BMW M5, is famous for it's lightness and power, even a beginner could drive fast with this. But, this BMW M6 holds much more power than his older brother, the M5. For such a great power, the weight itself was sacrificed. And make it harder to turn in on a corner.
Here's a video for M6, and a little about M5 :
And some information from RoadAndTrack.com
But for me I'll choose M5 instead of M6, because I'd prefer a bit powerless car than a car that is hard to turn in.The M5 and M6 have many similarities, but the one thing that's identical is the drivetrain. AndBMW's almighty, all-conquering 5.0-liter 90-degree V-10 is simply magical. This is a supremely advanced powerplant that uses individual throttle valves for each cylinder tied to an electronically controlled throttle-by-wire system; response is immediate. BMW's variable double-VANOS camshaft management continuously varies the valve timing to create better high-rpm power and a very consistent torque curve.The result is one of the most free-revving engines ever, along with an insanely potent 500 bhp at 7750 rpm and 383 lb.-ft. of torque at 6100. Fire either one of these V-10s up and they sound…like complete rubbish, at least at idle; think of the uninspiring, industrial-sounding hum modern turbodiesels make. But give the engine full wood and it sounds exactly as Peter Egan described in his First Drive of the M6 in R&T's July 2005 issue: "…like a Formula 1 car with mufflers." It plays such a rippingly beautiful song up to its 8250-rpm redline that you find yourself running up and down through the gears just to hear it one more time.All this power is harnessed to a 7-speed sequential M gearbox (SMG) operated either by steering-wheel paddles, a center console lever or you can just leave the system in full automatic. This third-generation SMG is far superior to any before, providing jerk-free (computer-controlled) clutch slips as you pull away from a stop. This is the only transmission available for the M5, though a true manual (that's right, with three pedals!) is said to be in the works for the M6. Incredibly quick (though abrupt) full-throttle shifts in the Drivelogic's sportiest setting (of 11 to choose from) mean both the M5 and M6 chirp the rear tires going into 3rd gear.While this system (like Ferrari's F1 gearbox) is completely state-of-the-art, you do lose the driving pleasure associated with old-school techniques such as heel-and-toe downshifting. Personally, I'd also prefer the paddles to be steering-column mounted instead of wheel-mounted; as someone who shuffle-steers, it can get confusing as to where the proper paddle is.Surprisingly, neither car feels as fast as their identical 4.1-second 0-60-mph times indicate, at least in real-world driving. Which is strange, because 4.1 is fast. Really fast. Faster than a Ferrari 612 Scaglietti, every Aston Martin and the Bentley Continental GT. Equally impressive are quarter-mile times of 12.4 sec. (the few cars barely quicker include supercars such as the Ferrari F430,Lamborghini Gallardo and MurciĆ©lago and the Ford GT), the lighter — by 265 lb. — M6 showing a higher trap speed of 118.1 mph versus the M5's 115.8. Of note, we used BMW's Formula 1-like launch control mode (which won't be available in the U.S.) to achieve our best times; after you initiate the system, all that's required is to keep your foot to the floor — the computer manages wheelspin. But it's only good for a couple of launches before the clutch heats up and the system automatically shuts down.
