This work presents a study of crash energy and severity in frontal offset Vehicle-To-Vehicle (VTV) crash tests. The crash energy is analyzed based on analytical formulations and empirical data. Also, the crash severity of different VTV tests is analyzed and compared with the corresponding full frontal rigid barrier test data.In this investigation, the Barrier Equivalent Velocity (BEV) concept is used to calculate the initial impact velocity of frontal offset VTV test modes such that the offset VTV tests are equivalent to full frontal impact tests in terms of crash severity. Linear spring-mass model and collinear impact assumptions are used to develop the mathematical formulation. A scale factor is introduced to account for these assumptions and the calculated initial velocity is adjusted by this scale factor.It is demonstrated that the energies due to lateral and rotational velocity components are very small in the analyzed frontal VTV tests. Hence, it is concluded that a scale factor is not needed to account for the missing lateral and rotational energy terms (computed from lateral and rotational velocity components), but this factor is required to account for the linear stiffness assumption made in the derivation of the formula.
