After receiving 447 votes, the results are in and it looks like plug-in electric with petrol range extending - such as the E-Flex Chevy Volt was the clear favourite. Two other powertrain technologies fought it out for second place, Clean diesel and Diesel-electric hybrid. The rest of the field was further back.
Analysis: I'm doubtful diesel will have such a strong showing in two years. Perhaps what we need then is a plug-in electric with diesel range extending - a clean diesel take on the GM E-Flex platform if you will.
