The BMW M2 Competition (2018–2021) is quoted at 4.2 s from 0 to 100 km/h by the manufacturer for the 3.0 biturbo 410 ch (S55). That is a type-approval figure (410 hp, RWD), not a GPS run.
On the road, load, slope, tyres and phone GPS (about ±0.2 to 0.5 s) often stretch the time. Measure yours with OpenRank — no community average is invented.
Manufacturer vs real GPS
The 4.2 s figure is a reference. On the road, a smartphone GPS (OpenRank) measures speed from successive positions, not a wheel sensor. Expect a gap: rolling from 2–3 km/h, a slope, two passengers or worn tyres is enough.
Timing this M2 Competition 0–100 with OpenRank
- Install OpenRank (free, iPhone or Android).
- Pick a clear, legal, dry road with no traffic.
- Start recording before you come to a complete stop.
- Accelerate in one go until after 100 km/h.
- The 0–100 time appears in the trip history.
For the full protocol (launch, slope, cold GPS), read how to measure 0–100 km/h accurately.
