However, a FWD car *can* exhibit a behavior that feels like oversteer, or lead to a spin, under specific extreme circumstances:
* Lift-off oversteer: This is the closest a FWD car gets to "oversteer". At high speed, if the driver suddenly lifts off the throttle (or brakes hard), the weight transfer to the front tires can dramatically reduce rear grip, especially on a slippery surface (like ice or loose gravel). This sudden loss of rear traction can cause the rear to step out, giving a sensation similar to oversteer. It's not technically oversteer because it's initiated by a lack of power, not an excess of rear-wheel power.
* Extreme situations: On very low-grip surfaces or with heavily worn tires, even slight inputs can upset the balance. Aggressive turning while accelerating can cause the inside rear wheel to lose traction, triggering a spin – though again, this is usually considered a loss of traction rather than "oversteer" in the purest sense.
* Vehicle dynamics modifications: Significant changes to the car's suspension setup (lowering the car excessively, stiffer springs, etc.) or adding significant weight to the rear can alter the weight distribution enough to make the car more prone to rear-end slip under hard acceleration or braking. This is unusual for a street-legal FWD car, though.
In summary, while a FWD car can't naturally oversteer like a RWD car, a sudden loss of rear grip under specific high-speed, low-traction, or improperly modified conditions can create a handling characteristic that *feels* and *results* in a spin similar to an oversteer situation in a RWD car. But the underlying cause and the mechanics are different.
