New Audi A6 has mild hybrid tech across the range

The new Audi A6 Saloon will become available in the UK this summer. The main features include an all-digital control system, comprehensive connectivity and mild hybrid technology. The new model incorporates many of the refinements and innovations from the company’s latest A8 luxury flagship.

Audi says the new MMI touch response system sets new standards in terms of intuitive operation and personalisation. The all-digital operating system with its touchscreen format provides haptic and acoustic response to inputs and offers fast access to vehicle functions thanks to its logical and flat menu structure. Its configurable favourites buttons help tailor the system to the user’s preferences, and it allows up to seven drivers to store their preferred settings in individual user profiles and set up to 400 parameters. Central vehicle functions can be placed in the required position in the MMI screen using drag-and-drop – similar to the user experience with smartphone apps.

It processes questions and commands in two ways, with onboard stored data and also – in conjunction with MMI navigation plus – with detailed knowledge from the cloud.

The driver controls the infotainment via the upper display, which measures 8.8-inches in standard form or 10.1 inches where the optional MMI navigation plus upgrade has been specified. The lower 8.6-inch display, located in the console in the centre tunnel, is used for the climate control and for the convenience functions and text input. The fully digital Audi Virtual Cockpit with its 12.3-inch high resolution in-binnacle LCD screen is optionally available, as is a full colour head-up display.

The optional MMI navigation plus – a media hub with a new design and high speed data transfer according to the LTE Advanced standard – also offers a host of new navigation features. These include a self-learning function based on the driven routes, which generates intelligent search suggestions. Route guidance is provided online on the servers run by service provider HERE; these servers factor in the traffic situation in the entire region. If the flow of data is interrupted, the navigation switches to the online route guidance that runs in parallel. Updates are available as standard for the navigation map for three years.

MMI navigation plus also offers optional add-on modules, including two sound systems headed by the Bang & Olufsen Advanced Sound System delivering 3D sound.

Audi connect online services also provide the car-to-X services traffic sign and hazard information. They use the swarm intelligence from the Audi fleet and network the Audi A6 with its environment. Shortly after launch, the on-street parking service will be added, which makes looking for a parking space easier. Using the myAudi app, owners of the new A6 can access the brand’s digital services via a smartphone.

As an option, the Audi connect key replaces the conventional vehicle key. It allows an Android smartphone to lock and unlock the car and start the engine. Near Field Communication transfers data to the car. The owner can pass the access data onto five people or smartphones.

Driver assistance systems include the parking pilot and the garage pilot, which will become available at a later date and will be capable of autonomously manoeuvring the car into and out of a parking space or garage. The driver can get out of the car before activating and monitoring the process using the myAudi app on their smartphone. To do so, the driver must continuously hold down the relevant function key.

The parking pilot and the garage pilot will form part of the forthcoming Parking pack. Two other packages will be available at launch – the City assist package includes features such as the new crossing assist system, while the Tour package offers adaptive cruise assist, which supplements the adaptive cruise control by means of gentle steering intervention to keep the vehicle in lane, and the efficiency assist, which promotes an economical driving style.

Behind the extensive assistance systems lies a high-tech module: the central driver assistance controller (zFAS). It continuously calculates a detailed model of the environment from a fusion of sensor data. Depending on equipment, the sensor set includes up to five radar sensors, five cameras, twelve ultrasonic sensors as well as a laser scanner – another major innovation.

All engines in the new A6 feature new mild-hybrid technology. Here a belt alternator starter (BAS) works together with a lithium-ion battery, enabling the A6 to coast at speeds of between 34mph and 99mph in the interest of fuel economy and to initiate its start-stop function earlier – at speeds of 13mph and below. The engine is restarted from standstill predictively as soon as the vehicle in front of the Audi A6 starts moving. During deceleration, the BAS recovers up to 12 kW of energy. In real-world driving, the MHEV technology reduces fuel consumption by up to 0.7 litres per 100 kilometres (62 miles).

The interior of the new Audi A6 is larger than in the outgoing model. Legroom, headroom and shoulder room measurements in both front and rear are more generous than previously.

Audi says the new Audi A6 is noticeably sharper than the outgoing model from a handling perspective as well. Customers can choose from four set-ups: the conventional steel spring suspension, the sport suspension, the suspension with damper control and the adaptive air suspension, also with controlled damping.

Progressive steering which becomes quicker and more direct as the steering angle increases is standard, and dynamic all-wheel steering can also be added to further enhance this agility. It can vary the steering ratio between 9.5:1 and 16.5:1 as a function of speed with the help of strain wave gearing at the front and a spindle on the rear axle that turns the rear wheels by as much as 5 degrees. At low speed, the wheels steer in the opposite direction to the front wheels, reducing the turning circle by up to 1.1 metres to 11.1 metres, while at higher speeds the wheels turn in the same direction to optimise stability when travelling in a straight line or changing lanes.

As part of the launch in the European markets, Audi offers the new A6 with two engines – one TFSI and one TDI. The petrol unit (combined fuel economy: 39.7mpg – 42.1mpg, CO2 emissions 161 g/km – 151 g/km) is a 3.0 TFSI. The V6 turbocharged engine powers the saloon from rest to 62mph in 5.1 seconds using its 335 bhp and 368.8 lb-ft resource, and tops out at an electronically limited 155mph. The 3.0 TDI with 282 bhp delivers similar performance (combined fuel economy 48.7mpg – 51.3mpg, combined CO2 emissions 150 g/km – 142 g/km), with the help of 457.3 lb-ft torque peak.

All A6 models will be exclusively equipped with automatic transmission. The 3.0 TDI unit is paired with an eight-speed tiptronic and the 3.0 TFSI with a seven-speed S tronic, and both engines channel their outputs through quattro all-wheel drive as standard. In conjunction with the tiptronic transmission the quattro configuration is based on the more familiar self-locking centre differential format, while the S tronic transmission works with the ultra variant, which is capable of engaging the rear axle instantly whenever needed but decouples it during cruising to maximise efficiency.

In conjunction with the tiptronic transmission the optional sport differential can enhance handling by actively distributing the power between the rear wheels. Like the dynamic all-wheel steering, the controlled damping and the adaptive air suspension, it is integrated into the control function of the electronic chassis platform. The driver can select various driving profiles via the Audi drive select system – the wide spread from Comfort through to Dynamic is more pronounced than in the outgoing model.

The lighting design emphasises the technical character of the A6. Three headlight formats are available, the most sophisticated being the HD Matrix LED headlights, recognisable by the five horizontal lines which form the daytime running light signature and emphasise the width of the front. Above them are the dipped beam modules. Upgraded tail lights with a special light signature made up of a single horizontal line and nine vertical segments for each unit are available as an option, and the areas in between these are filled by the brake light. Dynamic indicators are included with the top-of-the-line equipment. Inside, two lighting packages are available: the ambient lighting package and the contour ambient lighting package.

The new Audi A6 will be produced in Germany at the Neckarsulm Audi facility and will become available in the UK in the summer. UK pricing and specification will be confirmed nearer to launch.
