Tesla CEO Elon Musk recently revealed through a Twitter response that Tesla had the ability to build a Model S with a range of more than 600 miles (about 965 kilometers) as early as 1 year ago. But he said, "That makes the product experience worse."
Musk points out that increasing range essentially requires higher battery capacity, which would mean larger, heavier, and more expensive battery packs. This kind of battery is "unnecessary" in daily use. He said the current Tesla model has more than enough range of just over 400 miles (about 644 kilometers). If you use a larger battery in pursuit of endurance, the vehicle's handling and energy efficiency performance will be greatly affected.
In fact, under the same battery technology, large battery capacity brings high endurance, heavier weight and larger volume, which will indeed affect the energy efficiency and even handling performance of the vehicle. For example, the Audi e-tron Sportback's 50 quattro and 55 quattro, although the power difference between 313 horsepower and 408 horsepower, the 55 quattro (2,599 kg) is also more than 100 kg more than the 50 quattro model (2,455 kg).
The reason why Elon Musk said that Tesla did not pursue the ultimate endurance in the mass sale car is also because the battery is not so large can bring lighter weight and lower car price; but the price is that it needs to be recharged frequently. At present, Musk's idea is that making electric vehicles affordable for more people will be a better route for industrial development. Tesla and other car manufacturers have also continued to strengthen fast charging networks to popularize electric vehicles.
