Audi e-tron GT Quattro / Electric car for the circuit and to the family

The novelty in the Audi e-tron series takes over technology from the company’s colleague Porsche Taycan, which means that it is already the second model on the market with an electric system operating at 800 V. This system is very suitable for vehicles with high performance and high-capacity battery. , because it allows the use of cables with a smaller cross – section for the transmission of high powers, thus simplifying the construction and reducing the weight.

Another advantage is the possibility of charging the battery with a higher output, not only for external charging, but also for recuperation. The battery has a capacity of 93.4 kWh, of which 86 kWh is used. The drive is provided by a pair of electric motors, the front has an output of 175 kW and the rear 320 kW. The system power is 350 kW with a torque of 630 Nm. In the Overboost mode, the power can be increased up to 390 kW for a short time during 2.5 s. Thanks to this, the Audi e-tron GT accelerates from 0 to 100 km / h in 4.1 s, the maximum speed is limited to 245 km / h. The stated range is 452 – 488 km, which can be agreed with. During the test, we reached 468 km within the districts and the city with a 20% share of the motorway. However, the vehicle also has an efficiency mode, which uses only the front electric motor and allows driving up to a speed of 140 km / h. It can reach a range of over 500 km in urban conditions. Due to the power of up to 175 kW, driving with it is also relatively fast and there is no problem with overtaking. This mode is also suitable when driving on the highway, because the chassis is reduced to a minimum after its engagement, so that the car takes full advantage of excellent aerodynamics. The e-thron propulsion system uses state-of-the-art technology. An interesting feature is the two-speed automatic transmission on the rear axle, which significantly helps when starting and allows driving at speeds of up to 245 km / h. At normal speeds, it contributes to lower consumption. Sophisticated aerodynamics also contribute to excellent driving performance. Most of the front mask is full, providing an excellent wrap. In the lower part, there are cooling air intakes for the heat pump and for the brakes. The air is brought through the system of ducts exactly where it is needed. The exhaust behind the front fender also takes care of ventilation. The entire lower part is completely covered to achieve the smallest possible vortex and is terminated by a massive diffuser in the rear part. On the upper side of the luggage compartment door, there is an electrically retractable spoiler, which serves to improve the downforce at higher speeds. It extends automatically at a speed of about 120 km / h, but it can also be extended manually. When we talk about the luggage compartment, it is large enough for a holiday trip and in the front there is another, smaller one, which can be used to store charging cables.

Consumption is surprisingly low for what a large car it is, and in Comfort mode we usually reached 20 – 24 kWh / 100 km. In efficiency mode it was from 18 to 20 kWh / 100 km. Of course, it depends on the way you drive. During the whole test, the consumption stabilized at 23 kWh / 100 km, but we also drove on the highway and overall we drove the car, so there is certainly a potential for much lower.

Recuperation can work automatically or manually, even if the braking effect is weaker than other electric cars. During braking, however, it works with an output of up to 265 kW, which significantly simplifies the operation of mechanical brakes. Also worth noting is the possibility of DC charging with an output of up to 270 kW, which, together with the Porsche Taycan concern, is the highest value on the market so far. This way, you can charge the battery from 10 to 80% in just 21 minutes. On 500 V chargers with an output of “only” 150 kW, the same charge still takes an excellent 31 minutes. The three-phase AC charger has an output of 11 kW and you can charge the battery in 10 hours. Optionally, you can have a charger with a power of 22 kW, which halves charging.

Of course, such a car cannot do without a number of assistance systems that make driving easier and contribute to safety. As part of the Audi Pre Sense package, there is also an adaptive driving assistant with intelligent speed transfer from the database, but also according to traffic signs and the current situation. There are safety systems to prevent collisions when turning, reversing or getting into the road, automatic braking with detection of pedestrians or cyclists and much more. Interesting is the parking assistant plus with the possibility of remote control using a smartphone. When parking, you go around the parking lot and let the system find a free space. You choose whether you want to park longitudinally or transversely, front or rear and either hold down the parking button and let the car park, or choose to park via mobile. Get out, launch the MyAudi app on your mobile, and follow the instructions. The safety button appears, which you must hold on the display in the same way as in the cab. Then just check how the car is doing. If necessary, you can release the button and the vehicle will stop immediately. The system worked very well and we never had a problem. In addition to parking, it can also park from the longitudinal and transverse places forwards and backwards. This is very useful if someone is blocking you in the parking lot and you can’t get in the car.

Outdoor lighting is, of course, completely entrusted to LED technology. The lights will welcome you with an interesting animation. The front adaptive headlights with LED matrix technology are complemented by laser high beams, which operate at speeds above 70 km / h on straight sections and more than double the range of the headlights. The lights are, of course, controlled fully automatically.

Audi has equipped the e-tron with a special synthetic sound, which is primarily intended to alert pedestrians. However, in the tested piece we also had an optional sports sound reminiscent of sitting in a sports car. I am not in favor of such “improvements”, but I believe that it can help some customers switch from internal combustion vehicles.

When you sit in the cab, it is immediately clear to you that you are sitting in a sports car. Despite the fact that the seats have electric control, heating and ventilation, you sit really low. The seats have an excellent and adjustable side guide and sit comfortably in them. Unlike the classic e-trons 50 and 55, the cabin is more designed than in the classic models. Air conditioning and other systems have direct mechanical buttons, which I really appreciate considering that it is a sports-tuned model. Here you will find the 12.5 “Audi virtual cockpit display and the 10” touch screen MMI multimedia system. These are complemented by a color projection head-up display while driving, which displays all the information needed while driving. The steering wheel control is also push-button with two rotary rollers. The multimedia also has its control on the center console, which will be appreciated especially by the passenger. We also had the vehicle equipped with the additional Bang & Olufsen premium sound system, which can take care of excellent listening to music as if you were at home in the living room. Smart navigation includes e-tron-specific features that allow you to plan a route with a preference for ultra-fast chargers along the way. Of course, E-tron also supports Audi connect services, which can be used to access the vehicle remotely via a smartphone. In addition to checking the condition of the vehicle and charging, charging, air conditioning, locking and other functions can also be controlled. For customers with e-tron vehicles, the manufacturer offers the Audi e-tron Charging Service, which allows charging at more than 210,000 charging points within Europe, including the Ionity network, where the user can charge for a price of 0, using a single account and a mobile application or card. 31 euros / kWh. Owners of e-thrones with the Transit tariff have charging for the first year without a monthly fee.

The Audi e-tron GT Quattro is a fun vehicle and driving it is very addictive. Thanks to the excellent air suspension, the pivoting of the rear axle and the excellent weight distribution, it holds very well in corners and the suspension can cope without bouncing even in our often neglected districts. Noise penetration into the cab is minimal and driving is a real experience. I really appreciate enough space for the crew in the back seats and ventilation of the front seats. Thanks to the pivoting of the rear axle, the car can be maneuvered very well even in cramped spaces.
