Hopping into 0.9 – BeamNG.drive

Load sensitivity node properties are “noLoadCoef”, “fullLoadCoef” and “loadSensitivitySlope”

Tire’s overall grip is reduced with increased load

Lightly loaded tires have comparably more traction. This means less inside wheel spin with throttle in corners.

The cars behavior and balance at the limit is more progressive, cars do not “tank slap” as much when trying to recover from a slide

Cars can brake/accelerate with some 5-10% more force than they corner, because the wheelbase is longer than track, weight transfer reduces grip less in the longitudinal direction.

Camber affects maximum grip in a more accurate way, because loading the outside tire nodes excessively, reduces grip due to load sensitivity.

Vehicles, especially tall ones, are less likely to roll after hitting curbs or off camber situations, because the extreme camber reduces the grip through load sensitivity on the outside tire nodes.

Rolling resistance reduced another 10-30% by improving the node to ground collision code

Increased aero drag to compensate for reduced rolling resistance

Nodes have a new “softnessCoef” property, which changes the rubber’s hysteretic behavior. This allows them to be more sticky in transient situations. When used in wheels, this improves steering response and makes the tire less likely to be shocked loose from the road by sudden input or a bump etc. It can also reduce loss of grip at high speeds (250+km/h) to a basically negligible amount.

Tires have a tread coefficient that represents how well treaded the tire is (Slick = 0, mud tire = 1) we multiply this against a roughness coefficient in each ground type (mud has a high roughness, asphalt has very little) this means that a mud tire now works well in mud but mediocre on pavement, a slick works well on pavement but horribly on mud. Similar for other ground models.

Choosing the correct tire for the surface is more important now, as off road tires will perform well off road but not so much on asphalt, and slicks will be great on asphalt but practically useless in mud.
