Transonic Looking at Final Funding Round This Year, Production Deployment of Supercritical Fuel System in 2014; 50-75% Improvement in Engine Fuel Economy

Green Car Congress

The use of a supercritical fuel charge enables very fast and complete combustion with minimized thermal losses. The company currently is optimizing the system for use in modern high-compression diesel architecture engines, near-term running on gasoline while longer-term utilizing advanced low-carbon fuels.

Chrysler and EPA to partner on hydraulic series hybrid powertrain for light duty vehicles

Green Car Congress

The technology has shown substantial increases in fuel economy when compared with traditional powertrains in the same type of vehicles. Acting as a pump, the hydraulic drive is used to re-pressurize hydraulic fluid by using the vehicle’s momentum, thereby converting kinetic energy into potential energy. Earlier post.)

Eaton Highlights Range of New Products to Reduce Fuel Consumption and Emissions

Green Car Congress

The all-new electronic limited slip differential, Ultra Posi is designed for front and rear-wheel drive vehicles, performs comparably to four-wheel-drive and all-wheel-drive systems and provides up to a 10% savings in fuel economy, Eaton says. We’re focused on the customers’ most critical issue—smaller packaging.

National Research Council Study Finds That Available Technologies Can Result in Significant Fuel Savings for Passenger Vehicles Over the Next 15 Years, But at Higher Purchase Prices for Consumers

Green Car Congress

Estimated price increases are based on current economic conditions and the concept of “incremental retail price equivalent (RPE) cost,” which represents the average additional price consumers would pay for a fuel economy technology. In contrast, fuel economy measures how far a vehicle will travel with a gallon of fuel.

Inaugural Quadrennial Technology Review report concludes DOE is underinvested in transport; greatest efforts to go to electrification

Green Car Congress

DOE recognizes that technology developments can help make vehicles more efficient and alternative fuels more economic, but the deployment of any technologies it helps develop is largely determined by policies, such as Corporate Average Fuel Economy standards. Impartial DOE research can help inform these standards.
