The A4 has plainly been designed and engineered for high-mileage business users with a healthy disdain for compromise – those who want a car that’s as quick to get to outside lane speeds as anything else for the money but is also quiet, smooth, easy to operate and economical with it.
At least in some ways, they’ll find what they’re looking for here. All A4s get intelligent switchable engine mounts and an acoustic noise-filtering windscreen as standard, and our test example added acoustic glazing for its side and rear windows, too.
It was pleasantly mechanically refined, suppressing engine noise very well and ending up a noticeable 2dB quieter than an equivalent Mercedes-Benz C-Class at both idle and at maximum revs in third gear.
However, cruising at 30mph and 50mph, the Mercedes registered less noise, a difference attributable to the gently rumbling distant coarseness of the Audi’s low-profile Hankook tyres, S line 19in alloy wheels and passive sports suspension. On smaller rims and differently tuned chassis settings, the A4 may well deliver the cruising manners many owners will expect, but it evidently won’t do so unconditionally.
