A hybrid electric car combines an internal combustion engine with batteries and an electric motor to provide high fuel economy. Hybrids automatically switch between gas and electric to maximize efficiency. Batteries are charged by the engine and during regenerative braking.
An all-electric car is powered only by an electric motor that receives electricity by plugging into the grid. These cars consume no gasoline and produce no tailpipe emissions. However, the level of overall emissions depends on the amount of coal used to make electricity.
A diesel engine does not use a conventional spark plug to ignite the fuel like gasoline. It uses the heat of compression to ignite the fuel to begin the combustion process. Diesel combustion is a more efficient process than spark ignited combustion, so diesel vehicles produce more miles per gallon than their gasoline counterparts.
More than 95% of gasoline is blended with low-levels of domestically produced ethanol. Ethanol is currently produced from corn with future plans to manufacture it from cellulosic materials—crop wastes, grasses, etc.—once technology is commercial. When comparing E85 and gasoline, all regulated emissions either decrease or show no significant difference.
Compressed natural gas is cleaner and less expensive than gasoline, and generally comes from domestic sources. When considering the purchase of a CNG vehicle, owners should first determine whether convenient and reliable CNG fueling is available.
It’s been nearly two years since Fisker Automotive declared
bankruptcy after it sold just 1,700 cars sold. After bankruptcy, the company
was purchased by Wanxieng America, a subsidiary of the Chinese auto parts
giant, Wanxieng Group. From the start, Wanxieng made it clear that it planned
to bring the company back from the graveyard, although we’re only now getting
word on how and when that might happen.Last week, Fisker announced that it will change it...
The attendance for this year’s annual National Drive
Electric Week (NDEW) topped 130,000 people worldwide—easily beating last year’s
participation.In nearly 200 cities, curious drivers were able to learn
about plug-in electric vehicles and take test drives. The event is organized by Plug In America,
the Sierra Club, and the Electric Auto Association. The 2015 event took place from September 10 to 15.At the Los Angeles festivity, Nissan...
The Volkswagen Group announced this week that it will immediately cease sales of VW and Audi turbo diesel vehicles in the United States. The move comes in the wake of a massive scandal in which the automaker admitted to intentionally deceiving consumers and regulators about emissions from its so-called “clean diesel” lineup. The deception led to the release of tens of thousands of tons of smog-forming NOx into the atmosphere in the United States alone. Volkswagen said Tues...
Nissan announced last week that the 2016 edition of the Leaf
will offer buyers the choice to upgrade to a larger battery pack, providing
about 107 miles of driving range. The larger 30-kWh battery pack will come
standard on all SV and SL models, while the base S trim will retain the same
24-kWh hour pack found in previous models, going back to 2010.The larger pack, with its EPA-estimated range of 107 miles,
would give Nissan’s EV the longest range ...
