Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV’s are not a new phenomenon. During the 1900’s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today. This essay examines the possible military benefits from electrical hybrid-drive. It is not however, to be seen as an assessment of whether the Swedish armed forces should procure a hybrid vehicle or not. Through a method of description this essay aims to describe advantages and disadvantages of hybrid-drive in a light IFV. The survey relies on a comparative analysis of answers given in semi-structured interviews. Each source could represent a different side in a future acquisition process. Results are presented in a table showing the advantages and the criteria pertaining to each advantage. Amongst the benefits are improved maneuverability, due to increased acceleration, and "silent" mode which improves both protection and endurance. Several benefits rely on energy storage i.e. batteries, regenerative braking is an example of this. Batteries, in turn, are marred with a variety of problems. And therefore demand improved performances and safety systems in order not be deemed as disadvantages.
