Feature Showdown
Both come with modern infotainment systems. Apple CarPlay and Android Auto are standard across both.
The Kia K4 stands out with wireless Apple CarPlay/Android Auto — features our data doesn't list for the MG MG3. The MG MG3 counters with Apple CarPlay and power tailgate. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Kia K4 uses a Petrol producing 110kW and 180Nm of torque, sent through a cvt to a FWD layout. It covers the 0-100km/h sprint in 9.8 seconds.
The MG MG3 responds with a Petrol making 81kW and 142Nm, paired to a cvt driving the front wheels. It gets to 100km/h in 10.8 seconds.
The Kia K4 has the clear power advantage at 110kW vs 81kW. In the 0-100 sprint (manufacturer-claimed), the Kia K4 is 1.0s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The Kia K4 measures 4,440mm long on a 2,720mm wheelbase, 327mm longer than the MG MG3 at 4,113mm (2,570mm wheelbase). The longer wheelbase on the Kia K4 generally means more rear legroom.

For towing, the Kia K4 leads with a 1,100kg braked capacity vs 500kg. That 600kg difference matters if you regularly hitch up.
