What's the "handling" stat?

At first I’d assume it’s the ability to steer, because all of my cars understeer when not drifting, but the existence of oversteer as a negative car quality means that handling must be something else. Maybe how fast it can turn?

I’m starting to purchase more expensive cars, and trying to figure out if it’s worth getting as much as the acceleration stat.

stats are inaccurate once you upgrade but it means how many lateral G’s it can pull, basically how fast it can turn before it loses grip.

It’s 1.7x for FXXK, very high, is it useful in fact?

Handling = lateral grip.

However, this is not the only important stat for actual handling! Launch is as important if not more on slower corners. Launch is acceleration off the line.

This is why AWD cars usually have inferior handling stat yet perform better than RWD cars in races, as most of the AWD S1-class cars and above have a launch rating of 10, as opposed to any RWD car.
