The Zenless Zone Zero 1.7 update will release two new playable characters, namely Vivian and Hugo. This means that the upcoming version will also introduce their signature W-Engines.
Luckily, a reliable source on X claims that both W-Engines are S-rank and has shared their stats and effects.

Two new S-rank W-Engines in ZZZ 1.7
According to@hiragara on X, the Zenless Zone Zero 1.7 update will introduce two new S-rank W-Engines. Their names are currently unknown, but they are Vivian and Vlad Hugo’s signature W-Engines.
Here are the stats and effects of the new gears in ZZZ 1.7 at level 60 and rank 1:

Vivian’s signature W-Engine
Vivian’s W-Engine is pretty good since it provides a lot of Anomaly Proficiency bonus from both its second stat and passive effect.

Hugo’s signature W-Engine
Hugo’s signature W-Engine also appears to be very strong. The second stat gives a CRIT Rate bonus, while the passive effect significantly boosts the CRIT DMG bonus of Hugo’s [EX Special Skill], [Chain Attack], or [Ultimate] after he deals Ice DMG to enemies. The bonus increases even more when he hits enemies in a Daze state.
The data is from the beta, so the stats and effects of the W-Engines might change upon official release of the update.
