AI generated from our expert reviews

If you need to carry more than five people or pull heavier loads, the MG S9 has an advantage over the BYD Seal U because it comes with a third row of seats and can tow more. In both cars, you will barely notice or hear the petrol engine when it kicks in, though over-the-shoulder visibility could be better in the MG and is poor in the BYD. The two differ sharply when you use their touchscreens. The Seal U features sharp graphics and responds instantly to your touch, while the S9 has dated graphics and feels dreadfully slow to respond. On winding country roads, the MG exhibits just a touch of body lean, whereas the BYD leans a lot in corners.
