The new M-class and GST will both have unibody construction and no ladder frame. Computer-controlled air-suspension will be standard for the GST while it will be an option for the new M-class. The new SL's sophisticated brake-by-wire system, though, will be on board of both cars. While the new M-class will be a five-seater, the GST will feature three rows of seats.
GDI V6-engines with 3.0 or 3.6 litres (231 / 258 HP) as well as Common-Rail diesel V6s with 2.6 or 3.0 litres (190 / 218 HP) will be available from the start. A 5-litre V8 with 300 HP will be offered for both cars later, as well as a 5.5-litre V8 with 350 HP for the AMG-version.
