National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Aerodynamic Characteristics of Sixteen Electric, Hybrid, and Subcompact Vehicles. Complete Data.

DOEJPL152170T1

Publication Date	1979
Personal Author	Kurtz, D. W.
Page Count	95
Abstract	The report presents an elementary electric and hybrid vehicle aerodynamic data base and describes how it was developed. Sixteen electric, hybrid, and subcompact production vehicles were tested in the Lockheed-Georgia low-speed wind tunnel. Zero-yaw drag coefficients ranged from a high of 0.58 for a boxey delivery van and an open roadster to a low of about 0.34 for a current four-passenger prototype automobile which was designed with aerodynamics as an integrated parameter. Vehicles were tested at yaw angles up to 40 degrees and a wind weighting analysis is presented which yields a vehicle's effective drag coefficient as a function of wind velocity and driving cycle. Other parameters investigated included the effects of windows open and closed, radiators open and sealed, and pop-up headlights. Complete six-component force and moment data are presented in both tabular and graphical formats. Only limited commentary is offered since, by its very nature, a data base should consist of unrefined reference material. A justification for pursuing efficient aerodynamic design of EHVs is presented which demonstrates the partitioning of the road energy requirement and the dependence of range upon the aerodynamic drag component over an electric vehicle driving cycle. Establishing this data base is one required element of a larger task, the purpose of which is to develop an aerodynamic design guide for use by the EHV industry. (ERA citation 04:053417)
