Is there any other hypercar with exhaust tips LIKE THE ONE YOU'RE SEEING NOW?! Last time I checked, only this one has a pair of Akrapovic-tuned exhaust tips that are ALSO AN ELEMENT OF THE DIFFUSER, MY GOSH!!! And yes, those are the exhaust tips. The silver-y squircle in the middle is there to help keep the batteries cool.
The question stands. Now I shall go off and suggest to Under Suzuki that he equip his S15 Silvia time attack weapon,
the rear aero setup of which looks like this,
with the Regera's exhaust design. Sure, the pipe on the S15's out the side, but there are ways around that. LOTS of ways, judging from the amount of space I can fit in that rear end.
