Citroën, like most mainstream manufacturers, hasn’t produced a large family car in recent years, as buyers continue to embrace SUVs. The brand’s C5 X model aims to break the mould for what we expect of a large car, combining coupé styling with estate car practicality, plus a slightly raised driving position. Is it the ideal choice for families, or is it a contrived compromise? Find out in our Citroën C5 X Plug-In Hybrid (2022-) review.

The overall Which? test score is made up of the following star ratings, all determined by our rigorous lab tests.

How we test cars

6 Jun 2025

Ease of driving

Overall
Visibility
Smoothness of power delivery
Driving stability
Cabin layout

How we test ease of driving

To find out how easy a car is to drive, we assess cars across a number of areas from visibility and handling to the layout of the cabin and how smoothly the engine delivers its power.

Performance

Overall
In-gear acceleration
Brakes

How we test performance

We test braking distances and whether the effectiveness of the brakes fade with repeat use. Performance is based on in-gear acceleration.

Comfort and practicality

Overall
Entry and exit
Seat comfort
Ride quality
Quietness
Seat space
Boot space (large cars, SUVs and MPVs)

How we test comfort and practicality

Comfort and practicality includes how easy it is, or not, to get in and out of the car and the maximum height of occupants. We also measure road, wind and engine noise and assess how well the car deals with bumps from large potholes to jittery surfaces like cobble stones.

Euro NCAP

How we test euro ncap

Any car that receives a rating of two stars or less from Euro NCAP is made a Don't Buy. Any car that receives three stars can't be a Best Buy. If a car has been available for more than four years and has not been tested by Euro NCAP, it cannot be a Best Buy.

Safety kit

How we test safety kit

We factor in the safety equipment that’s factory-fitted or optional, along with how well the car protects its occupants and pedestrians in the event of an accident. We also test how easy it is to fit a variety of child car seats.

Brand reliability 0-4 years

Overall
Petrol reliability
Diesel reliability

How we test brand reliability 0-4 years

Our reliability ratings are based on the feedback from tens of thousands of UK motorists, as collected in our annual Which? car survey. We divide all reliability feedback into three age groups: cars aged up to four years, five to nine years, and 10 to 15 years.
