MG 3 Engines and Transmissions

The MG 3 engine offering centres on a hybrid setup, represented here by the 1.5 AT in Mini 5-doors form. It pairs petrol and electric power, sends drive to the front wheels, and uses an automatic transmission, so town driving needs no clutch work or manual shifting.

MG 3 Trims and Equipment

MG 3 trim levels sit on top of the mechanical package rather than changing it. The 1.5 AT hybrid is offered as Comfort and Luxury, which differ in convenience, comfort and interior equipment. Both share the same drivetrain, so the choice is about features you will actually use daily.

MG 3 Battery

MG 3 battery capacity matters mainly for how smoothly the hybrid works. The 1.5 AT uses a lithium-ion pack that stores energy recovered when you slow down, then releases it when pulling away or cruising gently. It charges itself as you drive, so no cable or socket is involved.
