The Mazda Road to Indy Presented by Cooper Tires Spring Training Open Test concluded this afternoon at Homestead-Miami Speedway with 15 Indy Lights drivers strutting their stuff in preparation for next week’s season-opening races some 200 miles or so to the northwest on the Streets of St. Petersburg, Fla. 

A total of 1271 laps were logged during the course of six and a half hours of testing. Rookie Colton Herta, the youngest driver in the field at just 16, emerged with early bragging rights after posting a fastest lap of 1:15.2009, an average speed of 105.797 mph around the 2.21-mile road course.

After completing one day of testing on the 1.5-mile oval on Monday, the teams spent the past couple of days converting their Dallara-Mazda IL-15s from oval to road course configuration. The drivers, meanwhile, were kept busy with presentations from Mazda and Cooper Tires, plus an overview of the expanding RoadToIndy.TV initiative and interviews with an NBCSN television crew in advance of the new season. 

Lap times remained close throughout the day, although Herta, from Valencia, Calif., was out of the blocks quickly. Herta, who began his professional career in the Cooper Tires USF2000 Championship Powered by Mazda in 2014, marked his return to racing in North America following two years in Europe by jumping to the top of the speed charts early for the new Andretti-Steinbrenner Racing combination. Herta’s time of 1:15.6405 remained fastest for much of the morning session before series veteran Kyle Kaiser (Juncos Racing) overcame some braking inconsistencies to edge him with a best of 1:15.5603.

Santi Urrutia, from Miguelete, Uruguay, who won the 2015 Pro Mazda Championship Presented by Cooper Tires and finished an agonizingly close second in last year’s Indy Lights title-chase, ended up third on the charts, narrowly ahead of fellow Belardi Auto Racing representatives Aaron Telitz, who succeeded Urrutia as Pro Mazda champion in 2016, and Shelby Blackstock.

All 15 drivers were separated by just 1.0868 second during the morning session. 

Herta, the son of 1993 Indy Lights champion and two-time Indianapolis 500-winning car owner Bryan Herta, again was out of the blocks quickly following the lunch break. He improved his time with less than an hour remaining to what would stand as the fastest of the day, almost 0.3 second clear of a gaggle of cars headed by Andretti Autosport stablemate Nico Jamin, the 2015 USF2000 champion, who turned a best lap of 1:15.5004. 

Kaiser, Urrutia and Colombian Juan Piedrahita (Team Pelfrey) all circulated within one-tenth of Jamin’s time, with Brazilian rookie Matheus Leist (Carlin), last year’s BRDC British F3 Champion, Mexico’s Pato O’Ward (Team Pelfrey), Telitz, Blackstock and Argentina’s Nicolas Dapero (Juncos Racing) all blanketed by another one-tenth of a second.
