Famed race car drivers Al Unser Sr. and Al Unser Jr. participated in the Bosch press event in Las Vegas that culminated the year-long celebration of "100 Years of Sparking Innovation." The father-and-son drivers are shown with the Marmon Wasp, the actual car that won the very first Indianapolis 500 in 1911. A highlight of the press event was the opportunity for journalists to have their photograph taken actually sitting in this priceless piece of automotive history.
