Alt Fuels

Researchers found that coffee-fed algae generated "enhanced biodiesel that produces minimal emissions and good engine performance." And it might be easier to commercialize than some other means of feedstock production.

At the center of the controversy are 2014-2016 Jeep Grand Cherokee and Ram 1500 models with the 3.0-liter turbodiesel V-6, badged EcoDiesel.

Ethanol interests have claimed that they can cut pump gasoline prices by 30 cents a gallon with changes to the Renewable Fuel Standard. Now President Biden is reportedly allowing more E15 at the pump.

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.

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?

Mercedes and parent company Daimler AG will pay $1.5 billion in penalties, as it continues to priorities Europe over the U.S. for cleaner EVs.

Through BMW i Ventures, the automaker is putting its brand behind gasoline that might help lower emissions versus fossil-fuel sources.

The House version of the new transportation infrastructure bill incorporates some of the spirit of the Green New Deal.

McLaren is planning to give synthetic fuels another try, although it knows that they won't replace battery-electric technology at this point.
