"Approach angle" (reference 2)
The approach angle is determined by the horizontal line of the road surface and by the tangent line passing between the front
wheel and the most projecting low point of the car. The wider the angle, the lower the chance to hit an obstacle with the body
or chassis, climbing a steep slope or overcoming an obstacle.
"Departure angle" (reference 3)
The departure angle is determined by the same lines of the "Approach angle", and refers to the rear part of the car.
"Breakover angle" (reference 4)
The value of the "Breakover angle" is linked to the ride height of the car and indicates the attitude of the car to overcome a
wedge, more or less steep, preventing the car from resting on the ground with the body or chassis after touching the wedge
with its lowest and most projecting parts (usually the underbody), because this would highly reduce wheel grip which, lacking
adequate grip to the ground would not have sufficient grip to make the car move and slip. The higher the ride height, the wider
the breakover angle. Always bear in mind that the higher the ride height, the lower the stability, due to a higher centre of gravity
which reduces the side rollover angle.
