► New Audi A4 Allroad Quattro tested
► Features new all-wheel-drive system
► Telemetry reveals infrequent quattro use
After decades trumpeting the advantages of all-wheel drive, Audi is quietly revealing a downside: extra driven wheels cut mpg.
The solution is called ‘quattro with ultra’. Designed for Audis with longitudinal engines and dual-clutch or manual ’boxes, it activates all-wheel drive only when required. Audi tests showed the deficit to fwd economy dropped by almost 50%.
The new A4 Allroad Quattro debuts the tech with a 2.0-litre TFSI petrol, Audi no doubt eyeing the US market. All but the hottest 3.0-litre diesels (mit torque convertor) will graduate from quattro without ultra later in life.
It works by analysing sensors – steering, throttle, yaw etc – adapting to driver behaviour and, sometimes, reacting to surprise surface conditions. It’s impossible to detect the system engaging. Accelerate hard through a corner and you feel awd grippiness.
Drive sedately down a straight and you have no idea you’re two driveshafts short of the full Röhrl. Data analysis later proved we’d used quattro for only 20% of our test route. A diesel Allroad – old quattro, remember – felt similar, with only the chassis different: the petrol rolled more, its chassis perhaps tuned to US freeways.
And the rest? There’s a 34mm suspension hike, backpack-and-boots bodywork, and the same great interior, 505 litres of luggage space and power tailgate as the Avant, which for most of us does the job just fine. But there’s no denying the Allroad has a rugged appeal.
