About the C5
The Citroën C5 is a large family car that has been manufactured by the French car maker since 2000. A total of three generations have hit the market since that time.
The model was discontinued everywhere in the world apart from China in 2019. However, the nameplate saw a revival in 2021 for its third generation as the C5 X, not to be mistaken with the C5 Aircross.
The discontinuation came as a result of poor sales figures, likely due to the increasing trend of crossover SUV vehicles. However, Citroën saw this as an opportunity to bring the existing name back at a later stage for a new market.
A key difference for the third generation is the fact that the model pivoted to the mid-size crossover SUV class due to its huge popularity among consumers.
For the first two generations, it featured either a 4-door sedan or a 5-door station wagon layout. Of course with the change to somewhat of a mid-size crossover SUV for the third generation, it featured the typical 5-door layout found in almost all other models in the class.
Competition for today’s C5 X comes from the likes of the Mazda 6 Tourer, Volkswagen Arteon Shooting Brake, and Genesis G70 Shooting Brake.
The latest iteration features three trim options. These start with the base Sense Plus, Shine, and Shine Plus.
Both the first and second-generation models featured a variety of petrol and diesel engines, most of which were inline-4s with some V6 models. These engines typically ranged between 1.6 L and 3.0 L variants with most of the diesel versions offering turbocharged powertrains.
The latest version saw Citroën do away with all diesel options, instead offering two petrol engines and a single plug-in hybrid variant.
