- 0-60 km/h (0-37mph): 2.4s for the 1M (this Sport Auto test)
- 0-100 km/h (0-62mph): 4.7s for the 1M (this Sport Auto test) (4.9s being the official figure quoted by BMW).
October 2010, when some journalists had driven the 1M test mule:
"BMW claims that this 3308-pound machine will sprint from 0 to 62 mph in 4.3 seconds. Top speed will be governed to 155 mph [250 km/h], but there will be an option to raise Vmax to 168 mph, [270 km/h] as with other M cars." Later, BMW seems to have muzzled 1M performance information in official figures releases (no trespassing on the M3 territory:
"BMW engineers and execs have been quoted several times saying things like «it won't step on the M3's toes»") (source:

Here's what Belgian forum fellow M3Power79 registered with his stock 1M and stock tires (PS2) during a session of 0-62mph runs (MDM Mode activated) last Spring:
- 0-60 km/h (0-37mph):
1.8s
- 0-100 km/h (0-62mph):
4.4s

Getting sub 4s for the 0-100 km/h is possible with a tune (3.91s was already clocked with a JB4 tune).

1M: Cw value of 0.35 in the wind tunnel + rear uplift of 37 kg at 200km/h. For your well-being you don't want to know the rear uplift figure when the 1M is driving at top speed. From hindsight, actually not unreasonably of BMW to have shelved the plan to make the option available to raise Vmax to 168 mph (270 km/h) real top speed. As a matter of fact, driving the 1M at >220 km/h on a German Autobahn gets you the uncomfortable feeling that things turn rather
'fishy', especially when it's windy. At such high velocity, you hesitate staying around in the 220+ km/h zone as the 1M simply does not feel as rock solid running on rails as an M3 or an M5. It may be subjective but the Cw and rear uplift figures seem to confirm what your mind experiences.
