How do you compare the fuel economies and efficiencies of electric versus petrol/diesel cars?
With the coming of electric vehicles, wouldn’t it be better to start referring to all vehicles economy as MP£ or Miles per Euro as standard rather than mpg? As an example, my Skoda Fabia Estate diesel tells me it is showing 63mpg. How do the electric v carbon fuels compare, price-wise?

The issue with your idea is it's very dependent on the cost of fuel. Just like with petrol, the cost of electricity varies a lot – anything from around 13p per kWh (at home) to 69p per kWh (at the most convenient motorway rapid chargers). There are ways of comparing the efficiency of electric vehicles – many manufacturers quote the distance an electric car can cover per kWh of electricity, which is probably the closest alternative to MPG. Another popular metric is kWh/100 miles – essentially, how much electricity is required for an electric car to cover 100 miles.
