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.

I find the Citroën better suited to my daily driving — more comfortable and efficient, with a softer suspension compared with the firmer Toyota Cross.
