The equivalent EPA adjusted efficiency (the kind used for official efficiency ratings and shown on the window stickers of market vehicles) is 2.06 L-equivalent per 100 km, 48.5 km/L-equivalent, or 114 miles per U.S. gallon-equivalent. Resimulation in 2004 with a gasoline hybrid-electric powertrain as efficient as that of the 2004 Toyota Prius, and conservatively adjusted to all-wheel-drive operation like the fuel-cell version, yields simulated EPA adjusted efficiency of 3.56 L/100 km, 28.1 km/L, or 66 miles per U.S. gallon. p. 397, col. 2, line 5: for 8.6 read 6. p. 401, col. 2, lines 3-6: the Lovins et al. 2002 reference Small Is Profitable can be obtained at least cost via www.smallisprofitable.org. p. 401, col. 2, lines 7-10: the Lovins et al. 2004 reference should read: Lovins, A.B., Datta, E.K., Bustnes, O.-E., Koomey, J.G., & Glasgow, N.
