McLaren 570S Carbon Fiber Body
McLaren is one of very few carmakers using carbon fiber to make the entire cabin. But eventually this will become quite normal, because carbon fiber isn't expensive — but molding it has proved costly because it's traditionally required a lot of labor. The MonoCell II chassis of the 570S is made differently; rather than doing a hand-molding process that might take days per car, McLaren uses a system that molds all of the shapes of the cell in three dimensions and can make the entire cell in a few hours. With the 570s, the resulting chassis is incredibly lightweight — just 176 pounds for the entire cabin. While the McLaren 570S uses aluminum body panels, it's likely the British carmaker (and rivals) will soon switch to carbon for the exterior as well. That will yield incredible fuel savings. As it is, we're talking about a car with a 562hp turbocharged V-8 and a top speed of 204 mph that gets 25.5 combined mpg (EU; US EPA is pending). Just imagine what an all-carbon fiber econobox might average.
