The exact range can vary depending on driving conditions, driving behavior, and weather conditions, but according to the manufacturer, the Tesla Model S Long Range has an estimated range of approximately 652 kilometers (WLTP cycle).

It is important to note that the range of an electric car depends on several factors, including the battery pack, the car's energy consumption, driving conditions, and speed. Other electric cars that also offer a significant range, albeit slightly lower than the Tesla Model S, include:

However, it is important to note that the technology and performance of electric cars are constantly evolving and new models may be released with improved ranges. It is advisable to consult the specifications and range of specific models with the manufacturer or an authorized dealer, as this information may vary depending on the model year and configuration of the car.
