The opening text to Blade Runner says that the Nexus-6 replicants have enhanced strength.
The Nexus-6 replicants were superior in strength and agility, and at least equal in intelligence, to the genetic engineers who created them.
Blade Runner 2049’s opening also references this enhanced strength:
Replicants are bioengineered humans, designed by Tyrell corporation for use off-world. Their enhanced strength made them ideal slave labor.
Do all Nexus-6 replicants have enhanced strength?
I think that this would especially relevant for the “Is Deckard a replicant?” debate, since he would almost certainly be older than Rachael, a Nexus-7 prototype, but he doesn’t seem to have any sort of enhanced strength.
