Selected trimStandard Range RWDChange trim273 mi · 63 kWh · £40,695
At a glance
Overview
The Hyundai Ioniq 5 and Kia EV6 share the same 800V E-GMP platform, so this is less about engineering and more about character. The EV6 is the longer-range, more driver-focused car with a sleeker profile; the Ioniq 5 trades on its retro styling, lounge-like flat-floor cabin and slightly lower price. Both charge quickly, so pick the one whose design and packaging suit you.

What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Shared watch-outs for both cars
Owners of every car here flag real-world range. Worth checking on a test drive whichever you choose.
Hyundai IONIQ 5
Standard Range RWD
Owners love
- Exceptional driving dynamics with outstanding handling, steering precision, and engaging performance that feels like a proper driver's car despite its 2.2-ton weight
- Cutting-edge 800-volt charging architecture enables industry-leading 350kW fast charging speeds, significantly faster than most competitors
- Impressive range with larger battery options (315+ miles WLTP) and strong real-world performance in various conditions
Watch out for
- Poor efficiency for its class, achieving only 2.5-2.7 mi/kWh in real-world driving, resulting in disappointing real-world range despite manufacturer claims
- Premium £65,000 pricing lacks competitive justification given interior quality comparable to standard Ioniq 5 and efficiency below competitor standards
- Known vulnerability to theft via programmable key exploits, particularly concerning in high-risk areas, with ongoing unfixed security issues
Owner tips
- Test drive extensively and set up suspension and drive modes (Normal suspension recommended for UK roads, Sport steering, Sport+ motor settings) to match your preferences before committing
- Budget for security upgrades like Ghost immobilizer in high-theft areas; check insurance quotes early due to known theft vulnerabilities
Kia EV6
Air 77.4kWh
Owners love
- Very fast rapid charging, with owners regularly seeing 200 kW or more on ultra-rapid chargers
- Comfortable, quiet and refined on long journeys
- Distinctive design that owners still like years on
Watch out for
- Failures of the ICCU (the unit that charges the 12V battery) are the biggest theme, covered by a UK recall, sometimes with long waits for parts
- 12V battery problems, often linked to the ICCU, can leave the car unable to start
- Mixed experiences of Kia dealers, with slow parts and patchy communication
Owner tips
- Check the ICCU recall has been done and ask whether the unit was replaced
- Ask whether the 12V battery has been tested or replaced

Frequently asked questions
Which is cheaper to own over 5 years, the Hyundai IONIQ 5 or the Kia EV6?
The Hyundai IONIQ 5 is £200 cheaper to buy. Running costs are almost identical - about £160 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the two land within £200 of each other - effectively the same to own. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Hyundai IONIQ 5 and Kia EV6 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 228 miles for the Hyundai IONIQ 5 and 273 miles for the Kia EV6 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Kia EV6 goes roughly 45 miles further between charging stops. Both rapid-charge to 80% in a similar time, around 18-18 minutes.
Which is easier to park and drive in town, the Hyundai IONIQ 5 or the Kia EV6?
The two are within 10 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 520 mm of total clearance for the Kia EV6 and about 510 mm of total clearance for the Hyundai IONIQ 5. The Kia EV6 also turns in a 0.4 m tighter circle, which helps with U-turns and multi-storey ramps.
Which battery will hold up better as a used buy, the Hyundai IONIQ 5 or the Kia EV6?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Hyundai IONIQ 5 and 89% for the Kia EV6. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
