With 320 kW (435 hp) and 900 Nm (663.8 lb ft) of torque, the new Audi SQ7 TDI is the most powerful diesel SUV on the market. It also leads the competition in numerous other technical fields. Its newly developed 4.0 TDI engine features a world first: An electric powered compressor gives the Audi SQ7 TDI outstanding off-the-line performance. Yet it consumes on average 7.4 liters of fuel per 100 kilometers (31.8 US mpg).

“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 Vorsprung durch Technik,” said Dr. Stefan Knirsch, Member of the Board of Management of AUDI AG for Technical Development.

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 all-wheel steering, the rear wheels turn in by as much as five degrees, making parking easier. The more direct front-axle steering ratio of the Audi SQ7 TDI improves the handling characteristics. Depending on the situation, the rear wheels steer opposite or in the same direction as the front wheels, improving dynamics and stability.

Thanks to systematic lightweight construction, the Audi SQ7 TDI 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; the outer skin is made of aluminum. The center of mass is low – another factor for the sporty handling. The drag coefficient is an outstanding 0.34.
