BYD Seal 6 vs Kia EV4
Two electric Sedans go head to head. Which EV is the better buy for Australian drivers in 2026?
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.
Price Breakdown
The BYD Seal 6 starts from $34,990 before on-road costs, while the Kia EV4 opens at $59,190. That makes the BYD Seal 6 the more affordable entry point by $24,200.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $38,489 and $65,109 respectively.
Both models qualify for Fringe Benefit Tax (FBT) exemption, which is a significant advantage for salary-sacrificed novated leases. Depending on your tax bracket, this can save $5,000-$15,000+ per year compared to an equivalent ICE vehicle.
