[RELEASE] 1955 - Nardi Bisiluro - v0.1

CSP 1.76 minimum is required for all the features to work properly

History:

The Nardi Bisiluro was a weird little car that raced at Le Mans in 1955.  

It was a collaboration project between the racing driver Dr Mario Damonte, architech-engineer Carlo Mollino and Enrico Nardi.

Carlo Mollino designed the streamlined, asymmetric, Twin-Boom body.
It was built by artisans of CA.MO. Rocco Motto and made of aluminium.

Nardi had the strange task of building a chassis that could fit inside the already built body.

The right side contained the engine, gearbox and differential.
While the left side hosted the driver and the fuel tank.
The whole car only weighted 400kg.

The Bisiluro only raced at Le Mans for 2 hours and had to be retired after a crash.

Rumor says that "It was so light, it was blown away by a passing Jaguar".
Truth is, the drivers complained about the pore weight balance, making the car very hard to drive and resulting in a crash.

Mod Informations:

First a small disclaimer:
Very few information, photos and data exist for this car.
The blueprints available online are early sketches and completely wrong.
3D modelling was mostly done using low resolution photos upscalled via AI

This is more an interpretation of what the Nardi could have been, more than an exact replica.

We made it fun to drive, while trying to keep some of the quirks.

Aerodynamics and CFD Simulations:

Some sources mentioned the car could have produced downforce thanks to it's middle section in the shape of an inverted airfoil.
Even if our model isn't an exact replica, we decided to run a CFD Simulation as an experiment.

The simulation was done on airshaper.com, an online service that let you upload a 3D game model and run a CFD simulations in a few minutes.

Result is Yes, it does produce downforc: 9.952kg at 150kph ...
But it is caused by the radiator flaps added to improve cooling for Le Mans and present on our model.

Cd is 0.293 for a frontal area 0.978 M²


Engine damage and Powerloss:

The engine will loose power past 50% of life. Once at 25%, it will start to malfunctions with throttle cuts.

Working gauges:

All the gauges are functional. When the engine gets damaged, the oil and water temperatures will rise.
A thermal system isn't simulated, but it will give the possibility to turn off the ugly damage UI of AC and get fully immersed.

A check engine red light will also turn on at 30% engine life.


Weight Distribution:

The layout of the Nardi makes the left-right weight distribution quite ... interesting.

With a full tank of fuel, the car is almost balanced, but with an empty tank the left side is heavier.
It those conditions the car will be easier to turn in the left direction and will tend to go right under heavy braking.


AI Version:

The AI struggled a lot with the un-balanced weight distribution so a version without it is included.


Requirements and Recommendations:

CSP 1.76 Minimum
Driver model by Mr.Malarkey:

We recommend to turn off the "soft-lock" in the Content Manager
It's in settings->assetto corsa->controls->force feedback->Miscellaneous

We also recommend using between 94 and 96% of Grip

Special thanks to Ilja Jusupov for adding the new engine damage functions we suggested, and for all the other features of CSP that make this mod more fun to drive.

Hope you enjoy :)
