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 44 - 74 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 most frugal engine on the 508 SW line-up is the 1.6 l e-HDi 112bhp engine mated to the six-speed EGC manual gearbox. The manufacturer claims that the 508 SW will average 64.2mpg. Servicing costs are usually on a par with Ford and Vauxhall and less expensive than the German brands.

Fleet manager’s car of choice will be the 1.6 l e-HDi 112 engine mated to the six-speed EGC manual gearbox. It emits 109g/km of CO2.

The Peugeot record on this front is improving. There have been few problems with the brand’s most recent cars which included the RCZ and the 3008. The 508 has a solid feel to it and the plastics and interior trims are a massive improvement. The engines are proven and should perform well.
