Several tests have said that the quality on the outside and especially inside is on par with the German premium brands, if not even higher.
I can confirm that. Incredible for this price.
At 2.4t it's not a corner-carving car. Still, the driving performance is impressive. Compared with my Tiguan Biturbo 240PS, fuel/charging needs have been cut in half.
Consumption and range always depend on the driver. Whether electric or internal combustion. Anyone who drives an EV changes their thinking. Charge when possible, not always only when necessary. Many supermarkets, McDonald's, etc. already have charging options. While eating or shopping, plug in, done. The car is parked anyway. No extra time!
If I think just of the DSG start with that one-second hesitation... that doesn't exist with an EV.
You have to experience it. You don't need 500 hp for that.
I drive the BYD Sealion 7 'Excellence' and I'm mega satisfied

A much better vehicle than the 6. It beats it in practically every area. Faster, more room inside, better trunk, more comfortable

range that I can always charge to 100% — unlike other brands that told me it was recommended to stop at 80%, which consequently cut my real range from 600 to 480 by not being able to charge to 100%. I think that's something people should know.
