Mercedes-Benz is slowly but surely dropping bi-xenon headlights and the next model in line to receive the LED treatment is the SLK roadster. This near-production prototype wearing a thin layer of camouflage was spotted boasting the new headlight clusters which will obviously be in line with the latest products wearing the three-pointed star. These new headlights will incorporate LED daytime running lights so the SLK's DRLs mounted in the front bumper will be eliminated.

Moving at the back, it's easy to notice the taillights have different graphics with a thin white strip for the reverse lights whereas the outgoing SLK has a thicker strip positioned on the upper area of the cluster. Expect to see some minor revisions to both front and rear bumpers while the side profile will remain virtually the same. Some new body paints, fresh alloy wheel designs and a bunch of interior cabin tweaks are also on the agenda, but nothing to write home about.

A more significant novelty will be the addition of a warm SLC 450 AMG Sport model which will have a V6 3.0-liter twin-turbo pushing out 367 PS (270 kW) and 517 Nm (382 lb-ft) of torque sent to the road via a revised seven-speed automatic gearbox. Aside from the stronger heart, the new entry will also employ a more aggressive body, beefier brakes and larger alloy wheels to denote it’s the most powerful non-AMG version.

Word on the street says Mercedes-Benz will crack open the order books in December, so an official reveal should occur next month at the Frankfurt Motor Show. Anxious buyers will have to patiently wait until March next year to take delivery of the car.
