Renault Twingo ZE gets official WLTP ratings
Renault Twingo ZE charging

Now that the Renault Twingo ZE appears at Renault’s German and French websites, we have the official WLTP ratings.

There’s good and bad news…

The bad news is that Renault’s on-board charger is still very inefficient at low currents. Charging at 10 amps has an efficiency of roughly 70 percent. To have a decent charging efficiency the current should be at least 16 amps, with 32 amps being recommended. Have this in mind when you choose an EVSE (Electric Vehicle Supply Equipment) if you have an electric car made by Renault.

The good news is that the WLTP range is higher than was previously estimated by Renault. The WLTP city range is increased from 250 to 270 km and the WLTP combined range is increased from 180 to 190 km.

While still low, it’s always nice to see a bit more range.


How does the Renault Twingo ZE compares to VW’s cheapest alternative, the SEAT Mii electric?


Renault Twingo ZE

  • WLTP combined range: 190 km (118 miles)
  • WLTP city range: 270 km (168 miles)
  • WLTP efficiency: 16 kWh/100 km (charging losses included) and 11,2 kWh/100 km (without charging losses)
  • Total battery capacity: 22 kWh
  • Usable battery capacity: 21,3 kWh (97 %)
  • Charging efficiency (at 10 A): 70 %
  • Motor: 60 kW


SEAT Mii electric

  • WLTP combined range: 259 km (161 miles)
  • WLTP city range: 358 km (222 miles)
  • WLTP efficiency: 14,4-14,9 kWh/100 km (charging losses included) and 12,47 kWh/100 km (without charging losses)
  • Total battery capacity: 36,8 kWh
  • Usable battery capacity: 32,3 kWh (88 %)
  • Charging efficiency (at 10 A): 87 %
  • Motor: 61 kW


Notice that WLTP efficiency ratings include charging losses and are made at 10 A charging, which doesn’t help the Renault Twingo ZE. However, if you charge at 32 A the Renault Twingo ZE is more efficient than the SEAT Mii electric.

Unfortunately the Renault Twingo ZE and the VW electric triplets are only considered as backup plans by their makers. They are the electric cars that Renault and Volkswagen will eventually try to sell only if the sales of the more profitable ZOE and ID.3 aren’t enough to meet EU emissions targets…

With poor ICE (Internal Combustion Engine) car sales this year they aren’t needed to meet those targets, that’s why price and availability are so lousy for these electric cars right now. This will probably change next year when ICE car sales are up again and automakers will have to sell more electric cars to reduce the emissions of their fleets.

Anyway, a new generation of the Renault Twingo ZE will arrive in 2022 with more range and definitely with a better price.

Thanks for the info.
As for the numbers for the Mii electric:
2.59*12.9=33.4 kWh from wall into 32.3 kWh usable or 97% charging eff.
Something seems wrong here, no typo in the fata?

The 12.9 WLTP effociency seems very low.

Hi Giora.

You’re right, the German and Norwegian websites of SEAT quote different figures.

SEAT Germany: 12,9 kWh/100 km
SEAT Norway: 14,4-14,9 kWh/100 km

I’ll revise the article and use the Norwegian figure instead. We get a charging efficiency of 87 % for the SEAT Mii electric, which seems plausible.

Thanks for the heads up.

WLTP combined range: 190 km
only discourages us.
Are the European automakers short of batteries. May be the upcoming giga battery factories could help.

VW deliveries of ID.3 starts in early september. Lets hope this brings a new dawn for BEV.

Good city car if it was priced correctly.
Pedro, how can I obtain the charging efficiency for other models? Is there a database?

Hi Rodri.

You can calculate it if you know the usable capacity, range and efficiency.

Renault Twingo ZE:

16 x 190 / 100 = 30,4 kWh (it takes 30,4 kWh from the socket to put 21,3 kWh in the battery)

Charging efficiency: 21,3 kWh / 30,4 kWh = 70 %

SEAT Mii electric:

14,4 x 259 / 100 = 37,296 kWh (it takes 37,296 kWh from the socket to put 32,3 kWh in the battery)

Charging efficiency: 32,3 kWh / 37,296 kWh = 86,66 %

Nonetheless, if you charge Renault electric cars at 32 A, the charging efficiency is normal. It’s only very low at 10 A.

Ok, so charge and low amps is still a problem. Did they at least solve problems with discharging (and with that unnecessary loosing of much needed power when on a longer trip)? Much of tests you can find on youtube/medias are just about the car in general and how it drives and not about detailed infos like that

So they (Vw and Renault) don’t want to sell their own electric cars

Why is that?
Is it only because margin per car is lower?
Or there’s more?

Hi Pit.

Automakers already invested a lot of money in production lines for their ICE cars, they want to milk the cow before it dies. That’s why they prefer a slow transition to electric cars.

I’m sure that for example the new Renault ZOE is much more profitable right now than its ICE counterpart (Renault Clio) and Renault does seem happy to sell this model at the current overpriced price. It’ll be the same for Volkswagen with the ID.3, it’ll be much more profitable than the Golf, but Volkswagen also wants a slow transition.

Hi Pedro, I never commented before but felt I needed to this time.
Wanted to thank you for highlighting, stressing out and constantly reminding what other websites won’t: the strategies of the OEMs regarding these segment vehicles. Thanks to you, everything makes way more sense as to why we have piss-poor offer for small city cars and virtually no available cars when wanting to order one. If this is all part of a plan B for lowering their CO2 emissions, I am hopeful 2021 will be very different in terms of availability, and probably MSRP prices offered by Renault and VAG on these vehicles. Plus, the EU supercredits for BEVS will get lower and lower until 2023 which I now believe will be a great year to finally switch to electric. Please correct me or add you insight if you want. Thanks for your reporting and expertise, always a pleasure to read!

Thanks Afterburner.

I think that’s pretty obvious what legacy automakers are doing, but bigger websites have to be nice to them so they get access to roundtables and interviews. That’s why they often buy into their BS narratives without questioning them, saying they are losing money with electric cars, need government subsidies and transition could happen but requires a new battery technology (that is always some years away)…

From a technological point of view, CTP (module-less) cobalt-free batteries is all that was needed to start the massification of electric cars. Chinese companies already have that.

I think that 2022 will be the year of the big push for electric cars. Only thanks to Chinese companies we now have affordable solar panels, it will be the same for electric cars. As an European this bothers me, but it’s the reality.

HOLA, estoy completamente de acuerdo a lo que dices.
I completly agree what you comment. They just try to avoid punishes via taxes…

THank you very much for your detailled reply, appreciated it a lot!
Keeping my eyes peeled for future announcements and price fluctuations for EVs in the next couple of years here in France. Canot wait to finally make the switch, but not at a price where OEMs are clearly making huge profits on affordable to manufacture battery packs, at my expenses!

Before anyone trying to buy a Nissan, Honda or Mitsubishi vehicle, please read this.
Japanese government officials tried to push for Honda-Nissan merger to ensure that nissan remains 100% in japanese hands. Had this happened, Ariya, Leaf and Outlander-PHEV would have been in trouble with Honda dead against BEVs.
If japanese dont want any foreign presence in their country, why should we buy their vehicles.
