This technical brief highlights important innovations and trends in downsized and turbocharged gasoline engines, several 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.
Analyzes near-term electric vehicle trends to inform on how governments might optimally evolve their electric vehicle incentive programs to sustain market growth. Assess how electric vehicle costs are reduced in the 2020—2025 timeframe to estimate when the consumer proposition tips in favor of electric vehicles in leading markets.
Highlights developments in technologies that contribute to vehicle fuel efficiency by improving control of heat in the powertrain and the passenger cabin. Few thermal management technologies were explicitly incorporated into the technology projections for the US 2025 CAFE standards.
Identifies auto markets with highest electric vehicle shares by region in the U.S., including smaller and medium size metropolitan areas. Analyzes electric vehicle promotion actions in place that are accelerating market development in the leading markets.
