Maybe they performed precondition. Or maybe they did not have enough time and/or charging stations.

Anyway EQC, ETRON, I-Pace and Model 3 all ended up with similar percentages of WLTP range. If we instead compare percentage of EPA range I-Pace did very good compared to Model 3. The I-Pace was definitely not on 18 inch wheels so it's fair to say that I-Pace did around 100% of its EPA range.

Range and charging calculator IPace. (google to find it)

This is a Jaguar calculator that predicts the range under different conditions, temperature, wheel size, and speed, the range test achieved EXACTLY the predicted range in those conditions, yes, it is a lot less than the 292 miles claimed, achieved in urban driving. The same calculator also predicts 200 miles range motorway driving.

Preconditioning also seems to be a big factor, the test cars were charged the day before so the batteries were cold, if they had been at optimum temperature, 20C, the predicted range would have been 260 miles. Those batteries weigh 400kg it must take a significant amount of power to raise the temperature, so pre conditioning when plugged in charging seems to make a big difference

For some reasons the cars did not start at 100%. They say that the cars was fully charged the night before or so, but lost some during the night.
Very strange. There is a picuture of the I-Pace holding a 96% charge I believe.
Yeah this bothered me. My car has never sat overnight and lost 4% and more bizarre, that all their test cars, from all manufactures just happen to do the same thing...odd. Something not quite truthful.

That all said, based on their video, the conclusion:

The I-Pace did circa 225 miles from 96% battery, in winter months, on 20" or 22" inch wheels, likely without H264 with the bulk of the drive on the motorway and they used cruse control set the speed limit (all bits of information taken from their video). That's a 250 mile capable car, if not a bit more in summer months. You have to give JLR credit where it's due.

The German brands are not even coming close presently.

Fact is that Ipace reached the lowest % against the supposed range.
Last with regards claimed range - the 292 miles of the I-pace is city range (avg speed 23mph) so bit odd to compare claimed range vs real world range if you do the test for 90% on highway.

Jaguar still claims/advertises the 292 miles of range without indicating it is max range (city range).
Actually Jelle the WLTP test is 30 minutes long divided into 4 different sub-parts, each one with a different maximum speed:

Low, up to 56.5 km/h
Medium, up to 76.6 km/h
High, up to 97.4 km/h
Extra-high, up to 131.3 km/h.

These driving phases simulate urban, suburban, rural and highway scenarios respectively, with 52% of the test time in urban and 48% of it in non urban. The average speed overall is 53km/h.

As with most vehicle test procedures though it is still overly optimistic vs. what owners achieve in the real world - by 20% in the summer and 30% in the winter in my experience. Which seems to match Carwow's.

People should note that there's a difference between "claiming" and "reporting" the result of a standard test. ;)

I know that is the WLTP test however the output in consumption is a city consumption, highway consumption and combined consumption.

For BEV the max range is based only on city consumption - almost all manufacturors advertise with the max range saying “up to xxxkm range” although Jaguar left of the “up to”.

Very likely Hyundai/Kia choose to use the combined consumption for range prediction and therefore in real world get much closer to claimed range.

Jaguar on their website now reports for an I-pace on 18”, 20 degrees and AC off:
City 470km (292mi)
Combined 406km (252mi)
Highway 317km (197mi)

Which is around what I do with my i-pace.

I just went onto the Jag range calculator. I selected Motorway driving, Aircon/heating on, 20" wheel size, and 10 degrees temp.

Calculator suggests that the range should be 172 miles. If going for 'combined driving profile' it calculates 212 miles. So arguably, it overperformed in the test.

I like the carwow reviews generally, but when it comes to providing factual information, they are typically flawed. I think I recall Matt also stating a 0-60 time of 4.8 seconds when it should be 4.5 seconds.

When tested the I-Pace usally do the 0-100kmh in 4,5-4,7. Several US tests have 4,2-4,3 on 0-60mph. So Jaguars claims are pretty conservative.
