The second generation of the A7 was revealed in October 2017, officially launched in Germany in February 2018, and has been on sale in Europe since late 2017 and made its debut for the North American market at the North American International Auto Show in Detroit on 12 January 2018.

At launch, the A7 was powered by a six-cylinder petrol engine making 250 kW (340 PS; 335 bhp) and 620 N⋅m (460 ft⋅lbf), an engine also used in the new Audi A8. Further engines will follow soon after the start of production.

All units will receive a 48-volt vehicle electrical system, which together with the belt alternator starter (BAS) comprises the MHEV system (Mild Hybrid Electric Vehicle).
