The 'ECOBEST Challenge 2023, electrified by VINFAST' and supported by Quattroruote, is the first European independent real traffic test of mainstream EVs to reveal the real green credentials. It remains the only such test with a transparent, neutral and balanced approach. The results come from a consistent methodology of testing performed identically on all 14 cars. This methodology is inspired by the practical needs and driving behaviour of most European motorists, coming from the habits in their daily commuting.
It is not designed pro or con to any models or brands and is neither a typical motoring media comparative test nor a record-breaking range test or – by contrast – a rally speed test to check how agile EVs are. The ECOBEST Challenge states the results and does not comment on the differences between models in the test. The test results are available to European consumers as a basis for their decision-making process.
The best outstanding result of this edition is the all-time record for DC Fast Charging for only 4 min for 100 km! This result represents the proof that very soon will be no time difference between charging the battery and filling the tank!
At this ECOBEST Challenge edition, none of the 14 models in test surpassed the homologated range under the WLTP cycle. But 6 out of 14 of the mainstream EV cars achieved more than 90% of their homologated WLTP range in real driving conditions. And only 3 reached less than 80% of the WLTP range, a better overall result compared with last year edition of EcoC.
As the previous editions of ECOBEST Challenge proved, there is life in the battery after the cluster indicator is zero. 13 of the 14 cars demonstrated a strategic reserve of between 2 and an all-time record of 45 kilometers. Furthermore, only one car stopped once the battery indicator showed zero on the cluster.
With the ECOBEST Challenge, AUTOBEST uses two proprietary indexes. EcoC 1 representing the ratio between the real driving range and the WLTP range. EcoC2 states the actual energy efficiency of EVs, revealing how many kilometers of real driving range a specific car can provide from 1 kWh. The EcoC 2 is the most important expression of the energy efficiency of an EV.
With overall good results for EcoC 1 and for `EcoC 2`, this edition proves that most EVs are becoming more efficient with the energy stored in the batteries. Still, compared with 2021 EcoC 2 record of 8.07 km/kWh, the best result of this year is 7,76 km/ kWh, better than last year top 6.65 km/kWh. Six cars are exceeding 6 km/kWh. Two cars were unable to achieve 5 km/kWh.
AUTOBEST uses the EcoC 3 index as the ratio between the real energy charged into the battery and the official net capacity, a clear expression of the charging process's efficiency. To give an even better real-life perspective, we are also introducing a new index, EcoC 4, which measures the car's actual efficiency, taking into consideration the energy filled in the battery and not the net battery capacity as EcoC 2.
The 2023 edition marks a first, as the ECOBEST Challenge received Bureau Veritas certification – a global recognition of the genuine, comprehensive, and innovative methodology employed in testing electric vehicles (EVs) in real traffic conditions and assessing their real-life green credentials in an unbiased manner.
