Mercedes-Benz has revealed the first official photos and details of the new C-Class Estate, which is set to go on sale in the UK in September 2014.

The new C-Class Estate is 96mm longer and 40mm wider than the out-going model, with an 80mm longer wheelbase.

The company says this has resulted not only in greater passenger space, with 45mm more legroom for rear seat passengers, but also increased cargo capacity, with 490 litres available with the seats in place or a maximum of 1,510 with the seats folded.

Convenience is a strong-point for the new model, with rear seats that can be unlocked and folded electrically and a power tailgate that can be activated by waving a foot underneath the rear bumper.

Bringing it into line with recent Mercedes models, the new C-Class Estate features a large centrally-mounted touch-screen interface, and this couples with a head-up display that projects information about vehicle speed, road signs, and navigation instructions onto the driver’s field of view.

Despite the larger size and extra kit, Mercedes say the use of aluminium has helped achieve a weight saving of up to 65kg on some models when compared with the out-going C-Class.

The engine range is more efficient, too, with diesel options ranging in power from 115hp to 204hp.

A C300 BlueTEC Hybrid model will also be available, powered by a 204hp four-cylinder diesel engine mated to a 27hp electric motor, with anticipated economy of 74mpg on the combined cycle.

Three four-cylinder petrol units and one six-cylinder will also be offered, ranging in power from 156hp to 333hp.  A C350 plug-in hybrid with 208+67hp will follow later.

Suspension options include two steel specifications, plus the company’s AirMatic system.  4Matic all-wheel-drive will also feature on some models.

A series of modes – which encompass Comfort, Eco, Sport, Sport+ and a user-configurable Individual mode – allow the driver to customise their driving experience.

Pricing has yet to be announced, but the new C-Class Estate is expected to arrive in the UK this September.
