The electric all-wheel drive builds on the intelligent networking of numerous control systems that ensure the typical quattro properties of high traction and driving stability. Important network elements include the four-stage electronic stabilization control (ESC) system and the power electronics, which interact to help balanced handling.
With the optional augmented reality head-up display in the Q4 e-tron, Audi is taking a huge step forward in display technology. It reflects important information via the windshield on two separate levels, the status section and the augmented reality (AR) section. The information provided by some of the assist systems and the turning arrows of the navigation system as well as its starting points and destinations are visually superimposed in the corresponding place on the real-life outside world as content of the AR section and displayed dynamically. They appear to be floating at a physical distance of roughly ten meters (32.8 ft) to the driver. Depending on the situation, they appear considerably further ahead in some cases. The driver can understand the displays very quickly without being confused or distracted by them, and they are extremely helpful in poor visibility conditions.
Detailed solutions, on which the Audi aerodynamics experts have worked closely with the designers, provide another gain in range. At the front of the vehicle, there are narrow vertical bars below the headlights, which act as pre-spoilers and direct the airstream so it flows smoothly along the vehicle’s side. The effect is a gain of five kilometers. A minute step on the exterior mirror housings with a radius of 0.5 millimeters allows the airflow to cling there for longer.
The architecture of the modular electric drive system (MEB) on which the compact electric SUVs from Audi are based enables a completely new division of space. The technology components need only a little space: The high-voltage battery pack is designed as a flat block underneath the passenger compartment, while the drive unit is located in a compact arrangement on the rear axle – and on the front axle in the quattro models. The short front section houses the radiator, the electric brake booster and major components of the air-conditioning system.
The headlights of the Q4 e-tron and the Q4 Sportback e-tron are fully equipped with LEDs as standard. On request, Audi also offers the Matrix LED headlights – they lend the two electric compact SUVs a look that is full of character and unmistakable, day and night. The next stage of evolution in daytime running lights is totally new among the competition. Using the MMI touch operating system, the driver can switch between four digital light signatures at any time. Each of them generates its own theme and lends the daytime running lights an individual expression. The variant selected is activated the next time the vehicle is started.
