Both oversteer and understeer\u00a0can happen as a result of the slip angle difference between the front and rear wheels of a vehicle. If that sounds confusing, read on.<\/p>\n\n\n

Before we go into the difference between the two, let’s define what slip angle means. Measured while the car is turning, the slip angle is the angle between the direction a vehicle is traveling and the direction that the wheels are pointing.\u00a0From an engineering perspective, the scientific calculations that determine slip angles are complicated. If you are interested in understanding the mathematical formulas that comprise this measurement, this article<\/a> from ScienceDirect is highly informative.<\/p>\n

The differences between understeer and oversteer are easier to understand by considering each individually. The following commonly asked questions and answers will help with that.<\/p>\n

Understeer Q&A<\/h2>\n

What Does Understeer Mean?<\/h3>\n

Understeer is a condition where your car turns less sharply when cornering than you (the driver) had intended. In other words, it’s a lack of your car’s front-end responsiveness when cornering.<\/p>\n

When understeer happens,\u00a0the front tires begin to slip first when cornering. Because the rear tires have road surface grip while the front tires have lost grip (slipping), the vehicle will turn less than if all four tires had grip. This physical effect is known as understeering.<\/p>\n

Front-wheel drive vehicles tend to be more prone to understeer because the front tires must handle both the lateral cornering force and engine torque. As a result, the front tires approach their traction limit more rapidly.<\/p>\n

What Does Understeer Feel Like?<\/h3>\n

The sensation of understeer is very subtle. You will likely feel a slight steering wheel judder. More importantly, you will visually sense that your car is veering outwards and away from the road-cornering center.<\/p>\n

What Causes Understeer?<\/h3>\n

Turning the steering wheel abruptly, or just too much for the vehicle’s speed versus the available wheel grip, exceeds the front tires’ traction. This forces the front of the vehicle to slide wide across the road surface in an understeer scenario.<\/p>\n

While understeer happens as a direct result of driver input, several other factors play a part. Weight distribution and suspension geometry affect measured understeer gradient. Power distribution, brake bias, and front-rear weight transfer also affect which wheels lose traction first in many real-world scenarios. In addition, causes of understeer can include:<\/p>\n
