Andretti again tops Iowa IndyCar practice session 2

Make no mistake about it, Marco Andretti loves the Iowa oval. He won this race last year and so far today he's been unbeatable. They unloaded his Andretti Autosport Chevy and it has been fast right from the start.

After leading the opening practice session this morning, Andretti topped 186 mph after only his 8th lap in practice 2 and no one was able to touch him the remainder of the session.

Dario Franchitti (Honda) came closest, on his last lap he turned a 185.715 mph lap, 0.03s behind Andretti.

Except for Franchitti's Honda, Chevy dominated the top-7 in this session.

Up next are the heat races at 7:15 ET.
