A good car? That would be a sports car sir. The topic is about Front Engine Front wheel drives. And no, FF's are Inherently understeering perfectionist. And to be honest, manufactures dial in Understeer into a LOT of sports cars also. This keeps grandma jane who want's the nice shiny new ride...from ending up on the side of a cliff. And sorry, there is NEVER a time in a race where it would be advantageous to have the back of the car step out. If we are talking Time Attack or qualifying, then it's possible but not likely. If we are talking lap after lap and in traffic, sorry that is not true. If you watch any wheel-2-wheel racing anywhere you would be hard press to point out where in any track you can see the drivers stepping out the rear of the cars on purpose so they can be faster around a corner.
In retrospect, a driver in the real world my prefer to have the car Looser in the rear to make it easy to change directions. But hardly does a racing driver purposely steps out the rear of the car during a race.
You can have front wheel drive sports cars. Hot hatches are pretty much the definition. Yes, road cars tend to have understeer dialed into them but it doesn't mean that you can't make them oversteer.

There are plenty of times in a race when you want the back to rotate in a controlled way. Note that, in a controlled way. You'll note that I never said you should oversteer to be faster, I simply said that there are times when you'll want oversteer.
If you're in traffic and you need to change your line mid-corner but you're already at the limit of grip, you're going to have to slide one end of the car. If you've had to go deep into a corner and want to get the car turned quickly it can be advantageous to flick the back end around. And so on. Car positioning, rather than car speed is what I'm talking about. Controlling the angle and attitude of your vehicle is important.
None of these things are strictly faster on the clock, but you're racing other people, not the clock. You do what you need to in order to get around and in front of your opponents even if they would be sub-optimal in a time trial. The fastest way around the track isn't always the fastest if someone else is holding that line, so you may need to be creative.
Want an entertaining example of someone using oversteer to good effect?

Watch segment 4 from about 3:45. Jenson Button intentionally uses oversteer to spook the other driver into not passing him back.
