The BYD Seal stands out with wireless Apple CarPlay/Android Auto and Dynaudio audio — features our data doesn't list for the Hyundai Sonata. The Hyundai Sonata counters with Apple CarPlay, head-up display, wireless charging, panoramic roof, heated front seats, ventilated seats, Bose audio and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Interior trim differs: the BYD Seal gets leather upholstery while the Hyundai Sonata offers suede & nappa leather.
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 BYD Seal has the clear power advantage at 230kW vs 213kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

The BYD Seal measures 4,800mm long on a 2,920mm wheelbase, 110mm shorter than the Hyundai Sonata at 4,910mm (2,840mm wheelbase). The longer wheelbase on the BYD Seal generally means more rear legroom.
