for ice and sand.
It has ACC and "self-steering", but nobody has evaluated it. It appears to work to 112mph.
