My friend in California had mentioned that Ronin was on, though, which inspired me to pull out my DVD copy.
I apologize in advance for any errors, I've only ever been in an E34 M5 once (a '91, what a car...) I must own one some day... ah well, I'm only 18... all in time :)
While watching the "M5" chase scene, it became obvious that there is not a single real M5 shown in that entire sequence. It's obviously not a 3.8 (or it would have either the throwing star wheels or the parallel spokes). That eliminated the possibility of it being a 3.8... 3.6? No - no M5 badge to the right of the kidney grilles (which are not wide enough to be the 3.8 anyway). Additionally, the chrome strip around the windows, that's black space on a real M... the guage needles are white, not red, and do not have the M logo in the guages... the gearshift doesn't have the M logo on it... it's not an M steering wheel... etc etc etc.
They only time the wheels are basketweaves is when the tire gets shot. they're the turbine fan style again while the car goes over.
John Frankenhemier says in the DVD commentary they had four BMW's, and says they cut the engine off of one of them for most of the interior shots. They then towed the half-BMW around using a Mercedes 500E. Another of the BMW's was a RHD model, so the stunt driver could drive from the right, while the actor was on the left side with a fake steering wheel. He also says that they went to a race track to re-record all the sounds for the chase, and I presume that includes the engine noise. There are a few shots where guages are all at zero, so that must be the half car. The shot when they're in the tunnel and the guages are moving, and it looks like Dierdre is driving, I'm not sure how they did that one. John Frankenheimer says that's the RHD car being driven from the other side, but why do the guages show up on the left? Did they put in a LHD dashboard and put a hole through the glove box or whatever for the RHD steering column? I can't figure that one out...
Anyway... what engine sound are we hearing in the movie? It's obviously not the 518i... obviously not a V8 either. That limits it to the 525i, 535i, or the M5 3.6 or 3.8. My guess is it's the 525i. I've been extensively in a 735i, which sounds much MUCH deeper than the engine noise in the movie, while the sound in the movie has much more of a "honk" sound to it. I'd suspect the M engines sound deeper than the 525i, while having more of a "honk" than the 535i. Anyone know for sure what we're hearing in the movie?
