At 4.33m long, 1.79m wide and 1.49m high, new Citroën C4 is fractionally larger than its forerunner. Despite the model's compact external dimensions, there are generous internal volumes with extensive space and storage for all occupants, including the biggest boot in its class.

The raised dashboard architecture increases legroom for the front passenger and each front door storage compartment can accommodate a 1.5-litre bottle and miscellaneous A4-size documents.

The model's centre consoles come in four variants depending on the trim level and transmission - low, semi-raised, raised with manual gearbox and raised with EGS gearbox. All offer generous storage for drinks, mobile phones, MP3 players and other items. When combined with the EGS transmission, the raised centre console offers a large refrigerated and illuminated compartment that can be closed with a sliding shutter. Able to hold up to four 0.5-litre bottles, this feature is a first for the class.

Rear occupants also benefit from extensive space and storage with generous amounts of leg and headroom, which allows up to three adults to sit comfortably during longer journeys. Each rear door incorporates a storage compartment large enough for a 0.5-litre bottle and a paperback sized book. Most models feature front seat back pockets for additional storage and handy drawers positioned under the front seats.

With a capacious 380-litre boot - increasing to a maximum 408-litre VDA capacity (under the parcel shelf and utilising the under-floor storage compartment) - the new C4 offers the biggest boot in its class. The practical cubic dimensions and low, slim sill ensure ease of loading and optimal use of the available volume. When required, the split/folding rear seats can easily be tumbled forward to create additional load space up to the front seat backs.
