REAL LIFE. REAL TRAFFIC. REAL GREEN.
"ECOBEST Challenge is the first European independent test on the most popular EV’s on sale in Europe. The testing methodology is consistent and unbiased, pioneering the `human random factor`, the closest concept to the ideal `average customer`! AUTOBEST introduced a number of proprietary indexes, easy to be understood by all the consumers around the world. It is about real range, real charging process both AC and DC , about energy efficiency spent on board and `life after death` of the battery indicating ZERO on the cluster. All the results are introduced without any ranking or comments. Our mission is to serve the millions of motorists looking to see facts and figures, real measurements coming from real driving habits, real traffic testing. ”
With the aim of informing, guiding and advising European car users about the true efficiency and use of the latest pure electric cars, the AUTOBEST international independent organization has performed end of May 2025 a new edition of its ECOBEST Challenge. 15 new EV’s from 15 different manufacturers were evaluated under true real life, real traffic, similar and reproductible conditions and went through 7 different kinds of tests, which results are of greatest interest for users of electric vehicles.
The most striking surprise of this year probably comes from Leapmotor T03, which delivers an incredible EcoC 1 index of 109.43% (EcoC 1 = ratio between real driving range and WLTP range)! This means that its real range is substantially higher than the official WLTP figure. This is unique in the ECOBEST Challenge history.
Our tests also revealed interesting improvements in terms of energy efficiency (EcoC 2 index = how many km of real driving range is provided by 1 kWh of battery). The absolute highlight is the excellent performance of DACIA Spring, which boasts a stunning 8.17 km/kwh, an all-time record for our proprietary index EcoC 2. It was closely followed by Leapmotor T03 with 8.06 km/ kWh. Another tested model managed to cover more than 7 km/kWh. Three cars above 7 km/kWh, this is another first. Just two years ago, we were reporting the fact that six cars out of 14 could cover more than 6 km/kWh, now it has become the norm: in 2025 only two out of 15 do not get there!
ECOBEST Challenge, organized annually by AUTOBEST, is the original European independent real traffic test of mainstream EVs that reveals their true green credentials. It remains the only test of its kind with a transparent, neutral and balanced approach. The event aims to provide clear information about electric vehicles and to raise public awareness about the benefits of transitioning to environmentally friendly motoring.
The ECOBEST Challenge 2025 takes place between May 26th – 28th, 2025, in Vairano, Italy.
Ecobest Challenge 2025, now in its 6th edition, further exemplifies AUTOBEST’s unwavering commitment to showcasing the genuine green credentials of mainstream electric vehicles.
As the first independent European real-world traffic test of its kind, this event underscores our dedication to providing transparent and credible information to the 665 million car users across Europe that AUTOBEST serves.
The ECOBEST Challenge is certified by BUREAU VERITAS for the third consecutive year, earning global recognition for its innovative and consistent methodology. The certification underscores the event’s commitment to providing genuine, comprehensive, and unbiased green credentials of electric vehicles (EVs) in real traffic, real life, real green conditions.
With ECOBEST Challenge, our organization is making one bolder step to serve the European motorists, delivering key information about the real range, energy efficiency and more about the most popular EV’s on the market. Our aim is to offer an independent test, where all the cars are driven in the same time, on the same route by different drivers, coming this year from 13 countries.
In 2009 AUTOBEST launched ECOBEST Challenge project, as a world’s first project for measurements of consumption, CO2 emissions, pollutants and micro particles. ECOBEST Challenge was launched years before Diesel gate scandal, with the aim to give consumer real data in real life traffic.
