Mercedes-Benz reveals first C-class details

Mercedes-Benz has revealed limited details about its new fourth-generation C-class sedan, more than two months before it is due to make its world debut at the Detroit auto show. Although the new BMW 3-series and Audi A4 rival is yet to official unveiled -- in fact, all we have so far are interior renderings -- Mercedes-Benz says the new C-class will be a significantly more advanced car than its predecessor in terms of construction, with a “best in class” weight figure and a level of structural integrity that it describes as being “unparalleled” in its class. Among its features is a new lightweight body structure that uses a newly developed aluminum hybrid construction process that Mercedes-Benz claims will shave as much as 220 pounds over the current model depending on the engine it uses.

Vauxhall Insignia facelift revealed for 2014

The Vauxhall Insignia gets a facelift for 2014 with new engines and lower prices The Vauxhall Insignia is a more than decent car – and a big improvement on the Vectra that went before – but it’s now almost five years old so it’s time for a bit of a facelift. Vauxhall has revealed the updated Insignia for 2014 that gets a decent raft of changes, both cosmetically and under the skin, to make it better to live with and more economical. Sensibly, Vauxhall has cut the bewildering range of Insignia trim levels from 14 to eight (do they need even that many?), with Design Trim at the bottom and Elite trim at the top, and the new Insignia Design starting at £16,279 – £3500 less than the old Insignia ES.
