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 17 - 19 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.

The Quattroporte should retain 73 per cent of its new cost after six months, putting it on a par with the class leader in residual values, the Mercedes-Benz S500. However, the Quattroporte is not cheap to buy or to run. Insurance is group 20, fuel economy is 19mpg at best (18mpg with the more powerful engines) and sky high emissions mean it falls into the highest road tax bracket.

But perhaps the biggest cost is Maserati dealer servicing.

The Quattroporte scores miserably on the eco front, with an average of 353g/km CO2 across the model line-up. It’s very thirsty too – the 4.7-litre engine returns just 18mpg.

Thee are no reports of problems with this range and all Quattroporte models come with a three year, unlimited mileage warranty and a servicing package extending to three years or 30,000 miles.
