The 4.0 TFSI in the new 2020 Audi RS 6 Avant delivers 600 horsepower (441 kW) and 590 lb-ft (800 Nm) of torque, which is maintained at this high level between 2,050 and 4,500 rpm. In just 3.6 seconds the high-performance station wagon sprints from zero to 100 kph (62 mph). And in a mere 12 seconds the 2020 Audi RS 6 Avant reaches 200 km/h (124). Top speed is electronically governed at 250 kph (155 mph). With the optional dynamic package, the RS station wagon does up to 280 kph (174 mph) or even up to 305 kph (189 mph) with the dynamic package plus.
Thanks to the 48 volt main electrical system the twin-turbo V8 combines maximum performance with high efficiency. A belt alternator starter lies at the heart of the mild-hybrid system (MHEV). Up to 12 kW of power can be recovered during light deceleration and stored in a separate lithium-ion battery. If the driver takes their foot off the accelerator at a speed between 55 and 160 kph (34.2 to 99.4 mph), the drive management selects one of two options: Depending on the driving situation and setting in the Audi drive select the new RS 6 Avant recovers energy or coasts up to 40 seconds with the engine switched off. Pressing the accelerator makes the belt alternator starter restart the engine. MHEV technology allows for start/stop operation at speeds of up to 22 kph (13 mph). Fuel savings of up to 0.8 liters per 100 kilometers are possible in everyday driving.
The cylinder on demand (COD) system is also onboard as another efficiency component. At low through intermediate load and speed, it deactivates cylinders 2, 3, 5 and 8 in the high gears by switching off injection and ignition and closing the intake and exhaust valves. In four-cylinder operation the operating points in the active cylinders are displaced toward higher loads in areas of the characteristic map with higher efficiency, while the deactivated cylinders largely run without losses, like gas springs. When the driver presses the accelerator pedal, they are reactivated instantly.
For all its efficiency the 4.0 TFSI develops a sporty, voluminous V8 sound. The driver can influence the engine sound using the Audi drive select system. The optional RS sport exhaust system with black tailpipe trims ensures a maximum sporty sound experience. In the customizable RS1 and RS2 modes, customers decide themselves whether the sound should be sporty or balanced.
The new Audi RS 6 Avant will go on sale in dealerships in Germany and other European countries by the end of 2019.
