Quick response to the Motor Trend article (I will watch the video next)
Overall I'm always blown away by the unfettered enthusiasm .. the only issue ever is the charging infrastructure, which will improve so dramatically over the next three years that it will not be an issue.
If the car is *that* good I don't mind researching the route and possibly waiting 1.5hrs for a charge.
I now have 10 youtube videos bookmarked, all relentlessly enthusiastic. 8 written reviews, same. This car/suv/crossover/? is a game changer and I'm so totally stoked to have ordered one!
I have both a 'Want one' reservation in for an I-Pace and a $1000 'deposit' on the Tesla M3 so I'm following this with interest.
Some thoughts....Tesla does a lot of stuff on the fly and uses early adopters as beta testers (much to the disgust of the auto crowd) We keep hearing that 'real motor' companies will test all Beta stuff before bringing a car to production - hence the endless testing and mules/camouflaged cars seen haunting the roads prior to release. Ditto the I-Pace.....
But it seems that Jaguar is so determined to beat Audi and Mercedes to market with an EV SUV that they have rushed the I-Pace a bit prematurely into 'production' - not withstanding the delays due to the headlights (Huh?!)
I'm fairly sure that the range issues with the I-Pace are not terminal or indefinite and are most probably software related. Even the Jaguar engineers seem to be calling aspects of the I-Pace "Beta"...!!!
I don't have any illusions on range; it will likely be less than 240 US miles for most people. Software updates will tweak it around the edges; but in the end your range will depend on how fast you drive on the freeway and whether you use the one-pedal mode around town. It's basic physics ...
They did say at the onset that the purpose to the test is to find out how close to the new WLTP standard ranges are the actual driving ranges. Some cars are over and some cars, like the I-Pace, are way off. The caveat being that the Jaguar is a pre-production model and is still tweaking the software.
My P90D is a bit shy of 90kWh usable. Its fine for 220 miles at 75-80 MPH.
A Jag has newer motors, and a genuine (as I understand it) usable 90kWh, albeit slightly worse CD than Tesla, so I think it is likely once they've finished fettling the Jag that it will be 200+ miles
Dunno about everyone else, but range only matters to me on a trip, and that means I'm on the highway on cruise control, so everything is well placed for efficiency (other than the fact that I'm doing 80 MPH rather than 20 MPH obviously )
Here in the UK I can guarantee a stretch of roadworks or traffic at 50 MPH on any long highway journey and that takes care of my range anxiety I might otherwise have had
Yes, but real world range varies. A lot. Some days, I drive 100 freeway miles, and other days I drive only locally. Both days are 'real world', and range differs substantially.
All I want is a single benchmark standard that is representative of some reasonable mix of highway and city driving in consistent road conditions, weather, etc. Then I can compare different cars, and adjust as needed for my own driving habits, approximately. Maybe the WLTP standard is sufficient. The EPA standard is not great - the testing is done by each manufacturer, not by an independent tester, and even worse, the manufacturers are allowed or even encouraged to understate results. Tesla, for example, is apparently understating EPA range for its single-motor Model 3, so that it can show the same range for all current versions of the car.
My month-average is quite a lot higher than my trip-average. On days where I am driving within range I don't care much, and shorter journeys etc. are also not representative - especially in Winter when there is a signifcant power-penalty starting a journey (even if the car & battery has been pre-conditioned)
Of course not everyone's 200+ mile out-of-range journey is highway on cruise control ... mine invariably are. In our Winters I am 20% higher in February than best (not too hot) summer day.
My advice to people thinking of buying a Tesla is to use A Better Route Planner, pick the model, set the temperature (once for summer, again for winter) and perhaps fiddle with the other settings, and then pick some actual range-challenging journeys and see whether they would get there, and if not how long they would have to "refuel" (supercharge in Tesla's case, but once CCS is here it will be "similar" for Jag too)
ABRP seems to be pretty accurate (data is collected from volunteer owners), and now also includes Bolt and Ampera, and no doubt others too in future. Once it has Jag data I think that would help , but in the meantime even choosing a Model-X 90 (no longer made, but similar battery size) and compensate by setting whatever Wh/mile seems like a good guess, should give a reasonable stab
(the video was 441 Wh/mile, I think production will be better than that pre-production; 290 is granny driving, 330 would be very good. I am 330 in Summer with some road work / traffic 50 MPH bits, 350 at a steady 75MPH cruise and 370 at 80mph, and mid winter 380 - 430 on highway cruises)
My range has improved by 33% from a low point in December (162 miles/260km) to May (243 miles/391km) but I was surprised by the results of a recent test that I conducted. Last November I wanted to see how much the use of climate control had on cold weather driving so I drove a 37 mile (60km)...
New member considering an i-Pace here.
My expertise is in the aerodynamics of racing cars.
One thing I have noticed on the internet is some discussion and disappointment on range of the i-Pace.
Whilst my expertise is not road cars the wheels and tyres have an important influence on drag. I...
I have made a quick spreadsheet that I think is useful for trip planning. (See Picture). I put in my real world range per battery % (which, my highway range is about 2 miles per % of battery, so I use 1.9 as a conservative number in the picture). Then, I enter legs of my trip and distances...
So can anyone explain this math to me
I drove 11.2 miles today.
Jag App said it used 2.34 mile/kWh
11.2 / 2.34 = 4.78 kWh used to drive 11.2 miles
JAG app said I regenerated 4.6 kWh. I drove on free way and showed down from 70 to 40 mph many times in order to regenerate that much power...
