Just for the sake of the visual pun, I hope he's driving a Datsun 240Z or some other car with an equally long nose (Jag E-type would be peak, but I dunno how far Genki's licensing power has reached).
Of course, I know your post is just a fun joke, but unfortunately it looks like he will be using some kind of 4/5 door car.
The image is a teaser of Yamitengu shown at the end of Rolling Guy No.1's video, but this image did not match the emblem on his TXR2025, so it turns out that what was shown in this video was not his emblem but the car he will be using on the TXR2025.
If we look closely at the image with this in mind, we notice two noteworthy features:
The door dividing line that runs across the letter "N," and the front fender insert.
From the distance of the door split lines and the front fender insert, it's clear that Yamitengu's car is a 4 or 5 door car.
And from the shape of the front fender insert, some Twitter users seem to be guessing that his car is a VAB WRX.
Certainly, this reasoning makes sense.
The VAB WRX appeared in Shutokou Battle Xtreme, and they are remastering and reusing many assets from that game for TXR2025.
And Yamitengu (known as "Dark Goblin" in the English version of SBX) was a driver using the Hawkeye WRX in ITC. It's possible that he will use the new generation WRX in the new TXR.
As an aside, in Japan, Subaru cars such as the WRX were labeled as "cars especially favored by otaku."
And Yamitengu is a driver who clearly states in his profile that he is an otaku.
Maybe that's why he uses a WRX... well, that's probably why.
(Also, the robot drawn on the livery of his WRX at the ITC may have been a message from Genki implying that Yamitengu is an otaku...)
