I have to wonder though if some R & D may in fact produce an eventual OTA software update which improves motor/battery efficiency a bit? I can see this happening at some point in 2019...and Jaguar can even make a big deal of it with a full Press Release and/or Press Conference announcement of some sort...would make for a very good marketing campaign for current and future Jaguar EV's. They could do a free OTA update for early adopters of the Jaguar I-Pace like us...first 2019 I-Pace owners and/or charge future customers like $500-$1,000 or so for a software update which increases performance and range (e.g. the Tesla "Performance" software package)...it's certainly possible. I wouldn't mind a simple, quick OTA software update to increase 0-60mph performance to 3.9 sec. and extend range to ~ 275 mi. That works.

It seems like the 90kw battery has the capacity for this anyhow, but from what I've read, it's the 2 magnetic synchronized motors which make it less efficient. Apparently, the Teslas have 1 motor (of 2 for dual motor) which turns off when cruising on the highway or something like that...makes it much more efficient.
