Comment on Vehicle Weight Reduction Target

In the opinion of this review committee, it is extremely unlikely that a 50 percent reduction in vehicle weight (at anywhere close to cost parity) can be achieved in the 2010 to 2012 time frame without increasing vehicle costs substantially. It might be prudent for FreedomCAR to reconsider this probably unattainable target and adopt a more realistic goal–for example, a 30 percent overall weight reduction with minimal (say, <5 percent) cost penalty. The overall system objectives could either directly reflect this change, or targets in other systems areas might be adjusted in compensation. The only other alternative is to maintain the current 50 percent weight saving goal but allow for a significant cost penalty—probably unacceptable to both the automotive industry and the automotive consumer.
