LEBANON, Tenn.  No previous oval experience, no problem for Dennis Hauger.

Andretti Global rookie Hauger led the Indy NXT by Firestone Open Test on April 1 at Nashville Superspeedway on his first-ever day of driving on an oval, turning a top lap of 187.564 mph in the No. 28 Rental Group car. Hauger, from Norway, leads the standings in the IndyCar development series after winning the season opener March 2 on the streets of St. Petersburg, Fla.

First test on an oval, and it was a really cool experience, Hauger said. I had a lot of fun out there. Good day at the office, and Im looking forward to coming back here later in the season.
