The new generation of Opel Meriva which will make debut at the next Geneva Autoshow is already one of the best new cars of 2010, because it comes with so many new and exciting features inside and out. We had a gallery of the car’s exterior design before and now Opel reveals its stunning interior as well. The new Meriva is all about Flexing! And if you wonder what’s that, hit the jump to learn more…

As you see in the picture above, the Meriva’s cabin is based on the same design as the Insignia and Astra but thanks a full length panoramic roof and large windows, it feels much roomier and the brightness and visibility are also incredible! And as for the Flex features, it comes with unique-in-class FlexDoors, FlexRails and FlexSpace.

FlexRails explained: The Meriva’s unique FlexRail system provides convenient and adaptable storage for a wide range of everyday items, from handbags and colouring books to iPods and sunglasses.

Space for the FlexRail between the front seats has been liberated by raising the gearshift location and replacing the traditional handbrake with an easy to use electric park brake button (standard on all models). The result is an uninterrupted storage zone that extends rearward from the base of the centre stack and is accessible from the rear seats.

FlexRail’s floor module comprises two cup holders, Aux-in/USB connections and a 12-volt socket. Above this area, on certain models, twin polished aluminium rails feature, and on the range-topping SE a flip-top armrest module is attached, with a smaller storage/cup holder tray sitting below it. Both can be shifted into a variety of fixed positions along the rails, while rear seat passengers benefit from the option of a rear armrest module, which can be fitted to the centre seat back section when it’s folded down between them.

FlexSpace explained: The new Meriva’s innovative FlexSpace system offers a range of cabin configurations without having to remove any seats, and is now improved with a one-step action when sliding the rear seat cushions or when lowering the rear seatbacks.

While FlexSpace makes it easy for owners to convert the Meriva from five seats to two, both its outer rear seats can be moved fore and aft individually, and also slide inwards to provide more shoulder width and leg room in a spacious four-seat layout. Additionally, rear seat backs can be fully lowered without having to remove their head restraints.

Rear seatbacks up, the Meriva’s boot has a 400-litre capacity, increasing to 920-litres with the seatbacks folded. But use all the space up to the roof and an impressive 1500-litres capacity is available.
