If new numbers from Tesla Motors are any indication, consumers are growing increasingly interested in battery-operated cars.

The electric car maker, which last week unveiled a prototype of the Model X, said it racked up $40 million in reservations for the new all-electric crossover vehicle in just one day. As a result, the company has dubbed the Model X, its third vehicle, the "fastest selling Tesla ever."

"On Thursday evening, the night of the reveal, traffic to teslamotors.com increased 2800 percent," the car maker said in a statement. "Two-thirds of all visitors were new to the website."

Model X, described as a blending of SUV and minivan, will be priced in the $55,000 to $75,000 range. It features unique, so-called "falcon wing" rear doors, three rows of seats, and a new dual-motor, all-wheel drive system. It will likely enter production in late 2013, with deliveries beginning the following year.

Following the Model X unveiling, reservations for Tesla's Model S, an all-electric sedan that is expected to arrive in showrooms by July 2012, were up 30 percent, the company said.

Meanwhile, Tesla on Wednesday released its fourth quarter financial results. The company reported a net loss of $81.5 million and a $254.4 million loss for the full year.

However, the company's revenues during the fourth quarter totaled $39.4 million, up from the $36.3 million during the same period last year. And its revenue for the full year totaled $204.2 million, up from $116.7 million a year earlier.
