It also "might" be an A4 which is similar to the F4 in nose, air intake, & tail, but I agree, it most closely resembles at F4 for the split second you can see it on screen.
I love that this is a prequel & shows both early/original BB & that the Autobots were here for quite some time trying to find the spark, or at least a recon mission was.
I don't know the girl but its cool that she's filling in the spot where the early Witwiki was supposed to be.
