Comparing 424 to Max Verstappen’s 2025 pole lap in the Silverstone circuit. 424 is around 5 seconds slower, but this is very close to F1 race pace. The main differentiator is mass:

424: ~950 kg F1 (qualifying): ~800 kg

The 424 is simulated with Vehicle Physics Pro using the most recent engineering data available. EV racing is expected to keep improving in the coming years.

The 424 made it to the front page of this month’s RACE TECH Magazine! A six-page feature by @RaceTechmag covers the car’s development, designed using a simulator powered by Vehicle Physics Pro, turned into a full engineering tool.

I couldn’t be prouder to be a core part of this project 🤩

This is how we use data from the PERRINN simulator, powered by Vehicle Physics Pro, to stress-test a battery cell under the same conditions it would face in the real car. Top-level engineering at its finest.

All metrics are within spec, confirming that we can assemble the car using this cell.

Here’s the new version of the Torque Maps for the PERRINN 424. These maps now factor in powertrain efficiency directly into the power calculations, delivering a flat torque response at the wheel shaft.

How does an engineer design a SimRacing cockpit? By running a physical stress analysis, naturally! 😄

This cockpit, part of the PERRINN 424 project, is being designed with the exact physical dimensions of the real car and will be used to test driver position, ergonomics, and more.

How does the force feedback (FFB) model calculate the torque applied to the steering wheel device?

First, we set the maximum torque the device can handle (20 Nm in this case). The FFB component then calculates the steering load coming from the steering rack using its physical model and applies the corresponding torque ratio to the device.

Did you know that tire radius grows with wheel angular velocity? The faster it spins, the more it expands. At 360 kph (224 mph), the tires of the 424 grow by 5 mm. The new kinematic wheel model includes parameters to configure this effect, which is crucial since increasing ride height by 5 mm at high speeds significantly impacts aerodynamics.
