What is miles per pound?

Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 12 - 25 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

This is a supercar so insurance and fuel costs are fearsome but at least residual values are particularly strong so you’ll recoup a good proportion of its value when you come to sell.

911 is a polluting model. With an average of 295 g/km CO2 across the line-up, its emissions are high for a sports coupe. It’s worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is disappointingly thirsty, averaging 23 mpg.

The most impressive thing about the 911 is that it can take a thorough pasting day-after-day and still remain solid and start on the button.
