Hardware requirements to run the simulation in Full HD:

CPU: minimum Intel Core i5-7400 or Quad Core i3-10100/ AMD Ryzen 5 1600
RAM: at least 8GB
Graphics Card: Nvidia GeForce GTX 960 / AMD Radeon RX 560 or higher

Software requirements:

Unity Hub, you need to login or create a Unity account: It is the starting point through which will you will manage your Unity projects and software versions
Unity 2021.3 LTS (the project uses Unity 2021.3.45)

How to set up and open the project in Unity:

Open "project-424-unity" on GitHub. Then clone the repository to your computer.
Add the repository folder to Unity Hub: Projects > Add > Add project from disk. Select the folder with the repository.
Click the newly added project in the list.

How to run 424 in autopilot on the Nürburgring Nordschleife:

Open the scene "Scenes/424 Nordschleife Scene"
Play the scene. The car is at the starting point.
Press 'Q' to enable the autopilot. ('A' for an AZERTY keyboard)

All other features work normally: telemetry (T), cameras (C), time scale... (see left-bottom section of the UI for the features list).

How to drive 424:

Open one of the scenes in the 'Scenes' folder and play it.
Press 'I' to open the input settings. The first time it shows the default keyboard mappings.
Click the inputs and follow the instructions to map the inputs to your device. Currently, keyboard and DirectInput devices (with or without force feedback) are supported. Your settings will be saved and remembered.
Press the 'Gear Up' input to engage the 'D' (Drive) mode.
Drive!

Do not hesitate to read the README file for further details about this project. Of course if you face any technical issue, don't hesitate to leave a message on PERRINN.com or in the PERRINN WhatsApp community, our developers will be happy to help!

Engineering - Learning - Gaming

Before setting a new lap record at Nürburgring and racing at Le Mans 24h, PERRINN developers have created a virtual simulation allowing you to drive 424 on the most challenging track in the world : Nürburgring Nordschleife.

This simulation tool will help PERRINN members to validate technical choices made on 424 design. The influence of design or set-up modifications on performance and even reliability (behaviour of the battery for example) can be evaluated before any 424 prototype is built.

There is also a wide range of underlying objectives :

Create a robust platform for engineering/driving challenges around the world.
Participate in our digital innovation process to minimise physical testing and thereby reduce PERRINN's carbon footprint.
Establishing partnerships with institutions, firms, academies and create a network of infrastructures like Sim Rigs for research and entertainment.
Communicate about what we are doing and invite more talents and partners to experience 424 for themselves.

Have some fun enabling our community of members and every player in the world to drive 424 from home even before it has hit the track in real life.

A complete virtual racing experience

Based on Vehicle Physics Pro, an advanced simulation kit for Unity software, 424 Unity Simulation is the result of years of development. Thanks to a physics running at 500Hz, dynamic and aerodynamic behaviour of the car as well as tyre response and power unit are accurately modelled to deliver the best driving experience. A whole range of data is available at a glance thanks to an exhaustive telemetry system with more than 120 channels.

424 Unity Simulation remains absolutely handy thanks to a very user-friendly interface. The simulation supports any rig and steering wheel. Once at the wheel of 424, you can directly compare your lap time with the Porsche 919 Evo one (Nürburgring all time record) and the one performed by our official PERRINN simulator driver. Don't worry if you are not as fast as them yet: the integrated timing system will help you find where to improve. Switch your sim rig on and prove your abilities!

Before that, review the optimal trajectories aboard 424 with this video, it was made using the Unity Simulation.

Drive 424 around 2 legendary tracks

Although this tool has been created, in the first place, to support the development of 424 in the quest for a lap record around the Nürburgring Nordschleife, it is also possible to drive around another iconic track in the simulation : Silverstone.

The aim is to compare 424 directly with Formula 1 and LMP1 performances. The English circuit is also shorter and requires less driving skills to complete a lap. It is therefore easier for anyone to test the full electric prototype on this layout.

For those who do not have a steering wheel or do not feel comfortable with driving such a high-performance prototype: activate the autopilot and enjoy a ride aboard the autonomous 424. If you are attentive enough and play with the various camera perspectives available, you should be able to observe the active aerodynamics system working on the car. Send us your best pictures!
