Major milestone reached in rigorous Audi testing programme

• 12 years of a car’s life replicated in just 19 weeks of testing
• 100th car in the Ingolstadt corrosion and aging test is an Audi A4
• Sylvia Droll, Head of Materials Engineering at AUDI AG: “Endurance test exemplifies our high quality requirements worldwide"

Ingolstadt, August 2, 2016 – Audi Quality Assurance has conducted its 100th ‘INKA’ test – on an Audi A4. The Ingolstadt corrosion and aging test is one of the toughest assessments a car has to go through at Audi. Performed at the Audi global headquarters, it simulates the challenges of 12 years of a car’s lifetime in a span of just 19 weeks. Quality Assurance uses this method to verify an Audi's effective corrosion protection and durability.

In the course of performing 100 ‘INKA’ tests, Audi Quality Assurance has completed a total of 322,500 testing hours, covered more than one million kilometres (621,371 miles) and driven through 2,800 mud tests and 1,900 salt tests.

“Audi stands for superior build quality, high-quality material appearance and high reliability – even many years after a car is first registered,” explains Sylvia Droll, Head of Materials Engineering. “The INKA test is an essential tool for assessing the quality of our models and for further optimising our production methods.”

The endurance test covers five phases. First the car is misted with salt in a climatic chamber at 35 degrees Celsius. Next it is exposed to a tropical climate of up to 50 degrees Celsius and maximum air humidity of 100 percent. In phase three, 80 halogen metal vapor lamps, each with an output of 1,200 watts, heat the body to a maximum of 90 degrees Celsius. In the process, the colours in the interior must not fade and the materials must not become brittle.

The fourth phase simulates winter-like conditions at the polar circle. At minus 35 degrees Celsius, a four-post hydropulse machine rocks the car to simulate the body torsion and strain on parts of the vehicle and engine mounts that cars endure on rough roads. In parallel – phase five – test drivers repeatedly drive through specially prepared routes on the open testing grounds.

A total of 12,000 kilometres (7,456.5 miles) are travelled with each model, including driving through saltwater and mud. At the end of the test, the quality inspectors dissect the entire car into around 600 individual parts and check these for weak points.

Audi Quality Assurance conducted the first INKA tests in 2002. Technical Development has been assessing pre-series cars using the same test method for 40 years now.

Technological trendsetter can now be configured on audi.co.uk and ordered in UK Audi Centres nationwide

• New 435PS and 900Nm Q7 flagship priced from £70,970 OTR, available to order now with first deliveries starting in August
• Standard specification includes S-specific interior and exterior details, virtual cockpit, adaptive S air suspension, active sound exhaust system, rear view camera and Valcona leather upholstery with S embossing
• New driving dynamics sports pack featuring quattro with sports differential, all-wheel steering and electromechanical active roll stabilization exclusive to the SQ7 TDI
• Key optional equipment also includes 22-inch diamond-cut alloy wheels, carbon ceramic brakes, Audi Matrix LED headlights, Tour pack featuring Traffic Jam Assist and night vision

Another pioneer joins the UK Audi range this week – the new SQ7 TDI, priced from £70,970 OTR, is notable not only as the first ever ‘S’ version of the Q7 luxury SUV, but also as the first series production car to incorporate new electric powered compressor (EPC) technology that consigns ‘turbo lag’ to history. Supporting two sequentially activated turbochargers, the EPC helps to generate pulling power that is unparalleled in this class, and the V8 TDI-powered Q7 flagship is able to deftly deploy it thanks to a chassis bolstered by state-of-the art electromechanical active roll stabilisation. The integration of both systems is made possible by a powerful new 48-volt electrical subsystem which makes its Audi debut in the Q7 and will be the springboard for numerous revolutionary new technologies in the Audi models of the near future.

As it is electrically driven and therefore not dependent upon exhaust flow like conventional turbochargers, the revolutionary electric powered compressor (EPC) brings its force to bear on the 4.0-litre, eight-cylinder TDI in less than 250 milliseconds, so its benefit is palpable from the second the accelerator pedal is depressed.

Whenever the exhaust gases provide sufficient energy two sequentially activated ‘conventional’ turbochargers take over, all-the-while accompanied by a compelling V8 bellow from the active sound exhaust system.

Now developing 435 PS and 900 Nm (663.8 lb ft) of torque, the redesigned V8 BiTDI firmly stakes this performance flagship’s claim as the most powerful diesel SUV on the market. With the electric powered compressor (EPC) supporting the work of the two turbochargers, especially at lower revs, step-off performance is exceptional, and this is reflected in a 0-62mph sprint time of just 4.9 seconds. Top speed is limited to 155mph, and in the New European Driving Cycle (NEDC), the SQ7 TDI returns up to 39.2 mpg combined. This corresponds to CO2 emissions of 190 g/km.

TDI debut for Audi valvelift system (AVS)

The exhaust, which each cylinder discharges from both exhaust valves, flows through separate channels within a dual-flow manifold system. Each exhaust valve supplies one of the two sequentially activated turbochargers. The Audi valvelift system (AVS), which makes its debut in a TDI engine in the SQ7 TDI, keeps one valve closed at low and intermediate load and rpm so that the entire exhaust flow reaches the so-called “active” turbocharger. If engine speed increases to the range between 2,200 and 2,700 rpm, the respective second exhaust valve is opened and the second turbocharger is also activated.

The power for the EPC – which peaks at 7 kW – is provided by a 48-volt electrical subsystem, which also makes its Audi debut here. To meet its high power requirements, there is a separate 48-volt lithium-ion battery in the electrical subsystem beneath the luggage compartment. It has a peak output of up to 13 kilowatts, and is connected to the more familiar 12-volt electrical subsystem by a DC/DC converter.

In conjunction with the EPC, the 48-volt electrical subsystem also paves the way for incorporation of an electromechanical active roll stabilisation system. Here, a compact electric motor with a three-stage planetary gearbox separates the two halves of the stabiliser. On an uneven road surface, they are actively decoupled from one another, resulting in improved ride comfort, but during faster driving they are interconnected and twisted against each other. With this advanced stability system on board the SQ7 TDI rolls less in bends and the tendency to understeer is kept even better in check, enabling higher lateral acceleration and thus higher cornering speeds.

Sport differential for the first time in Q7

In the interest of agility the sport differential actively controlling torque distribution between the rear wheels can also be specified for the first time in the history of the Q7 in the new SQ7 TDI. All-wheel-steering is also available to promote even greater stability at higher speeds by turning the front and rear wheels in the same direction, and to aid low speed manoeuvrability in urban situations by turning them in opposing directions.

Housing all this technological accomplishment is an accommodating yet outstandingly aerodynamic body with a low 0.34 drag coefficient and the lowest weight in the class, made possible as a result of innovative multimaterial construction blending aluminium and steel in precisely the right proportions and locations. Underpinning it is standard S-specific adaptive air suspension that reacts to the movements of 20-inch alloy wheels and is controllable via the standard Audi Drive Select adaptive dynamics system.

Visual cues to the ranking of the SQ7 TDI include a unique radiator grille design, an aluminium finish for the side air inlets, mirror housings and door inlays, LED headlights with a striking double-arrow light signature and an exhaust system branching into four rectangular tailpipes.

Under the skin, seven comfortable seats across three rows are upholstered in high quality Valcona leather, and the 235 litres of luggage space can be expanded to up to 1,890 litres helped by the standard electrically folding third seat row. Accessibility is also aided by the standard powered tailgate. Occupants enjoy plenty of space as well, along with a generous quota of equipment as befits a model not only bearing the S badge, but also exemplifying Audi technological ingenuity.

Audi Virtual Cockpit as standard

The fully digital Audi Virtual Cockpit is one of the many standard features, as is the Audi smartphone interface and MMI Navigation plus with the fingertip-sensitive MMI Touch pad control. Also new to the Q7 range is an embedded SIM card which immediately brings the benefits of Internet-based Audi Connect services to the car at no additional cost and without the need to insert a separate data-only SIM as was previously necessary. Google Earth mapping, Google Street View, news, weather, online traffic, flight and train information as well as local fuel prices and entertainment options are among the features available via the 7-inch MMI monitor and the 12.3-inch Audi Virtual Cockpit display.

Audi Connect infotainment is offered on a three-month trial basis, or is included for three years if the optional Technology Package is specified. This cost-effective package also includes the Audi phonebox for wireless smartphone connection to the car’s antenna and wireless, inductive charging (according to the Qi standard) and a head-up display projecting key information onto the windscreen in the driver’s field of vision.

The Audi connect portfolio also includes a new permanently active element known as Audi Connect safety & service, which also integrates the myCarManager package. Thanks to this feature, help from the emergency or roadside assistance services is always available at the touch of a roof lining-mounted button (or automatically in the unfortunate event of a more serious incident), and via myCarManager customers can use their smartphone, in conjunction with the Audi MMI app, to precisely locate their car, lock and unlock it or check if the lights have inadvertently been left on.

Among the more indulgent options available for the new SQ7 TDI are alloy wheels of up to 22 inches in diameter, Matrix LED headlamps capable of diverting their beam around oncoming and leading traffic, S Sport seats plus with contrasting diamond stitching and two optional ‘3D’ surround sound systems from Bose and Bang & Olufsen, the latter offering up to 1,920 watts of music power.

From a more safety and efficiency-conscious perspective, customers can choose from a wide range of 24 optional driver assistance systems. The predictive efficiency assistant, for example, provides additional information in the instrument cluster to help the driver save fuel, while adaptive cruise control with traffic jam assist relieves the driver in slow-moving traffic on well-surfaced roads with clearly defined markings by taking over the steering in many situations.

The Audi music interface integrates portable media players into the Audi Multi Media Interface (MMI).

You can select artists, albums, tracks or genres with the MMI controls or the multifunction steering wheel. The system is capable of communicating with a wide range of portable media players and USB storage media.

Your media player remains stowed away in the glove box or centre console during the journey, and is connected to the Audi music interface by a cable from Audi Genuine Accessories®. This cable not only transmits the track information and music to the Audi music interface, but also recharges your media player at the same time.

With an optional Bluetooth® adapter the Audi music interface is also capable of wireless music playback from suitably equipped mobile telephones and media players. Data is transferred using Bluetooth audio streaming (A2DP), which requires a terminal device with A2DP capability.

The range of control options available for the media player via the MMI and multifunction steering wheel depends on the player and adapter used. Exact information on functions and any restrictions that apply is available in the Audi database for mobile devices or from your Audi dealership.
