Porsche’s 2017 GTE contender could feature a turbocharged engine after all, with the new-generation 911 RSR having been spotted testing at Monza, ahead of its race debut early next year.
Two of the new rear-mid engined Porsches, along with a 2016-spec Porsche 911 GT3 R, are at the Italian circuit this week, in what’s believed to be one of the first tests with the GTE car outside of its Weissach test track.
While initial reports pointed towards the car retaining a version of its normally aspirated flat-six powerplant, photos and multiple eyewitness reports from Monza indicate the German manufacturer could have opted with a twin-turbo instead.
Side intakes are visible from the above photo, in the same position as the Porsche 911 Turbo S. The road-going model features a 3.8-liter twin-turbo flat-six.
Porsche unveiled preliminary details of its 2017 GTE car last month, although omitting any side profile photos, or technical details.
It’s understood the car also features a revised engine and gearbox placement, via waivers from the FIA and ACO, in order to be on a more equal playing field to the new mid-engined cars from Ford and Ferrari.
Aside from the new intakes, the photo shows a redesigned rear wing, as well as reshaped rear-end, likely due to the revised engine placement.
Both CORE autosport and Manthey Racing will continue operating the factory programs next year, in the IMSA WeatherTech SportsCar Championship and a planned full-season return to the FIA World Endurance Championship, respectively.
