Peugeot abandons wing-less concept behind 9X8 hypercar · RaceFans

Peugeot has deserted the bizarre idea behind its 9X8 hypercar which has raced with no rear wing since its introduction two years in the past.

The producer has revealed the primary pictures of its overhauled automobile. In addition to including a rear wing, Peugeot has revised 90% of its bodywork and adjusted from tyres of equal widths to wider rubber on the rear.

It determined to desert its unique design idea in March final yr because it launched into its first full season within the World Endurance Championship. Peugeot returned to the collection in July 2022.

Peugeot Sport technical director Olivier Jansonnie mentioned the workforce initially selected to race with no rear wing as that complemented their resolution to make use of 31cm width wheels on the entrance and rear of the 9X8.

“Initially, the automobile was designed for 31/31 tyres. Very a lot ahead aero distribution, very a lot ahead weight distribution as properly.

“And it simply occurred like that, truly, once they had been within the wind tunnel, the automobile was too draggy and had an excessive amount of downforce in comparison with the aero efficiency window. There was very brief and simple repair: We eliminated the wing and we realised that the automobile was truly not distant from the window.”

Nonetheless Jansonnie mentioned modifications to the laws between the beginning of the venture and the automobile’s 2022 debut prompted them to revise their design to make use of 29cm width tyres on the entrance at 34cm on the rear.

“Very quickly within the venture, we recognized that there was some efficiency potential in 29/34, however at the moment we weren’t allowed to do it,” he mentioned. “We principally developed a automobile the place the entire idea of the automobile was to run very a lot ahead aero to attempt to match the 31/31 tyres.”

The World Endurance Championship makes use of a Steadiness of Efficiency system which adjusts the burden and efficiency of their automobiles in an try to equalise the competitors. Peugeot has not gained a race with the 9X8 and Jansonnie mentioned the allowances they got below the BoP weren’t ample to make them aggressive with their unique design.

“We made selections which are now not the precise ones now and this distinction in efficiency was not sufficiently offset by the BOP,” he mentioned. “The concept was due to this fact to return to a automobile design that’s comparable that of our rivals automobile design, in order that it might then be given equal therapy by the BoP.

“For this reason we determined to drop the usage of an identical 31/31cm tyre widths on all of the wheels, selecting to suit 29cm tyres on the entrance and 34cm tyres on the rear.”

The revised 9X8 is “strictly talking… not a brand new automobile” he defined, “because it has the identical chassis, however there are plenty of upgrades.” Some parts have been repositioned and lightened to vary its centre of gravity and enhance the way it makes use of its tyres.

“So as to have a greater aerodynamic stability, we additionally had to have a look at redistributing the aerodynamic hundreds, which resulted in us redesigning roughly 90% of the bodywork parts, most notably including the rear wing,” Jansonnie continued. “In addition to all this, we determined to make use of this new homologation so as to add some reliability and efficiency upgrades to provide us the most effective alternatives within the championship.”

The revised 9X8, which additionally sports activities a brand new livery, will compete for the primary time within the Six Hours of Imola subsequent month.
