As the federal government plans to tighten emissions regulations and significantly increase CAFE standards, a new study from the Boston Consulting Group says automakers will be able to achieve these new regulations with improving gasoline engine technology. These technologies will take the pressure off automakers to move to electric vehicles. Advanced combustion technologies can cut tailpipe emissions 40 percent in new vehicles at a cost to the consumer of about $2,000 per car. The cost of these technology changes is likely to be half of what was expected three years ago.
