With 320 kW (435 hp) and 900 Newton meters (663.8 lb-ft) of torque, the Audi SQ7 TDI* is the most powerful diesel SUV on the market. It combines first-class performance with low consumption and maximum dynamics. A number of new technologies work in conjunction to make this possible.
“In many fields of technology, the Audi SQ7 TDI is at the head of its class,” said Dr. Stefan Knirsch, Audi Board Member for Technical Development. “Its newly developed V8 engine is the first in the world to use an electric powered compressor. This was made possible by the 48 volt electrical subsystem, which also provides the energy for the electromechanical active roll stabilization. With these innovations, the SQ7 TDI once again demonstrates Vorsprung durch Technik,” said the Audi Board Member.
Enormous power: 900 Newton meters and 320 kW (435 hp)
The Audi SQ7 TDI sets new benchmarks with 320 kW (435 hp) and 900 Newton meters (663.8 lb-ft) of torque – the latter between 1,000 and 3,250 rpm. It accelerates like a sports car from 0 to 100 km/h (62.1 mph) in 4.8 seconds; top speed is 250 km/h (155.3 mph) (governed). In the NEDC, it consumes just 7.2 liters per 100 kilometers (32.7 US mpg), which corresponds to CO2 emissions of 189 grams per kilometer (304.2 g/mi). The new eight-speed tiptronic provides for fast and efficient gear changes. At higher speeds, it allows coasting in neutral.
The new 4.0 TDI produces its power from a displacement of 3,956 cc. The two turbochargers are activated selectively according to the sequential charging concept. This combines high efficiency with dynamic power development. Control is via the Audi valvelift system (AVS), which here is making its debut in a TDI. At low engine speeds, only one conventional turbocharger is active. As rpm increases, the AVS activates the second exhaust valve in each cylinder, which until then had been closed. This directs hot exhaust to the second turbocharger, activating it.
New partner for the turbochargers: the electric powered compressor
An electric powered compressor (EPC), in which a compact electric motor drives the turbine wheel, supports the turbocharger whenever it cannot draw enough energy from the exhaust flow. The big diesel engine thus develops its immense power spontaneously with no turbo lag. The electric powered compressor provides the engine with the boost pressure needed for the dynamic delivery of power in less than 250 milliseconds. Its compressor wheel spins up to 70,000 rpm. The power is therefore available immediately when the driver presses the accelerator, which is also very apparent when starting off. The power for the electric powered compressor comes from a 48 volt electrical subsystem, another innovation in the Audi SQ7 TDI. A compact lithium-ion battery stores the energy.
The new V8 TDI features new high-tech solutions in all areas. Its intake side is on the outside; the exhaust side with the two turbochargers are in the inner V. This layout provides for short gas paths and spontaneous response. The common-rail system generates up to 2,500 bars of injection pressure. More fuel enters the combustion chamber, increasing specific output while simultaneously reducing emissions at part load. Continuously variable thermal management and sophisticated measures in the crankshaft and camshaft drive reduce friction.
From comfortable to dynamic: the chassis
The 4.0 TDI is combined with potent technologies in the Audi SQ7. The result is driveability that fulfills every expectation, from extremely comfortable cruising to dynamic handling. The quattro permanent all-wheel drive distributes power between the front and rear axle in a 40:60 ratio. The suspension links are largely made of lightweight aluminum.
The optional driving dynamics package comprising three technology modules enhances the sporty character of the Audi SQ7 TDI. The innovative, electromechanical active roll stabilization permits higher lateral acceleration and thus faster cornering. It draws its power from the new 48 volt electrical subsystem. When driving straight ahead, it provides for excellent ride comfort. An electric motor, which on an uneven road surface decouples the two halves of the stabilizer from one another, makes this possible. During sporty driving, the tubes are actively twisted against each other, resulting in taut, virtually neutral handling.
The sport differential provides for precise and stable handling during fast cornering. This superior control is achieved with variable torque between the rear wheels. When turning into or accelerating in a curve, the majority of the torque is directed to the outside wheel, pushing the car into the curve.
The third technology module is the all-wheel steering. To improve agility and stability, the rear wheels turn a few degrees in the same or opposite direction of the front wheels, depending on the situation. The large SUV thus becomes significantly even more nimble, and its turning radius smaller by up to one meter (3.3 ft) – quite noticeable during maneuvering and parking.
The electronic chassis platform central control unit provides for dynamic chassis control. The electronic chassis platform control unit continuously monitors the driving situation and in a cycle of just one millisecond adjusts the handling functions for the electromechanical active roll stabilization, the sport differential and adaptive air suspension. By comparison: A blink takes roughly 100 times as long.
Electromechanical power steering, the Audi drive select system and the adaptive air suspension with S-specific tuning are standard. The brake calipers are painted black (optionally red); an optional brake system with carbon fiber-ceramic discs will be available shortly after market launch. The SUV rolls on 20-inch wheels, with wheels up to 22 inches available
as an option.
Largest range in the segment: the driver assistance systems
The range of driver assistance systems available in the Audi SQ7 TDI is extremely diverse – 24 solutions are dedicated to composed, relaxed driving and safety. The standard Audi pre sense city offers a predictive warning and emergency braking system for accident avoidance and the protection of pedestrians. The adaptive cruise control maintains the interval to the car ahead at speeds between 0 and 250 km/h (155.3 mph).
In slow-moving traffic on well-paved roads, the traffic jam assist relieves the driver by temporarily taking over the steering in many situations. The predictive efficiency assistant uses precise information from the immediate vicinity for consumption-optimized driving. Other top innovations are the turn assist, park assist, exit warning and cross traffic assist rear.
Lightweight and distinctive: body and exterior design
Thanks to the systematic lightweight construction concept, the SQ7 TDI weighs just 2,270 kilograms (5,004.5 lb) without a driver. The body is a multimaterial construction. Hot-shaped and thus extremely strong sheets form the backbone of the occupant cell; the outer skin is made of aluminum. The center of mass is low – another factor for the sporty handling.
Numerous S-specific details hone the distinctive look of the 5.07 meter-long (16.6 ft) Audi SQ7 TDI. The Singleframe grille, air inlets, upper section of the mirror caps and elements of the door trim gleam in an aluminum look. The front apron is powerfully contoured; the roof edge spoiler is wider and more distinctive than that on the Q7*. A diffuser insert with an aluminum clasp encloses the four rectangular exhaust tailpipes. SQ7 TDI and V8T emblems adorn the front, the fenders and the rear. Precision-controlled Matrix LED technology is available as an alternative to the standard LED headlights. Dynamic turn signals are standard at the rear. Twelve paint finishes are available for the SUV.
Take your pick: five or seven seats
The Audi SQ7 TDI offers the largest interior in its class, with either five or seven seats. The second row comes standard with a three-section backrest with segments that can be folded down separately. The optional third row can be lowered into the vehicle floor electronically. In the five-seater model, the basic configuration of the luggage compartment boasts a volume of 805 liters (28.4 cu ft), and this can be increased up to 1,990 liters (70.3 cu ft). With a full contingent of passengers, the seven-seater model has a luggage capacity of 235 liters (8.3 cu ft). With the third row folded down, this becomes 705 liters (24.9 cu ft) with a maximum of 1890 liters (66.7 cu ft). A power tailgate is standard.
Driver and front passenger sit on sport seats that are covered as standard in Alcantara and leather, with Valcona leather available as an option. The optional sport seats plus come factory-fitted in Valcona leather with a diamond pattern. They also feature pneumatic adjustment of the seat and backrest side bolsters plus a variable head restraint.
Additional sporty accents are provided by instruments with gray dials and white needles, a special welcome screen and S badges. The LED interior lighting can be supplemented with an optional lighting package and ambient lighting that illuminates the door sill trims and additional contours on the center tunnel console. The latter can adjusted through a range of 32 colors. Besides the three color profiles familiar from the Q7, the SQ7 TDI also offers the Sport light profile in red/white.
Controls and displays: Audi virtual cockpit, new MMI system and
The optional Audi virtual cockpit with its 12.3-inch display presents tack-sharp graphics and offers a choice of two views. In “Infotainment” mode, a central window dominates, providing a large stage for the navigation map, for example, or for lists in the phone, radio and audio areas. The tachometer and speedometer are displayed as small dial instruments on the right and left. In the classical view, the central window is smaller, and the instruments appear about as large as analog displays. The driver selects the information and the view modes, including a special SQ7 mode with boost indicator, via the multifunction steering wheel. Audi offers the top-of-the-line infotainment system, MMI navigation plus with MMI touch, as an option. It is controlled via a glass surface on the center tunnel console that provides haptic feedback after every input. The MMI logic allows for intuitive operation, including free text search and an integrated natural voice control system. A head-up display, which projects important information from the assistance and navigation systems or warnings onto the windshield, is also available.
High computing power: infotainment und Audi connect
The MMI navigation plus with MMI all-in-touch uses the second-generation modular infotainment platform. Its central computer comprises two main units – the radio car control unit and the MMX board (MMX = Multi-Media eXtension). The MMX board integrates – along with the working and flash memory – a super-fast processor that processes all online, media, voice control, navigation and telephone features.
Thanks to the integrated LTE module and the Wi-Fi hotspot, the passengers can surf at high speed with their mobile devices. Audi connect brings numerous online services on board, including traffic and parking information, fuel prices, Twitter and navigation with Google Earth and Google Street View. The Audi connect SIM permanently installed at the factory includes the flat rate data plan required to use these services. It will be available in the SQ7 TDI beginning this summer, and also permits roaming in most European countries. The driver can also purchase additional data packages for the Wi-Fi hotspot, independent of the integrated Audi connect services.
Cell phones with iOS and Android operating systems are integrated into the car via the Audi smartphone interface. Selected smartphone content can then be displayed on the MMI monitor. The Audi phone box couples smartphones with the on-board antenna and charges them inductively according to the Qi standard. Two Audi tablets are provided for the entertainment of the rear passengers. They can be clipped onto the front seatbacks and serve as a fully integrated Rear Seat Entertainment system.
The innovative Bose sound system with 3D sound is available as an option. Two of its 19 loudspeakers are mounted in the A-pillars and depict the spatial dimension of height. Or Audi will install the even more complex Bang & Olufsen Advanced Sound System with 3D sound.
Groundbreaking operation: control via app
The free Audi MMI connect app lets users transfer their calendar from their smartphone to the car. If requested, the system can speak the location, time and subject of the appointment, enter the location as a navigation destination and call the participant. With the personal POI search, interesting destinations from third-party databases can be stored in a myAudi account and transferred to the car’s navigation map via the Audi MMI connect app. Over 3,000 internet radio stations are available via the “Web radio” and “Media library” functions. This requires a data plan for the Wi-Fi hotspot.
The SQ7 TDI can also be equipped with the optional Audi connect safety & service package. This includes such functions as emergency call, online roadside assistance and Audi service request as well as remote functions that can be used with the MMI connect app on a smartphone, smartwatch or – in conjunction with the fourth generation Apple TV – from a television. Examples include locking and unlocking the car, checking where the car is parked and calling up the vehicle status.
