Fuel Economy

This follows GM's call for U.S. to mandate some zero-emissions vehicles.

It compares favorably to the most-frugal F-150, Ram 1500 engines.

It might make the diesel a hard sell.

Air quality board says automakers must still meet Obama standards.

Compromise to Trump freeze would raise standards 2 percent annually.

'It is not too late to choose a better way.'

System is a first for Ford.

Stand by for more meetings, but they hope to reach a common goal

Fuel economy and emissions tests falsified for Japanese domestic market

Consumers could pay an extra $193 billion for fuel by 2035, study suggests.

California, 18 other states and D.C. are suing

But EPA chief would be open to a deal between California, automakers.

U.S. President Donald Trump is meeting 10 major automakers at the White House on Friday to discuss the fate of landmark fuel efficiency standards and a looming confrontation with California and other major states.

Major automakers are telling the Trump administration they want to reach an agreement with California to avoid a legal battle over fuel efficiency standards, and they support continued increases in mileage standards through 2025.

California and a group of 16 other states on Tuesday challenged the Trump administration's decision to revise strict U.S. vehicle emissions and fuel efficiency rules put in place under former President Barack Obama.

Subaru has admitted that alteration of fuel-economy and emissions data took place in its Gunma and Yajima manufacturing plants between December 2012 and November 2017. Some 900 vehicles were affected by data tampering, which Subaru says was done in the vehicles' final inspections by factory-floor inspectors.

The Trump administration is likely to propose freezing fuel economy standards from 2020 through 2026, according to three people briefed on the matter, a move likely to spark a fight with California and other states backing tougher vehicle emissions rules.

Global auto supplier Robert Bosch GmbH says it has developed a new diesel-exhaust management system that can slash emissions of smog-forming gases far below strict new limits set for Europe in 2020, saving automakers from potential driving bans — and maybe saving the diesel engine itself.

A federal court in New York on Monday blocked the Trump administration's decision to delay a rule that would raise penalties for automakers who do not meet federal fuel efficiency requirements.

Ford and General Motors signed an agreement five years ago to jointly develop nine- and 10-speed automatic transmissions as a way to lower costs and achieve higher fuel economy amid tightening federal rules. But now, Ford is saying no thanks to the nine-speed box developed by its crosstown rival.
