It's been nearly four years since the Mercedes-Benz CL-Class underwent a major overhaul, so M-B is planning a few subtle improvements to the third-generation W216 model before an all-new S-Class coupe arrives on the scene in late 2014.
The new coupe will continue to be available in a variety of variants, but our spy shooters weathering the wintery climes have caught what they believe to be the 604-horsepower twin-turbocharged V12 version wearing a slightly modified fascia adorned with a single chrome slat, enlarged logo, LED daytime driving lamps and a new front bumper and splitter mildly reminiscent of the SLS AMG.
When the refreshed model debuts either next month at the Geneva Motor Show or later this year in Paris don't expect any seriously substantive tweaks to be made to the power train. That'll likely come in the next few years when Mercedes begins downsizing and turbo charging, and we expect the S-Class coupe to be one of the first models to benefit from the new mill.
