Lynn positive after first test in a Cadillac DPi-V.R

The 23-year-old Briton, who had never previously driven on an American racetrack, lapped the full-length Sebring course in 1m51.013s, an average of 121.2mph, in the car that won the Rolex 24 Hours at Daytona last month.

That time put him sixth fastest, 1.254s off the #5 Action Express Cadillac piloted by Filipe Albuquerque, and less than a second slower than one of his teammates for the Sebring 12 Hours, Jordan Taylor.

Meanwhile his other new teammate, Ricky Taylor, was testing a Penske-Chevrolet IndyCar at Homestead-Miami road course.

“There were a lot of new things for me to learn today,” Lynn said. “I think we had a really positive day.

“I’ve learned a lot from the engineering team and also Jordan. He’s obviously been a really great teammate for me today. We were going through a lot of stuff and trying to put in some good lap times.” 

Lynn, who was 2014 GP3 champion and has five GP2 wins to his credit, said he believes the new-for-2017 DPi cars allowed for an easier transition for drivers used to open-wheel racing.

“I think this new generation of Prototype in IMSA, relates quite nicely, because they’re obviously really powerful cars with high downforce,” Lynn said.

“It’s more coming into that trend of a real open-wheel spec kind of car or even an LMP1-type car. I feel like my experience there has helped me.”
