Built in Tuscaloosa / Alabama (USA), the GST is a derivative of the next Mercedes M-class. Both new vehicles are due in the U.S. in 2004 and will hit European and Asian shores in 2005. The additional GST-class brings production capacity from today’s 80.000 units per year to 200.000. While the new M-class will remain the luxury 4x4 off-roader with perfect on-road capabilities, the so-called Grand Sport Tourer will be a super-luxury and extremely huge Off-Roader / MPV crossover. Its dimensions are quite impressive: With a wheelbase of about 3.20 metres and an overall-length of 5.11 metres and a width 1.92 metres it will be very roomy and will have all comfort features conventional top-class limos generally offer their passengers. The great dimensions point to U.S. market. Height, however, will only be 1.65 metres
The new GST, as well as the next M-class, 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.
