[Spy Video] 2019 BMW X3 M spotted testing at the Ring

In this video, a prototype of the BMW X3 M is spotted testing on the Ring. We really can’t hear the exhaust because the screaming of the tires overwhelms the exhaust, but so far, we like what we hear. The B58 engine in most modern BMWs already sounds better than the S55 engine found in the BMW M3 and M4, so the S58 in this new BMW X3 M should sound even better.
