Two electric SUVs 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.
Price Breakdown
The BYD Sealion 7 starts from $49,990 before on-road costs, while the smart #1 opens at $54,900. That makes the BYD Sealion 7 the more affordable entry point by $4,910.
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 $54,989 and $60,390 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.
