From the development of a concept through to it becoming a reality, the Mercedes-Benz team looks at many different areas to make sure the vehicles are the safest on the road.

Mercedes-Benz has been testing the new B-Class F-Cell in Sweden, a project that involves many different parties, not just engineers.

"Apart from research and development, all the relevant departments for product development have been in on the project from the very beginning. That includes sales, purchasing, quality management, and even aftersales and customer care," said Anton Sonntag, project manager.

Running on electric motors, the F-Cell is pioneering the most innovative drive technologies and offers power of 320Nm.

As the test drivers run through the new technologies, the data is fed into a black box and back to analysts in a studio.

"It’s a bit like the technology used in Formula One racing," said Jurgen Friedrich, the man in charge of operation and service for the F-Cell test fleet.

"Everyone involved in this development project is thrilled with the driving performance of the cars and the robustness of the technology. With the B-Class F-Cell, we’ve taken another major step toward the series production of a fuel cell car," Mr Sonntag said.
