"Leisurely" is a good way to describe the typical low speed acceleration with the Ultramatics behind the in-line 8 engines, Gear-start excluded. Of course once they shifted into direct drive their acceleration was the same as any other similarly powered standard shift car in high gear. With the Twin Ultramatics, you not only had the option of using the "D" range with it's 3-speed option, you also had a heck of a lot more power and torque available. Performance with the V8s and Twin Ultramatic could be quite impressive, even exhilarating for the era, and enough if you did it regularly to tear the transmission apart, as often happened.
