Reading today I came across this topic on Fuel Economy Test. Fuel economy figures produced by the government are routinely too optimistic, “tests by What Car? magazine have suggested.” - More than 60 cars were driven on a variety of roads, ranging from motorways to urban environments, rather than in a laboratory environment. In every case, the engineers driving the cars failed to achieve the fuel economy claimed by official data. The government said its tests provided an “indication” of fuel economy.
This next topic comes up quite often. When your car’s mileage doesn’t match the sticker. “Your actual mileage will vary,” – many still wonder why the performance of their cars differs so much from the estimates. Car companies often use the mileage estimates generated by the EPA for their advertising efforts, a habit that Carroll Lachnit, features editor of Edmunds.com, says should be tempered. “Car companies may be setting themselves up for criticism by using those numbers so prominently in their advertising,” Lachnit said. “Consumers seize on numbers — particularly with gas as expensive as it is.”
What does MPG really mean? Car owners often complain that they cannot match the claimed mpg figures for their car in real-life driving – and new statistics today prove that this is no illusion. Controlled tests have been conducted on more than 60 cars, measuring their ‘actual’ fuel consumption and comparing it to the official government figures. In the most extreme examples, – “the real world fuel economy is more than 35% WORSE than the official statistics” – and of the 64 cars analysed, only ONE actually exceeded its official fuel consumption figure.
Is Driving Green for the environment? America’s high-carbon electricity grid is short-circuiting efforts to give consumers climate-friendly, electric-vehicle options. Depending on where you live, generating the electricity to charge an electric car can produce more greenhouse-gas pollution than driving a fuel-efficient gasoline-powered car.
“Electric cars are much better for the climate” than the average-mileage vehicle in the U.S. But in 36 states, the hybrid electric Toyota Prius produces less greenhouse-gas pollution than the all-electric Nissan Leaf, because when you plug in a Leaf to recharge, you are tapping into electricity generated largely by burning coal and natural gas in those states. This is one of the main findings in a new report, A Roadmap to Climate-Friendly Cars, released today by Climate Central, a science and communications organization.
I hope you enjoyed this overview of how fuel efficient cars will hep us at the fuel pump of the future.
