Musk: Tesla Model S will reach nearly 644km

Elon Musk, chief executive of Electric car maker Tesla, said the model S was close to an electric car with a range of 400 miles (644 kilometers) as the Model S’s battery performance improved. So far, the Model S is the longest-lasting of Tesla’s many models. The U.S. Environmental Protection Agency (EPA) has a range of 373 miles.

However, Musk said that due to recent improvements, the U.S. Environmental Protection Agency (EPA) should actually estimate the mileage to be closer to 380 miles.

Musk said he expected the Model S to travel 400 miles (644 kilometers) on a single charge. He said model S was rapidly approaching 400 miles of range. So, before long, the Model S will have 400 miles of range.

Tesla has been investing in improving battery performance, hoping to get more efficient powersystems that will increase the battery life and range of electric vehicles.

For example, the company is building A Plaid Powertrain, a power train based on the new three-motor configuration, for model S and Model X. Musk said the system would be available by the end of the year.

Last year, Tesla’s job advertisement suggested that the company might produce its own batteries at its Gigafactory 4 in Berlin, Germany.

Media speculated through job advertisements that Tesla’s super factory in Berlin would not only produce cars and battery packs, but would also help develop and produce its own batteries.

Developing its own battery will allow Tesla to better control the price of its electric cars, making them cheaper for consumers.
