Audi is phasing out electric vehicles in favor of hybrids

27.07.2014

Audi does not plan to actively compete in the all-electric car market. The automaker sees the highest prospects in hybrid vehicles equipped with batteries that can be charged from the mains.

Rupert Stadler, chairman of the board of directors of the German brand, spoke about Audi's plans for green cars in an interview with What Car? “We have tested electric vehicles, but it has always been clear to us that from a consumer point of view, rechargeable hybrids are better,” the top manager said in response to a journalist’s comment about how far Tesla and BMW have advanced in the electric car market.

Plug-in hybrids, which incorporate the best technologies from electric and conventional vehicles, are fuel-efficient, long-range and environmentally friendly, Stadler says.

“I spoke to Tesla owners and they said they would opt for a rechargeable Audi Q7 if it was available. We are confident that we are on the right path. Electric cars are just sitting idle in dealer showrooms and do nothing to improve the environment. We want to create cars that will sell,” said the head of Audi.

However, despite the manufacturer's skepticism towards vehicles driven only by an electric motor, such a car will still appear in the assortment of the German company. It will be the Audi R8 e-tron supercar, which is scheduled for European sales in 2015. On a single battery charge, the sports coupe can travel up to 450 km, while the maximum range of the flagship version of the Tesla Model S is declared at 502 km. Reuters previously reported that Audi is preparing several powerful electric sedans and sport utility vehicles. Rupert Stadler's words can be seen as a refutation of the news agency's data.

As explained by the chairman of the board of directors of Audi, plug-in hybrids can be created on the basis of traditional mass-produced cars with internal combustion engines using existing factory facilities. At the same time, "clean" electric vehicles using other power units require new production lines.

Stadler said plug-in hybrid versions of the Audi A6 and A8 sedans, as well as the Q7 crossover, will hit the market in the coming years. A similar modification was previously received by the Porsche Cayenne SUV. The Mercedes-Benz C-Class will also be hybrid.

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Power lines interfere with bees 23.05.2023

The wires of high-voltage power lines are surrounded by electromagnetic fields, which have a noticeable effect on the state and behavior of bees. Biologists have shown that near such lines, insects experience stress and pollinate plants worse.

Special receptors allow bees to sense natural electromagnetic fields, using them for orientation and flight navigation. But people also create such fields: they surround any wire through which electricity flows, and if the currents are strong enough, the fields can have a noticeable effect on the behavior of bees. Thus, it has already been shown that near high-voltage lines these insects become aggressive and often go astray.

A new study by Chilean biologists from the University of Talca has shown that power lines prevent bees from performing their main function for nature - to pollinate flowering plants.

To begin with, scientists conducted experiments in the laboratory. One hundred honey bees (Apis mellifera) were exposed to electromagnetic fields generated by high-voltage currents of various strengths for three minutes. The researchers found that with an increase in field energy in insects, the synthesis of heat shock proteins is noticeably - up to 50 percent - increased, and this serves as an important indicator of the stress effect on cells. In addition, in such bees, the activity of genes involved in navigation and memory is reduced.

The biologists also conducted field studies in the Chilean province of Linares, comparing populations of bees living near power lines and away from them. Again, it turned out that in the presence of intense electromagnetic fields, the synthesis of heat shock proteins in insects was much higher. In addition, bees visited Eschscholzia californica flowers growing near power lines three times less often than the same plants located far from electrically conductive lines.

The authors noted that the negative effects of anthropogenic electromagnetic fields on bees are unlikely to completely disappear. Today, their sources are not only high-voltage power lines, but also cellular base stations, as well as ordinary smartphones during active data transfer. So in reality, insects are often exposed to a whole set of artificial fields at the same time, which can enhance their impact.
