Remember all those back and forths in the fight between Porsche and the city of London over laws regarding dirty vehicles in the city? Turns out Porsche might have been on to something with their poll that found 75 percent of Londoners thought the £25 congestion charge was too high. Maybe.

Research conducted by New Car Net (through its website, with over 1,400 participants) found that motorists in Londoners were among the least likely in the UK to think about buying a vehicle that wasn't powered by something other than diesel or petrol. New Car Net asked potential car buyers this question: "When you buy a new car, would you consider an alternative fuel (ie. other than regular petrol or diesel)?" and found Londoners answered yes 65.5 percent of the time. While that's well over half, only one section of the country (NE England) had a lower response rate. While there are a lot of people who said they'd consider an alternative, only one in 140 actually bought such a vehicle (for example, a hybrid, or a biofuel- or LPG-powered vehicle) in the UK last year, New Car Net discovered. Let's remember that there simply aren't that many vehicles powered by say, batteries or - ha! - hydrogen fuel cells available these days. More details after the jump.
