Unless that means the Panamera inspiration in the SBR4, but that's only really in design (and it ends up being MFG because of how all these designs are interpreted). Problem is that the K-Series is based off the Z4 and SLK-Class. The furthest successors we can get for both inspirations is the Z1 and the 190SL, but the 190SL is from the 50s-60s and the Z1 went into production in 1989, which doesn't fit the car described in my suggestion. Also, why a Hirochi based on a Porsche? As far as I know, the only connection to Porsche was the bits of design in the SBR4. That would better suit a new MFG vehicle.
SBR4 is IMO shooting brake version of Nissan GT-R, with many cues from other Japanese sports cars (Lexus LFA, etc.)
It's a modern Japanese sports car, kinda like a lower-end Eastern 911.

Not sure about the model name. I'd say something like "Plantlife" or some other strange name like that.
I just thought abought the starwind an I looked at other ford vans to see if one could be a starwind classic
2018-2022 ETK V-Series (BMW 4-Series Coupe/BMW 8-Series/Mercedes Benz C-Class Coupe) It is a... 2010s-2020s German front-engined sporty luxury coupe. Based off the 8-Series coupe, but shares a similar rear design (and the back of the side window-lines) from the C-Class Coupe and takes some cues from the 4-Series as well, with a revised ETK grille as well. Why do we need it? Because we don't have any vehicles surpassing the late 2020s, nor do we have any modern sport luxury coupes either. (No, the K-Series is only a sport coupe, and has less luxury features)
ETK had different indexes in the 80s, seeing that I-series name was discontinued. --- Post updated --- 800 series coupe?
The I-Series is more of an executive car and the 800-Series is a compact exec, judging by the engines. It may be relatively small because executive cars' dimension could be growing slower in the Beam world than in ours, and because you compare bumperless dimensions to real execs with bumpers, while the I-Series' bumpers aren't that big for 80s standards. Also, how do you explain the K-Series?
