TL;DR: The routeplanner is (quite) poor.

Pros

• The car charges fast (174kW peak and 12-80% in 23 minutes)
• The ADAS is good, apart from the non-capacitive steering wheel which needs pressure to sense your hand.
• The option adapt the speed to the current speed limit only works with lower speed limits rather than to increase the speed. However this quick setting only works for around 10s after it detects the lower speed limit and prompts the driver.
• The Leapmotor allows you to set automations in the infotainment e.g. close all windows when I exceed 100km/h (example shown)
• The navigation shows you a list of all nearby service stations with the services available as you drive along the motorway.
• Relatively quiet (66dB at 130km/h)

Cons:

• The routeplanner doesn't automatically add charging stations to the route, you have to tell it even though it will warn you that the range is insufficient.
• The routeplanner does not change the route after a charge, you must recalculate
• The routeplanner does not allow you to set a preferred charging provider (s).
• The routeplanner does not show a est. % at arrival at a charger or destination only the est. km. The routeplanner does not tell you how much you must charge to reach the next stop/destination.
• The routeplanner's consumption used for the chosen route & stops is not realistic based on previous consumption (too optimistic)
• The routeplanner does not adapt to an increased consumption.
• Preconditioning only functions automatically through the routeplanner, there is no manual option, so you're stuck with the poor built in routeplanner if you want preheating to work.

Trip Figures

• Consumption was good, 20.8kWh/100km on the motorway and 18.2kWh/100km in total (dual carriageway/motorway).
• Total time for 612km in 7h10 (43 minutes charging) 2x charges, trip started at 100% SoC.

NB: The title said 650km but the trip was only 612km.

Android Auto will get more personalisation options such as Wallpapers and Widgets, as well as more AI functionality. Perhaps most importantly Android Auto can now adapt its interface to completely fill unconventionally shaped screens such as the trapezoid screen in the BMW iX3 or the round screen in Minis.

Hyundai's Mobis division has designed a highly standardised 215hp motor that integrates the inverter, reduction gearbox and motor into a single casing resulting in a 20% lower volume compared to similar products.

Time 10h30

Tyres: Continental Eco Contact (Summer) 235/50 R18

Temperature: 4-13°C (Avg. 7°C)

Consumption: 274Wh/km

Unfortunately it looks like the thermal issues are still present, since the car is unable to sufficiently preheat the battery to achieve max speed (coldgate) and thermal throttles when hot (rapidgate)

Nonetheless the higher peak speed does allow the Atto 3 Evo to finish the 1000km challenge 1h10 minutes faster than the previous Atto 3 (11h40)

This is the second part of the Supertest of the Renault Twingo electric by French EV-site automobile-propre. The average ambient temperature during this test was 17.8°C

NB: As mentioned in the article, 11kW AC charging and DC charging capability costs 500€ extra.

The tested car in its Techno variant cost 21,090€

Charging Curve: 10-80% in 30 minutes (50kW max)

The Twingo can charge from 10-80% in 30 minutes, at a peak charging speed of 50kW. It's LFP battery only has a capacity of 27.5kWh (usable). The charging curve progressively falls-off and only pulls 24kW at 80%. 10-100% takes 66 minutes.

Interestingly with the battery at 42°C, the car accepts 37kW at 15% but falls rapidly to 24kW at only 35%, taking 53 minutes to charge to 80%.

Temperatures rise to 40°C during normal charging (first instance)

A problematic passive cooling system

To reduce costs, the Twingo comes with a passive cooling system, without active air circulation or liquid cooling. This means cooling of the battery is achieved solely via the air flow under the battery casing.

Thermal Throttling (Rapidgate)

Unlike La Chaîne EV which did not experience throttling at 110km/h, automobile-propre did experience significant throttling at 130km/h.

https://www.reddit.com/r/EuroEV/comments/1t8bemd/la_cha%C3%AEne_ev_600km_in_a_renault_twingo_electric/

This has two reasons, firstly driving faster demands more current from the battery generating more heat (the consumption is also significantly higher, 16.3kWh/100km vs 20.6 at a constant 110km/h vs 130km/h. Secondly, the battery has less time to cool down between each charging stop.

Throttling (examples)

• 1st charge: 10-80% 29 minutes (15-80% in 27 minutes)
• 2nd charge 15-80% 55 minutes

A-P theorises that if the ambient temperature is below 10°C, the car should not throttle, but above 20°C it would be best to not venture above 110km/h to avoid throttling. However, since the realistic range is so poor at 130km/h it's likely a better profile for long distances.

Charging Speed Problems with 50kW chargers

Thanks to the LFP cells which have a lower voltage, and the pack layout, the Twingo electric has a nominal voltage of around 300V. Thanks to the limited amps which a 50kW triple charger e.g. ABB Terra 54 CJG can provide (125A) this limits the max charging speed to only 39kW with such a charger. Although in practice this only makes a 2min difference. But be careful of blocking fees e.g. Total energies which kicks in after 45 minutes

A-P notes the flexibility of the old 22kW AC equipped Twingo.

100km of real motorway range charged in 30 minutes

The Twingo can only recover 100km of real world motorway range (130km/h) in 30 minutes

Time to cover 500km: estimated 6h25

Automobile-propre was not able to complete their typical Lyon-Paris test. However the Twingo's routeplanner indicated a time of 6h25 with 1h56 of charging.

For a real-world, check out La Chaîne EV's 600km test with the Twingo, which took 9h30 while trying to maintain 110km/h where possible. Including 1h58 of charging.

BYD's Blade Battery 'Leopard 3' reached a peak temperature of 76.4⁰C during megawatt charging, this has drawn concern due to the fact that it exceeds the Chinese safety guidelines for LFP cells, which indicate a maximum temperature of 65⁰C.
