WLTP -20%What does 3 mean that; the 88 kwh will produce 270 mile (430 km) epa range in an AWD like estimated? I was leaning for 450 km and a small increase; guess now that will be surprising.
I thought that
NEDC minus 17% for real world
WLTP minus 8% for real world
EPA minus 2% for real world
was a rule of thumb. That places EPA at about a 6% difference but does not line up with the estimated EPA unless there are different batteries 600 (375 mi) x 0.94 = 564 km 352 miles does not line up with an EPA of 300 miles? Different packs for Europe?
EDIT: 600 x 0.94 x 88/100 kwh = 500 km 310 mi?
I am getting that; like Tesla inflating their numbers to report that -20%. So you think that WLTP can be stated as much as 40% over the EPA numbers.WLTP -20%
EPA + or - 20%
That's the joke for the electricvehicles subreddit. EPA isn't that consistent from car to car.
There should be a 10-80% average kW and time rating.
Part of it is the EPA allows additional tests to alter the adjustment factor, which on a few companies (like Tesla) have done. From: https://www.caranddriver.com/featur...-factor-tesla-uses-for-big-epa-range-numbers/ :WLTP -20%

You mean at the discretion the administrator; I read that standard. The standard kind of say the administrator can be helpful if the auto maker provides the right incentive. The scalars should be 0.7 mandatory and I would like 50/50 highway/urban. My cals say the same; the Tesla Y used 0.7578 instead of 0.7 which is only a 24.5% instead of 30% reduction. Of course that discretion is realized when they hit the streets and you start to talk real world. They needed to beat the Kona's efficiency and found the right incentive is my guess.Part of it is the EPA allows additional tests to alter the adjustment factor, which on a few companies (like Tesla) have done. From: https://www.caranddriver.com/featur...-factor-tesla-uses-for-big-epa-range-numbers/ :
The default adjustment factor reduces the window-sticker range by 30 percent. So a car that achieves 300 miles of range during the city-cycle dynamometer test ends up with a 210-mile city rating. However, the EPA allows automakers the option to run three additional drive cycles and use those results to earn a more favorable adjustment factor. Currently, only Tesla and Audi employ this strategy for their EVs, and Tesla scores the most advantageous results, with adjustments that range from 29.5 percent on the Model 3 Standard Range Plus to 24.4 percent on the Model Y Performance. If Tesla had used the standard adjustment factor of 30 percent, the Model Y Performance's window-sticker range would drop to 292 miles. But because Tesla takes advantage of the EPA's alternate methodology, the company can instead claim a 315-mile range.
Ignore? So 68 mile range and I am good to go.Frankly, buyers ought to just ignore EPA and WLTP and wait for YouTube reviewers. They're usually far more accurate.
What the EPA range estimate will be most useful for is comparing vehicle to vehicle under similar driving conditions, especially if those conditions are close to those used for EPA testing. So if a Mach-e goes farther in an EPA test than a competitor, it is a fair assumption to say it will go farther in MOST other conditions (70MPH cruise, etc). The opposite is also true.Frankly, buyers ought to just ignore EPA and WLTP and wait for YouTube reviewers. They're usually far more accurate.
Well ok, let's say take it with a grain of salt. ?Ignore? So 68 mile range and I am good to go.
What I am saying is it should be transparently fixed so all can calculate it. It then becomes a fixed variable that can be used to forecast different scenarios. Allow the administrators discretion is where the variable is no longer fixed. All should have the same rules and one test.
Doesn't matter as long as it is a fixed variable you can with reasonable accuracy predict what that 70 mph result will be. When "At the administrators discretion" to quote the standard all bets are off and it is now all political.Well ok, let's say take it with a grain of salt. ?
Agree that it needs to be transparent and consistent. But even more importantly -- a real world scenario. Range in BEVs mostly matters for long road trips. That means high speed, not 48 MPH (which is a joke as a "highway" speed).
I still wish they'd just take them to a NASCAR track, do 10 laps at 70 MPH, and report the miles/kWh (the counterpart to MPG). Now that would be useful info.
Not so much on the open end though. There can be a lot more variability extrapolating up from 48 to 70 or 80 than extrapolating between 70 highway and 30 city. Drag can get exponentially worse on the high end.Doesn't matter as long as it is a fixed variable you can with reasonable accuracy predict what that 70 mph result will be.

Agree it could change but should change for all. Does not change my point about not making it political. Does not change my point that with a fix variable extrapolation is possible.Not so much on the open end though.

And more to the point, 48 MPH is just highly atypical as a highway speed. Pick a REAL highway speed as "highway" so you're at least close for most people.
Change for all BEVs, anyway. From a consumer standpoint, I'm not really concerned about a BEV vs ICE comparison. That's so apples-to-oranges anyway. Range is HUGE in a BEV (because of slooow and sparse refueling) but mostly irrelevant with ICE. And it's frankly silly to try and treat gas and electricity the same. MPGe is an almost comical construct.Agree it could change but should change for all. Does not change my point about not making it political.

The US06 cycle has a top speed of 80.3mph. Aero measurements are done to this speed, anything higher would be extrapolated. So for 70mph, any manufacturer has a MEASURED aero drag value.Agree it could change but should change for all. Does not change my point about not making it political.

I wish the EPA would just give us a range number using that, instead of diluting it with so much low speed data and coming up with a 48 MPH average which is woefully slow as a "highway" number.The US06 cycle has a top speed of 80.3mph.
