Unlike the E-class, there is no six-cylinder CLS, only the V-8 CLS550 and the rocket-like CLS63 AMG. Too much power isn?t really a problem (is it ever?), but the CLS?like the E-class V-8s?comes standard with Mercedes? Airmatic semi-active air suspension with adaptive damping system. Although its adaptive damping feature promises the best of both worlds?a smooth ride and firm cornering?in practice, the air suspension is stiff and jiggly, with frequent side-to-side rocking motions. The driver can select among three different damper settings, and strangely the car actually rides a bit better in the firmest setting, as the rocking motions are lessened (but not eliminated), at a cost of somewhat greater impact harshness. The disappointment here isn?t that the ride is horribly stiff, it?s that the design sets you up to expect one thing, and the chassis dynamics deliver another. Sorry, but after I flicked up the elegant little door (with its cool, frameless glass) and settled in facing the artfully curved dashboard, I was expecting to glide on down the road with the fluidity of a Jaguar XF?or at least a steel-sprung E-class.
