P424 - The car


“The 424 has to become and remain the fastest electric car in the world. PERRINN will not stop working on it until we accomplish our goal of winning Le Mans 24h.”

A thoughtful approach:

Project 424 is the global showcase for the PERRINN.com platform through the design, development and manufacturing of a unique machine using open source designs. The 424 electric hypercar is largely based on the LMP1 (Le Mans Prototype 1) chassis designed by PERRINN between 2011 and 2017. In 2018, PERRINN has integrated an electric drivetrain into its LMP1 concept in place of the traditional petrol hybrid engine and launched PROJECT 424. The electric drivetrain consists of a high voltage lithium-ion battery located inside the main chassis and 3 electric motors driving front and rear wheels using 2 single speed transmissions.

TECHNICAL SPECIFICATION:

    • Top speed: 224mph (360kph)

    • Movable aerodynamics

    • Autonomous mode with machine learning

A ground-breaking Autonomous Mode:

The system allows the brain of the car to drive on the race trajectory. It combines autonomous road car solutions with pre-recorded race driver inputs to create a safe and performant solution.

The driver drives a lap before activating the autonomous mode for the following lap. The car takes over and replicates the recorded lap. The system keeps the car on the trajectory and compensates for tyre degradation and changing conditions.

The driver can take back control of the car at any moment in order to manage traffic or other situations.
