Optional packages include Parking, which bundles up a new park assist system that arrives in 2019, as well as a City package that includes cross-traffic alert and auto braking. The Tour package includes an onboard eco-driving aid and adaptive cruise control.
The 40 TDI models on both the A6 and A7 will be available in Sport and S line specifications, with all of the standard equipment that both of those trims bring along with them, including the latest touchscreen displays and infotainment systems.
