Today, there is no turning point of dual voltage power networks introduction in short-term high luxury vehicles seems immediate. This is the previous step to the implementation of a new high single voltage network. However, there are still some technical challenges not only to the current products and technologies used in the power distribution and control systems in vehicles but also to the whole architecture approach (safety, EMC compliance, management, system monitoring, cost ...). The aim of this paper is to present a new LEAR 42V Power Distribution Network (42V-PDN) proposal - an evolution from the first concept presented in Villach (1999) - for a 2005-2010 vehicle. This advanced concept covers most of the new technical challenges both for power busses (converters, short-circuits, arcing, jump-starting, lighting ...) and for signal busses (hierarchical busses, RF, mechatronics, ASICs, ...). When the integration in a vehicle will be completed and fully tested, pros & cons bill be pointed out.
