GT3 Cup Challenge USA Barber Motorsports Park Friday Notebook
Friday, April 21, 2017

The Porsche GT3 Cup Challenge USA by Yokohama scored their first official laps today in the series’ debut at Barber Motorsports Park in Birmingham, Ala. As the official home of the Porsche Sport Driving School, the 2.38-mile, 17-turn picturesque circuit is a fitting backdrop to host the ultra-competitive series.

Wasting no time getting up to speed, the Platinum Cup class – comprised of new 2017 model Porsche 911 GT3 Cup cars – was led by Will Hardeman in the No. 19 Moorespeed/Continental Automotive Group entry. His time of 1 minute, 27.326 seconds will set the benchmark for tomorrow’s qualifying round.

Both Hardeman and his team hail from Austin, Texas, home of Circuit of The Americas, the next stop on the GT3 Cup Challenge USA calendar.

In Gold Cup, Roman De Angelis posted a 1:29.137 lap in his Mark Motors Racing No. 78 to lead the field of 2014-2016 model GT3 Cup cars. He swept the first two rounds of series competition at Sebring International Raceway in March and his Toronto-based team will be looking for a repeat performance throughout qualifying and two rounds of racing this weekend. The team regularly competes in the Porsche GT3 Cup Challenge Canada series as well.

Platinum Masters driver Jeff Mosing set the quick time of the day for his class with a 1:28.930 lap in his No. 01 TOPP Racing/Mosing Motorcars GT3 Cup car. Experienced drivers 45 years of age compete for class and overall honors in the Masters category.
