Is the efficiency for the Zoe 50 correct? With similar battery to the e-208 but more range should be more efficient. Or does it means the on-board charger in the Zoe has huge energy loses?

No way a newly designed Peugeot 208 / Opel Corsa are less efficient than the e-Golf. In other words: if the e-Corsa indeed consumes an average of 17 kWh/100 km, then some engineers at Peugeot / Opel need to be severely punished and then fired to spend the rest of their lives in repentance. We’re talking ~25% less efficient than an Ioniq. That is outrageous for a car in a lower segment.

ZOE: 52 kWh / 395 km = 13,1 kWh/100 -> 24% energy loss
e-208: 46,3 kWh / 340 km = 13,6 kWh/100 -> 20% energy loss

Then ZOE also should win. Looks like the e-208 motor, inverter and charger are a little more efficient than ZOE’s (not huge difference though).

Forgot aerodynamics and weight as a factor… Anyways surprised by the high efficiency of Hyundai’s SUVs. It is not what you expect at this category.

These numbers confirm that aerodynamics/cx is very important (the Hyundai Ioniq efficiency is amazing) and yet automakers are not really interested in making saloons/estates but want to make SUVs. Partly because SUVs are more profitable, but while profitability is greater for ICEs (bad fuel efficiency is the customers’ problem) with EVs it is the manufaturers’ problem (need to put big batteries in to achieve decent range, and that costs money). Not only that, but the efficiency difference between good and bad CX cars would be even greater where it matters (at 70mph). After all no one really cares that their car has a range of say 300 miles at 30mph, we are concerned about motorway range!

If possible, in a next revision of the table, add a UoM selector

– imperial (miles)
– metric (kilometres)

and an efficiency presentation selector

– kWh / 100 UoM
– Wh / UoM

Thanks.

The Nissan Leaf figures must be wrong. 270 km at 206 Wh/km gives just over 55 kWh. The battery has a capacicity of 40 kWh, with no more than 38 kWh available. That would mean 1/3 of energy is lost between wall socket and battery. Can’t be true.

It would be interesting to add the Porsche Taycan to the list. The Porsche website states an efficiency of 26,0 – 26,9kWh/100km (WLTP), depending on the model. Given the very aerodynamic shape of the car I find it pretty amazing that it manages to get an efficiency rating even worse than the e-tron. Obviously Porsche engineers were optimizing the car for performance and not efficiency, but still.

I dont see the need to present data in imperial units, since almost all countries use metric. If one needs to convert from km to miles or vice-versa it’s as simple as multiply/divide by 1.6 roughly. Even NASA learned their lesson after losing a Mars probe at the north pole because they fucked up using imperial units.

If the power consumption is measured at the plug, you should mention at which current it is measured. The efficiency of the Zoe seems to be underestimated in your table. If you measure at 10 amps/2.3 kW, you will have worst results than at 22 kW….

where is the Tesla model S or X on this?

My best friend was driving a white sGolf for a while, & now gets MUCH less efficiency in her white Tesla 3 “std+”. 33% less, accorrding to the dashboard readouts. The specs above show her T3 as more efficient than an eGolf.

Yes, I know T3 charger may be more efficient, but eGolf’s must not be THAT bad, since it’s much cooler to the touch than my Fiat 500e’s

According to dashboard readouts, her T3 “Std Plus” averages around 28kWh/100mi & the eGolf only took about 21, similar to my Fiat 500e.

The Lightyear one 451 mi range is too simplified, must have so much “fine print”. I mean, regarding the “solar yeild” part of it. winter vs summer, cloudy days, night time driving, bird Sh*t on car… etc you cant guarantee a range.
Dont get me wrong, lightyear one and Sion (not on list?) have potential to be great cars, but the “range” can not be summerised into one number! They should be honest and write the range assuming NO SOLAR, and then an potential extra SOLAR BOOST.

eg. if you drive slow enough (through the night) maybe it can have infinate range!!

… all the informatoin you need to add the sonomotors, Sion (Solar) is on this PDF from their website. Although it is low’ish range, it is more that the VW e-golf on your list.
Electricity consumption…………………………… ≈ 14 kWh/100 km
Range(WLTP)…………………………………………………………………………255 km

Sion also isn’t an unaffordable luxury like Lightyear, & seems closer to actual production.

Sion’s 14kWh/100km WLTP, is nearly as efficient as ioniq, but in reality the solar cells would actually beat it unless you keep it shaded all day.

Maybe if you drive a Sion or Lightyear slow enough during daylight, & stop to sleep at night, you could go an infinite distance per plugin charge. Under those conditions you could probably drive faster if you removed the battery!

Me (& probably Ateeq) were really only half-serious about infinite range, although I did check that here in the southern US the sun is stronger in the middle of winter than it is in the middle of summer where Sion said they measured it (in Germany), so my own personal driving would actually all be easily covered without ever plugging in. I could probably even power my small A/C-less apartment with the left-overs!

Something is wrong with this table, since it shows the Kia Niro to be more efficient than the Hyundai Kona, when the opposite is the true!

Does anyone know the impact of equipment on the range/efficiency of Peugeot e-208? (wheels especially) The advertised 340 km are probably not valid for all versions.
