Let's face it, the Environmental Protection Agency's (EPA) miles-per-gallon-equivalent rating (MPGe) is a good estimate, but an estimate nonetheless. Battery-powered electric cars don't burn gasoline, so a gasoline-based rating is always going to be a theoretical exercise in energy conversion.
Still, the EPA needs some way to compare electric, hybrid, and gasoline-burning vehicles. Such ratings benefit government agencies and auto companies, as well as consumers who would otherwise struggle to compare kilowatt-hours to gallons consumed. The EPA reaches its hybrid and electric vehicle figures by running test cycles, determining how many kilowatt-hours are burned, converting it to BTU/mile, and then dividing that number by the BTUs in a gallon of gasoline. The result is the MPGe figure, which will undoubtedly be a source of technical arguments for years to come.

Regardless of EPAs calculated MPGe, the electricity used to power EVs is domestically made. This has two massive benefits - it reduces our dependence on foreign oil, improves our national security, AND creates jobs!
How do you think electricity is made here in the United States (mostly fossil fuels in case you didn't know the answer). Many people think that because it's electric that no fossil fuels are used which isn't the case.
One small EV SUV that rarely gets mentioned is the Toyota RAV4 EV.
It's not the most efficient as it is a small SUV but I still get from 2.9 to 3.1 miles per KWh. This is real driving. Southern California commuting about 33 miles each way. Driving into the foothills and back ~130 miles on one charge, in traffic and at night. Down to San Diego and around town ~120 miles before recharging overnight. Cost to recharge is $0.17 per KWh at the commercial chargers (at work, hotel in San Diego, Ikea, local Carl's Jr, etc) or as low as $0.09 at home. Cost after rebates and discounts is $30K. Lease (3yr) was no money down, unlimited miles, $440/month (with tax $480) and includes maintenance. Buy at the end of lease $19K. Plenty of power, I don't use the Sport mode to get it past ~87mph. Supposedly it will exceed 100mph but I haven't tested that. Typically only use the partial charge to preserve battery life. It uses Tesla batteries and power train so it has good battery mangement. Overall works great for me.
I didn't mention I already have 4.2KWh of solar panels on my roof. Those cost about $14K after rebates and discounts. My first year electric bill dropped $2k so they will pay off before the 10 year shortest component warranty (the inverter) is up. At the low SCE rate for EV charging I haven't calculated how long adding more panels would take to pay off.
I am happy to see the expansion of the plug in hybrid. It will allow many of us to put an electric into our mix.
I have a short commute less than 8 miles each way great but when I need to do a service call it can go to 600 miles+, beach 200, etc.. So the extended range offered when needed is great. The other option is just 2 expensive, have a commuter car (All electric) and a seperate car for when I need to go those extra miles.
I am hoping this idea expands into larger vechiles like SUV's and Trucks, Again it would allow those people who want the extra power and space sometimes to still enjoy the advantages of Electric when driving shorter commutes.
Hmm! While I get your points, I think comparing a gas guzzling heavy SUV with a leaf or other small EV is a meaningless comparison. I think the Cruze vs EV Cruze is more valid. To use your method you should also state what the savings are between a big SUV and a SMART. It may be that the SMART is cheaper than the leaf??
The end may not yet be near, but recent statements by two of the world’s biggest automakers point to the fact that the industry has begun to plan for a dramatic decline in vehicles that are powered solely by internal combustion engines.
At the recent Autodesk Accelerate event in Boston, the director of product development for a niche hypercar firm replied "no, no, no" to three answers he got for what makes a car go faster. What was the right response?
