That's a great idea. Very good, we seem to think alike. I've always wanted a weapons system in my car with which to engage the police. Wouldn't it be great if they would actually put out an M5 with some of these design aspects??
On a serious note, two of those things are a possibility and would be really nice.
It would be great if the M5 were constructed of titanium and some of the other exotic alloys that are lighter and stronger than steel and aluminum. The performance figures - top speed, acceleration, and handling would all jump up considerably.
Imagine a titanium or beryllium engine block? The engine block is the single most heavy component of the car, and I imagine that the aluminum block of an M5 must account for 75% of the engine's weight, which I would estimate is around 500 pounds. That would make the block weigh in at 375 pounds. I'd have to go look up the weight of titanium and beryllium, but just imagine that we could shave 100 pounds off the block alone??
Think about the other components as well. Imagine we had forged titanium rims?? They've started using beryllium on bicycles, which is lighter and stronger than steel (but VERY expensive). Just think, we'd have 10 pound rims! Titanium driveshaft, pistons, rods, exhaust, anyone?
I also wouldn't mind a radar system that could simultaneously detect and pinpoint the exact location and distance to the location of a waiting cop car on the roads. Even if there was a situation where you have to run, you would know exactly how far behind you the chase car is, how in front of you the next cop is, and how far away the inevitable chopper is.
Great ideas StevewiththeM5
