They removed the flames livery from the Pigeon

 

as far as cut content goes, there's also the 600cc and the 660 diesel engines for the pigeon, and some would argue the old d-series marauder config.
for unused assets, there was the sling tow truck upfit mesh for the d/h series,

for configs, there's also a street homologated config for the bolide 320 GTR with no json file, and there was a D15 pickup Zeta config planned, made to resemble gabester's old S10 mod from RoR.

and if you want general unused assets that still exist, the I-series has "2000" badging despite having no 2.0L engines available, the modern ETKs have "V12" exhausts, and accommodation in the badge textures for 8,10, and 12 cylinder engines.
the SBR also has adaptive "S2R" suspension parts in-game, the barstow has a Node-O-line racing skin that's not used on a vanilla config, and the DT40L's skin UVs are set up for a longer articulated body.

there's definitely more than this, I just can't think of it now.

 

200BX X-Type Spoiler
Hopper Two-Tone Skin
Probably a lot more skins

 

Also have new HD European police flashing lights models in game files (maybe for next or update or further)

 

Unused ready section of the tach on modern etk’s. Also unused eco light (or some dash light like that I forget what specifically)
