The 508 is available with four diesel engines. There’s a 110bhp 1.6-litre that’s up to the job, but the 138bhp 2.0-litre is usefully stronger. In fact, it’s so good that there’s no point in upgrading to the 161bhp 2.0-litre or the 201bhp 2.2. The two petrol options – a 118bhp 1.6 and a 154bhp 1.6 turbo – make no sense.
Peugeot 508 Saloon ride & handling
The 508’s suspension keeps body movements well controlled, while the steering is responsive, if not exactly full of feel. GT versions are sharper still, thanks to a more sophisticated front suspension setup. Unfortunately, the ride is firm and unsettled at all speeds, whichever 508 you choose.
Peugeot 508 Saloon refinement
All of the engines we’ve driven so far have been smooth when worked and unobtrusive at speed, and road noise isn’t a problem either. Unfortunately, you can hear the suspension working on poor roads, and there’s a fair bit of wind noise on the motorway.
