During the timeframe from 2012 - 2020 mass based fuel consumption and CO2 limits will be applied to all new vehicles. The weight reduction targets for the body, closures and other structural components in the vehicle can be accomplished by a combination of design optimization, material substitution, and de-contenting. The current vehicle development strategy is focused on designing lighter and cost competitive new vehicles. EDAG Inc. has carried out lightweight design studies (funded by EPA and in collaboration with FEV) on some current production vehicles. These studies included the mandate that the resulting vehicles should meet and/or exceed the regulatory crash safety and current NVH performance requirements. Combined with sub-system level optimization, Multi-Discipline-Optimization (MDO) automation was carried out with seven performance and one cost constraints.
