Ford's eWheelDrive has designs on the urban car of the future

It's predicted that by the year 2050 there will be 9.3 billion people on Earth and 6.4 billion of them will be living in cities. There could also be four times as many cars on the roads as today, leading to an incredible degree of urban congestion and gridlock. That’s the impetus behind Ford and technology partner Schaeffler’s eWheelDrive electric research car, that moves the motor to the wheel hubs.
Demonstrated last Friday at Lommel, Belgium, the eWheelDrive is under development by Ford and project leader Schaeffler, a German automotive component manufacturer and supplier. The aim of the project is to investigate the potential for smaller, more agile cars better suited to crowded urban environments.
The eWheelDrive doesn't look very revolutionary. It’s based on that most conventional of cars, the Ford Fiesta, but the real secret isn’t under the bonnet because there’s nothing there except the battery. Instead, the engine has given way to two electric motors mounted in the hubs of the rear wheels along with the braking and cooling systems.
This setup also isn’t entirely new, but what is new is the fact that the eWheelDrive is not intended to make it more sporty or just greener, but as a way of developing car technologies for increasingly crowded city streets. The design frees up space under the bonnet that is normally occupied by a conventional engine or a central electric motor, opening the door for smaller, more agile cars that are more able to negotiate the warrens of London or Hong Kong.
According to the partners, such an arrangement would allow automakers to build a four-person car in the space of two-person car or to produce new steering arrangements that could allow cars to drive sideways to maneuver into the tightest of parking spaces. “This highly integrated wheel-hub drive makes it possible to rethink the city car without restrictions, and could be a key factor in new vehicle concepts and automobile platforms in the future,” said Peter Gutzmer, chief technical officer, Schaeffler.
The next step for Ford and Schaeffler will be to team up with Continental, RWTH Aachen and the University of Applied Sciences, Regensburg, on project MEHREN (Multimotor Electric Vehicle with Highest Room and Energy Efficiency) to develop two new vehicles by 2015.
The aim of the project will be to increase the integration of in-wheel motors in a car, as well as studying vehicle dynamics control, braking, stability and the ”fun-to-drive” factor. The goal of will be to solve problems caused by heavier wheels, improve brakes, reduce noise and vibration, improve the suspension, and ensure that the motors deliver enough torque.
“This is an exciting project to work on with Schaeffler because it potentially opens new options for the development of zero emission vehicles with very efficient packaging and exceptional maneuverability,” said Pim van der Jagt, Ford’s director of Research and Advanced Engineering in Europe. “Looking forward, we have the opportunity to scope out the vehicle’s capabilities and how we might overcome some of the challenges presented by implementing the technology.”
