EV4 estimated average
These curves are aggregated, owner-reported degradation data — not official manufacturer figures. Your own result above is the number that matters.
Wh/mi or Wh/km
On the infotainment screen, navigate to "EV" → "Energy Information" (or "Energy Consumption"). Average Wh/mi or Wh/km is shown in the consumption graph/table.
Estimated Range
Estimated range appears on the instrument cluster behind the steering wheel and in the EV menu on the central display.
Battery Percentage
Battery percentage is displayed on the instrument cluster (digital or analog gauge) and at the top of the EV menu screen.

About the Kia EV4
The Kia EV4 slots below the EV6 in Kia's electric lineup, offering a compact electric sedan and hatchback aimed at making Kia's EV technology more accessible. Available in two body styles — a conventional hatchback and a sleek fastback — it targets buyers who want an efficient, well-equipped EV without the premium pricing of the EV6.
Two battery sizes are offered: a 58.3 kWh pack delivering up to 273 miles of WLTP range, and an 81.4 kWh pack extending this to an impressive 388 miles. The single front motor produces 204 bhp, providing adequate but not thrilling performance. Notably, the EV4 uses a 400V architecture rather than the 800V system found in the EV6 and EV9, which limits DC charging to 135 kW.
The interior follows Kia's current design language with a dual-screen dashboard, clean lines, and a good amount of standard equipment. The hatchback body style offers practical boot space, while the fastback prioritises sleek styling over outright luggage capacity. Build quality matches Kia's consistently high standards.
The EV4 represents Kia's push to make EVs affordable and practical for a wider audience. While it lacks the headline-grabbing charging speed of its 800V siblings, the strong range figures and competitive pricing make it a compelling alternative to the Volkswagen ID.3 and MG4.
What the press thinks
The EV4 earns praise for its strong range figures, particularly with the larger battery, and competitive pricing. The dual body style option is appreciated. Critics note the 400V architecture limits charging speed compared to pricier Kia EVs, and the driving experience is competent rather than exciting.
