Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system.

Highlights important innovations and trends in vehicle design technology and lightweighting, many of which were not considered when the 2025 CAFE standards were finalized, but promise to be quite cost-effective.

Advances in lightweighting (mass-reduction) designs and technology have surpassed projections made for the U.S. 2025 vehicle CAFE/GHG standard. Overall, weight reduction of ~15% should be feasible by 2025, at costs about one-third of 2012 estimates.
