Race Engineering: Racing car ride frequency ranges

Typical racing car ride frequency ranges are in the table below.

Ride RateVehicle Type
0.5 – 1.5 HzPassenger car
1.5 – 2.0 HzLow and moderate downforce race cars
3.0 – 5.0+ HzHigh downforce race cars
Baseline racing car ride frequency ranges

Front / Rear considerations:

Road car goal “flat car” –> minimise front to rear pitching –> Front / Rear ride frequency ranges are different –> 10-20% higher at rear.

Race car goal “performance” –> higher damping ratios –> less differences front / rear in racing car ride frequency ranges.
