Price Breakdown
The BYD Seal starts from $52,990 before on-road costs, while the Hyundai Sonata opens at $29,990. That makes the Hyundai Sonata the more affordable entry point by $23,000.
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 $58,289 and $32,989 respectively.
The BYD Seal qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Hyundai Sonata, as a petrol model, does not qualify.

Feature Showdown
Both come with modern infotainment systems.
The BYD Seal stands out with wireless Apple CarPlay/Android Auto, power tailgate and Dynaudio audio that you will not find on the Hyundai Sonata. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The BYD Seal uses a Electric producing 230kW and 360Nm of torque, sent through a auto to a RWD layout. It covers the 0-100km/h sprint in 5.9 seconds.
The Hyundai Sonata lines up making 138kW and 241Nm, paired to a 6-speed automatic driving the front wheels.
The BYD Seal has the clear power advantage at 230kW vs 138kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BYD Seal measures 4,800mm long on a 2,920mm wheelbase, 55mm shorter than the Hyundai Sonata at 4,855mm (2,805mm wheelbase). The longer wheelbase on the BYD Seal generally means more rear legroom.
For towing, the Hyundai Sonata leads with a 1,300kg braked capacity vs 1,000kg. That 300kg difference matters if you regularly hitch up.
