ating. Although a full electric future may still be some way off in the future, hybrid architectures are already helping OEMs take a big step in the right direction on their emissions reduction journey. Hy- brids might be well-established tech-

nologies but, as OEMs work to squeeze every drop of efficiency out of these sys- tems, their lubrication requirements are changing. In this article we look at the challenges that are arising and the op- portunities these present for lubricant marketers to create hybrid-specific en- gine oils. Before looking at the extent to which electrification is penetrating the passen- ger car vehicle market, it is important to

understand what the terms widely used in the industry by various OEMs mean, since not all vehicles carrying a hybrid logo have the same propulsion systems driving the wheels. The first graphic gives a high level overview of the differences between hybrid architectures from start/ stop, mild hybrids (MHV) and full hybrids (HEV) to plug-in hybrids (PHEV) and full battery electric (BEV).
