The auto universe has shifted from four- and five-speed automatics to eight-speed gearboxes with remarkable speed.
Six-speed automatics, though still widespread, barely had time to claim status as exotic gearboxes before they were leafrogged..
Chrysler Group pioneered the eight-speed transmission in mainstream models, beginning with the 2012 Dodge Charger and Chrysler 300.

The qualifier: "Over their lifetimes, vehicles equipped with TorqueFlight eight-speed transmissions are project to save their owners" the stated amounts, collectively and globally.
