A REVAMPED Mercedes-Benz C-Class is on the way and will be on the road in the autumn.

With slight design changes including a diamond-effect front grille on AMG Line models and reworked bumpers, the updated line up is due for release in August in both saloon and estate styles.

Interior upgrades see a cleaner look to the cockpit with a new open-pore wood trim available.

LED headlights will be standard on UK models while ultra-bright Multibeam lamps are now an option.

New colours - a metallic silver and emerald green finish - are being added to the range as is the option of pneumatic seats with massaging functions and adjustable bolster support.

The new C-Class also adopts the display concept of the current S-Class, with an optional fully digital instrument display offering the three different display styles.

The basic model features a classic two-tube instrument cluster with a central 5.5-inch colour display.

The fully digital instrument display is an option and comes with a 12.3-inch display which can be switched through the three modes at the touch of a button. Sat nav and eco mode information is now included in the read out.

The multimedia screen above the centre console is also available in two sizes, seven or 10.25 inches.

On the driving front, more safety features are fitted allowing the new C-Class to be operated semi-autonomously in certain conditions.

The new C-Class also comes with extended automatic emergency braking as standard and an improved lane changing function as well as predictive speed control using data from the sat nav.

The current C-Class, launched four years ago, and priced from £29,035, has become Mercedes' best seller, notching up more than 400,000 sales globally last year.

Prices and precise UK specification for the new model are due to be announced in March.
