  • 1. MPG - miles per gallon - SMMT is the Society of Motor Manufacturers and Traders that represents the UK auto industry (http://www.smmt.co.uk/)

    2. Applied mpg - adjusted downwards by 13 percent(petrol) and 9% (diesel cars) to take account of real driving conditions and lower fuel economy for older cars.A57

    3. For LPG, mpg is assumed to be 20 percent lower than for petrol due to lower volumetric energy density.
