I drove the Mercedes EQS and the Xpeng G9 Performance. The Xpeng is an ultra-modern, voice-controlled car with excellent build quality, a superior sound system and air suspension. I now understand why VW invested €700 million to buy a 5% stake in Xpeng. VW cars in China now run on Xpeng technology.

I've seen and driven both cars. The XPeng 9 makes more of an impression. The Zeekr 7x's interior color is limited to black — a real shame! For a nicer contrast you'll have to have it wrapped in a different color. But that's a matter of taste! Otherwise the cars are comparable, noting that the XPeng is a proper SUV while the Zeekr 7x is a crossover.

I've done 6,000 km and I'm delighted. I haven't tried other EVs, but I'm thrilled with the BYD Atto 2. It's true I don't go on long trips — I do everything in the city and nearby, about 100 to 150 km a day — and honestly it's been great in every way. When I hit 300,000 km I'll tell you again. Haha
