IT’S revamp time for the W205 Mercedes-Benz C-Class, which will receive a number of updates inspired both by its bigger siblings.

Wheels’ spy photographers captured the facelifted sedan testing in Europe, ahead of a release on that continent later this year before an expected early-2018 arrival here.

With minimal disguise, it’s easy to spot a new headlight set-up inspired by the single round LED projector lamp of the E-Class. The LED tail-lights indicate there will be a switch from a dual-C-shape design to single C shape.

Other exterior revisions will include new treatments for the front and rear bumpers.

Sales of the C-Class sedan and wagon slipped 27 per cent in 2016, yet the Mercedes pair still out-sold every medium car in Australia except for the Toyota Camry.
