The only drawback, he admitted, was that it would be even more expensive than current Tesla models, which regularly go for over $100,000 (and that’s even with government tax incentives).
The current Tesla Model S has an EPA-rated range of 265 miles per charge, far more than competing electric vehicles. According to Musk, that range is produced via a combination of superior aerodynamics and the most powerful battery on the market.
As he explained to AutoExpress,
“We have the highest energy density battery in the world, twice that of the Nissan Leaf. But our range is more than twice that of the Leaf, so we come into other factors: what’s the drag co-efficient of the car, how much does it weigh, what’s the efficiency of the motor and gearbox, what’s the rolling resistance? All those factors affect the range.”
When asked how far EVs will be able to go, Musk responded that a 500-mile battery would be easy to achieve but not so easy to purchase.
Tesla is in no hurry to push an even more expensive model to market. After all, this is the company that freed all their patents just to foster more electric competition. Plus, current studies show that 500 miles – even 200 miles – is far more than most people drive in a day. Gas2 states that 95 percent of driving trips run under 50 miles per day.
All that said, Global Equities Research recently revealed that Tesla has filed patents for a hybrid battery pack that would boost mileage to 400 miles per charge. The pack would be composed of half lithium-ion and half metal-air batteries, with the metal-air batteries to be used as a reserve in the case of extended journeys.
