June 4, 2006 In the race to provide more fuel-efficient, emmission-friendly automotive technologies, diesel-electric hybrids are showing some very promising form. Ricardo, QinetiQ and PSA Peugeot Citroen have announced the results of their Efficient-C collaborative research project which has successfully met the UK Department for Transport’s Ultra Low Carbon Car Challenge. The two year Efficient-C programme has culminated in the delivery of a full-hybrid diesel demonstrator vehicle emitting just 99 g/km CO2 (equivalent to 3.75 litres per 100km or over 75mpg) based on a fully featured Citroen Berlingo Multispace family car. This is a significant leap forward of 30 per cent improvement in fuel economy and CO2 emissions when compared to the equivalent diesel production vehicle. Furthermore the same diesel hybrid powertrain fitted in a C-segment 5 door saloon would only emit 90g tank-to-wheel CO2.
