IMSA: Class breakdown revealed through 2016

Leave a comment

IMSA has revealed the class structure breakdown for the next three years. The items of note include the extension of the Prototype Challenge class from 2015 to 2016 and, perhaps more noteworthy, the adopting of full FIA-spec GT3 cars for the GT Daytona class from 2016.

GTD currently operates with modified GT3 platforms, and a spec rear wing and splitter, among other closed elements.

Here’s the release from IMSA:

Officials from the International Motor Sports Association (IMSA) today confirmed the structure and specifications for all four of its current TUDOR United SportsCar Championship classes through the 2016 season.

“It is important to all of our stakeholders to have a clear understanding of where the TUDOR Championship is headed from a technical standpoint, which we now have established through 2016,” said IMSA Vice President of Competition and Technical Regulations, Scot Elkins. “This will enable our manufacturers to build race cars with these specifications and timelines in mind, and allow our competitors to make fully informed investment decisions for the future.”

A breakdown of each class is as follows:

Prototype (P)

The Prototype class will continue to consist of Daytona Prototypes, race cars built to LM P2 specifications per rules established by the Automobile Club l’Ouest (ACO), which governs the 24 Hours of Le Mans, and the DeltaWing through 2016. Last fall, officials from IMSA, the ACO and the Federation Internationale de l’Automobile (FIA) World Endurance Championship (WEC) jointly announced these Prototype regulations would remain in place for three seasons. A new, globally unified Prototype format for all three organizations will be introduced in 2017, with a planned vehicle life of at least three years (through 2019). The Prototype class will continue to feature predominantly professional driver lineups while also allowing pro/am driver combinations.

GT Le Mans (GTLM)

The GTLM class adheres to GTE specifications established by the ACO. New GTE technical specifications will be introduced for the 2016 season, with a planned vehicle life of at least three years (through 2018). The class, which includes factory-backed teams from many of the most iconic automotive brands in the world, will continue to feature professional driver lineups while continuing to allow pro/am driver combinations.

Prototype Challenge (PC)

The Prototype Challenge class will maintain its current format through 2016, with every team using ORECA FLM09 chassis and 6.2-liter Chevrolet engines. Driver lineups will continue to require a mix of professional and amateur drivers.  Beyond 2016, the class will be further evaluated once the vehicle design, performance levels and cost is finalized for LMP3 and the new Prototype referenced above

GT Daytona (GTD)

The GT Daytona class will utilize its current race cars through 2015. In 2016, the class will adopt full FIA GT3 specifications for all of its cars. Traction control, Anti-lock Braking Systems (ABS) and the full FIA GT3 aerodynamic specification will be allowed beginning in 2016. An Adjustment of Performance process will be managed through restrictors and weight. Driver lineups in GTD will continue to require a mix of professional and amateur drivers.

Graham Rahal survives Road America to finish eighth

Graham Rahal and Rahal Letterman Lanigan Racing faced a roller coaster of a race during the Kohler Grand Prix at Road America on Sunday.

He was a rocket off the initial start, jumping from sixth on the grid up to fourth exiting turn 1, but was almost immediately ordered to surrender a position for blocking. He quickly slipped back to sixth, and then began plummeting down the order as he battled an oversteer condition that saw his car chew through its rear tires more quickly than others.

Forced to abandon the planned three-stop strategy, he and the No. 15 Gehl Honda team switched to a four-stop plan that saw him drop well outside the top ten at times.

However, they kept plugging away and rebounded nicely in the second half of the race to eventually finish in eighth. While he would have liked to finish higher up the order, Rahal knows that he and the team got everything they could out of it.

“The car was a handful today. I knew about five laps in that I didn’t have the pace for a three-stop strategy,” Rahal revealed post-race. “We tried as best we could to work with what we had during the race and overcome it. I would have obviously liked to have finished better, but eighth is about as good as we could do today. We struggled with a very loose race car all weekend and just couldn’t put a dent in the problem. We worked awfully hard but just missed it this weekend.”

The eighth-place finish keeps Rahal in the championship hunt. Rahal now sits seventh in the standings, 11 points behind fifth-place Josef Newgarden and 72 behind championship leader Scott Dixon.

Ed Jones continues steady run with seventh at Road America

Dale Coyne Racing’s Ed Jones has made waves in the 2017 Verizon IndyCar Series season with a string of solid performances that belie his rookie status.

And Sunday’s Kohler Grand Prix at Road America was no different.

The 22-year-old battled an oversteering car most of the weekend at Road America, and had to navigate a little carnage late in the race as Alexander Rossi and Ryan Hunter-Reay both fell through the field with front wing problems.

However, Jones weathered all storms to finish an impressive seventh, his fifth finish inside the top 10 this year, and his best finish since his third place at the 101st Indianapolis 500 presented by PennGrade MotorOil.

“It was a really tough race,” Jones said of the effort. “We had a loose car yesterday. It was loose, but fast, for qualifying, and today again the car was really loose. I was hanging on the whole race, but the team had some good pit stops and we were able to move up.

“Obviously, the strategy was pretty similar to everyone else. Everyone was aggressive out there. It was hard racing but we came out with a seventh place and we moved up a little bit in the points.”

The seventh-place run sees Jones maintain his position in the top ten in the championship. He currently sits tenth in the standings, three points ahead of Chip Ganassi Racing’s Max Chilton.

AF Corse has confirmed that Toni Vilander will race the No. 71 Ferrari 488 GTE in next month’s FIA World Endurance Championship round at the Nürburgring in place of Sam Bird, who is tied up with Formula E commitments in New York.

Vilander currently races full-time in the IMSA WeatherTech SportsCar Championship with Risi Competizione, and appeared at the 24 Hours of Le Mans two weeks ago.

The Finn won the WEC GT drivers’ title in 2014 and last raced full-time in the series in 2015, but will return at the Nürburgring in place of Bird, who confirmed on Monday that he would be prioritizing his Formula E commitments on the July 16 weekend.

Vilander is relishing the opportunity to race alongside Davide Rigon in the No. 71 Ferrari, and is eager to bounce back from an early retirement at Le Mans.

“I’m happy to be able to return to the FIA WEC with the 488 GTE of AF Corse team. This is my chance to cancel the disappointment of the 24 Hours of Le Mans as soon as possible,” Vilander said.

“Car number 71 is in the top places of the championship standings, and I will give all I have to achieve the best possible result at Nürburgring, to help Ferrari in the manufacturers’ championship and Davide Rigon in the drivers’ ranking.”

The British Grand Prix weekend will expand to a four-day schedule next month as Formula 2 and GP3 practice running gets shifted to Thursday.

On-track running for all Formula 1 events traditionally takes place across three days – Friday to Sunday, bar Monaco, where practice is on Thursday – with support events following a similar format.

Silverstone has confirmed its schedule of events for the British Grand Prix weekend, with F2 and GP3 practice slated for Thursday July 13.

F2 practice will run from 15:30 to 16:15 local time at Silverstone on the Thursday, followed by GP3 running from 16:45 to 17:30.

Both support series will hit the track again on Friday for their respective qualifying sessions, taking place after F1’s second practice in the afternoon.

The remainder of the race weekend will go ahead as usual for F2 and GP3, having one race each on both Saturday and Sunday.

The F1 schedule for the weekend remains unchanged, with FP1 and FP2 on Friday, FP3 and qualifying on Saturday, and the race on Sunday.

Both Renault and Williams will take part in special show-runs during the grand prix weekend as part of their 40th anniversary celebrations.
