Will Power led the only IndyCar Road America practice of the weekend Saturday, shooting to the top of the chart on his 22nd and final lap of the session at 1 minute, 46.0021 seconds in his No. 12 Dallara-Chevrolet.
Dixon knocked Jack Harvey’s No. 60 Dallara-Honda from the top spot (which would have marked the first time that a Meyer-Shank Racing car led practice).
Josef Newgarden, Power’s Team Penske teammate, was third, followed by Felix Rosenqvist and Ryan Hunter-Reay (who went off course late in the session but sustained no damage).
Alex Palou, Colton Herta, Graham Rahal, defending race winner Alexander Rossi and Pato O’Ward rounded out the top 10 in the practice that preceded a Saturday-Sunday race weekend doubleheader for IndyCar at Road America.

RATED ROOKIE: Rinus VeeKay rebounding well from a tough debut
IndyCar tested some new cooling devices with cars from Andretti Autosport, Chip Ganassi Racing and Team Penske. Several drivers have said the cockpit heat caused by the new aeroscreen was stifling during last week’s GMR Grand Prix, and IndyCar repositioned drink bottles this weekend to keep liquids cool. The pieces tried by IndyCar during the Road America practice won’t be available during the races Saturday and Sunday at the Elkhart Lake, Wisconsin, road course.
Scott Dixon, who is seeking to open the season with his third consecutive IndyCar victory, was 15th fastest in the 75-minute session. Other notables in Road America practice: Marco Andretti (12th), Simon Pagenaud (19th).
Power is aiming for his second consecutive pole position after qualifying first last week on the Indianapolis Motor Speedway road course.
Qualifying for the REV Group Grand Prix Race #1 will take place at 2:15 p.m. ET (NBCSN, NBC Sports Gold).
The broadcast of the IndyCar race at Road America will begin at 5 p.m. on NBCSN.
