7. MPG: Better than advertised
Anecdotally you may have heard about the amazing fuel economy diesel engines deliver and there’s good reason for it. More than just a random hypermiler, those who purchase diesel-powered cars generally exceed the advertised fuel economy – and by a significant margin.
Taking a look at fueleconomy.gov, owners of diesel vehicles are likely to meet or exceed the EPA estimates of their vehicles. The Jetta TDI is rated to get 34 mpg combined, but consumer data points to drivers getting an average of 44 mpg instead.
