As one example cited, the company has increased its use of high-strength steel and other lightweight materials to reduce vehicle weight, and thus improve fueleconomy, while still meeting standards for vehicle safety. Chrysler is also seeking to reduce electrical loads through application of higher efficiency fans and fuel pumps.
The project will be funded in part through an award from the US Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE) announced earlier this year ( earlier post ), as part of DOE’s H2@Scale initiative to develop affordable hydrogen production, storage, distribution and use.
unit features: An offset crankshaft that helps improve fueleconomy. Faster cylinder block warm-ups save fuel, especially in cold weather. Consumers are telling us they want to buy affordable vehicles that get many more miles per gallon. It will also play an important role in North America. —Derrick Kuzak.
Current fueleconomy policy clearly demonstrates this fact. —“The Case for Technology Neutral Public Policy in FuelEconomy Debate”. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
Ford and Toyota believe that their collaboration will allow them to bring these hybrid technologies to customers sooner and more affordably than either company could have accomplished alone. By working together, we will be able to serve our customers with the very best affordable, advanced powertrains, delivering even better fueleconomy.
The mid-mounted direct injection engine technology and wide range of fuel-saving features such as start/stop technology and ultra-low rolling resistance tires make the new Cruze up to 24% more fuel efficient than the current-generation Cruze. The engines offer peak fueleconomy of only 5.9 liters per 100 km.
When electric torque is blended with engine torque, the stored energy is used to improve fueleconomy and vehicle performance and is suited for stop-and-go applications. Lastly, Eaton will begin offering a remanufactured battery in July that will provide fleets with an aftermarket battery option at an affordable cost.
