Electric car brand Tesla claims to have set a new speed record for driving across the United States - and did so for free.
A pair of the company's Model S sedans travelled the 5575km from Los Angeles to New York in just over 76 hours.
The company is also trying to get the run verified by Guinness World Records for the least amount of charging time for an electric car crossing the country.
The trip was made possible by Tesla's own charging infrastructure, known as Superchargers, that the company claims can recharge the car's batteries to 80 per cent in 40 minutes.
Tesla has now opened 73 Superchargers across America which the company claims serves 80 per cent of the population. Each station contains four to 10 bays and are located primarily at hotels, restaurants and shopping centres.
Tesla owners are free to recharge at the Supercharger (except if you buy the entry-level Model S where it costs an extra US$2000) meaning owners never have to pay to recharge their car.
But the Supercharger network isn't without its problems at the moment. The claimed 20 per cent of the population not covered includes the majority of Oklahoma, Arkansas, Tennessee, Kentucky and Alabama, but Tesla says the network will be expanded to cover the majority of the country by 2015.
The path across America wasn't the most direct route either. The network currently snakes its way through Wyoming, South Dakota and Minnesota - at times doubling back on itself.
