"Weighted" mpg figures Explanation
Plug-in hybrid fuel economy explained
Official fuel economy tests give a so-called "weighted" mpg for plugin hybrids (PHEVs). This attempts to account for the fact they can be driven either under petrol/diesel power, or under electric power.
The current test and calculation is far from perfect however, giving eyebrow-raising figures as high as 250mpg. Such high figures will not be even remotely achievable for owners who regularly rely on their PHEV's petrol or diesel engine.
For now, Parkers advice is to use weighted mpg only to compare the relative economy of PHEVs rather than to compare a PHEV with a petrol or diesel car. Thinking of weighted mpg as mpg in the conventional sense is unlikely to be informative.Close
