Tesla unveils Model X electric car with Falcon Wing doors

Silicon Valley electric car-maker Tesla has launched its third model to date - a sports-utility vehicle distinguished by its double-hinged "falcon wing" rear doors, which unfurl themselves upwards to help parents put their children inside.

The Model X was unveiled nearly two years later than originally scheduled.

The firm's chief executive Elon Musk acknowledged that the "difficulty in engineering" some of the parts involved had been greater than he had originally expected.

The car can fit seven people and can travel about 250 miles (400km) on a single charge.

However, analysts say its price - which runs as high as $144,000 (£95,100) - is expected to temper demand. Tesla has said it plans to unveil a lower-cost vehicle in 2017.

The company has yet to make a profit.
