An investment in synthetic fuel production facilities will give Porsche a long-term stake in the fuel, with near-term plans to use it in heritage models and racing.

A study funded in part by the U.S. DOE found that ethanol is at least 24% more carbon-intensive than gasoline. It contradicts the conclusions of a 2019 USDA study suggesting ethanol has GHG benefits.

Smog-forming emissions might not be any better with synthetic fuels, according to testing commissioned by a European environmental group.

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

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

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.

Keeping internal combustion alive through synthetic fuels with a lower carbon footprint is not a better solution than batteries, T&E argues.

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.

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.

Will the corn ethanol industry survive a year when refiners are holding back and gasoline pump prices drop as low as $1 a gallon?

With the addition of an EcoDiesel V-6 engine achieving an EPA 29 mpg highway, the Jeep Wrangler is no longer a gas-guzzler.
