There are no shortage of automotive journalists praising neutral handling balance, sliding a car half way around a track, and condemning understeer as the enemy of speed. It's not just journalists, either. Forums for all sorts of cars are filled with people who hate understeer and try their best at exorcising every last understeering demon out of their cars. But is understeer actually that bad? Drifting vs Hot Laps Everyone seems to categorize the three distinct traits at the limit - "understeer", "neutral", and "oversteer" - this way: Understeer is bad. Neutral is good. Oversteer is slow but fun. And since most people don't get to drive a multitude of different cars, let alone push them to their limits, most opinions are formed based on professional reviews. That's fine in general, but there is a distinction between "fun" and "fast". Drifting is a lot of fun, yet everyone knows that drifting is not the fastest way a

But as you might know or have learned from reading the article, they aren't without their faults, which means engineers are always working to get around those limitations. You may not be surprised to learn that something like the Ferrari 488 GTB doesn't use a traditional limited slip diff, but it's not limited to super cars, far from it.

To keep things simple, I'll focus on two wheel drive vehicles. The vast (vast) majority of principles apply to all and 4 wheel drive vehicles, but there are some subtle differences that I'll
