I drive the 1.2 petrol hybrid from new since January 2026, which was registered in November 2025. Great car to drive. However, for tall person like myself, there is not enough room for your left keg to stretch and cramps happen in long journeys. Acceleration from start is better than my older 1.6 diesel c4 picasso. Overall best car I ever had, although infotainment a bit dodgy with a left hand and not at all practical. I minor inconvenience!

It's a pleasant car; it's not coarse or brutal. As a 60-year-old, I don't need acceleration or top speed.

Cars like the C5 Aircross are probably one reason why Stellantis is almost bankrupt — or already is.
Uncomfortable and completely unsuitable for long-distance driving.
Huge on the outside, small on the inside.
Extremely uncomfortable seats, poor infotainment, very bad driver aids (360° camera, cruise control, lane-keep assist, navigation… are really awful), confusing, poor road manners, loud engine and noisy wind.
I can only hope that I’ll never again be forced to drive this vehicle.

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

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.
