The battery is produced in Chattanooga and tested locally, which has the advantage of providing test feedback directly to the production plant. < / P > < p > now Volkswagen is making all the battery packs for American models in Georgia and assembling them in Tennessee. One of the main concerns of battery testing is to squeeze out as much range as possible. < / P > < p > the driving range is the key factor that makes electric vehicles stand out among many competitors today, and buyers will ask for as much mileage as possible. The challenge for Volkswagen is to maximize battery mileage while maintaining reliability. To squeeze out all the possible range from ID. 4, Volkswagen is looking at the system as a whole, not just the battery itself. < / P > < p > it is understood that most electric vehicles use specialized tires to create less rolling resistance and thus make the vehicle more efficient.
