(SEOUL) October 14, 2026 – The Kia EV4, Kia's first dedicated all-electric sedan, has earned a five-star Green NCAP Sustainability Rating with a 90% overall score, the highest among all seven vehicles assessed in the latest test round.
Tested in Earth trim with an 81.4 kWh battery, the EV4 achieved strong performance across all three environmental indices: Greenhouse Gases (9.5/10), Energy Efficiency (8.9/10), and Clean Air (8.8/10). Green NCAP attributes this to the vehicle's efficient powertrain, European Slovakia production, and clean regional electricity mix.
“The Kia EV4 successfully introduces long-range EV capability from the premium into the mainstream family-car market. Green NCAP found the vehicle offers consumers high efficiency and excellent range under a variety of driving conditions,” said Dr. Aleksandar Damyanov, Technical Manager Green NCAP.
“We applaud Kia for producing this model in Europe which further reduces its environmental impact. A 5-star sustainability rating for a vehicle of this size and class is a real achievement.”
Why did the Kia EV4 earn five stars from Green NCAP?
Green NCAP’s assessment examines a vehicle’s environmental impact across its lifecycle and evaluates its real-world usability. The EV4’s 90% overall score reflects strong performance across energy efficiency, greenhouse gas impact and lifecycle environmental assessment criteria.
The tested EV4 is built in Slovakia. Green NCAP used European production parameters in its lifecycle calculation, and noted that European production a relatively clean regional energy mix contributed positively to the EV4's lifecycle assessment result.
Green NCAP highlighted the EV4's efficient powertrain and low electricity consumption across multiple test conditions, including 13.9 kWh/100 km in summer on-road testing.
Which charging features did Green NCAP highlight?
The EV4 offers manual and automatic battery preconditioning to optimize charging. Green NCAP reported DC fast charging starting at up to 130 kW, tapering toward the end of the charging process to protect battery health.
The assessment also noted the EV4’s bidirectional charging capabilities, adding to the vehicle’s everyday versatility.
What does this result mean for Kia?
The five-star result provides independent recognition of the EV4’s environmental performance and its ability to support everyday electric driving. It reflects Kia’s focus on developing electric vehicles that combine energy efficiency with practical usability.
“Like all Kia EV models, the EV4 was developed to make electric mobility both more practical and more sustainable for everyday use,” said Sang Un Cho, Senior Vice President and Head of Global Business Planning Sub-Division at Kia Corporation.
“The five-star Green NCAP rating provides valuable independent recognition of the engineering that has gone into the EV4's energy efficiency, real-world driving performance and lifecycle environmental impact.”
What does Green NCAP assess?
Green NCAP evaluates vehicles across Clean Air, Energy Efficiency and Greenhouse Gases, using laboratory and on-road testing. Its Sustainability Rating considers whole-life environmental impact, while its assessments also examine practical factors such as driving range, charging and cold-weather performance.
The latest assessment round included electric, hybrid, gasoline and diesel vehicles across seven models tested. Among all vehicles evaluated, the EV4 recorded the highest overall sustainability score.
