The test has been performed at the end of May 2025 as the new edition of its ECOBEST Challenge: 15 new EV’s from 15 different manufacturers went through 7 different kinds of tests which results are of greatest interest for users of electric vehicles. In a rigorous real-world test, the Leapmotor T03 emerged as a standout performer, setting new benchmarks in electric mobility.
A Historic Achievement in Real-World Range
The Leapmotor T03 made history by achieving an EcoC 1 index of 109.43%, meaning its real-life driving range exceeded the official WLTP range – a first in the history of the ECOBEST Challenge. The T03 covered an impressive 290 km, surpassing its WLTP-rated 265 km range.
Class-Leading Energy Efficiency
In the EcoC 2 index, which measures how many kilometers a car can drive per kilowatt-hour of battery, the Leapmotor T03 delivered a remarkable 8.06 km/kWh, placing it second only to the Dacia Spring and making it one of the most energy-efficient EVs ever tested in the Challenge.
Best Overall Real-Life Efficiency
Leapmotor T03 also topped the EcoC 4 index, which combines driving and charging efficiency, with a leading score of 6.89 km per real kWh charged—proving it to be the most efficient EV in terms of real-world energy use.
