Yes, yes it is and Unobtanium suffers from envy for not having the Sport Mode on his vehicle.
It's OK, he can always test drive one with a Sports Mode.
I encourage him to do so. Then he will realize how awes it is. Because yes, it doesn't make the cx5 "faster" than a cx5 without it. But it changes just enough to really make it an appealing feature for when you wanna have some fun.
