Audi presents Electric SUV E-Tron
At an event in San Francisco, Audi officially removed the veils from its first all-electric car. This is the SUV E-tron.
Total power is 408 hp, autonomy of over 400 km and prices starting from 80 thousand Euro. These are some numbers of the new Audi E-Tron, the first fully electric car of the German carmaker unveiled at a major event in San Francisco after some postponements. Let’s talk about a sports SUV of almost five meters with an aerodynamic coefficient of 0.27 and over 2400 kilos of weight.
One of the most futuristic technological features of this vehicle concerns the rear-view mirrors, because they are managed in a ” virtual ” way. If the exterior mirrors are reduced to simple appendices, the real function of the rear-view mirrors is delegated to two micro-cameras that postpone the images coming from the rear of the vehicle on displays installed on the sides of the dashboard.
The vehicle is very spacious inside, and can accommodate up to 5 people. The trunk is 660 liters, while the two electric motors present are powered by a 95 kWh battery pack. The latter consists of 36 modules that use lithium-ion batteries. Initially, the development will be done on two types of cells for the batteries, the flexible polymer of LG and the prismatic Samsung.
Audi has developed a liquid cooling system that transfers heat to the bottom of the battery pack using a gel that wraps each of the modules. Accuracies that allow the system to recharge at 150 kW, for the first time for an electric vehicle (Tesla vehicles are recharged at 120 kW).
The charging system of Audi can recharge the battery to 80% in half an hour and start again with over 320 km of battery life, but theoretically it can reach even higher charging voltages up to equal 350 kW and 800 volts already in development with Porsche for the Mission E.
Both engines are rechargeable with induction. Naturally, these charging methods are linked to the availability of adequate charging solutions, ie ultra-rapid charging columns and wireless charging systems. In Europe, it is necessary to set up the appropriate networks and, to this end, Audi has announced a new collaboration agreement with Amazon.
The rear engine is capable of a power of 165 kW, of which 25 kW are reserved for boost mode. As for the front engine, it is capable of 135 kW with 10 kW limited to the boost mode. A combined peak power is achieved between the two 300 kW engines which allows an acceleration from 0 to 100 km/h in 5.7 seconds.
There will be a sportier version with 3 electric engines, one at the front and two at the rear, capable of transferring torque to the theoretical limit of 2,034 nm, but not manageable by the multilink suspension that is equipped with the vehicle.
As for other technologies, the new SUV from Audi is equipped with driver assistance systems based on the use of 5 radars, 6 cameras, 12 ultrasound sensors and a laser scanner. Thanks to Audi Connect, the vehicle can be connected to the network and plan the route and stops for recharging on the basis of the available stations.
Audi E-Tron is produced in the carbon neutral plant in Brussels.
