A heated windscreen ensures a clear view in the colder months and saves you the hassle of scraping ice. Nevertheless, it is rather rare. In this article, we reveal why this is the case and why even cars in the higher price segment don’t offer this luxury.
Heated windscreens: rarity and technical hurdles explained
Formerly, Ford was the only manufacturer to offer heated windscreens in almost all of its vehicles. This technology was first introduced by Ford in 1985 in the Scorpio model.
- Ford long held the worldwide patent for windows with heating wires. However, this expired in 2019 after being extended several times Until 2019 only vehicles from the Ford Group were allowed to be equipped with this technology. This has led to other car manufacturers developing alternative solutions, such as transparent heating elements.
- The heating wires in the windshields are made of tungsten and are divided into two separate heating fields, which increases the efficiency of the heating system and ensures more even heat distribution;
- One of the reasons why heated windscreens have not caught on is that the fine heating wires are often perceived as a nuisance. They are visible and impair the clear field of vision, which many drivers found unpleasant.
- Another problem was the interference with cell phone reception and the satellite connection of navigation systems for vehicles. The heating wires could interfere with these signals, which often meant that external aerials had to be fitted.
- In countries with toll systems, where charges are billed by radio, there were also problems. The wires in the windshield hindered communication between the vehicle and the toll station, which led to malfunctions.
- The costs and energy consumption are another reason why heated windscreens have not really caught on.
Modern alternatives to heated windscreens: efficient solutions for a clear view in winter
Many modern vehicles, such as Volkswagen, use alternative systems that do not require visible heating wires.
- So transparent heating elements are an increasingly popular solution that offer the benefits of heating without the visual disadvantages of wires. These systems work more efficiently and require less energy.
- Another trend is the integration of parking heaters, which can also heat the windshield. In conjunction with powerful blowers, the need for a heated windshield is reduced in many vehicles, as these additional heating methods provide sufficient heat to quickly clear frost or ice.
- Air circulation and air filters have also proven helpful in preventing windows from fogging up. In conjunction with modern air conditioning systems and dehumidifiers, they offer an alternative solution that can eliminate the need for manual ice scraping.
