Ford will add a third wind turbine at Dagenham to power the expansion of its diesel engine manufacturing site.

This extra turbine from Ecotricity enables Ford's Dagenham diesel centre to remain 100% wind powered following installation of a new 1.4/1.6-litre Duratorq TDCi engine line.

Ford offers 28 Fiesta, Fusion and Focus models powered by these diesel engines which will be London congestion charge exemption from October.

Transport for London's 100% congestion charge discount for cars emitting under 120g/km of CO2 are accelerating interest in low emission cars. Within two years all sub-130g/km CO2 cars will be free of vehicle excise duty (VED) for their first 12 months on the road.

As a result Ford Dagenham output is on track to top 1,000,000 engines this year to meet demand.
