Sources & notes

This record describes the 2011 U.S. B-Class F-CELL offered through a limited California lease program. Other years and markets are not used to fill missing specifications.
The manufacturer’s exact-model-year launch release specifies 100 kW and 290 Nm. Displayed values are mathematical conversions to 134.1 mechanical hp and 213.9 lb-ft, not separate SAE-certified ratings. Its 136-hp figure corresponds to metric horsepower.
The original 2011 EPA guide reports 52 city / 54 highway miles per kilogram of hydrogen and a 190-mile range. Those historical values are not presented as current adjusted MPGe or range. Combined economy is not published in that guide.
The MBUSA model index identifies B 220 F-CELL (245.286) for U.S. model years 2011–2012. The EPA guides independently confirm California lease availability in both years.
Exact-year dimensions, transmission, seating, weight, cargo and hydrogen capacity remain unverified. The available U.S. manual is Edition A2010, printed in 2009; continuity to this model year is not established. The international brochure contains provisional figures and is not substituted.
