If you really want some fun, get a bike engined kit car with a separate reverse box. 6 speed sequential in reverse with a 13k RPM red line, any one? 

Not so easy to snick it back into a forward gear in the middle of a J turn though. So I'm told.

Automatic      -              2.40:1      1.48:1      1.00:1      0.72:1      -               2.00:1      3.90:1


All these ratios are for the 3.0

So looking at the auto, what ever speed you could achive in 1st it looks like reverse is 20%ish slower.

Other way round. Reverse is higher geared than first.

So how fast is a 3.0 auto in 1st gear. ?

I don't normally look, but say 6.5K rpm upshift point divided by 2.40 and then 3.90 gives you 694 RPM at the wheel.

A 235/45/17 does 796 revolutions per mile so to get MPH: (694/796)*60 = 52 MPH. 

In practice, it would depend what the torque converter is doing, although at those engine speeds it should be pretty much solid.
