By activating the parking pilot and garage pilot, which will be introduced in stages from 2018, the driver can manoeuvre the A7 Sportback autonomously into and out of a parking space or garage without having to sit in the car. This is performed by launching the function via the myAudi app on their smartphone. These functions are just two of a total of 39 driver assistance systems the A7 Sportback will offer to make daily use easier for the driver. They are split into three packages: Parking (gradual introduction beginning in 2018), City Assist (with the new Cross Traffic Assist Front feature) and Tour. The latter includes features such as the efficiency assistant, which facilitates a driving style conducive to reducing consumption, and the adaptive driving assistant (ADA), which supplements the adaptive cruise assist with helpful steering interventions designed to keep the car in its marked lane. All driver assistance systems feature improved control mechanisms.
Intelligent and convenient: the driver assistance systems
In the UK the new A7 Sportback is initially based around two specification levels – Sport and S line – and two engines classified according to the new Audi naming convention first introduced in the new A8 luxury saloon. The 55 TFSI is powered by a petrol V6 TFSI offering 340PS and 500Nm. From rest, 62mph is reached in 5.3 seconds and its top speed is 155mph. In terms of efficiency, up to 40.4mpg combined is possible, with a CO2 low of 158g/km. A 50 TDI variant is also available, utilising a V6 TDI diesel that delivers 286PS and 620Nm of torque. It enables the A7 Sportback to reach 62mph in 5.7 seconds and a 155mph top speed. Combined fuel consumption peaks at 50.4mpg, corresponding to 147g/km of CO2. Specification will be appropriately high, with LED front and rear lights and 19-inch alloy wheels maximising presence externally in Sport versions, and Twin leather- upholstered seats with full electric adjustment upfront and LED ambient interior lighting setting the scene inside. Technology features common to both levels will include the fully digital Audi Virtual Cockpit, MMI Navigation Plus with MMI Touch, the Audi Smartphone Interface and the Audi Phone Box with wireless charging for QI-enabled compatible phones. The list of electronic driver assistants will also feature the Audi Parking System Plus with rear-view camera, the Audi Pre-sense Front collision warning and automatic braking system and the Lane Departure Warning system. S line specification ramps up the visual appeal even further with 20-inch alloy wheels, HD Matrix LED headlights with dynamic front and rear indicators and coming/leaving home animations, sport suspension lowering the body by ten millimetres, and S line-specific body styling. It also lends the cabin a more dynamic air through generously bolstered front sport seats upholstered in leather and Alcantara and S line-specific interior detailing. Another core component of the standard technology package benefiting all A7 Sportback models is the new mild hybrid drivetrain (MHEV) made possible by the newly introduced 48-volt primary electrical system. At speeds of between 34 and 99mph, it enables the V6 engines to be deactivated and the A7 Sportback to coast in freewheeling mode. The Belt Alternator Starter (BAS) re-fires the engine smoothly and comfortably after coasting, and is capable of channelling up to 12kW of energy back into the lithium ion battery during recuperative braking. The start-stop function has also been significantly expanded and now activates at 13mph. In combination with the standard front camera, the engine is restarted predictively while at a standstill as soon as the vehicle ahead begins to move. In real-world driving, the MHEV technology reduces fuel consumption by up to 0.7 litres per 100 kilometres.
Appropriately high UK specification
The two engines work with a seven-speed S tronic twin-clutch transmission (55 TFSI) and an eight-speed tiptronic (50 TDI), and their outputs are proficiently managed by the latest iterations of the quattro drivetrain. For the TFSI engine, the efficient quattro with ultra technology will channel drive to the rear wheels in a split-second when necessary. The drivetrain with its equally weighted comfort, efficiency and performance focus is complemented by a platform developed according to the same philosophy. The new electronic chassis program (ECP) – the central controller for the chassis – and the four suspension options including updated adaptive air suspension make the car feel supple and luxurious during cruising without curbing its ability to iron out more challenging roads. Many aspects of the core suspension concept have been newly developed. Sport models feature an absorbent yet tightly controlled conventionally sprung set-up, while S line versions feature the sport suspension that lowers ride height by 10 millimetres. Steel-sprung suspension with electronically controlled damping and the self-levelling adaptive air suspension are available as options for both variants. Progressive steering with a ratio that becomes more direct as lock is applied is standard, and has been reworked with a focus on providing more detailed road surface feedback. For optimal ability through the switchbacks and increased lower-speed manoevrability dynamic all-wheel-steering is also available from the options list, as is the quattro sport differential which actively distributes drive torque between the rear wheels for maximum cornering adjustability. The various options are all integrated into the control function of the electronic chassis platform (ECP). These systems are closely networked for maximum precision. The driver can use the Audi drive select system to activate different drive profiles in which the differentiation between comfort and dynamic options is more pronounced than in the previous model.
