- I show you how to drive the Dacia Spring electric in the most efficient way, including one thing most people won't think about when it comes to eco-driving.

Really nicely put together video, full of useful information. One thing that is underestimated with EV efficiency is tyre pressure, particularly at lower speeds. Most tyres these days can be safely run at 2.8 bar, which will gain at least 5-10% extra efficiency. The lower tyre pressure recommended by the tyre manufactures increases wear, so the tyres need replacing more often (hence the recommendation). Our Kia EV came with tyres inflated to 2,8 bar from the dealer and it runs and drives far better than the 2.4 bar recommended by the tyre manufacturer.
I know its a late comment but a lot of people swapped the factory wheels to a little bit bigger renault ones and they helped as well including traction.
Thanks for the very detailed testing! It is very useful to know. I am not an electrical engineer but from theoretical point of view if the motor can produce about 30 kW power and battery can be charged by peak 30 kWh then potentially could be solved to brake the car by about 30 kW (if cells can be charged with same current as they discharged and motor could produce the same current as that is use-up for driving) The only blocking point could be if the battery is cold or hot or close to full then that cannot be charged so fast so I suppose that engineers did not want to confuse customers with different braking drags depends on battery status. So they have chosen the minimum nearly always available braking drag.
But anyway if we will get our Spring in spring I will tell to my wife to use the brake as less as possible :-)
Hi Gabor, you'll find different charging speeds while driving with almost all cars, but with most others you don't realize it as you mostly stay below the slowest charging speed (the only case so far I have noticed it was with Renault Zoe, which tells you that charging is restricted). This can easily be solved as the friction brakes could be used to compensate for the missing recuperation (is it does in Zoe). The main problem here is, however, the maximum output of the motor, which is c. 26 kw for braking (and 33 for driving). For a short period of time the charging power can exceeded, but the engine doesn't produce enough energy.
Less braking is always more efficient than more braking ;)
even with stronger cars

@@ecodriver1746 I wanted to tell that Dacia engineers left some potential in theirs solution in my opinion.
In case of internal combustion engine cars brake disc heating is a clear wasting of energy. But electrical transformation of kinetic energy is also not 100% efficient.
Very interesting! Thanks
You're welcome!
wise test set up and evaluation perspective is crystal clear, thnks a lot.
You're welcome!
Hi. You have very interesting and real life situation tests, but I spotted one mistake on all videos I watched (I didn't watch them all yet). When you convert from kWh/100 km to miles, your number is for 1 mile, not 100 miles.
Keep up the good work.
Hi, thanks.
I know, I realised that recently myself and it will be corrected with the next videos. It's caused by the fact that we here always use 100 kms as a reference and this just slipped in.
Great test! But how do you estimate the consumption would be in summer time in 20-23 C on the same tour?
I guess around 9,0, maybe just a bit below.
Thank's for your great videos!
If you still remember, is it possible to coast with Dacia Spring?
What's the difference between coasting and rolling in neutral?
The Dacia Spring will coast if you release the power pedal. It only regenerates if you touch the brake pedal. There is no difference in coasing in neutral or rolling in neutral. However, it is not advisable to put the "gearbox" in neutral as it decouples the drivetrain. That clutch is not made to couple and decouple when the wheels are rolling.
güzel video fakat dilinizi anlamadığım için tam olarak sonucu anlayamadım. kısaca; ekonomi mod ile en fazla kaç km menzil gidebilir bu araç?
Merhaba, teşekkürler, 200 km'de kolayca mümkün olmalıdır. Sadece şehirde sürdüysem, belki de yaklaşık 300 km.
Is there a way to see when you start braking by friction? Is it a transition you feel? Or can you visually see it. Do you still "recipurate?" When you start braking with friction?
Hi, with this car you see it on the gauge, which has only 3 sections and its indicating when you reach the maximum, I feel it on the pedal, the feeling changes a bit when the friction brakes come on and there is a setting for the central display, where you can see the power needed and produced, once you hit 25-26 kW when braking you know thats the Maximum.
Nice video
Thanks.
What is your estimate of highway range? Same weather, 120 km/h.
I guess consumption will go up to 16 kwh/100 kms, so 160 kms/100 mls.
@@ecodriver1746 Thanks
How to see the kWh/100km on the dashboard? :D
Just press this black button on dashboard - there's only one
