With spring weather flourishing in Germany, Mercedes-Benz is stepping up activity at the Nürburgring. Among the sea of swirl-camouflaged prototypes comes something we haven't often seen. Rumors say C-Class and E-Class coupes and convertibles will be merged into a new CLE-Class, and this appears to be a hot AMG version, possibly called the CLE 63.
There's still much we don't know about this new model lineup. Considering the state of the prototype in these photos, it's possible Mercedes still doesn't know much either. Caught on public roads near an AMG test center at the Nürburgring, this prototype is far from production-ready. Janky exhaust tips poke from beneath the rear fascia from rectangular cut-outs that look like they were literally cut. Placeholder taillights are clearly visible, and a wire is hanging from beneath the trunk lid. Actually, looking closer, that could be a string used to open the trunk. Yeah, this is definitely an in-progress prototype.
