Formula One champ Lewis Hamilton will take the wheel of Tony Stewart's #14 NASCAR Sprint Cup Chevrolet at Watkins Glen. For lending Hamilton his car, Stewart will get the opportunity to try out the 2010 McLaren MP4-25. While both men are likely to come away shaky in the knees and with a better understanding of each other's racing worlds (as did Jeff Gordon and Juan Pablo Montoya when an earlier swap was arranged) this isn't just two random pals tossing their respective keys to each other.
Components from F1 cars – especially championship-winning F1 cars – don't go to waste. Collectors eagerly snap them up and put them on display as fast as the teams will release them. But in this case, the motor oil from Lewis Hamilton's title-winning McLaren-Mercedes MP4-24 was used to create a tribute to the driver.
