Vehicle Dynamics

What are vehicle dynamics?

Vehicle dynamics describe how a car moves longitudinally, laterally and vertically. Accelerating, braking, steering – every force acting on the car and the way it responds. Vehicle dynamics is the science of why a car behaves exactly as it does.

The three axes

Vehicle dynamics splits into three dimensions: longitudinal dynamics (acceleration, braking), lateral dynamics (steering, cornering) and vertical dynamics (springs and dampers). All three interact – brake in a corner and you mix longitudinal with lateral (see trail braking).

What influences vehicle dynamics?

Tyre grip, weight distribution, centre of gravity height, tyre width, spring and damper setup, aerodynamics. A Porsche 911 has a rear-mounted engine, high rear axle load and a low centre of gravity – which gives it a very characteristic behaviour. A mid-engined sports car such as a 718 Cayman feels completely different, because the masses sit elsewhere.

Experience vehicle dynamics with ESC

On ESC track days you learn how different Porsche models respond. Our coaches explain the mechanics in theory and in practice. You feel the difference between a rear-engined and a mid-engined car directly from the driver's seat. Experience vehicle dynamics live.
