The fourth generation of the A6 allroad quattro has been unveiled, 20 years after the model was first introduced in 1999.
The new Audi A6 allroad quattro is due to go on sale in the UK from August with an on the road price from around £55,000.
With its torque-rich TDI engine, standard quattro all-wheel drive, adaptive air suspension and increased ground clearance, the new A6 is also now even more adept at offering the best in executive class comfort thanks to its super-smooth mile hybrid drivetrains and exceptional new fully digital cabin based around the MMI touch response interface.
Town, country, river – extensive suspension features for on-road and off-road.
The A6 allroad quattro body is up to 45 millimetres higher than the A6 Avant. The ground clearance at standard ride height is 139mm, underscoring its off-road qualities. The A6 allroad quattro is equally powerful when used as a towing vehicle – it can tow up to 2.5 tons.
Adaptive air suspension with controlled damping is standard and was tuned specifically to boost the A6 allroad quattro’s off-road capabilities. It adjusts the ride height depending on the road speed and mode set in the Audi drive select system.
In auto and comfort modes, the A6 allroad quattro sets off at standard ride height with a ground clearance of 139 mm, which is then actively adjusted according to speed. If the highest ride height is selected at speeds of up to 22mph, the body is raised 45 mm. The body is lowered automatically when this speed is exceeded. At motorway speeds of above 74mph, the ride height is lowered by 15 mm.
If the A6 allroad quattro sets off in off-road mode, which covers speeds up to 49mph, the body is 30 mm higher than the normal ride height. Travelling at vey slow speeds below 22mph, lift mode adds another 15 mm, raising the ground clearance 45 mm above the normal position.
In addition to the specially adapted suspension, the A6 allroad quattro offers additional comfort features including standard hill descent control and tilt angle assist that allow it to take off-road terrain in its stride.
When negotiating light terrain, the driver can call up a display on the MMI monitor, which shows the current tilt angle in the longitudinal and transverse directions – where the vehicle is at risk of tipping over, a warning appears.
On a steep slope the hill descent control limits the speed in the range of 1.2 mph to 18.6 mph to a figure defined by the driver and brakes all four wheels selectively and individually as necessary.
On loose surfaces the system provides an additional braking wedge in front of the wheel by using a special ABS brake function.
In the Audi drive select offroad mode, all the relevant dynamic handling systems through to stabilisation control are tailored to off-road conditions.
Drive, suspension and equipment
High torque for high pulling power - in the UK the new A6 allroad quattro will initially be available with a choice of two V6 TDI engines. Both units generate their power from three litres of displacement and have been extensively modified in the transition to the new model.
Both also incorporate Audi's mild hybrid technology (MHEV), which makes driving even smoother and can reduce fuel consumption by up to 0.4 litres per 100 kilometres. It works on the basis of a new 48-volt main electrical system.
The belt alternator starter as the central MHEV component recovers up to 8 kW of power during braking and feeds the electricity into a separate lithium-ion battery with a capacity of 10 Ah. The new Audi A6 allroad quattro can coast with the engine switched off over wide speed ranges, and its start-stop mode kicks in early at 13mph.
The two TDI units transfer their power via an eight-speed tiptronic to the centre differential-based quattro all-wheel-drive system, which is also backed up by standard wheel-selective torque control. When driving at speed, this system brakes the two wheels with reduced load on the inside of a bend slightly before they can begin to spin. The drive torque is redirected to the wheels with better traction as a result.
The suspension of the A6 allroad quattro combines customary agility with very high levels of comfort. Apart from the adaptive air suspension with controlled damping it offers other highlights.
The new Audi A6 allroad quattro is:
4.95 metres long
1.90 metres wide
1.50 metres high
Digital native – infotainment, connectivity and driver assistance.
The A6 allroad quattro features the same extensive infotainment range found in its A6 and A7 sister models.
The all-digital operating system compromising a top large screen – measuring 10.1 inches in the top-of-the-line version – is used to control the infotainment. On the 8.6-inch display below, the driver operates the climate control, the comfort functions and the text input.
The natural-language voice control uses both onboard information as well as knowledge from the cloud to process all input. As an option the new A6 allroad quattro is also available with the cloud process all input. As an option the new A6 allroad quattro is also available with the Audi virtual cockpit (as part of the Technology Pack) – its 12.3-inch display is controlled with the multifunction buttons on the steering wheel, and it is complemented by the top-of-the-line MMI navigation plus infotainment control centre.
The navigation learns based on previous journeys and can provide the driver with suitable suggestions when choosing a route.
