Ford, Nissan, and GM announced new moves into the world of electric vehicles, creating further competition for Elon Musk’s Tesla. CNBC reports that Tesla shares fell by 3.7 percent this week as auto manufacturers across the world revealed a new interest in electric car manufacturing. Ford chairman Bill Ford stated that the company plans to invest $11 billion in electric vehicles by 2022, hoping to add 40 different hybrid and electric vehicles to their current vehicle lineup. Ford CEO Jim Hackett discussed this with CNBC’s Phil LeBeau at the Detroit auto show on Sunday, saying: “We talked about a huge investment in electric vehicles. We have 16 models that are in design and development. We have a pretty big surprise coming next year.” Similarly, the CEO of General Motors, Mary Barra, told investors before the auto show that the company was working on a fully electric version of their popular Cadillac car, which is reportedly expected to be an SUV model. Nissan revealed that all future models from their “Infiniti” luxury brand will be “electrified,” meaning that they will either be entirely electric or a plug-in hybrid model. At CES in Las Vegas last week, Nissan also debuted their new electric car called the “Leaf Plus” which is set to be available for purchase in early spring and will drive approximately 226 miles per charge of its lithium-ion battery. Over the course of the Detroit auto show, Ford shares rose by 1.9 percent while GM’s rose 1.3 percent, Nissan faced technical difficulties when debuting one of their new cars on stage – their share price remained flat. Tesla recently announced that the company will no longer be taking orders for the popular 75 kWh battery version of their Model S and Model X vehicles, with the 100 kWh battery version becoming the standard model. At the same time, CEO Elon Musk promised that future models of their Roadster vehicle would be able to literally fly.
