With the innovation of electric cars, scientists are concerned with ozone emission from electrically charged vehicles. However, the four-wheelers operated by fossils also come in contact with ozone.

According to some studies, Tesla cars generate two folds more ozone than ordinary fuel-operated vehicles. The ozone production in Tesla is proportional to the variants of twists.

Whatever the cause, ozone has the worst impact on our health and our vehicle as well. It attacks the respiratory system, thus making it difficult to breathe.

The ozone in the air ducts of your auto will cater to your olfactory ducts with a rotten egg-like smell. This rotten-egg-like stench may resemble the vinegary smell.

Modern vehicles have air conditioners for the cause of temperature regulation in the car space. Whereas primitive automobiles had a simple manual air conditioner. People used it to direct the winds to an angle as set by the driver. If unfortunately, the microorganism gets the chance to breed in this tiny component, it would again cause a terrible odor. The pathogens undergo biochemical changes, and that leads to the car stinking like mildew.

Even the air conditioner is not out of the league, rather, they also serve the toxic agents. The bacteria can also grow inside the air conditioners of present-day cars. That again results in the smelly air conditioner car.

So if these devices come in contact with something boiling, then a driver or passenger whiffs a burning smell. As rubber is a frail material, a mere threshold of heat causes the car to stink. Sometimes the rubber-burning smell might arise from a fuel gush or a tatty seatbelt. Besides the rubber burning, there could be the chances of stenches effusing out as electrical burns. When you breathe in a burning stench arising from an electrical route, probe your air conditioner compressor. The compressor might be hyper-thermic.
