Some are almost unnoticeable, others make the car shudder each time they activate—but start-stop systems are here to stay. First rolled out in Europe and Asia, where crowded city driving requires cars to spend more time at a standstill, they switch off the engine when the car's not moving.

Given the current political landscape in Washington, it's not unreasonable to worry about the future of U.S. efforts to combat climate change. The Trump Administration has embarked on an explicit mission to undo all Obama Administration efforts to reduce carbon emissions. Climate-science deniers in the current administration include Trump himself... 
The auto industry tends to oppose, viscerally and viciously, all attempts to regulate any aspect of its products or business operations for any reason. With President Trump in the White House, the industry has succeeded in getting the comment period reopened for the EPA emission standards finalized ahead of schedule, covering vehicles in model... 
A common refrain among critics of current and future fuel-economy standards is that the need to comply with them produces job cuts in the auto industry.

Over the past few years, automakers have applied more technology to a wider array of cars in order to boost their efficiency to meet stricter fuel-economy standards. The most popular... 
The average fuel economy of the new cars and light trucks sold in the U.S. is appreciably higher than it was 10 years ago. The University of Michigan Transportation Research Institute has demonstrated that in its regular reports calculating new-car average fuel economy since October 2007.
