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 16 - 29 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.

You can get a good deal on a used Grand Cherokee, but it will never be a cheap car to run. All the engines are thirsty with even the most economical CRD model only returning 29mpg. Jeep servicing isn’t especially cheap either so it’s worth looking for an independent Jeep or 4x4 specialist who will charge less.

The Grand Cherokee performs disappointingly on the eco front. The petrol engines are particularly inefficient, while the 2.7 CRD (the cleanest engine in the range) still emits 255g/km of CO2 and averages a just 29mpg.

Jeep models tend to be mechanically robust and although the interiors don’t suffer abuse too well, we’ve heard of few problems with the Grand Cherokee.
