Mercedes-Benz has introduced a huge wheeled air purifier. Electric van Sustaineer showcases a set of green technologies

Published

on

Mercedes-Benz has unveiled the Sustaineer concept car. The car itself is not particularly interesting here, as it is a regular electric van eSprinter.

Conceptuality is different. The bottom line is that the Sustaineer is actually a huge, portable air purifier. There is a fine filter in the front and on the bottom, a solar panel on the roof, components made from recycled materials, and a heating system located next to the body.

Air quality is a key factor in the quality of life in urban areas. Along with CO emissions2 road traffic also causes significant particulate pollution. The Sustaineer has a number of new features designed to further minimize the formation of particles caused by tire, brake and asphalt wear. These include two fine filters developed in collaboration with filtration specialists MANN + HUMMEL, low-emission, low-wear cast iron brake discs and tires optimized for rolling resistance and therefore low noise and wear.

The underbody fine filter is located in the rear axle area. This is where one of the highest concentrations of particulate matter can be found in the immediate vicinity of a vehicle. The passive filter traps particles picked up by a moving van and other vehicles. The optimized air duct system provides the best cleaning effect. The filter must be replaced once a year.

A second filter is integrated in the front module and works in conjunction with an existing exhaust fan to filter air from small particles. This means that it not only purifies the air using the airflow around the vehicle while driving, but also filters out particulate matter from the surrounding air when the vehicle is moving at low speed or charging while stationary. Additionally, the vehicle is equipped with a fine particle sensor. This allows the concentration of small particles in the air to be measured and the filtration level adjusted accordingly to maintain a given condition. It also allows the vehicle to be used as a mobile monitoring station. The filter elements are easily removed and replaced with annual service.

The front module and under-body filters reduce emissions of fine particulate matter in the immediate vicinity of the vehicle to a size of ten micrometers (PM10) by more than 35-50% while charging and 15% while driving. The efficiency of the filtration system is improved even more with higher levels of particulate contamination. This means that much more fine particles can be filtered in urban areas with lower air quality.

In addition, Sustaineer offers other green technologies. There are a lot of recycled parts, an energy-efficient heating system (for example, a heated seat belt), a silent automatic side door, and so on.

The German auto giant did not say anything about the plans for the production of such cars, but noted that the concept was created with the expectation of large-scale production.

Weight 15 kg, 25 km / h, soft suspension and load capacity 100 kg, inexpensive. Yadea KS3 Electric Scooter Introduced

Published

on

Electric vehicle manufacturer Yadea has released the convenient, lightweight and inexpensive Yadea KS3 electric scooter, which is a smaller version of the more expensive, powerful and heavier Yadea scooters.

It is designed for drivers who need to carry it frequently by hand when reaching their destination. Therefore, they do not need to worry about the scooter being stolen in the parking lot. This foldable scooter weighs just under 15 kg and has a payload of 100 kg. It can reach a top speed of 25 km / h and has a 500 W motor.

The KS3 competes favorably with electric scooters in its price range. It boasts some additional features that will draw extra attention to it. The Yadea KS3 has a soft front suspension that helps smooth bumps. The 8.5 x 2.4 inch tires do not need to be inflated. The minimum wear resistance of the tires is about 5,000 km. With a declared range of 30 km without recharging, tires can last for several years and more than 150 full charge cycles.

The front drum brake is also an innovative feature of the KS3. The drum brake is maintenance-free and sealed to better protect it from dirt and damage. Brake drums will not fade in wet conditions. Likewise, the rear brake is durable and requires no maintenance. The rear brake charges the battery during braking on the road.

The Yadea KS3 is cheaper than its faster predecessors. The Yadea KS3 electric scooter costs $ 569 and can be purchased on Amazon.

Elon Musk continues to sell Tesla shares. How the course reacts

Published

on

Tesla founder Elon Musk sold more Tesla shares a week ago than he needed to pay his current tax liabilities. At that time, the amount was $ 8.8 billion, but he continues to sell shares in the company.

He sold another 934,091 shares this week for $ 1.05 billion. Since the beginning of this month, he has sold nearly $ 10 billion worth of shares in the company. Initially, he announced that he would sell 10% of the company’s shares, at that time they were valued at $ 21 billion. That is, he has now sold about half of the planned number of securities.

The sharp drop in Tesla shares happened after a poll in which Elon Musk asked readers if he should sell the company’s shares. Then the rate fell from 1200 to 1000 dollars, but then there was an adjustment, and now the companies give about 116 dollars per share.

Eric Gordon, a professor of business and law at the University of Michigan, previously suggested that Musk expects the stock price to fall: “If you think the stock will rise or stay at its current level, you will not sell additional shares.”

Skoda has officially announced the first details about the Skoda Afriq sports crossover, which is being created by 25 vocational school students in cooperation with Skoda Motorsport.

This is the rally version of the Skoda Kamiq city SUV, which is dedicated to the legendary Dakar Rally in Africa. The name Skoda Afriq was also chosen for another reason: Since the beginning of this year, Skoda has been in charge of all Volkswagen Group activities in North Africa.

The letter “Q” at the end of the car’s name indicates its belonging to the Skoda crossover family – by analogy with the Kodiaq, Karoq, Kamiq and Enyaq models. It has already been determined that the Skoda Afriq has a length of 4362 millimeters and a wheelbase of 2649 millimeters.

What kind of improvements Skoda Afriq will receive in comparison with Skoda Kamiq has not yet been reported. The standard crossover Skoda Kamiq has been produced in Europe since 2019. In the maximum configuration, it has a 1.5-liter petrol engine with a capacity of 150 hp. with. with 250 Nm of torque.

Skoda has announced a sports crossover Afriq

At the 40th Desert Rally in 2018, the Kodiaq became the first Skoda ever to compete in what is arguably the world’s toughest rally. The large Skoda SUV was used as a support vehicle for the Czech Barth Racing team. The unmodified production model easily covered the nearly 10,000-kilometer route through Peru, Bolivia and Argentina – in some sections at an altitude of over 4,500 meters.
