100 MPG Hummer For Real?

I’m scratching my head trying to find out the specific details around the GM Hummer that is reportedly getting 100 mpg.  An article on ConsumerEnergyReport.com indicates that this new hybrid Hummer is the brain child of Raser technologies.  The Hummer is reportedly a plug-in type hybrid designed for daily local travel.  Basically that last part means that the numbers are slightly scued, to the tune of about 70 miles per gallon over statement.

According to information direct from Raser the Hummer is only capable of up to 33 mpg on the high way.  Now, I’m not saying that 100 mpg in the city isn’t great, but obviously to arrive at these figures there are limits that must be set and gray areas to interpret.  Does that mean that the Hummer will get infinite miles per gallon if it stays under 30mpg?  I mean, I’m not sure of any city where 30+ is the norm, but they could just as easily be talking about an island city with 15 mph speed zones.

Also reported by Raser is that the engine found in the H3 Hybrid is the strongest electric engine available in a passenger vehicle.  Raser claims teh engine found in the H3 Plug-In is 4 times more powerful than the hybrid engine found in the Toyota Prius.  According to reports it can be recharged at home, obviously from the plug-in name plate, but the cost is $.60 per equivalent gallon of gas.  Again, this information is much better than paying an alternative now $2.50 per gallon of gas, but there is still a cost to driving such a hybrid.  Where do you think most of our electricity at home comes from?  I’m willing to bet it’s not wind turbines yet, most likely coal, so saving fossil fuels has still yet to be accomplished.

It becomes pretty obvious that perhaps a vehicle the size of the Hummer is required to fit all the drive train components into the package.  There is some serious weight, size, and limitations of fitting this much technology in any lesser vehicle.  No doubt, nows the time to start buying some Raser stock though. 😉

  1. Your comment about power from coal. Cola is mined in the US not imported like oil. A study was done in WA state that an all electric fleet in the US could have 84% of their energy requirement provided by existing plants if charged at night when the power is shut down or wasted.

  2. Actually, my comment is still correct, since no matter what you are still using fossil fuels. I didn’t bring up whether it was imported or not, merely the act of burning fossil fuels. I’m assuming most of the green people in the world are wanting an ultimate goal of being completely independent of such sources, since they will eventually run out.

  3. And now for “the rest of the story…”

    How do these guys at Raser come up with their 100 MPG? Simple, they claim that if you drive 60 miles per day that the first 40 is powered by electricity and the next 20 is provided by their 33 MPG onboard engine. Therefore, only 1/3 of the distance traveled was provided by gas at 33 MPG, so it’s as though you got the equivalent of 3 times 33 MPG, which equals 100 MPG.

    Now let’s see what Raser isn’t telling you. First, their 200KW electric motor costs MONEY to operate! How much, you ask? Easy. If you drive 40 miles on electric power — half in the city and half on the freeway — you will spend about 1 hour driving (20 miles @ 30 MPH = 40 minutes, plus 20 miles @ 60 MPH = 20 minutes). Raser’s 200KW motor is rated at 100KW continuous, so 1 hour of driving will likely consume roughly 100KWH worth of electricity (100KW times 1 hour). The average cost of electricity in the U.S. is 11.5 cents/KWH; therefore 100KWH costs you $11.50, got it? That’s eleven dollars and fifty cents to go forty miles!!! Luckily, you get to go the next 20 miles on good old gasoline @ roughly 33 MPG, which would consume 6/10ths of a gallon of gas if the gas engine powered the vehicle directly. Unfortunately, it first has to power a generator, which then charges batteries, which then powers the electric motor. Still, lets be generous and assume that this gas engine takes you 20 miles on 2/3 of a gallon of gas, which costs $1.67 (2/3 times $2.50).

    So the grand total to travel 60 miles in Raser’s shiny EREV (Extended Range Electric Vehicle) only cost you $13.17!!! Isn’t that great? Of course, you would’ve only spent $5.00 if you could’ve driven all of that distance powered by their good gas-mileage IC engine. Or you could’ve paid $7.50 in any vehicle that averaged 20 MPG. However, where’s the fun in that? Look, you’re driving a high tech “EREV”… ooooh! One that cost you an extra $25K, and that added an extra 1,000 pounds of weight to the vehicle. Nice extras, huh?? BTW, did I forget to mention that their 100KW motor only provides 134HP in continuous mode? But wait you say, it gives 268HP at peak operation. Yes, that’s about what the new Ford Taurus provides (except for the Ford Taurus SHO, which gives 350HP). So you’ll be riding around in your new EREV Hummer in a reduced 134-268HP powertrain… can you say “put, put, put”?

    Does anyone see anything wrong with this?? Now do you see why Raser omitted mentioning the cost of electricity and only focused on their fuzzy-math MPG gas equivalent calculation? In reality, at today’s prices, their Hummer only got the equivalent of 11.4 MPG ($13.17 divided by $2.5/gallon = 5.27 gallons, and 60 miles/5.27 gallons = 11.4 MPG)!!!!!!!!

    The fact is that electric vehicles have NOTHING to offer in solving America’s transportation needs. They are not cost-efficient nor are they technologically superior. The demand for electricity in the U.S. is expected to grow by a taxing 25% over the next decade. Raser’s Hummer draws 100KWH of electricity in order to travel it’s first 40 miles, which is well over 3 times the power that your house draws in a complete day! Talk about an instant energy crisis! It’s a good thing that battery technology is still limited and that they added an IC engine to extend the range, otherwise their Hummer would’ve used 150KWH of electricity, or more than 5 times the daily draw of an average home!!

    This conveniently omitted information might explain why Raser has also entered the geothermal power market… they realize that switching to EV’s would require well over a 300% + increase to America’s annual electric power consumption.

    My question is this, why couldn’t Raser be upfront and honest with us about the true costs of Electric Vehicles? Afterall, consumers have shown that they are willing to pay more for efficient green power.

    Could their hesitancy in telling us the whole story be due to the fact that EV’s are neither cost-efficient nor green compared to standard IC engine technology?

  4. Wow, thanks for the great comment Dennis!

    This is kind of what I’ve touched on in my other posts, it’s just not being honest. 100mpg is such a relative figure, depending on how they figure gas mileage and it’s not done in the traditional sense that everyone is used to.

  5. electric motors would sometimes overheat if they are not properly ventilated:’,

  6. No question this sounds like a huge automobile. But what’s the label price? My guess is something over $60K would be a non-runner. This is not meant to be a political comment but the ones that can pay for it could care less about a good mpg or the atmosphere. I got nothing beside being rich but please you fooling no one have a Prius parked in the driveway of a big power sucking home ala Al Gore. I know. He changed a lot of his renewable. I don’t care.
