Tesla Model 3 pre-orders stack up as Elon Musk unveils lower-priced car

Prototypes go on show in California in front of 800 fans as chief executive Elon Musk reveals 115,000 preorders ahead of 2017 launch

Tesla Motors has finally unveiled its long-anticipated lower cost electric car, the Model 3, at its design studio in Los Angeles.

Costing $35,000 and up, before government incentives, the Model 3 is less than half the cost of Tesla's previous Model S and Model X SUV and aimed at the mass market. The car car will go at least 215 miles (346km) on a full charge, which is around 85 miles less than the more expensive Model S, but about double what drivers of competitors cars costing similar, such as the Nissan Leaf and BMW i3.
