This is an endurance KART event in Brazil that many of the top name F1, CART and other drivers participate in. Interesting to note that Alex Zanardi competed and finished 4th.
Also interesting is that teamed with Barichello and Massa (both F1 drivers for Ferrari) was Marco Andretti -- Mario's grandson. Maybe he will be driving a Ferrari some day? Now that would be something to see. An American of Italian heritage in a Ferrari.
