The fleet includes the Focus Electric and C-MAX Energi plug-in hybrid, beginning the second phase of the Ford-funded colognE-mobil research project.

Between now and 2015, the vehicles will be used to improve public perception and example possible improvements to infrastructure, including the use of renewable power and safety issues, as well as e-cabs, car sharing and ways of networking with public transport.

Bernhard Mattes, chairman Ford of Germany, commented: ‘The continuation of the colognE-mobile project underscores our clear commitment to environmentally responsible mobility, especially the electrification of vehicles.

‘We will gain a more complete picture in the second phase with more partners. This will help us to develop even more practical solutions that will further advance electric mobility.’

Launched in 2009, the colognE-mobil project now includes 11 partners including the University of Duisburg-Essen, city of Cologne, local cab company Taxiruf, Cologne/Bonn Airport, TÜV Rheinland, public transport providers KVB and RVK, Energiabau, Transportation Research & Consulting GmbH and DB Rent GmbH.
