2019 Jaguar I-Pace gets official 234-mile range rating

It remains a puzzle with current speculation about the tires and suspension. You might have noticed the I-Pace reveal included a lot of rough terrain climbing which is typically done with 'knobby tires.' High rolling resistance tires, rough terrain transfer cases, and suspensions tuned for rock climbing (excessive toe and camber) may be the root cause.

Ah, that's interesting. These may attract a slightly different kind of buyers, one who doesn't focus just on EPA range and is also interested in off road activities.
 
The I-Pace appear to begin with a bang and appears to be ending up in a whimper. They started off with a range of 270 miles plus, the road tests by users seem to indicate more like 200 miles. Jaguar may have done some optimization and brought it to 234. Even on other performance parameters it does not seem to be better than the Tesla S. Unfortunately for Jaguar, they have no room for error, as it will be compared against the S. The only saving grace is that you will get the $7500 tax incentive after Jan 1st, Tesla will come down to $3750. I had high hopes for the I-Pace, the news coming out does not indicate it is a Tesla killer. Their only hope is to attract the people who focus on off road (as mentioned by @TeslaInvestors ) and the never Tesla folks.
 
Well, we got to be careful here. EPA range doesn't mean its like some gold standard measured by a neutral party. Most of it is measured by the manufacturer itself. As we know, Tesla's range claims are on the optimistic side while Bolt (and also SparkEV before that) have been quite conservative. See consumer reports' range test with Bolt for proof.

The most important fact is that the EPA does only a small portion of the certification testing. Instead, the manufacturers do the majority of the testing, with the EPA reviewing results documents submitted by manufacturers. The same is done with other regulatory agencies around the world. Since the manufacturers do the testing, there's some room for finagling. That's led to occasional instances of manufacturers having to restate their range estimates or fuel economy estimates (in gasoline vehicles). The big example of this sort of finagling is the Dieselgate problem causing the Volkswagen Group so much troubles.

Ultimately, if a manufacturer claims overoptimistic ranges that leads to a consumer lawsuit, the manufacturer loses face and eats crow. So a manufacturer who wants to stay in business long term and build customer loyalty may want to play it safe.
As an example, see this long range Model 3 owner already realizing that Tesla's range claim was a fraud. Tesla might have put on the thinnest of tires with low rolling resistance and driven on he days with best weather in California on an easy route. This jibes well with other similar things they have done regarding everythign from claims of cost savings to FSD to AP 2.0 to horse power numbers of P85D.

EPA tests are done in a lab under controlled conditions, not on the road. Application for the Model 3 long range with full details:
https://iaspub.epa.gov/otaqpub/display_file.jsp?docid=40001&flag=1

In five cycle testing, the Model 3 achieved 371 miles of range. The standard derating of .7 takes that to 334 which Tesla then voluntarily lowered to 310.

Interesting to note that a full charge took 89.4 kWh, which indicates an ~80 kWh battery is likely fitted in the LR (as opposed to the widely reported 75)

Does this suggest that I-Pace should actually get around 170 miles in real life, if EPA is 234 miles? That will really put I-pace out of business.

That tweet is ridiculous, though reading through his tweets, it's hard to tell if he' serious or sarcastic. He's driving 80-85 miles an hour with stickier tires than stock and then saying that his range has dropped.

Unfortunately one person who is off the wall becomes a poster child for nay sayers.

I wouldn't take one vehicle's results to make an inference on another. I imagine the I-Pace will get over 200 miles for most, and close to its EPA numbers when driven slightly conservatively.

Thanks for the info. Still, some makers seem to put out more conservative numbers. How do you explain that?
Are they deliberately putting lower numbers just to avoid negative publicity when real life range turns out lower?

Like here is Chevy Bolt vs, Model S 75. I assume, CR knows what it is doing. Article claims, EPA range is under almost ideal conditions that are hard to replicate in real life? I am not sure if that's true or not.

Chevy Bolt outlasts Tesla's Model S in Consumer Reports range test
It also somehow beat the EPA's estimate -- not an easy feat.

Here is how CR tests electric car range.

CR reports two MPG numbers, their test track and highway numbers. Their highway numbers are spot-on with the EPA metrics but their track numbers are consistently worse for high MPG cars like the Prius.
