Porsche's new race car says no to turbos and yes to side-exit exhaust

Porsche was pretty confused about this new RSR model until its unveiling on Saturday at Goodwood at the Festival of Speed. Taking up one of the most successful motorsport models of recent history, the new 911 RSR offers many shoes to fill. Picking up where the outgoing car came to a halt, the new RSR features a naturally aspirated six-cylinder naturally aspirated 4.2-liter engine (still mounted in front of the transmission in a mid-engine configuration). with a wider torque band for better maneuverability.

The most important change is just below the massive lateral suction duct, a new lateral exit exhaust. According to Porsche, this new routing method helps to reduce weight and help aero submarines. Considering that one of the Porsche was set aside at the 24 Hours of Le Mans this year with a cracked exhaust system, it could also possibly reduce the points of failure. The sad news, dear friends, is that it is losing the signature of the Porsche 911 RSR that we have come to love. The new RSR and the outgoing model were spied together at Monza, and you can hear the difference in tone in the video below.

The current midrange RSR, introduced for the 2017 season, has proved very competent. During the FIA ​​WEC 2018-2019 season, the Porsche team has won three GTE Pro class wins, including Le Mans and the World Championship, as well as seven wins in eight races in the GTE Am category. things are even better for the IMSA 2019 season, with 911 RSR dominating the first half of the season, winning the last four races of the 12 Hours of Sebring.

While the 911 RSR competition is in the process of pulling out completely (Ford GT and BMW M8 GTE) or switching to turbo (Ferrari 488 GTE, Aston Martin Vantage GTE), Porsche remains firm in its commitment to natural aspirations. Hoping that the team manages to get some of this great sound in the coming months.

The car made its public debut on Saturday at Goodwood, but it must be ready for the race in just two months, as the 2019-20 FIA WEC season begins with the Silverstone 4 Hours on September 1 and ends 8 laps later. at Le Mans. June.
