When we first drove the new A4 saloon, it was clear that not only had the outer skin changed dramatically (the roof is the only panel carried over from the old car), but a good degree of everything beneath had been worked on, too. And while the melee of new lines, shapes and angles only looks strong when viewed from head-on, the engineering changes – designed to make the A4 a more enjoyable drive – are a lot more successful.
In practical estate terms, the A4 remains unchanged from the old car, which means a reasonably capacious but hardly cavernous boot. The new Avant is actually 41mm longer overall (although that is all crash structure). With the rear seats folded flat you’ll still get the same 1184 litres of load space which, while useful, is a long way short of the 1850 litres you get with a Vauxhall Vectra estate; the Avant is more about style than load-lugging.
Dynamics have not recently been an Audi strong point, and the parts bin has been raided in a quest to tighten up the A4: there’s the S4’s Servotronic steering and its influence in the redesigned four-link front suspension, plus new A6-style rear dampers. The mounting bushes and geometry have also been tweaked and there are new, larger brake discs, a better ESP system and bodyshell reinforcement.The new range costs between £19,915 and £27,820 and comprises the established petrol 1.6, 2.0 and 1.8T engines boosted by some new high-tech firepower: FSI-equipped 2.0-litre turbo and 3.2 V6 engines. The proven 1.9, 2,0 and 2.5 V6 turbodiesels are joined by a new 3.0-litre V6 TDi.
The latter is the engine tested here. Having already received praise in the new A6 (it’s detuned slightly from that application), the 2967cc DOHC 24-valve motor is the latest in diesel technology. With common-rail injection using piezo injectors (which give extra-fine control over the fuel spray in the combustion chamber) and a variable-vane, twin-intercooler turbo, it produces 201bhp and a solid 332lb ft from 1400-3150rpm – yet it’s Euro4 emissions-compliant (meaning less tax for company car users). The only gearbox currently available is a new-to-the-A4 six-speed Tiptronic (an automatic with manual override; a proper manual will follow) and permanent four-wheel drive is the only drivetrain option, with a Torsen differential splitting the power 50:50 front and rear in typical driving conditions.
