The Ultra 94 GT3 Cup Challenge Canada by Michelin heads to North America’s oldest street circuit this weekend when the series visits the famous Trois-Rivières circuit in Quebec.

The venue was first used in 1967 with the American Le Mans Series, the Grand-Am Rolex Sports Car Series, the Trans-Am Series, Can-Am, Indy Lights and Formula Atlantic also using the venue.

While the NASCAR Canadian Tire series is the modern headliner, Formula Atlantic was what put the Quebec menu on the map as a “star maker”.

Formula Atlantic Trois-Rivières winners in Atlantics have included Gilles Villeneuve, Price Cobb, Roberto Moreno, Michael Andretti, Patrick Carpentier, Alex Tagliani, Anthony Lazzaro, Buddy Rice, Michael Valiante, AJ Allmndinger, Simon de Silvestro and even Viper TUDOR United SportsCar Championship ace Jonathan Bomarito. Even Fox Sports commentator, Brian Till has a Formula Atlantic win to his credit.

In the Porsche ranks this weekend, the clock is ticking for every driver trying to chase Ultra 94 GT3 Cup Challenge Canada by Michelin Platinum Cup leader Scott Hargrove.

Two 45-minute races for the International Motor Sports Association (IMSA)-sanctioned series are scheduled on the 11-turn, 1.53-mile (2.46 km) Circuit Trois-Rivières,

Consistency has been a hallmark of Hargrove’s march toward the Platinum Cup (2014 model cars) championship. Hargrove, from Surrey, British Columbia, has led the points after all six rounds of this season in the No. 69 OpenRoad Racing Porsche. He has finished first or second in all six rounds, including four victories.

Chris Green, from Montreal, also is using consistency to keep Hargrove in sight. He has finished on the podium in five of the six rounds this season in the No. 9 Pfaff Motorsports 911 GT3 Cup car.

Spencer Pigot, from Orlando, Florida, kept his title hopes alive with his first win of the season July 20 in Toronto in the No. 21 Alegra Motorsports Porsche. He is third in the standings with 82 points.

Etienne Borgeat is among the Quebec-based drivers and teams in the spotlight this weekend.

It appeared Pigot might gain significant ground on Hargrove and Green during his victory in Toronto. Hargrove collided with Green on the first lap of the race, with Green’s car spinning and suffering damage and Hargrove forced to the pits to serve a penalty for the contact.

But Hargrove and Green both produced arguably their most inspired drives of the season to bob and weave through the field and salvage podium finishes, with Hargrove placing second and Green third.

Marco Cirone, from Toronto, is fourth overall in the Platinum Cup points and leads the Platinum Masters (age 45 and older) class in the No. 88 Mark Motors Racing Porsche. But his gap in Platinum Masters closed to 12 points over Carlos de Quesada after 2013 Gold Cup champion de Quesada won the Platinum Masters class round July 20 at Toronto in the No. 22 Alegra Motorsports entry for his first victory of the season.

The best championship race in the Ultra 94 Porsche GT3 Cup Challenge Canada by Michelin is raging in the Gold Cup (2010-13 model cars) class. Just 14 points separate the five regular drivers in the series. It’s truly anyone’s title to win – or lose.

Jerimy Daniel, from Candiac, Quebec, leads the Gold Cup with 104 points in his rookie season in the family-owned No. 75 TRC Porsche. Daniel swept both Gold Cup rounds July 19-20 at Toronto to lift his victory total to four this season.
