The official figures don’t tell the whole story here. As with other plug-ins, you’ll need to make good use of the plug itself to get close to the 508 SW Hybrid's official fuel-economy figures, using the car’s quoted 33-39 miles of electric range as often as possible to offset the times that the engine is moving it instead. A charge takes a couple of hours, which should be possible at home, at work or during shopping trips, so it’s not a deal-breaker.

You may also want to learn the different driving modes – Sport, Normal and Eco, plus the option to hold charge for later in a journey – to maximise its potential. Of course, if you leave the car in Normal or Eco, it’ll do a pretty good job of blending power sources itself, and many drivers prefer to let the car do its own thing. The select few who prioritise Sport will have the most fun, with engine and motor offering the greatest assistance here.

Peugeot 508 SW Hybrid MPG & CO2 emissions

Officially Peugeot quotes a high fuel-economy figure of 235mpg and a low of 166mpg, neither of which sound too bad but do rely on a significant use of the car’s electric component. You’ll be doing well to get near the official maximum electric range of 39 miles, but the usable range should still cover many commutes.
