<jats:title>Significance</jats:title><jats:p>This paper addresses the question, “When using cellulosic biomass for vehicular transportation, which field-to-wheels pathway is more efficient: that using biofuels or that using bioelectricity?” Distinguishing features of this study relative to prior work are the consideration of technological maturity, both in fuel/electricity production and vehicular advancement, as well as the intended transportation application. Whereas prior studies have deemed bioelectricity as being the more efficient option, we find here that, for ranges characteristic of driving patterns in the United States, there is little basis to expect mature bioelectricity-powered vehicles to have greater field-to-wheels efficiency as compared with mature biofuel-powered vehicles.</jats:p>
