A lot of places here pump 98/99 RON. You think BMW get 507hp from an M5 on 95 RON?I'm not sure it's fair to say it kills it, to be honest. Most Americans consider performance in a straight line first and then cornering second.
Where? Everywhere I've seen so far (in California, Nevada and Arizona) only goes up to 91 MON which is about 95 RON isn't it?
