to get some paper and pens. As von Holzhausen began sketching the outside of the Model S, the Tesla engineers had started up a project to build another electric CLS. They ripped this one down to its very core, removing all of the body structure and then stretching the wheelbase by four inches to match up with some of the early Model S specifications. Things began moving fast for everyone involved in the Model S project. In the span of about three months, von Holzhausen had designed 95 percent of what people see today with the Model S, and the engineers had started building a prototype exterior around the skeleton. Throughout this process, von Holzhausen and Musk talked every day. Their desks were close, and the men had a natural rapport. Musk said he wanted an aesthetic that borrowed from Aston Martin and Porsche and some specific functions. He insisted, for example, that the car seat seven people. “It was like ‘Holy shit, how do we pull this off in a sedan?’” von Holzhausen said. “But I understood. He had five kids and wanted something that could be thought of as a family vehicle, and he knew other people would have this issue.” Musk wanted to make another statement with a huge touchscreen. This was years before the iPad would be released. The touch-screens that people ran into now and again at airports or shopping kiosks were for the most part terrible. But to Musk, the iPhone and all of its touch functions made it obvious that this type of technology would soon become commonplace. He would make a giant iPhone and have it handle most of the car’s functions. To find the right size for the screen, Musk and von Holzhausen would sit in the skeleton car and hold up laptops of different sizes, placing them horizontally and vertically to see what looked best. They settled on a seventeen-inch screen in a vertical position. Drivers would tap on this screen for every task except for opening the glove box and turning on the emergency lights—jobs required by law to be performed with physical buttons. Since the battery pack at the base of the car would weigh so much, Musk, the designers, and the engineers were always looking for ways to reduce the Model S’s weight in other spots. Musk opted to solve a big chunk of this problem by making the body of the Model S out of lightweight aluminum instead of steel. “The non-battery-pack portion of the car has to be lighter than comparable gasoline cars, and making it all aluminum became the obvious decision,” Musk said. “The fundamental problem was that if we didn’t make it out of aluminum the car wasn’t going to be any good.” Musk’s word choice there—“obvious decision”—goes a long way toward explaining how he operates. Yes, the car needed to be light, and, yes, aluminum would be an option for making that happen. But at the time, car manufacturers in North America had almost no experience producing aluminum body panels. Aluminum tends to tear when worked by large presses. It also develops lines that look like stretch marks on skin and make it difficult to lay down smooth coats of paint. “In Europe, you had some Jaguars and one Audi that were made of aluminum, but it was less than five percent of the market,” Musk said. “In North America, there was nothing. It’s only recently that the Ford F-150 has arrived as mostly aluminum. Before that, we were the only one.” Inside of Tesla, attempts were repeatedly made to talk Musk out of the aluminum body, but he would not budge, seeing it as the only rational choice. It would be up to the Tesla team to figure out how to make the aluminum manufacturing happen. “We knew it could be done,” Musk said. “It was a question of how hard it would be and how long it would take us to sort it out.” Just about all of the major design choices with the Model S came with similar challenges. “When we first talked about the touch-screen, the guys came back and said, ‘There’s nothing like that in the automotive supply chain,’” Musk said. “I said, ‘I know. That’s because it’s never been put in a
