Electric Cars Go Mainstream

Shares

Even though we’ve all been hoping for flying cars for decades, we’ll have to settle for electric cars for right now. But the two newest additions to the electric car family are as cool as, if not cooler than, flying cars anyway.

The Nissan LEAF will be available for purchase in several states in December, and the Chevy Volt isn’t even on the market yet, but has already been named the “2011 Motor Trend Car of the Year.”

Both cars work a little differently.

The LEAF requires no gas and is a Zero Emissions Vehicle; it doesn’t even have a tailpipe. It has a 24 kWh lithium-ion battery, 3.3 kWh on-board charger and a 120 V portable charging cable that plugs into a Home Charging Dock.

On the other hand, the Volt uses gas to power an on-board generator that charges the battery after 25-50 miles. The battery will be fully charged in as little as four hours or as many as 10 hours, depending on climate and voltage.

With so many differences in technology and design, how can the public compare fuel economy among all these different types of vehicles?

In order for consumers to make informed comparisons among electric, gas, diesel and hybrid cars, the U.S. Environmental Protection Agency has developed the miles per gallon equivalent, or MPGe, to measure distance traveled per energy unit.

The LEAF recently received an EPA rating of 106 city and 92 highway, equaling an overall rating of 99 MPGe, taking the top spot in the midsized vehicle category for fuel efficiency and environmental benefit.

Although the Volt’s rating hasn’t been released yet, it is expected that the rating will be about the same. It can a complicated because the Volt’s energy consumption isn’t as cut and dry since it does use gas, which will decrease the miles per gallon from the high 90s to the mid or high 30s.

It is this type of complication that has spurred on the EPA and the National Highway Traffic Safety Administration to develop new fuel economy labels, which are now more informative than ever.  They estimate greenhouse gas contributions from tailpipes and annual fuel costs as well as rate models bases on combined MPGe, CO2 emissions and other air pollutants. Public comments are welcome before the labels are adopted for 2012 model year cars.

The Chevy Volt just finished up its tour of the U.S. in Chicago, but the LEAF can still be seen trucking along the interstate highways until the end of March. Its next stop is the Tempe Festival of the Arts on Dec. 3-5.
