This looks like an awesome rendition of the toon Rodimus.
I really am hoping that the recent trends in Takara MPs get followed here and we see alternate "also Hot Rod" color schemes.
Marvel Comics (dark magenta, no chest accent, orange hands, silver legs) would fit in well with the G2 Sideswipe they did (and a G2 faction logo would make it Marvel G2 Hot Rod).
The Fleetway color I showed was Dreamwave art based on multiple panels of the UK Fleetway-published G2 annual where they added a bit more contrast and made his dark magenta from the Marvel run more blue purple.

Here you can see various Rodimuses from the IDW Regeneration One book.
G2 Marvel Hot Rod (which is the same as G1 Marvel except for faction symbol) is behind Alternators and Animated Rodimus.
Key distinct features: Orange hands, silver thighs, red tinted feet (all more G1 toy accurate), dark magenta instead of red (even more magenta than the movie), no orange chest accent (like the Classics toy), option of G1 and G2 logos, oh and he had a scowlthat textended from the corners of his lips to his jaw (maybe a goatee?) and bags around his eyes.
IDW showed him with the latter day G2 logo here.
But here's his original design:

Edit: if it looks a bit plain, stare at the second design for awhile. I think there's a solid case for a darker magenta on magenta plastic for detail highlights. A subtle two-tone dark magenta might really pop.
If I recall correctly, it's because Marvel had to work off unfinished character designs. That's also why their Galvatron and Kup had different color schemes.
