The first official photos and details have been revealed of the new Citroen Grand C4 Picasso.

Based on the EMP2 (Efficient Modular Platform 2) but extended to provide a 2.84m wheelbase, the new Grand C4 Picasso offers full seven-seat capability with optimised door apertures and an extra 69 litres of boot space over the outgoing model.

The new platform uses aluminium and steel construction with a composite rear floor, aluminium bonnet and composite tailgate, leading to weight reductions of up to 110kg on some models.

Space for occupants in rows two and three has been the company’s focus, with knee room of 217mm in row two & 108mm in row three.  The second row uses three independent seats with sliding bases and tilting backs.  Third-row passengers benefit from their own air vents.  Massaging front seats come as part of the Lounge Pack, along with the Relax feature which allows front seat passengers to stretch out their legs.

Loads of up to 2.75m in length can be carried with the front seats folded flat, and the company claims the Grand C4 has the widest boot in the category with 1.17m between the wheel arches.

A range of efficient engines will be available, and particularly noteworthy is the e-HDi 90 Airdream which boasts CO2 emissions of just 98 g/km and combined cycle fuel economy of 74.3 mpg.

A more powerful e-HDi 115 engine will also be available, with emissions of 104 g/km and 70.6 mpg economy on the combined cycle.

A new Euro 6-compliant BlueHDi engine will top the initial range, with CO2 emissions starting from 110 g/km.  Stop & Start technology is fitted to all diesel models as standard.

A new six-speed clutchless manual transmission, dubbed ETG6 (Efficient Tronic Gearbox) will be an option on the e-HDi 90 and 115 versions, and will provide both manual and automatic modes.

The styling of the new Grand C4 Picasso is said to have been influenced by Citroen’s recent concept cars, and features 3D-effect LED rear lights and new roof bars which seem to disappear into the car’s silhouette.

Inside, the dashboard features two displays – a 7-inch touchpad to control the car’s functions such as climate control, navigation, telephone, etc, plus a 12-inch panoramic HD screen which can be configured to display essential information such as a navigation display or active cruise control data.  The backdrop can be changed to a personal photo uploaded from a USB stick.

LED interior lighting is used heavily, with white illumination to the ceiling, storage areas, seat backs and door handles.

A panoramic windscreen is standard across the range, with a large glass roof available on the options list.

The Grand C4 Picasso now features radar-guided active cruise control, a system which also powers an anti-collision safety system.  An intelligent traction control system helps provide extra grip in slippery conditions.

Other gadgets include 360 Vision, which uses four cameras to give the driver a bird’s eye view, full rear view, or panoramic front view to aid in tricky manoeuvres, and Park Assist which automatically steers the car into tight spaces.

The new Citroen Grand C4 Picasso is expected to go on sale early next year.
