As much of the country faces freezing temperatures, auto experts are challenging long-held beliefs about winter driving routines. The latest advice from AAA suggests that drivers should only idle their engines for the brief moment it takes to fasten seat belts. This practice ensures lubricating oil reaches critical engine components without causing unnecessary wear or contributing to air pollution. Modern vehicles, equipped with advanced technology, do not require prolonged idling. However, older cars and electric vehicles may still need special attention before hitting the road in cold weather.
The tradition of warming up cars before driving dates back decades when vehicles were more prone to stalling in cold temperatures. Up until the 1980s, cars relied on carburetors, which needed time to achieve the right air-fuel mixture. Today's vehicles use electronic fuel injection systems, allowing them to be ready to drive almost instantly, even in frigid conditions. Despite this technological advancement, old habits die hard, and many people continue to idle their cars unnecessarily.
For electric vehicle (EV) owners, the situation is slightly different. While most internal combustion engines don't require a warm-up period, EVs perform optimally at around 70 degrees Fahrenheit. Cold temperatures can reduce battery efficiency, leading to a 10% to 20% drop in range. To combat this, EV owners are advised to precondition their vehicles using smartphone apps, heating both the battery and interior while the car is still plugged in. This process ensures the vehicle is fully charged and ready for optimal performance. For those without preconditioning features, warming the vehicle for a few minutes before driving can also help improve battery performance.
In conclusion, modern vehicles have evolved significantly, making traditional winter warm-up routines largely unnecessary. Drivers can now start their journeys immediately after starting their engines, reducing both environmental impact and engine wear. Electric vehicle owners, however, may benefit from taking extra steps to ensure their vehicles are prepared for colder conditions. By embracing these new practices, drivers can enjoy safer, more efficient winter travel.
