Tesla, NIO and Renault score highly in Green NCAP tests

Tesla Model 3, NIO eT7 and Renault Megane E-Tech score highly in Green NCAP tests

Green NCAP has published the results of three exciting electric vehicles: the Tesla Model 3, the NIO eT7 and the Renault Megane E-Tech. All three models, for their respective segments, have achieved excellent test results, with all three models scoring five stars.

Efficiency was the most notable feature of all three models, although other features such as comfort and power were also taken into account, particularly when travelling with them. Euro NCAP and Green NCAP Secretary General Michiel van Ratingen said:

“This latest round of Green NCAP tests clearly demonstrates that electric vehicles are an excellent choice for consumers in the quest for a cleaner and more sustainable environment. They score far higher than vehicles with conventional powertrains.

However, affordability remains a challenge. We call on manufacturers to further improve the efficiency of cabin heating in winter conditions, as it has been shown to have a significant impact on range. On-board charger efficiency is a hidden cost for consumers and here too the industry needs to strive for higher figures.”

Tesla Model 3

In the case of the Tesla Model 3, the rating is based on the 208 kW version with 60 kWh battery, single motor and rear-wheel drive. This is the first Tesla model to undergo Green NCAP testing, but that hasn’t stopped it from scoring well.

The Model 3 achieved high energy efficiency, not only in the WLTC+ hot and cold lab tests, but also in the road test, delivering a result, described as “very impressive”, of 21.1 kWh/100 km. More in detail, they explain:

“The small frontal area of the Tesla and its aerodynamic shape play in the vehicle’s favour, although in the WLTC+ test cycle at a winter temperature of -7 °C, due to the high demands of cabin heating, comfort and battery protection management, the consumption increases by 72% and the range is considerably reduced.

Despite this and the relatively high mass of the car, its result shows that it has been designed with a focus on efficiency and range.”

All in all, Green NCAP has awarded all five stars and rewarded the Tesla Model 3’s performance with an Overall Weighted Index of 9.8 out of 10.



Moving on to the Chinese electric NIO eT7, it leaves no one indifferent with this attractive 100% electric car coming to the European market. Green NCAP indicates that it is a vehicle “potentially aimed at Tesla lovers”.

The unit tested has a power of 480 kW, two motors and its corresponding all-wheel drive, as well as a large 100 kWh battery. All this gives it a weight of 2.4 tonnes, which obviously works against it when it comes to efficiency.

Even so, Green NCAP said that, in the WLTC+ laboratory test, the eT7 exactly met its claimed range of 580 km. And as for the weight we’ve been talking about, they said that “despite its high mass, the eT7 demonstrates high overall efficiency”. When the NIO eT7 is subjected to cold weather, in a temperature of -7°C, fuel consumption increases by 72%, which translates into an expected range of around 340 km.

The NIO eT7 achieved a five-star rating and was awarded an Overall Weighted Index of 9.6 out of 10.


Renault Megane E-Tech

Finally, there’s the Renault Megane E-Tech, the French brand’s 100% electric bet, which we at Somos Eléctricos have been able to test in detail, and we encourage you to check out our opinion of it for yourself, both the full test and the range test.

The version tested by Green NCAP is the EV60, which offers 160 kW and features a 60 kWh battery, a single motor and front-wheel drive. The values in the standard WLTC+ hot and cold tests are said to be “impressive”, but, as in the case of the NIO eT7, “increase significantly” in the road test.

The city driving results, they say, “are noteworthy”, with the Renault Megane E-Tech consuming just 11.8 kWh/100 km. In the laboratory test at -7°C, the vehicle’s consumption increased by 78% compared to the standard test and at 30 kWh/100 km is in between the measured values of the other two cars tested.

The Megane E-Tech scores 9.6 out of 10 points in the Overall Weighted Index, giving it a five-star rating.
