MERCEDES says its new C-Class will have shed a lot of weight by the time it goes on sale next year.
And the makers underlined this with details of the new lightweight body structure.
It derives, in part, from a newly-developed aluminum hybrid construction process.
Mercedes says that will slice off up to 100kg. And it could mean a 20pc reduction in fuel consumption without any loss in power.
The new saloon will make its world debut at the Detroit auto show in January.
Some versions of the C-Class will have an optional Airmatic air suspension.
This allows you to choose between Comfort, ECO, Sport and Sport Plus modes depending on how firm you want the suspension.
Inside will be focused on a free-standing, central 7ins colour monitor display and equipment will include a fingertip-controlled touch pad in the centre console and a free-standing central display.
A couple of smart elements include an air con system that uses GPS data to close the air recirculation flap in tunnels to keep out fume-filled air from entering the cabin and a front passenger seat that uses a sensor to detect the use of any child seat and automatically disengage the front passenger airbag.
