"The legend 718 is about to return," the German automaker said.
The 718 name was last used on a Porsche racecar. The video highlights the contemporary 718's racing roots.
Car shoppers who are unfamiliar with the 718 designation, which refers to a ground-breaking sports car Porsche introduced in 1957, are treated to some footage of the car in several races.
Porsche built the midengine 718 from 1957-'62 as a successor to the 550 Spyder.
Porsche has not confirmed if the new 718 Boxster and 718 Cayman will carry the 2016 or 2017 designation. The two will be renamed following a midcycle update in 2016.
It is not clear if they will debut at the 2016 Detroit Auto Show or at a subsequent event.
Both will use turbocharged four-cylinder engines, but U.S. launch timing, pricing and technical specifications have not been announced.
Porsche said the Boxster will be positioned at a higher price level than the Cayman.
Edmunds says: Porsche whets car shoppers' appetites for the 718 Boxster and 718 Cayman with this teaser video.
