How we verify BMW 645Ci performance data
We include only independently published road-test results from automotive publications. Manufacturer-claimed 0–60 times are excluded unless clearly labeled. When multiple publications test the same BMW 645Ci trim, each run is listed separately — weather, tires, surface, rollout, and instrumentation all affect results.

We have verified test data for 1 model year. Each year shows every recorded run, the publication that measured it, and the trim-level details.
Every figure is sourced from published road tests by Car and Driver and Motor Week. We don't use manufacturer claims — only independently timed runs — so the numbers reflect what the car actually does.
0–60 and quarter-mile results depend on driver technique, ambient temperature, tire condition, road surface, altitude, and testing instrumentation. A published figure is a single sample, not an absolute — which is why we show the range of verified runs rather than one number.
