Following the launch of their smallest SUV, Audi has now revealed their most powerful SUV, the SQ7 TDI.

The SQ7 features an innovative twin-turbo system, that is helped along by an electric powered compressor (EPC). The turbochargers work in a 2-stage setup, with the 2nd turbo only activated at higher loads. This setup helps to reduce turbo-lag and improve acceleration at lower speeds, making the SQ7 TDI incredibly dynamic. This is the 1st application of this technology in a road car.

Audi-SQ7_TDI_2017_002The EPC provides the engine the boost energy needed for the dynamic delivery of power in less than 250 milliseconds. Driven by a compact electric motor, its compressor wheel spins up to 70,000 rpm. The 4.0 TDI thus develops its immense power with no perceptible lag.

The SUV sets the benchmark in its segment, with the redesigned 4-litre V8 TDI now producing 320 kW and 900 Nm of torque from 1,000-3,250 rpm, and is linked to an 8-speeds tiptronic gearbox. It can accelerates from 0 to 100 km/h in 4.8 seconds, while top speed is limited to 250 km/h. Fuel consumption is an impressive 7.4 l/100km, which means CO2 emissions of 194 g/km.

The Audi valvelift system (AVS) is also making its debut in a diesel model. The inlet and exhaust cam shafts each have 2 cam contours per valve. On the inlet side, one cam contour supports starting off in conjunction with the EPC, while the other optimizes cylinder filling and thus power at high engine speeds.


The exhaust streams from the two exhaust valves are hermetically separated, with each driving one of the two turbochargers. In the lower engine speed range, 1 valve per cylinder remains closed, so that the full exhaust stream flows to the active turbocharger. When load and engine speed increase, the AVS opens the second exhaust valves. This directs flow to and activates the 2nd turbocharger. The engine achieves its maximum output in this bi-turbo mode. The switching by the AVS enables fast and precise activation of the 2nd turbo.

Audi offers the SQ7 TDI with an optional driving dynamics pack,comprising of 3 technology modules. These include aSport Differential, Electromechanical Active Roll Stabilization and All-Wheel Steering, which allow the rear wheels to steer by as much as 5 degrees.


Thanks to systematic lightweight construction, the SQ7 is the lightest SUV in its segment, yet makes no compromises with respect to crash safety. The body features an innovative multimaterial construction. Hot-shaped and extremely strong sheets form the backbone of the occupant cell, while the outer skin is made of aluminium. The center of mass is low – another factor for the sporty handling.

Another innovative system comes in the shape of the LED and matrix LED headlights. Each Matrix LED headlight divides its high beam into 30 individual LED’s, paired with 3 reflectors. A camera on the interior mirror analyzes the traffic situation.

With this information, the control unit individually turns the diodes on and off, or dims them in 64 stages each, depending on the situation. With the millions of different resultant beam patterns, the high-end headlights superbly light up the road, without blinding other road users. Traffic signs are illuminated with less power so that the driver is not blinded by glare.


The functional range of the Matrix LED headlights also includes intelligent cornering lights, created by a shift in the light centre position. If the car is equipped with the optional MMI navigation plus, this system’s route data will trigger the cornering light to illuminate around the corner just before the driver begins turning the steering wheel.

The SUV comes with a full LED lit interior, and via the MMI, the driver can adjust the intensity and colour in several profiles and in 5 zones.

The SQ7 is offered with a choice of 5- or 7 seats. The optional 3rd row folds up and down electrically. And thanks to a wide range of equipment, the SQ7 TDI can be configured to be both sporty and elegant. Two-piece applications enable diverse material combinations and further individualization.

The SQ7 features a 12.3” display. The optional Audi Virtual Cockpit shows logically structured information in brilliant graphics. Driver ergonomics are also excellent, and operation is intuitive. The driver chooses the display mode via the multifunction steering wheel. A heads-up display, and portable Wi-Fi Hotspot, are among the options available.


The optional MMI navigation plus with MMI all‑in‑touch includes a large glass surface on the centre tunnel console that provides the finger with haptic feedback after each click. The MMI logic allows for intuitive system operation and also understands terms from everyday speech.

Audi now offer the MyCarManager package as well. With this, customers can use their smartphone to lock and unlock the car or check the vehicle status, for example.

The SQ7 also features and option 23-speaker Bang & Olufsen Advanced Sound System. The system is set so that the sounds is equally precise and harmonious in every seat.


The Audi SQ7 TDI offers a wide range of 24 driver assistance systems to help drivers travel safely, fuel-efficiently and comfortably. These include Predictive Efficiency Assistant, Audi Pre Sense City, Adaptive Cruise Control and Traffic Jam Assist.

“Following the launch of the successful SQ5, we are now also applying the concept of a diesel-engined S model to the Q7 model line. So equipped, the SQ7 TDI with a V8 TDI engine achieves the consumption figures of a six-cylinder. The new technology solution of the electric powered compressor in the SQ7 TDI is a world first in the competitive environment, with which Audi once again underscores its claim VorsprungdurchTechnik,” said Dr. Stefan Knirsch, Member of the Board of Management of AUDI AG for Technical Development.
