Five Kg Of Hydrogen And 300-Mile Range Leads To Simple Outcome, We Think

Toyota isn't talking about the Mirai's fuel economy just yet, but that doesn't mean we can't make an educated guess. And we do so by looking at the competition and knowing that the DOE says that "One kg of hydrogen is roughly equivalent to one gallon of gasoline."

Puts It At Top Of Compact Class, But Less Efficient Than BMW i3 Or Spark EV

The e-Golf has official EPA ratings of 126 MPGe (city) and 105 (hwy).

Confusion May Reign

Plug-in vehicle makers are losing out on sales dollars because the mileage ratings don't make a lot of sense. That's what one Venture Beat writer says after buying a Toyota Prius Plug-in and trying to apply the miles per gallon equivalent (MPGe) standard to real-world results. In short, it's difficult to do.

Groups call for MPG clarity in advertising

Google Street View is looking for gas leaks. Natural gas leaks are not only extremely dangerous, they're a terrible waste of resources and, as a greenhouse gas, a threat to the environment. Unfortunately, with the decaying infrastructure in many of America's older cities, they're pretty common, too. That's why Google is teaming up with the Environmental Defense Fund to map gas leaks. With sensors attached to the Street View cars, they are sniffing out methane leaks and documenting them. So far,

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog.

The numbers haven't made their digital way to the EPA's website yet, but we can now confirm that the BMW i3 with range extender will be officially rated at a combined 117 MPGe with 39 mpg once the battery runs out. That puts the amazing little city car just ahead of the pure-electric Fiat 500e (116 MPGE, combined) and behind the Honda Fit EV (118) and the Chevy Spark EV (119). In the plug-in hybrid category, it's at the top of the class, beating out the Honda Accord PHEV, which is rated at 115 M

If you don't look too closely at the spec sheet (available here), it appears that KLD Energy is ready to release a small, highway speed EV for under $10,000. But then you notice that the $9,800 price is just for the "system," which here means the battery, motor, controller and charger. That's the cost to put the KLD powertrain into a small, four-wheel passenger vehicle, which no one has done yet but there are talks that may see that happen.

The Ford Fusion Energi plug-in hybrid has had a charmed life so far. Qualifying for California HOV lane status and getting impressive range and miles per gallon equivalent numbers are all bound to help its market image. Now, the 2013 Ford Fusion Energi has earned a five-star Overall Vehicle Score, the highest possible, from the National Highway Traffic Safety Administration (NHTSA).

The news keeps getting better for Nissan and its efforts to boost sales of its all-electric Leaf: the Environmental Protection Agency (EPA) ahs confirmed that the EV's range is about 15 percent better than it used to be.

It's getting harder and harder to be the first/best/most electric vehicle in the US market. Most range goes to the Tesla Model S. First all-electric of the current generation goes to the Nissan Leaf or the Tesla Roadster, depending on your viewpoint. Best? Well, that's in the eye of the beholder, isn't it?

The all-electric 2013 Fiat 500e probably won't turn a profit, but that doesn't mean Fiat and Chrysler engineers haven't done a good job ramping up the hatchback's fuel economy numbers. Chrysler has just announced that the little EV has been rated at 116 Miles Per Gallon Equivalent (MPGe) combined. The EV will get 122 MPGe in the city, and highway efficiency is rated at 108 MPGe. As for range – which of course varies greatly in the real world – the official number is an impressive 87

When Ford unveiled the 2013 Fusion Energi Plug-In Hybrid at the Detroit Auto Show earlier this year, it said it expected the car to get "up to 100 mpge." Late yesterday, Ford announced that official EPA rating is actually 108 MPGe in the city, which makes the Fusion Energi, "America's most fuel-efficient sedan." The Fusion Energi also gets 92 MPGe on the highway, for a combined rating of 100 MPGe.

Spend a princely sum on a top-of-the-line Tesla Model S, which has an 85-kWh battery pack, and you can get an EPA-certified 265 miles on a full charge. If you opt for the lower-cost (and delayed) 60-kWh version, the EPA has now calculated you'll get 208 miles.

Well, this certainly isn't going to end the way Ford continues to compare its C-Max Energi plug-in hybrid to its competition from the Toyota Prius family. Beating earlier expectations that it would be rated at 95 MPGe (but meeting even earlier expectations), Ford has announced that the Energi has been rated at 100 MPGe combined (that's 108 city, 92 on the highway). Yes, that makes it "America's most fuel-efficient plug-in hybrid," as Ford so proudly states in a new press release, available below

The most interesting numbers for the 2014 Honda Accord Plug-In Hybrid – official EPA fuel economy numbers and miles per gallon equivalent – are not yet available, but we did get a few more details on the corded version of Honda's mass-market sedan that should pique people's interests. Specifically, that the 6.7-kWh battery pack offers somewhere between 10 and 15 miles of all-electric range and can recharge in under an hour from a Level 2 charger, less than three hours from a 120-volt

Ford's marketing strategy for its plug-in vehicles is coming into Focus (pun intended): compare, compare, compare.

Tesla's long awaited Model S has finally been EPA tested and it appears all those 'pie in the sky' range claims have been validated. The EPA's new test for EVs--more stringent than before--has pegged the top-end, 85 kWh battery Model S to have a range of 265 miles. Not bad.

The numbers are in, and they're looking good. According to the EPA, the Tesla Model S gets a miles per gallon equivalent (MPGe) rating of 89 (combined), 88 (city) and 90 (highway). MPGe is defined as the distance a vehicle would travel on the energy contained in one gallon of gasoline, though of course the Model S runs on electrons, not gas.

The numbers are in, and they're looking good. According to the EPA, the Tesla Model S gets a miles per gallon equivalent (MPGe) of 89 (combined), 88 (city) and 90 (highway). Green Car Reports says the range has been declared to be 265 miles, which beats the previous distance champion – the Tesla Roadster – by 20 miles.

And thus the mid-cycle product refresh – so common to computers and cellphones – comes around again to GM's plug-in hybrid.
