Hi Jelle. Very interesting as it shows clearly the effect of speed on the range. I also wonder how realistic it is in real life. As you mention, your driving was very constant thanks to quiet traffic conditions, airco turned off, etc...Jelle v/d Meer said:I did 2 real world efficiency highway test at 104km/h and 94km/h on the speedometer - both were done on quiet highways, ACC set, exact same route (triangle highway route so constant speed see the only 0.1kW regeneration), only 2 sharper turns (speed approx 70km/h for less than 1km), outside temperature 17-18 degrees, Eco mode, air off and just me in the car.
I have for majority a Jaggg driving style (not caring about range as not needed) on longer trips I prefer speed over range (faster to drive quickly and charge more often/longer than drive slower to max range) - majority of trips are less than 10km. Made 2 long holiday trips (1900km and 3000km roundtrip) enjoying the Autobahn (160-180km/h on ACC) and Austrian country roads (traffic jams on highway).ricardon said:Hi Jelle.

Now, from your activity on the forum I guess you have been keeping tabs on your consumption quite diligently, so I was wondering if you could present a figure after 1 year ownership and talk a little bit about your usual driving style.
Hi Jelle. We share the same driving styles .Jelle v/d Meer said:I have for majority a Jaggg driving style (not caring about range as not needed) on longer trips I prefer speed over range (faster to drive quickly and charge more often/longer than drive slower to max range) - majority of trips are less than 10km.

So far did 17,200km in about 8 months with an overall average of 292wh/km where in winter months it was around 310wh/km, last month 275wh/km and so far this month 263wh/km.
Your constant speed consumption is exactly 5% better than mine when it was 10 degrees C, Jelle. We have the same spec. and wheels so I'm guessing it was slightly warmer for your test?Jelle v/d Meer said:
- 104km test - avg speed 101km/h (=63mph) - 216wh/km (=348wh/mile) so with 82kW usable 380km (=236 mile) range

- 94km test - avg speed 91km/h (=57mph) - 195wh/km (=314wh/mile) so with 82kW usable 421km (=261 mile) range
Outside of winter, that sounds about right for 22" wheels. You should get more on smaller wheels. In winter I'd say you'll get a bit less than that even on 18" wheels. Maybe around 200, less again in bigger wheels. Obviously this will vary with terrain, winds, weather and driving style, but as a ball park, I'm getting around 220-230 in summer on 22" wheels.ProjectZ said:I'm still debating wether to get iPace over a Model 3 performance, it's a close race but my heart says iPace. I had an iPace for the weekend in picked the car up with 97% battery and drove 89mi + 27mi + 79mi being a of total 195mi with reasonably cold weather and mostly very wet roads. Coming back from Middlesbrough to Kendal it was predicting I'd be 10 miles short of home, so I stopped at scotch corner services for a 50kw charger. I was able to add 27.7kwh in 48min. I recon a 100% battery would have just got me home. Still it afforded me the scenic route after the charge and I made the the most of the awesome acceleration and handling. Still I recon 210-220 miles is a reasonable expectation, sound right?
If Range is the deciding point then I would suggest:ProjectZ said:I'm still debating wether to get iPace over a Model 3 performance
Yep.ProjectZ said:....Still I recon 210-220 miles is a reasonable expectation, sound right?
Thanks for the info, yeah you're absolutely right, my average long ish journey round trip is around 170mi. Wether it's our friends near Burnley or a trip to the Trafford centre. I probably do that kind of trip every other weekend. So I should be good for 170mi round trip without needing a charge.TeslaDriver said:Biggest problem with charging iPace (or a Tesla at 3rd party charger) is that it is almost universally dreadful Tesla Supercharger experience is literally plug-in walk-away. the other players need to achieve that too (and new players like Ionity looks like they are going to be doing just that). Bit of chicken-and-egg in terms of timing therefore, so your call on how much lifestyle-change you are prepared to accept in the short term. But if you are only out-of-range a coupe of days a month, and those routes have good charging infrastructure, then it may not matter.ProjectZ said:I'm still debating wether to get iPace over a Model 3 performance
Actually, this method should be quite good. If you use X out of Y kWh to go 39 miles, then the range if you use the full Y kWh is 39*(Y/X). The only error here would be if the charger loss is not constant for a particular car. I think the assumption of constant loss is OK as long as you are using a slow charger. With a rapid charger you will start heating the battery and a lot of stuff might happen, which will influence how much charge you can put on the battery.DougTheMac said:Getting back to the original post, the What Car text methodology seems a bit strange. They discharged to zero, then measured the energy taken to fully recharge. Then they drove just 39 miles, and then measured the energy to recharge to 100%.Paul J. said:In case you haven't previously seen this: https://www.whatcar.com/news/what-car-real-range-which-electric-car-can-go-farthest-in-the-real-world/n18159
IMHO, a valid method of measuring efficiency (miles per KW-Hr IN), but a rather dubious method of measuring "real world range". Rather sensitive to charging efficiency, battery management system losses, charge rate, etc. Why didn't they just keep driving until the battery was flat?
I think we'd all agree that the result for the I-Pace was a bit flattering - 253 miles at 10-15degC, climate on at 21degC, headlights on, normal mode? Even on 18" tyres, that sounds optimistic. The average speed isn't given, but it does say a mix of urban, rural & motorway.
I'm still hoping for more than 200 miles one day soon!
I have no problem with the maths but rather that any "set off energy penalty" such as warming the battery and HVAC for cabin (or, indeed, "set off bonus" if car had just been rapid charged and battery was more optimum than normal driving) is averaged out over so few miles ... hence I prefer a figure based on a decent journey-leg length - e.g. at least 75% of battery capability.ghost said:If you use X out of Y kWh to go 39 miles, then the range if you use the full Y kWh is 39*(Y/X).
What was it like? your impressions?Chewy said:Just had a test ride in the new Kia eNero.
Range wise, this car will easily do 300 miles

Far better than the 2018 Leaf, which is a lot more expensive.ChrisMc said:What was it like? your impressions?Chewy said:Just had a test ride in the new Kia eNero.

Interestingly (or not), I looked at what the car had averaged over it's short life of around 2300 miles. It has averaged 4.4miles/kWh. That makes it pretty much spot on for 282 miles range as advertised.ChrisMc said:They do say 282 mile range on their site but I guess for Chewy its well over 300.
