IMSA WeatherTech SportsCar Championship, Round 4, Mid-Ohio, USA
New racetrack, new challenge: After the street circuit at Long Beach, the IMSA SportsCar Championship will make its first appearance on the Mid-Ohio Sports Car Course on 6 May to contest round four of the season. The Porsche GT Team fields two Porsche 911 RSR race cars in the strongly represented GTLM class on the storied 3.634-kilometre circuit in America’s Midwest. The Porsche customer team Wright Motorsports tackles the GTD class campaigning two Porsche 911 GT3 R.
The Mid-Ohio Sports Car Course with its 13 corners is one of the most beautiful and time-honoured racetracks in the United States. Opened in 1962, the demanding circuit lies north of Cincinnati, not far from Lexington in the US state of Ohio. The last time Porsche won on this track was back in 2011 with the 911 GT3 RSR driven by Wolf Henzler and Bryan Sellers in the American Le Mans Series.
The Porsche drivers
The winners of the Sebring 12-hour race, Patrick Pilet (France) and Nick Tandy (Great Britain), contest the GTLM class sharing the cockpit of the #911 Porsche 911 RSR. Laurens Vanthoor (Belgium) and Earl Bamber (New Zealand) share driving duties in the second 911 RSR (#912) fielded by the Porsche GT Team. The GTD class, which was not contested at Long Beach, will be back on the grid at Mid-Ohio. Wright Motorsports tackles the race with two 911 GT3 R for the first time: The regular drivers Patrick Long (USA) and Christina Nielsen (Denmark), Porsche’s 2018 Selected Driver, share the #58 car, with Wolf Henzler (Germany) and Michael Schein (USA) contesting the remaining sprint races of the season in the #16 vehicle.
The Porsche vehicles
For the second race season, primarily the setup of the 911 RSR was optimised. Depending on the size of the restrictor, the motor, which is positioned in front of the rear axle, puts out around 375 kW (510 hp). The particularly large rear diffuser combined with a top-mounted rear wing provides strong downforce and aerodynamic efficiency. For 2018, Porsche provides its customer teams with an evo-kit for the 911 GT3 R. The ca. 368kW (500 hp) customer sport racer was designed for worldwide GT3 series.
The six-hour race takes off on Sunday, 6 May, at 13.05 hrs local time (19.05 hrs CEST) and runs over 2:40 hours. The race can be viewed live outside the USA on www.imsa.com.
