According to the International Council on Clean Transportation (ICCT) Global Automaker Ratings 2025, Tata Motors and Mahindra have emerged as the world’s most energy-efficient electric vehicle manufacturers, outperforming global giants such as Tesla and BYD.
The list evaluated 22 of the world’s largest manufacturers in its 2025 Global Automaker Ratings. The report measures several aspects of each company’s transition towards electric mobility. These include EV sales performance, manufacturing decarbonisation, feature readiness, and battery electric vehicle (BEV) efficiency.
In the comparison of energy efficiency, Tata Motors secured the top position globally. The ICCT highlighted that its adjusted energy consumption figure of 106 Wh/km was the best among all manufacturers. Mahindra Automotive followed closely in second place with 113 Wh/km.
Indian EV makers outperformed global leaders such as Tesla and BYD in energy efficiency, with Wh/km figures well below the global average of 131 Wh/km. Lower energy consumption per kilometre means vehicles use less electricity, improving efficiency while reducing both power usage and running costs for owners.
Incidentally, Tata Motors beat BYD by consuming an average of 106 watt-hours per kilometre (Wh/km), compared to BYD’s 120 Wh/km.
In 2024, Tata introduced new EV models that diversified its offerings. Tata and subsidiary Jaguar Land Rover also ramped up efforts in battery recycling and repurposing in major markets.
Geely and Chery, both in the Transitioners group, showed the most improvement in scores compared with 2023. Geely and Chery increased their ZEV-equivalent sales shares by 12 and 9 percentage points, respectively, while offering new models, and both shifted sales toward high-performing models that improved the average performance of their new BEV fleets.
Automakers based in Japan and the Republic of Korea still lag behind, but Honda and Nissan have made progress. Honda introduced its first BEV model, the Prologue, in the United States, and its sales led to substantial improvements in all BEV performance metrics for the company. Nissan strengthened its ZEV ambition by separating its 40% by 2030 ZEV target from a previously announced target that included conventional hybrid vehicles.
Meanwhile, you will see Tata passenger cars in Malaysia “very soon,” as the company’ looks to building a strong network with this Malaysian auto group that handles luxury and mid-segment vehicles.
More will be shared in coming months (before Q4 2026) once we get the go ahead from their their communication department.
