Alt Fuels

The American diesel mainstay is focusing on hydrogen but not entirely on fuel cells.

Porsche sees e-fuels as a way to displace the use of conventional gasoline during the electric transition.

In a world of stricter emission rules, Ferrari may turn to carbon-neutral alternatives to gasoline to help keep its ICE cars on the road.

Smaller engines to be used in hybrids are a core element of the plan, which may influence Subaru's next Crosstrek Hybrid.

Volvo, which hasn't for decades sold diesels in the U.S., says that the majority of its sales in Europe are now made up of EVs and plug-in hybrids.

Under a current policy push to get more ethanol into pump gasoline, fuel prices will go up, according to findings for a fossil-fuel refining trade group.

It claims performance of the Corolla Cross H2 Concept is close to that of gasoline engines, while refueling time has been cut to a minute and a half.

A proposal from the EPA for 2023-2025 may result in wider production and use of ethanol, but it also may help utilities produce cleaner energy for EVs.

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.

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.

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

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.

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.

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.
