I’m minding my own business, walking my dog down Silver Lake Blvd. a few miles from downtown L.A. when I hear it. My first thought is that I’m listening to some sort of American small block, like a F-body Camaro’s LS1, the one with the square pipes. But there’s something different about it. Something… Not muffled exactly, but not pure. The sound was throaty and lumpy no doubt, but it was very deep, as if the treble had been turned way down. The new Shelby GT500? Kinda that same ball park, but not quite as straight-pipes and 100-octane sounding.
Turning around to look, I see a silver BMW 5-Series flying by. The wheels are black, there’s psychedelic camo-tape around the skirt and the telltale four tail pipes. This is the real deal baby, a barely concealed 2012 M5 and it just blew past before I had a chance to do anything. Drat! Good luck, however, showed its face as the light up ahead turns red. Dog in one hand, cellphone camera in the other, I sprint down the block to grab (sadly, only) one photo. The light goes green and Mr. M5 (who saw me setting up for pic #2) is off like a 600-ish horsepower super-sedan.
Back to the sound; compared to the X5 M/X6 M, something has changed. We tested the X6 M recently and Carlos Lago had this to say, “Sadly, the most unappealing part is the sound. Dry and without body, the exhaust note sounds like the first copy of “Gran Turismo” being played through a set of iPod earbuds.” Put another way, the twin-turbocharged X6 M sounds like two really big hair dryers. This new M5 – which shares the same basic 4.4-liter double twin-scroll turbo’d V-8 with the X6 M – sounds like it’s stuffed with a couple of hot cams. Let’s hope this mule is very close to production ready, sound-wise if nothing else.
