Audi innovation: SQ7 TDI

audi1

Following the launch of the SQ5, Audi is now applying the concept of a diesel-engined S model to the Q7 model line.

The 4.0 TDI has been newly developed from the ground up. It combines best-in- class performance with low consumption and guarantees maximum dynamics. The V8 engine has a displacement of 3,956 cc. The two exhaust-gas turbochargers are activated selectively according to the concept of sequential charging, since exhaust gas only flows through one turbocharger at low and intermediate load. The second turbine is only activated at higher loads. An electric powered compressor (EPC) augments the work of the two turbochargers, particularly in the lower engine speed range, providing for extremely dynamic off-the-line performance.
With 320 kW and 900 Nm of torque between 1000 and 3250 revolutions per minute, the SUV sets new benchmarks in the segment. It accelerates from 0 to 100 km/h  in 4.8 seconds; top speed is 250 km/h  (governed).

High efficiency: The eight-speed tiptronic
The redesigned eight-speed tiptronic is impressively efficient. It changes gears extremely quickly and efficiently, and at high speeds allows coasting at idle. A self-locking centre differential is the heart of the quattro permanent all-wheel drive system. It is compact, lightweight and interacts very precisely with the suspension control system.
The maxim of lightweight construction also applies to the suspension – its links are made primarily of aluminum. Electromechanical power steering, the Audi drive select driving dynamics system and adaptive air suspension with S-specific tuning are standard.

Body roll stabilisation
A new solution in the competitive environment is the electromechanical active body roll stabilisation. Here a compact electric motor with a three-stage planetary gearbox separates the two halves of the stabilizer. On an uneven road surface, they are actively decoupled from one another, resulting in improved ride comfort. During sporty driving, the tubes are interconnected and twisted against each other. That significantly reduces body roll, i.e. the lean of the car.

Five seats or seven
Audi offers the SUV with a choice of 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 folds up and down electrically.

Potent computing power: Infotainment and Audi connect
MMI navigation plus, the optional top-of-the-line infotainment system in the SQ7 TDI, uses the second-generation Modular Infotainment Platform. Thanks to the integrated LTE module and the Wi-Fi hotspot included in the Audi connect package, passengers can surf at high speed with their mobile devices. The Audi connect package brings comprehensive online functions on board.
New on the market is the Audi connect safety & service package, which also includes the myCarManager package. With this, customers can use their smartphone to lock and unlock the car or check the vehicle status, for example.

Another infotainment highlight is the Audi smartphone interface. In the car, a tailored environment on the MMI monitor makes it easy to control smartphones with iOS or the Android operating system.

The sound systems in the SQ7 TDI are as innovative as they are upscale. In the Bang & Olufsen Advanced Sound System, the digital signal processor drives  11 channels with a total of 23 speakers in such a way that the sound is equally precise and harmonious in every seat.
Optionally, two Audi tablets can be docked in the backs of the front seats.

Driver assistance systems
The SQ7 TDI offers a wide range of 24 driver assistance systems to help drivers travel safely, fuel-efficiently and comfortably. The predictive efficiency assistant, for example, provides additional information in the instrument cluster to help the driver save fuel. The standard Audi pre sense city – an anticipatory warning and emergency breaking function for avoiding accidents and protecting pedestrians – makes the SQ7 TDI even safer.

The adaptive cruise control with traffic jam assist relieves the driver in slow-moving traffic on well-paved roads by taking over the steering in many situations. The predictive ACC enables the anticipatory adjustment of driving speed to the route and speed limits, such as when entering towns. BFM
