Body and exterior design
The new A6 allroad quattro is 4.94 meters long, 1.90 meters wide and 1.47m tall, making it a few millimeters bigger than the Avant. It follows the Audi ultra lightweight construction principle familiar from the sedan, with aluminum components making up roughly 20 percent of its body. Total vehicle weight has been reduced by as much as 70kg compared with the previous model.
The body of the new A6 allroad quattro sits six centimeters higher than that of the A6 Avant. Setting it apart are, in particular, the trim strips on the side sills, the more widely flared fenders and the single-frame grille with vertical slats. Stainless steel covers protect the underbody at the front and rear of the car, and the exhaust system ends in two large, flattened tailpipes. The roof rails are mounted on double bars.
The luggage compartment of the new A6 allroad quattro has a capacity of 565 liters. Latches in the luggage compartment make it easy to fold down the rear seats, increasing luggage capacity to 1680 liters. Standard equipment features underscore the practical character of the new model – a rail system with an included load-securing kit for dividing the luggage compartment as needed.
The new A6 allroad quattro is available with a choice of four V6 engines – one TFSI gasoline engine and three TDI units. All are three-liter engines with turbocharging and direct injection. Their fuel consumption has been reduced by as much as 20 percent compared with the previous model.
The 3.0 TFSI, which is boosted by a mechanically driven compressor, produces 228kW and 440Nm of torque. It accelerates the A6 allroad quattro from zero to 100 km/h in 5.9 seconds on the way to an electronically limited top speed of 250km/h. It consumes 8.9 liters of fuel per 100km.
The three variants of the 3.0 TDI produce 150kW, 180kW and 230kW; torque values are 450, 580 and 650Nm.
The most powerful TDI delivers its power to a smooth and fast-shifting eight-speed tiptronic transmission. The three other engines are paired with the seven-speed Stronic, a sporty dual-clutch transmission.
The quattro permanent four-wheel drive system is paired with torque vectoring. During dynamic driving this system brakes the wheels on the inside of the curve, which are under a reduced load, before they can slip. This further enhances traction and handling. The optional sport differential distributes the power in continuously variable proportions between the rear wheels.
The chassis of the A6 allroad quattro combines sportiness with comfort. The new electromechanical power steering is sensitive and highly efficient. The optional dynamic steering adjusts the steering ratio to the speed driven.
With the Audi drive select system, the driver can vary the function of the steering, the air suspension, the throttle pedal, the automatic transmission, the sport differential, the automatic air conditioning, the lighting and the adaptive cruise control. In Efficiency mode, these systems work as economically as possible; their function can be very freely configured in Individual mode.
The adaptive air suspension, which combines air suspension with controlled damping, comes as standard. It lowers the body by 15mm at high speed and raises it by 35mm at the push of a button. This allroad mode is suitable for rough terrain. Furthermore, the driver can select a lift mode at low speeds. An additional 10mm enables the new AudiA6allroadquattro to also handle major irregularities in the road surface.
