E-cars are only suitable for short distances and are not suitable for everyday use? The range of an electric car plays an important role with regard to the success of e-mobility. Thanks to ongoing development, the alternative drive system has reached the long haul. This poses u.A. The audi e-tron sportback 55 quattro * * under proof: the e-car can be "refueled" at fast charging stations with up to 150 kwh. This means that the vehicle is ready for another stage in about 30 minutes *. Try it out for yourself with the range calculator and read our tips on the subject of e-cars in winter.

How far can I get in city traffic, on country roads or on the highway, taking various factors into account?? The range calculator for the audi e-tron and audi e-tron sportback offers you an answer to this question. In contrast to the WLTP cycle, air conditioning is assumed to be switched on. With a particularly energy-efficient driving style (e.g. A constant medium speed or no air conditioning) higher ranges are achievable. For realistic driving profiles, acceleration and deceleration phases are included based on experience values.

The range that can be achieved with an e-car depends on various factors, such as z.B.:

Individual driving style
Selected driveselect mode
Switched on electric consumers
Vehicle configuration and loading
Climatic conditions (weather)

Special features in winter operation

In winter operation, there are other factors that can reduce the range of your e-car, such as z.B.:

Increased rolling resistance with winter tires
Low temperatures as well as aggravated road conditions additionally increase rolling and aerodynamic drag
Switched on electrical consumers
Heating necessary sensors for assistance systems to avoid icing up
Additional increase in rolling resistance due to attachments such as z.B. Roof racks, roof boxes, etc.

Protect the battery from low temperatures and park the vehicle in a location that is as protected from the weather as possible

Adapted anticipatory driving style in driveselect "efficiency" mode and anticipatory driving style in accordance with the suggestions from the vehicle’s efficiency assistant

Reduce electric consumers like z.B. air conditioning, defrost, heated interior, mirrors, windshields and seats

Observing the tire pressure

Reduction of the load

Avoidance of unnecessary and unused attachments such as z.B. Ski racks, roof boxes, etc.

Frequently asked questions

1. Drive with foresight and watch your speed.

2. Use the "efficiency" drive select mode. This is designed for particularly economical driving.

3. Pay attention to the vehicle level. Reduce aerodynamic drag by lowering the vehicle’s height using audi drive select’s "sport" or "efficient" mode.

4. Pay attention to auxiliary consumers such as air conditioning, radio, headlights, heated rear window. These also use the energy from the battery.

5. Avoid driving with attachments like z.B. Roof rack when it is not required.

6. Use the ECO tire pressure.

7. use preconditioning (programming the time of departure) when the vehicle is still connected to the charging station.

8. Use the range mode (restricted driving mode).

The range indicator is calculated from the battery level, the current thermal conditions and the last consumption values. Due to the high efficiency of the vehicle and the e-drive, any driving resistances have a disproportionately high effect compared to an internal combustion vehicle. You can find the individual consumption value of your vehicle in the myaudi app under "equipment details/technical data/consumption".

The range is influenced in particular by the following factors:

– thermal conditions (cold/heat)

– tires (z.B. Winter tires)

– road conditions (wet, snow)

– auxiliary consumers (heating, seat heating, rear window heating, air conditioning). )

– load (passengers, luggage)

– side and head wind

The range management system in the audi e-tron informs the customer of the remaining range available in every situation. Your audi e-tron alerts you in good time when the power storage unit is almost empty. For this, the driver is warned at a remaining range of 100 km and again at a remaining range of 50 km. If necessary, automatic route guidance to the nearest charging station begins. In addition, when the remaining range is low, your vehicle will automatically switch to energy-saving mode to maximize the remaining range.

The right "momentum" for the smart city

The development of German cities into smart cities is ambivalent. But the road to the smart city still holds uncertainties for some cities. Organizational challenges in particular are hampering the efforts of some municipalities to develop local digitization strategies and take concrete steps toward implementation.

Sights are on every corner in berlin – unlike parking spaces. We have tips on the best places to park in the city center and at the airports in Schonefeld and Tegel.

Berlin probably has as many facets as kebab stores – and that is supposedly far more than 1.000. Describing the capital in one sentence is practically impossible. "poor but sexy" is berlin, former mayor klaus wowereit once said. today, the city is staging itself in a marketing campaign as the "capital of freedom". And "coolness-wise, the city is bursting at the seams," warbles the berlin band seeed in their capital city anthem "dickes b.

With more than 3.5 million inhabitants, not everything runs smoothly even in germany’s largest city by far. Rents keep rising and the streets are often at a standstill – berlin is the capital of congestion. According to a study by traffic data provider inrix, berlin motorists spent an average of 154 hours in heavy traffic or congestion in 2018. When they finally arrive at their destination, they despair of finding a free parking space. At least: tourists are compensated by the numerous sightseeing attractions.

Parking in the city: help from your cell phone

If you want to get to the sights by car, you often have to have patience, time and money to find a parking space. There are only a few free parking zones – especially in the city center and thus close to the many attractions. Parking fees in the parking garage are often expensive. If you are lucky, you can park your car for free on the strabe des 17. June between the Victory Column and the Brandenburg Gate.

To make parking faster and more convenient for drivers in the future, the capital is relying on smart solutions. This is how you can easily find a free parking space with your cell phone using smart parking apps. Thanks to real-time navigation, drivers can find the parking space quickly, and the parking ticket can also be paid for cashlessly on a cell phone.

berlin-schonefeld airport: free parking with park and ride

Berlin, like all other german cities, relies on parking space management, which means that car drivers can rarely park for free. By the end of 2019, the city wants to extend parking management to 75 percent of the city center. Districts such as schonefeld and mitte are already planning new parking zones – with the aim of calming traffic and improving air quality. In addition, drivers will soon have to pay higher fees to park on the street: the price is set to rise from an average of two to three euros per hour.

Berlin also wants to ease traffic congestion with the help of park and ride and offers free parking at some train stations on the outskirts of the city. From there, car drivers can transfer to the train and save themselves the hassle of looking for a parking space in the city center.

By the way, park and ride is also a good way to get to the airports of tegel and schonefeld in berlin. For example, the free altglienicke P+R parking lot is only a few kilometers from schonefeld airport. the streetcar runs from here at close intervals. The P+R parking lot at the S-Bahn station in Berlin-Gruenau is also free of charge. From there, for example, buses travel to schonefeld airport without stopping. The driving time is about 15 minutes. To get to schonefeld by S-Bahn, travelers only have to change trains once.

tegel airport: it gets expensive right at the airport

It’s not quite as easy for drivers to get from a park-and-ride lot to tegel airport as it is to get to schonefeld. From the S-Bahn and U-bahn station jungfernheide, which is located to the south of the airport, there are buses that run without any intermediate stops. Unfortunately, however, there are very few parking spaces here. If you are not lucky, you will have to pay for parking. However, the parking spaces directly at the airport can cost up to 199 euros per week. It is cheaper to park in parking spaces a little further away. From there, providers often take travelers to the airport by shuttle service.

Berlin sights: the agony of choice

Berlin is packed with so many sights that it’s hard to choose what to see on a short city trip. When you think of berlin’s most famous landmarks, the brandenburg gate inevitably comes to mind. The sights at pariser platz attract thousands of visitors every day, who like to have their pictures taken in front of the symbol of german reunification. the brandenburg gate is located in berlin’s Mitte district and, thanks to its central location, is a hub for tourists.

A symbol of the division of germany is also high on the list of visitors to the capital: the berlin wall. The traces of the border fortifications built in 1961 – once about 155 kilometers long – have almost disappeared today. tourists still find remains of the berlin wall, which are still about 1.5 kilometers long. by the way: paving stones at the brandenburg gate today remind us of the former course of the berlin wall. in the district of berlin-friedrichshain you will also find the east side gallery – a permanent open-air gallery on the longest still preserved section of the berlin wall.

sightseeing: alexanderplatz as a starting point

alexanderplatz in berlin-mitte is the ideal starting point for a sightseeing tour. regional trains, streetcars, buses as well as suburban trains and subways run at the city’s major transportation hub. and from alexanderplatz other sights can be reached on foot – for example berlin cathedral, hackescher markt, berlin city hall, brandenburg gate, berlin television tower or museum island.

potsdamer platz is also a top sightseeing spot in the capital and is also a good starting point for exploring the city. From the shopping district with stores, restaurants, cinemas and the theater, you can easily reach the gendarmenmarkt, checkpoint charlie and the brandenburg gate on foot. also very close to potsdamer platz: the zoological garden with victory column and zoological garden.

The new berlin brandenburg airport, a permanent construction site next to schonefeld airport, has also been used in the meantime – but only as a parking lot. In 2018, the car manufacturer volkswagen rented parking spaces at the airport to accommodate around 8.000 cars in temporary storage at short notice. And berlin was once again one facet richer.

Where does long covid come from? scientists increasingly see symptoms as signs of autoimmune disease

The symptoms of long covid increasingly resemble those of an autoimmune disease. Indications that a certain type of antibody causes inflammation in patients with long covid.
The antibodies attack the body’s own proteins and are a characteristic feature of many autoimmune diseases.

patients with long covid may soon get the long awaited answer to their question why they still suffer from the consequences of corona infection. The national institutes of health (NHI), an agency of the u.s. department of health and human services, now plans to conduct a $470 million study to investigate the causes of long covid. However, some clues to its possible origins are already emerging: the virus could trigger an autoimmune response – which then causes persistent symptoms such as fatigue, shortness of breath, loss of smell, muscle pain or brain fog.

"we can’t yet say with complete certainty that it’s an autoimmune disease, but it’s starting to look that way," university of arkansas physician john arthur told business insider in an interview. Arthur and his research team have just published a study in the journal plos one.

the researchers’ suspicion, which was confirmed in the study: some patients with long covid develop so-called auto-antibodies during infection. These attack the body’s own proteins, which in turn can lead to harmful inflammation. Such a reaction is typical for autoimmune diseases – and could also be the trigger for long covid, according to the research team. "so far, everything kind of fits together. We’re just not quite there yet in terms of understanding what’s going on behind the scenes," says Arthur.

If the theory of the researchers around john arthur is confirmed, this would have implications for how long covid patients are treated. Certain antihypertensive drugs could then be used, for example, to stop the harmful inflammatory response. In addition, some study results suggest that the corona vaccines may also help alleviate the long covid symptoms. This may be due to the regulation of antibodies by the vaccines, the research team suggests.

In many long covid patients, the immune system seems to fight their own antibodies

At least one-third of all corona patients have at least one persistent symptom of covid-19 over twelve weeks or longer. This is the result of a recent study that has yet to be verified by independent experts. Scientists have been looking at what the reasons for long covid might be for more than a year.

"i see a lot of younger patients with chronic covid symptoms. Many of them, however, had no health problems before the corona infection, especially no lung disease," says dixie harris, for example. She is a pulmonologist at intermountain healthcare in utah, u.s. "they were totally active beforehand, running marathons and playing sports. Now they rely on external oxygen."

researchers know that the bodies of sick people develop antibodies to neutralize the coronavirus. However, in many long covid patients, the immune system seems to mistake these antibodies for a foreign threat. The body then forms auto-antibodies to fight its own supposedly harmful antibodies.

arthur’s team analyzed blood samples from 32 long covid patients who had donated plasma at the university of arkansas. Another 15 who had been treated at the local hospital were also included in the study. The analysis shows that about 81 percent of the plasma donors and 93 percent of the hospitalized patients had developed a certain type of auto-antibody. These inhibited the so-called ACE2 enzymes, which serve as an "entry port" for the coronavirus to enter the cells. But at the same time, these enzymes are essential for calming down the immune system. If there are not enough enzymes of this type, the immune system can cause too much inflammation. "inhibition of the ACE2 enzyme basically clogs up the whole system," explains arthur. "it’s like having a clump of hair down the drain pipe. The water can no longer drain away and starts to accumulate on top."

However, further research is needed to provide a clear explanation. It is not yet possible to say with certainty whether these ACE2 antibodies actually cause long covid, the researchers say. For example, it is not yet certain whether severe infections produce more auto-antibodies than mild illnesses. Results of a study published in may in "nature" had pointed to this possibility. John arthur emphasizes, however, that long covid is also found in people with mild disease progression.

Scientists consider antihypertensive drugs as possible treatment

However, the results of the study by arthur’s team suggest that there are potentially other treatment options for long covid patients than those that have been used so far – such as the previously mentioned drugs that are normally used to treat hypertension.

The reason: ACE2 enzymes normally contribute to the regulation of blood pressure. They convert a substance that increases blood pressure into one that improves blood flow. Long covid could prevent this conversion process so that the substance, which increases blood pressure, could cause harmful levels of inflammation, it is thought. Possibly drugs against high blood pressure could therefore attenuate this inflammatory reaction.

At the same time, the study conducted by arthur suggests that corona vaccines may balance the levels of covid antibodies and auto-antibodies in patients with long covid. a british study published in march found that symptoms improved in 57 percent of those affected by long covid after vaccination. However, the study and its results still have to be verified by independent experts. arthur’s team also wants to do research for this. "this is one of the issues we will be looking at in the next phase," he says. "we want to gain insight into how vaccination status affects the frequency of ACE2 antibodies."
