Olivier Jansonnie, the Le Mans team technical director, pair elaborated on how an aerodynamic discovery lead to the car going wingless. One of the biggest factors is the required downforce-drag ratio of 4:1 and the manner in which constructors are allowed to achieve this.
“The LMH regulation is new,” Jansonnie explained. “It opens many new opportunities. We started from zero, and we first spent quite some time reading the regulation carefully.
“We realised that we have a fixed target of downforce to achieve and that we have almost complete freedom to do it on the shape [of the car], a lot more freedom than we used to have in the past.
“This combination of these fixed targets and freedom makes you think and try to put some new ideas on the table. What we found in the end is that we can achieve the level of performance required without the rear wing.”
Pushed further by as to why Peugeot Sport made this choice, Jansonnie said: “The key thing in the decision to not use the rear wing is to find something to replace it, not really in terms of overall performance, but in terms of balance adjustment.
“We have a couple of ideas, which we need to develop on track. That part of the development is very sensitive to track testing. So at the moment we have some options.
