The eighth-generation (C8) Audi A6 celebrates its world premiere today with an all-new design and host of new technologies, the latter including those found in larger stablemates like the A8 and A7 Sportback. The new A6 is due to roll off the assembly line at Audi’s Neckarsulm plant, and will be launched in Germany in June this year.

The redesign brings the A6 in line with Audi’s new design language, and the company says a combination of “taut surfaces, sharp edges and striking lines” conveys the car’s character for sporty elegance.

At first glance, you might think you’re looking at an A8 but there are a few cues to help distinguish the two. For instance, while there is a wide, low-slung Singleframe grille up front, the headlights flanking them are shaped more similarly to those on the B9 A4. Audi offers up to three lighting systems, with the Matrix LED system being the top-of-the-line version.

Other differentiating features include the aggressive front bumper with large side inlets that is part of the optional S line exterior package. At the back, the taillights are linked by a central chrome strip, similar to the A8, but there is no long LED light bar above them. Instead, they appear to pay homage to the previous-generation C7, with updated graphics within them.

All the above-mentioned elements are enough to visually separate the A6 from the A8 (even with the sport exterior package). If you’re still not convinced, shots of the car’s profile will help clear things up, where the difference in length – the A6 is 4,939 mm long and the A8 is 5,172 mm long – becomes very apparent.

Compared to its predecessor, the new A6 is just 7 mm longer. However, the new car is 12 mm wider at 1,886 mm, and 2 mm taller at 1,457 mm. The wheelbase has also grown to 2,924 mm, which is 12 mm more than on the C7.

Audi says the revised dimensions help create a larger interior in the new A6, offering more rear legroom than before – headroom and shoulder room in the front and rear are also improved. Luggage space remains unchanged from 530 litres, but there’s more loading width, with the carmaker using two golf bags being placed horizontally as the testing metric.

As for the rest of the interior, it is largely carried over from the A7 Sportback, so there’s quite a number of displays, well, on display. For the driver, Audi’s 12.3-inch virtual cockpit should be a pretty familiar bit of kit by now, and drivers can still change the type of information they want shown to them. A head-up display projecting information onto the windshield is also available.

The two displays located between the front passengers provide access to the car’s systems via touch, with the upper one being a 10.1-inch unit and the other an 8.6-inch unit. The larger of the two handles infotainment duties for the MMI navigation plus (MMI navigation is standard) system, while the smaller one deals with climate control, convenience functions and text input.

Buyers will also get to choose from two different interior lighting packages – the ambient lighting package and the contour ambient lighting package – with the latter aimed at reproducing “the clear lines of the interior architecture and can be set to 30 different colours.” The ambient lighting package meanwhile “makes the dashboard and center console appear to float.”

The equipment list also includes a range of driver assistance systems (parked under the Audi AI umbrella), including parking pilot and garage pilot that autonomously manoeuvre the car into and out of a parking space or garage. These are part of the Park assist package, one of three available packages with the other two being City and Tour.

The Tour assist package comes with the adaptive cruise assist, which supplements the adaptive cruise control with lane-keeping technology. A zFAS central driver assistance controller handles these systems, and depending on equipment, the sensor set includes up to five radar sensors, five cameras, twelve ultrasonic sensors as well as a laser scanner.

On the mechanical front, Audi is offering two engines – one diesel and one petrol– both with quattro all-wheel drive as standard. The petrol unit is a 3.0 litre TFSI V6 (A6 55 TFSI quattro) with 335 hp and 500 Nm of torque, mated to a seven-speed S tronic automatic transmission. In this setup, 0-100 km/h is dispatched in 5.1 seconds, while the top speed is limited to 250 km/h.

The oil burner is a 3.0 litre TDI V6 (A7 50 TDI quattro) that serves up 282 hp and 620 Nm of torque, paired with an eight-speed tiptronic auto. All engines feature the brand’s 48 V mild hybrid technology, where a belt alternator starter (BAS) works together with a lithium-ion battery (mounted in the back) to allow for coasting at speeds between 55 and 160 km/h.

There’s also a start-stop function that kicks into action up to 22 km/h, and the engine is restarted from standstill predictively as soon as the vehicle in front of the car starts moving. During deceleration, the BAS recovers up to 12 kW of energy, and the system is said to reduce fuel consumption by up to 0.7 l/100 km.

Customers can choose between four suspension setups: conventional hydraulics with steel springs, sports suspension, electronically-controlled damping or self-levelling adaptive air suspension. There’s also dynamic all-wheel steering for better manoeuvrability, and based on the current speed, the steering ratio varies between 9.5:1 and 16.5:1.
