9.X5M 1:43.72
10. E60 M5 1:43.77

Now GTS and CRT are special addition purpose built true track ready cars this was not surprising in least. I'm more interested in the standard cars,such as a normal M3, M5, and 1M this is where it gets interesting M5 is just three hundredth of second slower than the special edition M3 CRT now that's impressive even more so was how well 1M did considering its price and power now that amazing. So if you are ranking them as standard M cars, non special edition cars this is how they would rank

1. M5 1:38.90
2. 1M 1:40.18
3. M3 1:40.52
4. M3 sedan1:40.60
5. M3 vert 1:42.63

So to answer your question yes standard M5 is faster than the standard M3 around the track. And to answer a bigger questions yes New modern higher horsepower heavier sport sedans and coupes can trump a lighter weight Less powerful sport sedans and coupes go figure.

Of bigboys the Panamera was faster 1:38.13 than the M5 1:38.90, but the M5 with more than 2 sec faster than the E 63 AMG 1:40.59

Good information. I believe the original comparison was E60 M5 to E92 M3 but you're right that these new, heavy beasts are capable of astonishing lap times. 4,000 lbs is the new 3,000 lbs! Tire technology plays a huge role as well. All that said, I expect the F80 M3 to put down some stonkin' fast numbers and to be comfortably faster than the F10 M5. If the 0-1000m numbers BMW is quoting are accurate, the new M3 will basically render the M5 pointless.
