All Q4 e-tron models feature a large battery that provides 77 kWh of net energy (82 kWh gross).
Optimized cell chemistry has improved the DC charging power so that they charge from 10 to 80 percent in around 28 minutes.
The quattro models now achieve a maximum DC charging power of 175 kW, and the rear-wheel drive models a maximum of 135 kW.
The battery protection function automatically limits the charge level to 80 percent to extend battery life.
For both rear-wheel drive and quattro all-wheel drive, all Audi Q4 e-tron models now feature a permanently excited synchronous machine (PSM) on the rear axle.
The electric SUV benefits from an increased range and superior power delivery.
The Audi Q4 Sportback 45 e-tron, for example, reaches a range of up to 562 kilometers (349 mi) in the WLTP cycle.
The Audi Q4 45 e-tron and the Audi Q4 Sportback 45 e-tron with rear-wheel drive produce 210 kW (286 PS) and accelerate from zero to 100 km/h (62 mph) in 6.7 seconds.
The Audi Q4 45 e-tron quattro and the Audi Q4 Sportback 45 e-tron quattro with 210 kW (286 PS) take 6.6 seconds.
The top-of-the-range models Audi Q4 55 e-tron quattro5 and Audi Q4 Sportback 55 e-tron quattro6 models with 250 kW (340 PS) accelerate from a standstill to highway speed in a mere 5.4 seconds.
The top speed for all models is now 180 km/h (112 mph).
The new electric motor uses optimized thermal management for greater efficiency. The system features energy-saving cooling: Due to the geometry and arrangement of the gear wheels in the transmission as well as specially shaped components for transporting and distributing the oil, temperatures in the powertrain hardly rise at all.
With the sport suspension, the body is 15 millimeters lower.
The Audi Q4 e-tron models respond more directly to steering changes for greater sportiness and agility.
As an option, the update enables the Audi Q4 e-tron family to use assisted lane changes in combination with adaptive cruise assist for speeds above 90 km/h (56 mph) on highways for the first time.
Part of the assist package pro as well as the assist package pro and assist package, protective and warning systems plus, assisted lane changing can be activated via the MMI.
Among the optional systems, adaptive cruise control specializes in regulating the distance to the vehicle in front by accelerating and decelerating.
Audi MMI navigation plus, Audi connect Navigation and Infotainment, and the fully digital 10.25 inch instrument panel Audi virtual cockpit are now standard equipment.
The luggage compartment lid now comes as standard with an electric motor, and, in conjunction with the optional convenience key, it responds to foot gestures. Heated front seats now also come as standard.
With the update, Audi is giving the compact SUV series its own acoustic identity as an option.
All models will be audible at and beyond low speeds up to about 25 km/h (15.5 mph) to further enhance road safety.
The digitally generated driving sound, emitted via two exterior speakers at the rear and two interior speakers in the rear doors, is available from the factory as a special feature. This soundscape varies according to load and speed up to the car’s top speed.
