You will never, ever have this much traction.

On a more serious note:
A Cheetah's average peak acceleration is around 9m/s. So from a standstill, it should be able to reach 18m/s in 2 seconds if it can maintain that speed, or 40mph in 2 seconds, 60mph in 3 seconds. Realistically, after the first second it would drop off in acceleration considerably, but let's assume some uber-cheetah (as the pictured Cheetah clearly is) can maintain it and reach top speed (~70mph) in 3.5 seconds.
I'm fairly sure that some tires actually do have traction that good, since cars can accelerate that fast without slipping the tires.
One advantage a Cheetah has is reduced drag over the surface, since it only makes contact for short period, even if those contact points have much higher traction than a wheel does (but a wheel maintains lower traction for longer periods) but the force pushing down on the feet (per square inch) is probably heavier than the car, with all of the muscles and joints also working as a suspension to slow the moment of impact, resulting in that ability to spring against the ground without slipping.
That's my bench analysis. I'm actually really surprised their acceleration is that high, certainly better than quite a few cars for the first second or so.

Okay, now, make a sudden turn and see how well it goes for you in a car. I think the cheetah still is going to win.

Nice analysis, but I think the OP may have been referring to the fact that the Cheetah is making a serious right turn and not slipping.

Is that cheetah rally spec? It looks like its got studs.

If the car weighed the same as the cheetah, no problem. That's the thing about traction, without weight, it doesn't do anything.
That being said, Cheetahs are truly terrifying as predators, thank god we have cars to outrun them in.

They come rally spec standard.

It's the same thing, if the Car weighed the same as the cheetah, it shouldn't be a problem, from what I know. The limits with cars is more do to with resistance and weight, not necessarily pure out-and-out traction.

Kind of kills your launch though, doesn't it?

Lateral acceleration in g is tan(theta), where theta is angle between the cheetah and vertical. Looks like that angle is ~60 deg, so tan(60)=1.7g. So no, no car I own can pull 1.7g. That cheetah looks like he is not sustaining that acceleration for any long amount of time, so we can call it a transient 1.7 g lateral acceleration, which is attainable on a non-aero car with very very sticky autox slicks on corner entry, or easily attainable in a full-aero prototype or formula car.

Assuming he's leaning 60 degrees from vertical, I get 1.7g. Corner entry on super sticky slicks, or anything with lots of downforce.

Yeah there's no way that's possible haha. If it was a shorter distance maybe....but a Veyron can probably hit 80-90 mph in that short little run in the video.

Hussein Bolt takes 8-9 seconds to reach around 25mph. Chrisano Ronaldo is not a sprinter, much less an Olympic-level sprinter, and the Veyron can reach 25mph in probably about 1.2-1.5 seconds, at most.

Right. It's not even in the realm of possibility.
