The US Environmental Protection Agency (EPA) and the US Department of Transportation (DOT) formally unveiled their joint proposal to set stronger fuel economy and greenhouse gas pollution standards for Model Year 2017-2025 passenger cars and light trucks. mpg US (5.87 L/100km) in model year 2021, and 49.6 L/100km) in model year 2025.
At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4 l/100 km) for a vehicle of that size.
While oil will remain the most widely used fuel, overall energy demand will be reshaped by a continued shift toward less-carbon-intensive energy source as well as steep improvements in energy efficiency in areas such as transportation, where the expanded use of advanced and hybrid vehicles will help push average new-car fuel economy to 48 mpg (4.9
liter, 3-cylinder design of the Pinnacle engine, as well as a downsized, turbocharged 750cc Pinnacle design. FEV investigated the impact of six fuel saving technologies: friction reduction; turbocharging; Variable Compression Ratio (VCR); Variable Cam Timing (VCT); Early Intake Valve Closure (EIVC); and downsizing. mpg US (6.3
Fans of chest-thumping V-8s may scoff at such a downsized engine, but everyone else will likely want to know how efficient it is. The 2015 Ford Mustang has attracted plenty of attention for its 2.3-liter liter turbocharged EcoBoost four-cylinder engine--and not all of it positive.
This crucial difference means the technology is perfectly suited to maintaining vehicle performance and driveability—widely recognized as a critical marketing issue for any car maker contemplating radical engine downsizing. They have also designed a 100 mpg UK (83 mpg US, 2.8 liters capacity.
liters of fuel per 100 kilometers (23 mpg US mpg). liters per 100 km (23 mpg US), the Audi S8 is significantly more fuel efficient than its competitors, according to Audi. The twin-scroll technology prevents the exhaust gas flows from influencing each other. TFSI reacts immediately to the gas pedal as a result.
The company anticipates that it will be the only gasoline-powered vehicle delivering fuel economy of 30 kilometers per liter (equivalent to 71 mpg US or 3.3 and the downsizing of the particles sprayed from the injector. L/100km) in JC08 mode. This new mini vehicle will have an entry price of less than ¥800,000 (US$10,200).
To achieve the target fuel economy improvement over the baseline V6 configuration, the team used GTDI technology for downsizing in combination with part-load lean homogeneous charge compression ignition (HCCI) operation for further fuel economy gains. FTP75 (mpg). HWY (mpg). The project team is replacing a 3.6L I4 Ecotec engine.
up to 33% increase in MPG) was achievable with an SSC engine replacing the Sentra’s engine when factoring in fuel cutoff during deceleration and idle in the model. up to 33% increase in MPG) was achievable with an SSC engine replacing the Sentra’s engine when factoring in fuel cutoff during deceleration and idle in the model.
On 15 Sep, NHTSA and the US EPA proposed a joint rulemaking on fuel economy and greenhouse gas emissions for light duty vehicles: an average new car 34.1 mpg and 250 g CO 2 /km for model year 2016. mpg if the automotive industry were to meet this CO 2 level just through fuel economy improvements.) ( Earlier post.).
Those of the "no replacement for displacement" school of thought might be thinking more about performance than they are gas mileage, but at what point does downsizing actually start to harm gas mileage, rather than help it? As carmakers strive to attain better MPG figures, many are beginning to.
Among the changes in the new Juke are a new design at the front and rear with greater emphasis on both premium refinement and sporty design cues; a new downsized 1.2-liter 1), improved low friction technologies and cooled Exhaust Gas Recirculation. Click to enlarge. l/100km (42.8 The existing 1.6

Yesterday, the US Environmental Protection Agency (EPA) and the National High Traffic Safety Administration (NHTSA) jointly established increasingly stringent greenhouse gas emission standards under the Clean Air Act for 2012 through 2016 model-year vehicles and fuel economy standards under the Corporate Average Fuel Economy program, respectively.
For instance, markets for liquefied petroleum gas (LPG) are particularly strong in Eastern Europe, Turkey, and South Korea, but relatively small elsewhere. To meet the increased fuel economy requirements for new vehicles, automakers have made major investments in engine downsizing, vehicle lightweighting, and vehicle electrification.
The new Yaris Hybrid, which is equipped with a version of the downsized hybrid powertrain featured in the Prius c/Aqua ( earlier post ), is a major step in the company’s full hybrid European roll-out strategy.

You may recall a few weeks back we reported on police forces all around the nation downsizing their vehicle fleets from big and brawny V-8 sedans to a new-generation of V-6 sedans and SUVs.
DeCicco’s analysis shows that optimizing internal combustion engines plus rising adoption of grid-free hybrids will enable new fleet fuel economy (unadjusted) to reach 52 mpg (4.52 L/100km) by 2025 and 74 mpg (3.18 Adjusted on-road fuel economy correspondingly would be 41 mpg (5.74 L/100km) and 60 mpg (3.92
Given the properties of the fuel blend, improved fuel efficiencies can be generated by several approaches, including downsizing/downspeeding; increased compression ratio; reduced enrichment; and the leveraging of improved efficiency at part load. Downsizing/downspeeding. Part-load CO 2. Volumetric fuel economy.
Plug-in hybrids dominate market penetration in 2025 under CAR scenario IV (62 mpg CAFE standard). CAR did not assume any downsizing of the vehicle sales fleet or significant reduction in performance by vehicles in any segment as a means for increasing fuel economy standards by 2025. The 47 mpg target is equivalent to a 70.9%
Downsizing is a key element of Audi’s efficiency strategy. mpg), with 127 grams of CO 2 per kilometer (204 g/mile). In addition, pressure and temperature sensors monitor the operation of the exhaust gas aftertreatment system. mpg) [provisional figures]—the best in this power-output category, according to Audi.

” The more weight we can take out of our vehicles though use of alternative materials, and other lightweighting strategies that we have, that enables us to further downsize the engine—which is the biggest lever you can pull in the vehicle. As one current example, the 2011 Ford Explorer (3.5-liter —Bill Ford Jr.
The combined National Highway Traffic Safety Administration (NHTSA) / US Environmental Protection Agency (EPA) fuel economy and greenhouse gas standards for light duty vehicles require an estimated combined average fuel economy of 34.1 mpg in model year 2025—equating to 54.5 miles per gallon in model year 2016, and 49.1
As a result, they conclude, uncertainties in the net greenhouse gas (GHG) effect of ethanol, particularly when used in a low-level blend with gasoline, are considerably larger than previously estimated.

utilizing these ideas and instructions in an attempting to enhance national security, reduce gas consumption, vehicle "emissions", your carbon footprint, or smog, you do so at your own risk & peril. However they also retain the ability to travel long distances when utilizing the existing gas or diesel refueling infrastructure.
Available all-wheel drive, its ratings of up to 51 mpg combined, and a comfortable, spacious interior make it one of the most appealing Camry sedans yet. The plug-in series hybrids would have used dramatically downsized engines—a turbo-2 for the EQS—while halving the EV battery pack. gas stations.
The Environmental Protection Agency (EPA) recently released a detailed proposal designed to strengthen greenhouse gas emissions standards for light-duty vehicles. MPG as 14 out of 20 automakers failed to meet their standards. One EV with a footprint target of 200 g/mi offsets 20 gas-guzzlers that miss their targets by 10 GPM.
