Bryan Herta Autosport, Sam Schmidt Motorsports, Vision Racing, and Andretti Green Racing are all spending the day at the historic Milwaukee Mile--testing for the upcoming race on May 31st. The lack of substantial banking and the high speed nature of the track should prove beneficial for the drivers developing their car control heading into the Freedom 100 next weekend at Indianapolis Motor Speedway--even though the two tracks and required driving style are very different from one another.
According to Bryan Herta's Tweets-- there are eight cars on track today. Without official confirmation I would have to assume that number means: Ana Beatriz, Wade Cunningham, James Davison, Daniel Herrington, J.R. Hildebrand, James Hinchcliffe, Sebastian Saavedra, and Gustavo Yacaman are all taking part in the test. I will try to post updates as they become available.
