Usain Bolt gets an all-gold Nissan GT-R and a new title

Now that's a publicity stunt. In recent a day-long event, Nissan hosted

Olympic gold medallist Usain Bolt--the company's new "Director of Excitement"--at its offices in Yokohama, Japan, where the sprinter unveiled a

custom-edition of the $100,000 GT-R, with interior bits coated in real

gold. Nissan says that GT-R will be auctioned for Bolt's charity

foundation, but that it will also build a special 545-hp GT-R for Bolt's

personal use, customized based on his own reaction times.
