Jack Hawksworth makes IndyCar test debut with Rahal Letterman team

The Briton spent Tuesday at Sebring with Rahal Letterman Lanigan, and said that the experience was productive and eye-opening in equal measure.

"It was a lot of fun, and I think we had a really strong day as well," he said.

"What was really cool about it was that we actually went into a test plan. We were testing things, we weren't just going out and doing laps, you were working with an IndyCar team on a test day and trying to develop the car and things that they want to test. I really enjoyed that part of it.

"The big thing is for me that the braking is different. In the Lights car you can't hit the brake nearly as hard as you can hit it in an IndyCar.

"But the way you actually drive the car in terms of how you went into the corner, how you try to get your turning done in the corner is quite similar."

Hawksworth, who came into the test off the back of a dominant win in Baltimore two weeks ago, is one of four drivers covered by just 11 points at the top of the Lights championship standings with two weekends remaining.
