The 508 composes itself with fluency and subtlety on undulating roads. Vertical body control over crests is tight, while the compression that follows is cushioned and progressive. The fact that the primary ride is so tidy, however, makes a sometimes questionable secondary ride that much more of a shame.
Our 19in-alloy-equipped 508 carried with it a tendency to emphasise the severity of ruts and bumps on more threadbare sections of road. Imperfections you sense may not have been quite so intrusive in rival D-segment saloons made their presence felt.
While not doing so in a bone-shattering fashion by any means, it was with enough sharpness to leave a cloud of doubt over the 508’s otherwise impressive manners.
Comfort mode helps to mute these disturbances to a degree, but not quite to the extent where you’re totally isolated from shudders and vibrations. The 508 seems happiest on comparatively smooth motorways, where those intrusions are at their most infrequent and you can make the most of its fluid primary ride.
At three full turns from lock to lock, the gearing of the 508’s steering rack errs on the slower side, and the diminutive wheel – now a signature trait of Peugeot interiors – does take some getting used to. Around town, there’s very little in the way of weight or feel here, although once you add pace it gains some reassuring heft if no additional propensity for communication.
