THE PROJECT

• Developed by DaimlerChrysler do Brazil.

• Reduction of development and production costs.

• “Clinics” with clients and bodybuilders (presentation of the project concept to

customers and bodybuilders to obtain their inputs).

• 15 durability test vehicles:

- 715 C → 9 vehicles; running distance: 850.000 km;

- 915 C → 6 vehicles; running distance: 350.000 km.

• Reliability tests - 40 units in operation at

customers and 8 vehicles simulating

client applications.

• The Light truck market has been increasing during the last couple of years.

• DC is seeking for sales leadership.

• Even though Mercedes-Benz is very well known in the segment,

competition is present.

• “Boom” in the merchandise distribution and intensification of

logistic intelligence (pressure for reduction of transport costs).

• New market demands: e.g.: agile trucks, comfortable vehicles

and easy handling: truck driver is a sales man.
