INDYCAR has announced an update for the aerodynamic specifications to be used in Sunday’s 400-miler at Pocono Raceway in Pennsylvania.
Through an update of Rule 188.8.131.52 of the IZOD IndyCar Series rulebook, the underwing strake has been added to the list of optional parts that can be used on the Pocono spec to create more downforce. This comes after a collection of feedback from drivers, engineers and teams on various configurations used during testing.
The optional parts also include a side wall, trimmed side wall, rear wheel backing plate, sidepod top infill, 2/3 radiator inlet shutter, and rear wing wicker. Mandatory parts include a rear mainplate between zero and negative 10.5 degrees, a rear mainplate profile and the rear wheel guard used at the Indianapolis 500.
Eight IndyCar squads tested last week at Pocono, and the series will stage an Open Test there on Thursday in advance of Sunday’s race.
Newgarden fastest as Castroneves returns in weather-shortened Barber test
The Verizon IndyCar Series took to Barber Motorsports Park on Tuesday for an open test, with 24 entries tackling the 2.38-mile road course.
Weather intervened in the afternoon, preventing nearly the entire field from going out, but the weather held off during the morning enough for one session to be run in its entirety.
Team Penske’s Josef Newgarden led the way, with a quick lap of 1:07.979, ahead of Team Penske teammates Will Power and Helio Castroneves. For Castroneves, this marked his first IndyCar outing of 2018.
Sporting the Pennzoil “yellow submarine” paint scheme, Castroneves turned 41 laps around Barber in the morning session, with a quick lap of 1:08.315. He was also the only driver to venture out on track in the afternoon, completing eight laps.
The Dale Coyne Racing duo of Sebastien Bourdais and Zachary Claman De Melo completed the top five.
