The sDrive23i model for not available in the U.S. market.
The sDrive23i figures are a simple conversion unit conversion from those of the European model, or an extrapolation from other models.

When comparing European to U.S. figures, some might look illogical; for instance, 0 to 60mph & 0 to 100 km/h for the sDrive35is are both 4.8sec, while for the other engines they differ slightly.
