Hydrogen-fueled internal combustion engines are the focus for a partnership among a range of Japanese makers of two- and four-wheeled vehicles.

GAC Motor joins the ranks of companies considering internal combustion hydrogen engines as part of a future CO2-cutting solution.

Gas stations, tailpipes, and internal combustion engines will soon be ushered out. Could synthetic fuels ever possibly turn the tide?

The diesel engine that Ford rolled out for 2018 on its full-size F-150 pickup has been nudged aside by the PowerBoost hybrid—and, perhaps somewhat, the all-electric Lightning.

Mazda's varied vision of the future includes EVs, hybrids, and a Skyactiv-X six—but no diesel for the U.S. We consider why that didn't work out.

Toyota sees potential in hydrogen internal-combustion engines as part of a future racing program—perhaps to boost interest in its plans for a hydrogen economy.

Porsche is among the automakers hoping to find a way to keep internal combustion alive as a niche, with a sustainable new twist at the fuel-making level.

Illegal delete kits and tampering with emissions equipment is so common that is creates more noncompliant vehicles than the VW diesel scandal, a new EPA report suggests.

CARB is offering carmakers a grace period on non-compliance or defeat devices—before higher fines and a new lab to sniff out cheats next year.

Concern over an ethanol downturn, possibly exaggerated by EVs, has both campaigns—and Congress—pandering to the Corn Belt.

Until the Jeep Wrangler 4xe plug-in hybrid arrives, the Wrangler EcoDiesel is the high-mileage off-road leader. Is it eco enough?

Tech has lagged for light-duty engines designed to use gaseous fuels, like natural gas, propane, and biogas; an EU project has aimed to address that.

At least one startup may be getting close to scaling up fuel production with carbon captured from the air. But burning the fuel would still pollute.
