Tesla Motors

Versão em português:
          A Tesla Motors é uma fabricante de carros elétricos e baterias, fundada em 2003, por engenheiros do Vale do Silício, entre os quais o sul-africano Elon Musk, que queriam provar que o carro elétrico poderia ser melhor que os carros movidos a gasolina. Os engenheiros da Tesla primeiro desenharam um sistema elétrico para um carro esportivo construído em torno de um motor de indução AC, patenteado em 1888 por Nikola Tesla, o inventor que inspirou o nome da empresa. Engenheiro elétrico e cientista, Nikola Tesla ao longo de sua vida desenvolveu mais de 700 patentes.
          Apesar de ser hoje estar intimamente associada ao bilionário Elon Musk, a Tesla não é uma criação dele. A empresa nasceu das mãos de Martin Eberhard e Marc Tarpenning, dois empreendedores que sonhavam em criar um modelo de carro elétrico esportivo. Mas logo em seus primeiros anos, Musk se tornou o principal investidor da companhia e tirou os fundadores do negócio. O nascimento da companhia é contado por Tim Higgins, repórter do The Wall Street Journal, no livro A aposta do século: A Tesla, Elon Musk e seus jogos de poder, que chega agora ao Brasil pela Editora Planeta. “A grande contribuição de Musk para a Tesla foi a sua habilidade de vender a visão da empresa não só para consumidores, mas, o que era mais importante, para os investidores”, diz Higgins, em entrevista a Época Negócios.
          O logo da empresa de Elon Musk tem um T estilizado. Em julho de 2006, a virtualmente desconhecida start-up Tesla Motors apresentou seu primeiro carro durante um evento no aeroporto de Santa Mônica, na Califórnia. A empresa não tinha dinheiro para desenhar um carro do zero. Com isso, ela partiu da estrutura de um Lotus Elise. Totalmente elétrico, o Tesla Roadster original oferecia 292 cv e 393 km de autonomia. Ele custava US$ 109.000, uma proposta ousada para uma empresa que nunca tinha construído nem um carro sequer. Mas os compradores confiaram na Tesla, contra todas as expectativas, e a primeira fornada de 100 carros foi vendida em menos de um mês.
          Em agosto de 2016, a Tesla adquire a fabricante de painéis solares SolarCity por US$ 2,6 bilhões, em um grande passo do bilionário Elon Musk para oferecer aos consumidores um negócio totalmente especializado em energia limpa.
          A queda no custo das baterias e os ganhos de escala com o aumento da produção propiciam o surgimento de modelos mais acessíveis. Depois de atingir o público endinheirado, a Tesla quer chegar ao mercado médio dos carros elétricos com o Model 3. Em julho de 2017, as primeiras unidades desse modelo começam a ser entregues. Ele custa, na versão mais barata, 35.000 dólares - os Tesla anteriores partiam do dobro desse valor. O Model 3 tem autonomia de 350 quilômetros. Ou seja: essa é a distância que o carro consegue percorrer com uma carga de bateria.
          No início de novembro de 2017, a Tesla acumulava uma lista de quase 500.000 interessados no novo carro elétrico. Para atender a toda essa demanda, a companhia construiu uma enorme fábrica de baterias no deserto do estado de Nevada nos Estados Unidos para abastecer seus carros.

English version:
          Tesla Motors was founded in 2003 by a group of engineers in Silicon Valley who wanted to prove that electric cars could be better than gasoline-powered cars. With instant torque, incredible power, and zero emissions, Tesla’s products would be cars without compromise. Each new generation would be increasingly affordable, helping the company work towards its mission: to accelerate the world’s transition to sustainable transport.
          Tesla’s engineers first designed a powertrain for a sports car built around an AC induction motor, patented in 1888 by Nikola Tesla, the inventor who inspired the company’s name. The resulting Tesla Roadster was launched in 2008. Accelerating from 0 to 60 mph in 3.7 seconds and achieving a range of 245 miles (393 km) per charge of its lithium ion battery, the Roadster set a new standard for electric mobility. Tesla would sell more than 2,400 Roadsters, now on the road in more than 30 countries.
          Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success—unlike his early employer and chief rival, Thomas Edison.
          Nikola Tesla was born in 1856 in Smiljan, Croatia, then part of the Austro-Hungarian Empire. His father was a priest in the Serbian Orthodox church and his mother managed the family’s farm. In 1863 Tesla’s brother Daniel was killed in a riding accident. The shock of the loss unsettled the 7-year-old Tesla, who reported seeing visions—the first signs of his lifelong mental illnesses.
          During the 1890s Mark Twain struck up a friendship with inventor Nikola Tesla. Twain often visited him in his lab, where in 1894 Tesla photographed the great Anerican writer in one of the first pictures ever lit by phosphorescent light.
          Tesla studied math and physics at the Technical University of Graz (Austria) and philosophy at the University of Prague. In 1882, while on a walk, he came up with the idea for a brushless AC motor, making the first sketches of its rotating electromagnets in the sand of the path. Later that year he moved to Paris and got a job repairing direct current (DC) power plants with the Continental Edison Company. Two years later he immigrated to the United States. Tesla arrived in New York in 1884 and was hired as an engineer at Thomas Edison's Manhattan headquartes. He worked there for a year, impressing Edison with his diligence and ingenuity. At one point Edson told Tesla he would pay $50,000 for an improved design for his DC dynamos. After months of experimentation, Tesla presented a solution and askedfor the money. Edson demurred, saying, "Tesla, you don't understand our American humor." Tesla quit soon after.
          In 2012, Tesla Motors launched Model S, the world’s first premium electric sedan. Built from the ground up to be 100 percent electric, Model S has redefined the very concept of a four-door car. With room for seven passengers and more than 64 cubic feet of storage, Model S provides the comfort and utility of a family sedan while achieving the acceleration of a sports car: 0 to 60 mph in about five seconds. Its flat battery pack is integrated into the chassis and sits below the occupant cabin, lending the car a low center of gravity that enables outstanding road holding and handling while driving 265 miles per charge. Model S was named Motor Trend’s 2013 Car of the Year and achieved a 5-star safety rating from the U.S. National Highway Traffic Safety Administration.
          In late 2014, Tesla CEO Elon Musk unveiled two dual motor all-wheel drive configurations of Model S that further improve the vehicle’s handling and performance. The 85D features a high efficiency motor at the front and rear, giving the car unparalleled control of traction in all conditions. The P85D pairs a high efficiency front motor with a performance rear motor for supercar acceleration, achieving a 0 to 60 mph time of 3.2 seconds – the fastest four-door production car ever made.
          Now with more than 50,000 vehicles on the road worldwide, Tesla is preparing to launch Model X, a crossover vehicle that enters volume production in 2015. Featuring exhilarating acceleration, falcon wing doors, and room for three rows of seating, Model X defies categorization.
          Tesla owners enjoy the benefit of charging at home so they never have to visit a gas station or spend a cent on gasoline. For long distance journeys, Tesla’s Supercharger network provides convenient and free access to high speed charging, replenishing half a charge in as little as 20 minutes. Superchargers now connect popular routes in North America, Europe, and Asia Pacific.
          Tesla’s vehicles are produced at its factory in Fremont, California, previously home to New United Motor Manufacturing Inc., a joint venture between Toyota and General Motors. The Tesla Factory has returned thousands of jobs to the area and is capable of producing 1,000 cars a week.
          The company is expanding its manufacturing footprint into other areas, including in Tilburg, the Netherlands, where it has an assembly facility, and Lathrop, California, where it has a specialized production plant. To reduce the costs of lithium ion battery packs, Tesla and key strategic partners including Panasonic have begun construction of a gigafactory in Nevada that will facilitate the production of a mass-market affordable vehicle, Model 3. By 2020, the gigafactory will produce more lithium ion cells than all of the world’s combined output in 2013. The gigafactory will also produce battery packs intended for use in stationary storage, helping to improve robustness of the electrical grid, reduce energy costs for businesses and residences, and provide a backup supply of power.
          Tesla is not just an automaker, but also a technology and design company with a focus on energy innovation.
