373 kW (507 PS) and 770 Nm (567.9 lb-ft) of torque that is constantly available from 2,000 to 4,000 rpm: The 4.0 TFSI has an easy job with the Audi SQ7 and the Audi SQ8. The twin-turbo V8 accelerates both models from zero to 100 km/h (62.1 mph) in 4.1 seconds, and it takes just 3.8 seconds to sprint from 80 to 120 km/h (49.7–74.6 mph). The electronics limit the propulsion at 250 km/h (155.3 mph). Depending on the equipment, the SQ7 TFSI consumes between 12.1 and 12.0 liters of fuel per 100 kilometers (19.4–19.6 US mpg), which corresponds to CO2 emissions of 278 to 276 grams per kilometer (447.4–444.2 g/mi). For the SQ8 TFSI, these figures are also 12.1 to 12.0 liters (19.4–19.6 US mpg) and 276 to 275 grams of CO2 (444.2–442.6 g/mi)).

The 4.0 TFSI, which draws on 3,996 cm3 of displacement, is a high-tech engine. The cylinder barrels in the lightweight aluminum engine block are covered with a layer of iron that is applied by means of plasma spraying. It reduces the amount of friction and therefore also reduces both fuel consumption and wear. A special efficiency technology is activated when driving with a moderate style: The cylinder on demand (COD) system deactivates four cylinders temporarily by switching off the injection and ignition and keeping the intake and exhaust valves closed.
The cylinders must be well filled when the driver accesses the full performance of the 4.0 TFSI. For this purpose, the intake and exhaust camshafts can be adjusted by a crank angle of 50 degrees, depending on the operating conditions. This precisely controlled valve overlap ensures that the gas exchange and combustion chamber filling are always adjusted at lightning speed.

The two twin-scroll turbochargers, each of which supplies one cylinder bank with up to 1.5 bar of pressure (relative), also enable a gas exchange with virtually no loss. This results in harmonious power delivery and spontaneous response time. The cylinder heads are designed with the intake side on the outside and the exhaust side on the inside, while the turbochargers and their intercooler are fitted in the 90-degree inner V. This layout enables short gas paths between the outlet duct and the drive side of the exhaust turbine with minimal flow loss.

Its 1-3-7-2-6-5-4-8 ignition sequence gives the 4.0 TFSI a distinct sporty and sonorous sound. There is a flap in each tailpipe of the exhaust system that modulates the sound depending on the load and engine speed. Active engine mounts reduce the transmission of vibrations to the body. Their electromagnetic actuators act as loudspeakers: They emit impulses via the membranes that correspond exactly to the engine’s vibrations but are phase-shifted by 180 degrees. According to the law of interference, the two waves largely cancel each other out.

A quickly shifting eight-speed tiptronic and the quattro permanent all-wheel drive put the power of the 4.0 TFSI onto the road. A clutch in the automatic transmission engages freewheeling when the driver takes their foot off the accelerator. In regular driving operation, the purely mechanical center differential distributes the drive torque to the front axle and rear axle at a ratio of 40:60. If traction decreases at one axle, it directs most of the torque to the other axle – up to 70% to the front or up to 85% to the rear axle.

With the optional advanced suspension package, customers receive the sport differential in addition. When cornering at high speed, it shifts the torque between the rear wheels via two multi-plate clutches, with most of the torque being transferred to the wheel with better grip at the outside of the curve. This torque vectoring makes handling even more agile and stable: When turning in or accelerating, the large sports SUV is literally pressed into the curve and understeer is heavily minimized.

Audi provides the SQ7 TFSI and the SQ8 TFSI with two sporty suspension modules as standard. The adaptive air suspension sport integrates controlled dampers. It is capable of varying the ride height of the body by up to 90 millimeters (3.5 in). The all-wheel steering consists of two components. The front axle steering, which has a sporty and direct gear ratio of 13.3:1, increases the vehicle’s agility and maneuverability considerably.
A spindle drive influences the rear wheels: At low speed, it turns them by up to 5 degrees in the opposite direction, which makes it easier to maneuver. As of a speed of about 60 km/h (37.3 mph), it turns them slightly in the same direction for improved stability during fast changes of direction in particular.
