Specifically, this study examines actual fuel economy of cars and light trucks (pickup trucks, SUVs, and vans) from 1966 through 2017. In comparison, the change between 2008 and 2017 (from 4.59 million cars and light trucks sold in the United States in 2017 accounted for only 6.9% gallons per 100 miles to 5.09 total Btu).
Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. In a real GRIDSMART system, they just send vehicle data to a controller, and it says, ‘I’ve got cars waiting, so it’s time to change the light.’
Broadly, the Ford team found that new light-duty vehicle fuel economy and CO 2 regulations in the US through 2025 and in the EU through 2020 are consistent with the CO 2 glide paths. 15 years and to facilitate comparison with regulations.… —Winkler et al.

In comparison, distance driven per person is down by 4.9% population). Several of the latter values were recently updated.) from its maximum.
Until recently, the energy intensity of domestic flying was higher than the energy intensity of driving light-duty vehicles (cars and light trucks). However, the energy intensity of flying became lower than that of long-wheel-base light-duty vehicles starting in 1995, and of short-wheel-base light-duty vehicles starting in 2005. (A
Numbers of light-duty vehicles (passenger cars and light trucks) were obtained from the Federal Highway Administration. In comparison, distance driven per person is down by 5.2% The focus is on vehicles per person, as opposed to the absolute number (which depends, in part, on the continuously increasing size of the U.S.
In light of the United States’ renewed effort to achieve a net zero carbon economy, our research team believes this critical review is a timely contribution to establishing an accurate, common understanding of the greenhouse gas profile for corn ethanol in comparison to gasoline refined from crude oil.

Background. Click to enlarge.
The aging of US household vehicles was reported across all light-duty vehicle types, in particular for pickup trucks, vans, and sport utility vehicles. By comparison, the average age of in-use cars increased, in absolute terms, from 9.5 years for other light trucks to a high of 2.4 years in 2009 to 10.3 years in 2017.
In comparison, EVs delivered as a percent of total US sales in 2021 totaled just 4%. The total number of light-duty vehicles sold cumulatively in California exceeded 1 million at the end of 2021. However, the same report finds that California is still falling behind Europe where EV sales exceeded 20%. California Gov.
Building on the success of its existing Eco-Friction pads for light vehicles ( earlier post ), the new formulations meet forthcoming environmental legislations without compromising pad performance and allow customers to satisfy all markets with a single specification. —Marcus Morbach, Development Manager, Federal-Mogul Motorparts.
And then light-weighting the entire vehicle,” Ben said. The post Tesla vs Jaguar vs Audi battery pack comparison reveals stark differences appeared first on TESLARATI. Munro added that the wiring in the I-Pace and e-tron were “not very well done” and said that wires could cause losses in electricity for vehicles.
Light-duty, short wheelbase. Light-duty, long wheelbase. Noteworthy trends are as follows: From 2009 to 2019, the average distance driven per light-duty, short-wheelbase (less than or equal to 121 inches) vehicle increased by 12% (from 10,391 miles to 11,599 miles). Percent change from 2009 to 2019. Motorcycles.

Given its high efficiency and its performance and in light of climate change, the diesel engine will remain an important technology for years to come, especially for those who travel long distances. Demand for diesel cars was particularly strong among private customers, where the share almost doubled from 15% in 2017 to 27% last year.
A comparison with the predecessor model shows that it contributes a 28% weight savings. The corresponding yield strength in the tensile test is more than 180 MPa, and for the profile alloys it is higher than 280, i.e. 320 MPa—significantly higher values than seen previously.
The data presented in these studies did not show any evidence of deterioration in engine durability or maintenance issues for E15 (or E20) in comparison to E0 and E10 (when tested). Materials compatibility testing provides no evidence that 15 vol% ethanol blends will cause increased rates of metal corrosion in comparison to 10% blends.
In other words, on an engine-load basis, heavy-duty vehicles are about 10 times better than light-duty diesels at reducing NO x. The differences are attributable in large part to differences in how light-duty and heavy-duty vehicle emissions are regulated, according to Rachel Muncrief, ICCT researcher and author of the paper.

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. A baseline CaRFG E10 (10% ethanol by volume) fuel was splash-blended with denatured ethanol to create an E15 fuel.
This increase was largely driven by an increase in emissions from fossil fuel combustion, which was a result of multiple factors, including more electricity use greater due to greater heating and cooling needs due to a colder winter and hotter summer in 2018 in comparison to 2017. Source: EPA. >.

On the other hand, neodymium magnets use neodymium, which is classified as a light rare earth among rare earths, as well as dysprosium and terbium, which are heavy rare earths whose resources are particularly limited. Along with this, the production volume of neodymium magnets used in xEV drive motors and generators is expected to increase.
Because the structure, comprising thousands of tiny triangles of matchstick-like struts, is composed mostly of empty space, it forms a mechanical “metamaterial” that combines the structural stiffness of a rubber-like polymer and the extreme lightness and low density of an aerogel. The resulting lattice has a density of 5.6
