IMSA: Michelin returns to Watkins Glen for first time since 1999

1 Comment

The first TUDOR United SportsCar Championship series event at Watkins Glen International marks the first time that Michelin has raced in a major event at the storied circuit in nearly 15 years.

Michelin technical partner teams from Viper Team Oreca and Chamberlain Motorsport Viper swept the podium at the 1999 FIA GT Championship race at Watkins Glen in October 1999.

Competing in the GT Le Mans (GTLM) class in the TUDOR Championship, Michelin will try to match that success as its 2014 technical partner teams from BMW Team RLL, Corvette Racing, Porsche North America, Risi Competizione Ferrari and Krohn Racing Ferrari and also SRT Motorsports Viper. The Vipers take on their retro red livery from the standard blue and silver, starting this weekend.

The 3.37-mile, 11-turn circuit, with over 140 feet in elevation changes twice each lap, presents a number of technical challenges including long, fast straightaways ending in downhill cornering, uphill exits and a mix off high, medium and low speed corners and heavy braking zones.

“Our Michelin engineers and technical partner teams always look forward to the challenges of a new circuit, especially a legendary circuit like Watkins Glen,” said Ken Payne, motorsports technical director for Michelin North America.

“From a technical approach, extended tread life, consistent braking and cornering are critical. A six hour race also provides some opportunities to try different compounds and tire strategies,” said Payne. “Artistically, our tires are the paint that drivers and teams use to draw their lines for each corner and create their full canvas of the circuit.”

Michelin and its technical partners have all made use of various combinations of simulations and track tests in preparation for the Sahlen’s Six Hours of the Glen on Sunday, June 29.

“Simulations are extremely helpful and certainly get us pointed in the right direction, but there is no substitute for actual race miles to discover any changes in grip levels as the track evolves in race conditions to complete the picture,” said Payne.

Gabby Chaves is set to return to the IMSA WeatherTech SportsCar Championship at Watkins Glen International later this month.

The Columbian-American driver, who last competed in IMSA in 2016 – with the DeltaWing outfit – will sub for the injured Joao Barbosa – he hurt his wrist in a cycling accident earlier in June – in the No. 5 Mustang Sampling Racing Cadillac DPi-V.R in the Sahlen’s Six Hours of the Glen.

Chaves will partner Filipe Albuquerque and Christian Fittipaldi in the No. 5 Cadillac.

Chaves expressed gratitude for being asked to fill in, but kept his enthusiasm muted, noting that he is getting the opportunity ultimately because another driver got hurt.

“The first thing is of course that you never want to have an opportunity because someone got hurt, so this is an unfortunate circumstance with Joao having his injury,”said Chaves. “But I appreciate the opportunity to join the championship-leading team. Mustang Sampling Racing has had a strong start this year and hopefully I can help the team continue to have those kinds of results.”

Chaves added, “I love Watkins Glen, it is a great track and I am looking forward to racing the Cadillac Prototype there. I’m excited to be going back to endurance racing. With different classes all racing at the same time, there is a lot for the driver to deal with as you work through traffic. So I am looking forward to racing at the Glen again, and I really appreciate this opportunity with Mustang Sampling Racing.”

Chaves’ most recent IMSA event was the 2016 Sahlen’s Six Hours of the Glen, when he finished seventh in the Prototype class.

The No. 5 Action Express Cadillac currently sits tied with the sister No. 31 Whelen Engineer Racing Cadillac of Eric Curran and Felipe Nasr atop the IMSA standings, though Barbosa’s hopes of a driver’s championship are set to take an enormous hit with him missing Watkins Glen.
