New-look Mercedes-Benz E-Class spied

Mercedes-Benz has again been caught testing updates to its E-Class range.

The brand hopes that changes to its mainstay will take market share from its premium competitors Audi, BMW, Lexus and Jaguar.

Spies suggest the revised E-Class will drop its four-headlight look in favour of a sleek new snout to bring it in line with other models.

The updated Mercedes-Benz E-Class is expected to go on sale in a year.

Sales of the E-Class coupe and convertible last month were down 40 per cent on October last year. Sales are down 26.5 per cent for the year to date.

By comparison, the refreshed Mercedes-Benz SLK convertible coupe is on track for a year-to-year sales increase of 150 per cent.

But the E-Class coupe and convertible has outsold its main competitor, the Audi A5, in the year to date, although Audi has been closing the gap.

BMW's 5-Series leads the Mercedes E-Class, Audi A6 and Lexus GS in sedan sales for 2012.
