A modern vanilla sedan can do 0.9 g, maybe more with good tyres. I saw a video on Youtube of some guy fitting a triangulated 4-link suspension to some chrome-bumper car, and managed to get 0.52 g on cornering, which seems rather poor. Must have had sh*t tyres. Sorry, I haven't been able to find it again to get the details.
hI aLL! what lateral g-force can old cars achieve?

Oh, you should be able to get it to do about 50g if you T-bone it at highway speed.

Depending on the type of tyres, 0.7g really pulls it up. At 0.75g, with balanced slip angles, you're into a 4 wheel slide. Look into slip angles for answers to your question. The tyre is, in most instances, the primary determinant. The cornering force developed by a tyre in any scenario depends on slip angle, load, inflation pressure, camber angle, drive forces and braking forces.
Modern cars have very much improved tyres and suspension handling dynamics but I very much doubt you'll be getting 0.9g with *any* modern vanilla sedan because - physics.
