How much autonomy offer electric cars more popular when tested in the real world? The answer comes from road test comparative organized by the Norwegian Automobile Federation (NAF).
The test involved 21 models among the most popular, currently on the market, to compare the data for the declared autonomy in WLTP homologation cycle – Worldwide harmonized test procedure for light vehicles, the new standard from 2017 – with those derived from real use.
As we know, there are several factors which affectautonomy of electric cars. With regard to cars a heat engine that driving style plays a very important role: sudden accelerations and very high speeds cause the charge to drop rapidly, also because the car in these situations can not take advantage of regenerative braking.
Self trip plays a fundamental role, electric cars weigh more than straight segment thermal engine due to the bulky goods drums mounted in the floor; that means tackling parts of the road in steep slope it will increase energy consumption significantly.
Attention, then to the weight of loads transported which forces the electric car engine to load and to extra consumption especially in restarts or in the sections raised one high speeds.
Last but not least is another factor affecting autonomy external temperature. Various Education confirm that winter temperatures reduce autonomy of electric cars by about 15%, while the high temperatures of the summer months by 10%.
The final ranking of electric cars with more autonomy
Shows, in detailshow they behaved and how many kilometers the singles drove car under test in the final ranking:
- Mazda MX-30: 219.6 km in test (200 km WLTP)
- Honda e: 236.2 km in test (210 km WLTP)
- Electric Fiat 500 icon: 307.8 km in the test (298 km WLTP)
- Opel Mokka-e: 332.4 km in the test (324 WLTP)
- Citroen e-C4: 345 km in tests (350 WLTP)
- Volkswagen ID.3: 421 km in tests (418 km WLTP)
- Xpeng G3: 438.9 km in the test (451 km WLTP)
- Volvo CX40 Recharging: 442.9 km in the test (417 km WLTP)
- Mercedes EQA: 451 km in the test (417 km WLTP)
- Polestar 2: 467 km in the test (470 km WLTP)
- Hyundai IONIQ 5: 502 in test (460 km WLTP)
- Skoda Enyaq: 522 km in the test (520 km WLTP)
- Audi e-tron GT: 528.1 km in the test (468 km WLTP)
- Volkswagen ID.4: 532 km in the test (487 km WLTP)
- Ford Mustang Mach-E AWD with long range: 551.9 km in test (540 WLTP)
- BMW iX3: 556.2 km in the test (450 km WLTP)
- Volkswagen ID.3 Pro S: 564 km in tests (539 km WLTP)
- Hyundai Kona Electric 2021: 573 km in test (484 km WLTP)
- Tesla Model 3 LR (2020): 612 km in test (560 km WLTP)
- Ford Mustang Mach-E Long Range RWD: 617.9 km in test (610 WLTP)
- Tesla Model 3 LR (2021): 654.9 km in test (614 km WLTP)
The test with 21 electric cars
To get one classification as accurate as possible all cars drove on the street a charged batteries at the same time with an outside temperature between 20 and 25 degrees. Each car also held air conditioning set to the same temperature and intensity.
The test pressed each of the 21 electric cars involved up to its limit. Every driver did not stop driving until the car did used the battery and went out. The cars went through the same thing test course which included urban, suburban and motorway sections but also a small mountain pass to verify the effects of change in height.
Reading in detail of data collected by sample it only emerges 3 cars they failed to do better than the data stated in WLTP authentication: Polestar 2, Citroen e-C4 and Xpeng G3 have lost 3, 5, 11 km autonomy in relation to the declared. All in all, it’s about reasonable numbers if we consider the use under real driving conditions and the fact that they continue to place well in final location overall independence.
Electric car autonomy: Tesla ahead, but not too much
What happens when the remaining battery life character 0? The test confirms that electric cars can perform better than specified in the WLTP homologation cycle and continue to travel at least a few kilometers. There Tesla Model 3it has traveled, for example 48 km before it stops completely.
Tesla Model 3 Long Range wins the challenge between electric cars with 653 km autonomy against the 611 km specified in the homologation. First among the persecutors Ford Mustang Mach E with a total autonomy of approx 617 km against about 610 in the WLTP cycle.
Looking at the final classification, the execution of BMW iX3 which beat its nominal area by approx 106 km with a 20% improvement compared to the WLTP authentication.
