The rumormongers over at Auto Motor Und Sport report that during a conversation with Hans Dieter Multhaupt, Daimler Chrysler's Vice President of Program Management and Development, the idea of a convertible CL was hinted at, along with the possibility of a diesel mill finding its way under the hood.
The translated article quotes Mr. Multhaupt, as saying that the engineers and designers take steps to insure that these variants will be possible with limited modifications. The one factor that leads to broader offerings is consumer demand, which Mercedes hasn't seen, yet.
We're not sure about the diesel, but it's probably a no-brainer that a droptop version of the S-Class based coupe will make it to production. Soon.
