Hyundai IONIQ 5 vs Kia EV6: Same Platform, Different Personality

The IONIQ 5 and EV6 share the same E-GMP platform, the same battery packs, and much of the same underlying engineering — yet they feel like genuinely different cars from behind the wheel. For NZ buyers deciding between corporate siblings, this comes down to character and priorities rather than hard technical advantages.

Price and specification (2026 NZ)

	IONIQ 5	EV6
Entry price	$69,990 (Standard RWD)	$66,990 (Air RWD)
Mid	$79,990 (Long Range AWD)	$76,990 (GT-Line AWD)
Battery	58 / 77.4 kWh	58 / 77.4 kWh
WLTP range	384 / 481 km	407 / 484 km
Max DC charge	230 kW	240 kW

The EV6 is slightly cheaper across the range and edges out the IONIQ 5 marginally on both range and charging speed for equivalent battery sizes, despite sharing near-identical underlying hardware — a reflection of its more aerodynamically efficient body shape.

Design and interior philosophy

This is where the cars diverge most sharply. The IONIQ 5 has a boxy, retro-futurist design with a completely flat floor and a sliding centre console that can move backward, creating a lounge-like front cabin. The EV6 is a swooping, coupe-like SUV with a sportier driving position and a more conventional (if still high-tech) dashboard layout.

Rear seat space clearly favours the IONIQ 5 — its flat floor and longer wheelbase create noticeably more usable legroom for adults in the back. The EV6's sloping roofline also costs some rear headroom that taller passengers will notice on longer trips.

Driving character

The EV6 is tuned to feel sportier — quicker steering response, firmer suspension, and the GT variant's genuinely startling acceleration make it the more engaging car to drive. The IONIQ 5 is tuned for comfort and composure, with a softer ride that suits NZ's patchier back roads better on long trips.

Charging network access

Both use CCS2 and are fully compatible with NZ's ChargeNet and other public networks. Neither has any brand-specific charging advantage in NZ, unlike Tesla's Supercharger network — so charging speed and availability come down to identical real-world conditions for both cars.

Running costs

	IONIQ 5	EV6
Electricity cost per 100km	~$3.70	~$3.55
Annual servicing	~$230	~$240

Effectively a wash — any difference here amounts to $20–$30 a year and shouldn't influence the decision.

Resale and dealer network

Hyundai's NZ dealer network is somewhat larger and more established than Kia's, though Kia has invested heavily in NZ over the past five years and its service reputation has improved considerably. Both brands offer strong warranties (5 years/unlimited km on the vehicle, 8 years on the battery for both), which supports resale confidence for either.

Verdict

Choose the IONIQ 5 if: rear passenger space matters, you prefer a more distinctive, lounge-like interior, and you value a comfort-oriented ride over outright dynamics.

Choose the EV6 if: you want a sportier drive, slightly better range and charging figures for the money, and you prefer a more conventional SUV silhouette.

Given how closely matched these two genuinely are underneath, we'd suggest test driving both back-to-back rather than relying on spec sheets — the character difference is real and will likely decide it for you within the first ten minutes behind the wheel.
