The 4.0 TDI of the new Audi SQ7 TDI has been redeveloped from the ground up. It combines best-in-class performance with low consumption and therefore guarantees maximum dynamics. An electric powered compressor (EPC) makes its first ever appearance in a production vehicle. This device supports the work of the two turbochargers in the new Audi SQ7 TDI especially at lower revs, assuring agile starting performance. The result is dynamism without any hint of turbo lag.
The power for the EPC – which peaks at 7 kW – is provided by a 48-volt electrical subsystem. The SQ7 TDI is the first automobile from Audi to feature this higher-power electrical system. In conjunction with the EPC, this technical solution also paves the way for the high-performance system of electromechanical active roll stabilization. To meet its high power requirements and short-term energy 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. A DC/DC converter connects the 48-volt and 12-volt electrical subsystems.
The electromechanical active roll stabilization is a new technological solution in this market. It makes controlled, sporty handling possible. The car rolls less on bends, lateral inclination is markedly reduced and the tendency to understeer is kept even better in check. This enables higher lateral acceleration and thus faster cornering.
The base price for the new Audi SQ7 TDI in Germany is EUR 89,900. This already includes popular equipment options from the Audi Q7 worth around EUR 10,000, all supplied as standard. They include LED headlights, adaptive air suspension with S-specific settings, a 3-spoke sport steering wheel with multifunction buttons and shift paddles, a larger 85-liter (22.5 US gal) tank, an anti-theft alarm, electrically adjustable, heated sport seats in Alcantara and leather, 20-inch wheels, sporty-contoured bumpers and door trim strips, plus brushed aluminum inlays.
As an option, Audi can also equip the new SQ7 TDI with the advanced dynamic driving package, which comprises three technology modules: quattro with sport differential, all-wheel steering and the new electromechanical active roll stabilization.
