Kia EV4 Offers the Longest Range in the Kia Lineup

Kia EV4 offers the longest range in the Kia lineup, and it’s just the beginning

Kia is redefining what everyday electric driving can be with the launch of the EV4, a compact all-electric car engineered for endurance, efficiency, and confidence over long distances.

Built around Kia’s latest battery technology , the EV4 combines the longest range in Kia’s lineup with fast charging speed and battery management designed for real-world durability.

Recent tests that pushed the EV4 well beyond typical daily use have proven that electric cars can be as dependable in year eight as they are on day one.

How long do EV batteries last?

Electric car batteries are designed with longevity in mind, often lasting around 10 years or 100,000 miles or more before showing any significant decline in performance.

Most modern EVs have an average range of 100 to 300 miles* per charge, depending on the model and battery size. Proper battery management and regular charging help ensure consistent performance through the battery’s lifespan, reducing the need for early replacements and minimising long-term costs.

Battery technology built for the long road

At the core of the Kia EV4 is the fourth-generation battery system that offers a range up to 388 miles*. It’s the most advanced ever fitted in a compact Kia electric vehicle , combining sophisticated thermal management with optimised coolant distribution across every cell unit.

That means the EV4’s battery stays within safe temperature limits, even when operating under high stress, such as rapid acceleration, heavy payloads, or repeated fast charging . By controlling these temperatures, this not only protects the battery from premature wear but also ensures consistent performance in challenging climates.

The EV4 also benefits from precise cell balancing, which helps every cell in the battery pack contribute equally to the car’s output. Such careful energy management means drivers can expect extended battery life, even after years of use.

Tested beyond the everyday

Kia didn’t stop at lab simulations when testing out the EV4's durability. It has been proven in a series of rigorous trials designed to replicate extreme real-world demands.

· 110,000-kilometre Europe public road simulation – These represented years of daily driving compressed into months of constant testing.

· 10,000-kilometre Nurburgring campaign – The EV4 was driven at 90-95% of its maximum performance output.

· Repeated hyper charging sessions between laps – This deliberately added stress to the battery system.

Despite the punishing conditions, the EV4’s battery demonstrated minimal wear. Engineers measured a battery State-of-Health (SoH) of 95% after testing, providing clear proof that the EV4 can withstand far more than typical daily use.

Regenerative braking for added efficiency

In addition to its robust battery design, the EV4 features regenerative braking technology that captures energy during deceleration. In real-world driving, this can recoup up to 25% of the vehicle’s energy, reducing strain on the battery and extending the car’s range between charges.

This system works seamlessly in the background to help drivers go further without changing their driving habits, whether it’s stop-start urban traffic or a winding downhill road.

Why does long range matter?

For many drivers considering the switch to electric, range anxiety remains one of the biggest barriers. Kia’s approach with the EV4 tackles that concern head-on.

By combining range with proven long-term battery health, the EV4 offers reassurances for:
· Commuters : People travelling to work who need consistent performance in all weather conditions.
· Fleets : Vehicle downtime and battery degradation can directly affect operating costs.
· Weekend travellers : Those who want the freedom to explore without carefully plotting every public charging stop.

The EV4 is an electric car designed not just to meet its official range figure when new, but to maintain that capability after years on the road.

Designed for lasting ownership

Kia’s commitment to durability is backed by a guarantee that the EV4 will retain at least 70% of its battery capacity after 100,000 miles or eight years of use.

That’s not just a term built into Kia’s electric car battery warranty. It’s a reflection of the confidence in the EV4’s engineering, as well as being a statement about what the future of electric mobility should look like.

“The EV4 had to prove itself not only in the lab, but in the toughest real-world and extreme environments,” explains Stephan Hoferer, Manager Durability Development at Hyundai Motor Europe Technical Center. “From icy roads to racetracks, we’re confident the EV4 will deliver dependable performance well beyond everyday needs.”

For owners, that means fewer worries about long-term performance and more trust that their EV will continue to deliver efficient and enjoyable driving well into the future.

* The range was determined according to the standardised EU measurement procedure (WLTP) on EV4 Air Grade. The individual driving style and other factors, such as speed, outside temperature, topography and the use of electricity-consuming devices/units, have an influence on the real-life range and can possibly reduce it.
