The V8 with biturbo charging outputs 320 kW (435 metric hp) and delivers 900 N·m torque (663.8 lb-ft) between 1,250 and 3,250 rpm.

The large SUV accelerates from zero to 100 km/h (62.1 mph) in 4.8 seconds and reaches an electronically governed top speed of 250 km/h (155.3 mph). Depending on the equipment the SQ7 TDI uses between 7.6 and 7.4 liters of fuel per 100 kilometers (30.9 - 31.8 US mpg), which corresponds to CO2 emissions of 200 to 194 grams per kilometer (321.9 - 312.2 g/mi).

The 48-volt electrical subsystem feeds an electric powered compressor (EPC) that assists the two turbochargers whenever the load demand from the accelerator is high while the available energy in the exhaust gas is still low. In this case, it supplies the fresh air, which is important for combustion. As a result, the tremendous torque is available instantly at any time—when accelerating from low speeds and particularly when starting off.

The interior features sport seats, MMI navigation plus, touch operation, and the Audi virtual cockpit including performance view as standard. Pricing starts at €94,900.
