No doubt the Ioniq’s shape is aerodynamically efficient. Other, less obvious tweaks for the sake of efficiency include plastic inserts between the spokes of the alloy wheels, creating a smoother surface without much extra weight, and vertical slots in the front bumper that create an “air curtain” to help reduce turbulence from the spinning front wheel.
Hyundai also says it has used high-strength steel for the structure, plus aluminium for bonnet and tailgate, to keep bloat at bay. With a kerb weight of 1,420kg to 1,475kg depending on specification the Ioniq EV seems fairly lean compared to Nissan’s Leaf, which weighs about 55kg more across roughly equivalent trim levels.
Under its skin the Ioniq Electric has a 28kWh lithium-ion battery housed below the rear seats and under the boot floor. This means that while the hybrid Ioniq has space for a spare wheel, the electric version must make do with an emergency inflator.
