The Tesla Model 3, unveiled in July, is expected to be the most affordable car ever built.
But one of its biggest selling points is its battery, which can charge the Model 3 in just 30 minutes on a single charge.
In the past, it’s been the subject of debate whether the battery’s energy density is enough to charge a car, but now Tesla is offering up a new study that suggests the batteries are as good as ever.
“We are very confident that the battery will provide long-term reliability,” Elon Musk, the company’s chief executive, told reporters in New York on Tuesday.
Musk said the battery pack’s energy densities were 10 times greater than the previous generation’s, and the range was extended to 250 miles, which was the maximum range on any battery pack ever built, according to Bloomberg.
That means that Tesla can have the most energy density in its entire lineup of electric vehicles and still deliver long-range performance, Musk said.
Tesla said it was working with the battery manufacturer Panasonic to increase the battery capacity and also reduce the weight of the vehicle, while keeping the overall design of the Model S. Tesla also unveiled a number of other new models at the New York event, including the Model X SUV and Model 3 sedan, which are expected to come in 2018.
Ahead of the New Year, the Tesla Model S sedan has sold more than 10 million units since its release in June 2016.
In June, Tesla launched its Model X crossover SUV.
