Citroen C5 Aircross

The Citroën C5 Aircross feels like a sofa on wheels, delivering a calm, floaty ride and clever packaging that makes life with luggage and kids noticeably easier. Quirky French styling and a supremely practical, family-focused cabin mean it quietly wins hearts by prioritising comfort over showroom bravado.

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.

I spent a weekend with the Brabus #5 and I’m thrilled! Extremely quiet, even at just under 220 km/h. Very good ride comfort, especially if, like me, you prefer a softer setup for better suspension comfort!
Brutal acceleration that only really hits from about 50 km/h and culminates in a 0–200 km/h sprint in 10.2 seconds… There are almost no cars up to roughly 1,000 hp that are faster!
The actual charging performance is, I believe, the best of any passenger car available in the EU (only Zeekr shows a little more on paper, but probably not in real life) — it charges at peaks up to 425 kW! 10–80% in 13 minutes and 5–100% in 28 minutes.
The fit and finish are in places better than the Mercedes E‑Class...

Apart from the hopefully soon improved/reduced chimes and the horrendously hard-to-reach mute for the speed warning, the car is really a knockout!
Very, very quiet, comfortable, extremely fast (Brabus version), great build quality, great equipment!
