The independent body gave the efficiency results of 24 cars sold in Europe. A track record where the electric Zoe and Kona EV emerge victorious.
Created in 2018, GreenNCAP is the equivalent of EuroNCAP crash tests, but for the efficiency of cars. This independent organization has just delivered a set of results for 24 different models. Among them are the electric cars Renault ZOE and Hyundai Kona, which are better off the record.
The GreenNCAP scale gives a logical result of 5 out of 5 stars for these two vehicles. It focuses on three areas: air pollution with 5 categories of exhaust gases, consumption and greenhouse gases. Obviously, no gas is emitted by the electric motors, giving a completely green picture and 10/10 to the ZOE and the Kona in its 39 kWh version.
In the end, the two electrics are distinguished only by their consumption: 22.2 kWh / 100 km on average for the Kona and 22.3 kWh for the ZOE. The city car with the diamond tilts especially on the highway with an average of 29.8 kWh / 100 km against 27.2 for the Kona.
22.3 kWh / 100 km
22.2 kWh / 100 km
29.8 kWh / 100 km
27.2 kWh / 100 km
Hybrid: Japanese models in the lead
In addition to these two electric models, two hybrids occupy the prize list. The Toyota C-HR receives 3.5 stars for its 1.8-liter 122 horsepower version. The Japanese crossover stands out with little NOx but a lot of particles emitted. On the other hand, its average consumption is 5.4 l / 100 km, against 4.8 l / 100 km official WLTP. The Honda CR-V Hybrid 4 × 2 is satisfied with 2.5 stars. Japanese SUV is better than Toyota in NO emissionsx or N2O (nitrous oxide), but clearly worse in particulate matter and carbon monoxide (CO). Its measured consumption is however almost identical to that announced by the WLTP cycle: 6.9 against 7.0 l / 100 km.
Regarding thermals, some are rated better than the two hybrids. For example, the Mercedes C220d automatic (diesel) receives a 3 star rating, with good results except in particulate matter, N2O and CO2. Finally, the leader of the French market, the Peugeot 208, also obtains 3 stars with its 1.2 PureTech 100 hp petrol unit. On the other hand, it is less efficient than the Mercedes, because it emits too much CO and ammonia (NH3).
GreenNCAP also noted two natural gas cars. The Seat Ibiza 1.0 TGI CNG receives 3 stars, the Audi A4 g-tron only two. These engines particularly reject a lot of ammonia, particles and methane (CH4). Others miss the point, like the diesel Kia Sportage 1.6 CRDi 136 hp 4 × 4. The Korean is penalized by 1.5 stars, for consumption much higher than official values (6.9 vs 5.3-5.9 l / 100 km) and high methane pollution.
