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 23 - 36 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.

Fuel economy is a concern on the petrol engines. Although the 5.7-litre HEMI uses a system that shuts down part of the engine when it’s cruising on the motorway, it still only returns 23mpg on the combined cycle and it’s worse when you’re pushing. The 3.5 V6 is little better with 25mpg. Insurance groups are reasonable for a car of this size and pace, ranging from 16 for the CRD to 18 for the V8 HEMI.

The 300C performs badly on the eco front and even the most efficient engine – the CRD – emits 215g/km of CO2 and is capable of 35mpg. That’s poor compared to rivals from BMW and Audi.

The good news is that the 300C is built in Austria, where quality standards are stricter than in America. It seems to have worked, as 300C feels well put together and we’ve not heard any reports of problems.
