National Geographic takes an exclusive look at how Lexus built its iconic LFA supercar. Having gone inside Gumpert and profiled the Nissan GT-R, in the latest episode of National Geographic's "Megafactories" series the focus is on the production of the Lexus LFA at the Motomachi plant in Japan. The 4.8-liter V10-powered supercar has become an icon in a short passing of time, and the final LFA rolled off the assembly line at the end of last year. We've seen Jay Leno visit the factory before hooning a one-off LFA Spyder around the Fuji Speedway. But this 45-minute video is the definitive look at how the LFA Works operates, with insight into each step of the process and a rare glimpse at the absolute dedication that went into building each of Lexus' 500 supercars.
