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

Business First - - FRONT PAGE -

T he 4.0 TDI has been newly de­vel­oped from the ground up. It com­bines bestin- 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 rev- olu­tions 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 my Car-Man­ager 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 well­paved 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.
