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 61 - 72 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.

Claimed economy for an average run is 68.9mpg so everyday Peugeot 508 RXH running costs should be affordable. Still, we would expect that to drop to around 60mpg if you are driving normally. Peugeot dealers are competitive, so servicing costs will not be as expensive as VW or Audi.

Peugeot 508 RXH emissions come out at 107g/km. This is largely down to its fuel-efficient engine, start/stop technology and, of course, the ZEV electric mode. Select this mode and you can run on pure electric for up to 2.5 miles and up to speeds of 40mph.

Peugeot 508 RXH reliability is unlikely to be an issue because the French car maker is improving with every model it produces. There have been few problems with the brand's most recent cars that include the RCZ and the 3008.

The 508 RXH has a solid feel to it and the plastics and interior trims look durable. The diesel engine is proven and should perform well.
