Raser Technologies unveiled the prototype vehicle for its extended range electric vehicle yesterday morning at the SAE World Congress. Raser and development partners FEV took the iconic bad boy of the environmental movement, a Hummer H3 and merged it with a powertrain very much like what's in a Fisker Karma. This prototype electric H3 has a 2.0-liter turbocharged and direct injected EcoTec just like the Karma driving a 100 kW generator. The generator provides electricity to the batteries and the 200 kW drive motor.

Like the Karma and the Chevy Volt, the motor along with a lithium ion battery pack is the only source of propulsion to the wheels. The H3 has three lithium ion battery packs arrayed under the rear end of the vehicle. The batteries can move the Hummer for 40 miles before the range extender has to start up. Beyond that, it has a 400-mile range. Based on 60 miles of daily driving (40 miles of battery plus 20 miles of range extension) Raser estimates the H3 will get 100 mpg. Raser is talking to several automakers about applications for its ER-EV system and expects to have a deal soon. The company will build several of the trucks for Southern California Edison's test fleet in the next year and hopes to have a low volume series production program by 2011.



Raser Technologies Unveils 100+ MPG Plug-in Hybrid Hummer at the SAE World Congress in Detroit

Technology in New Electric Hummer Could Drive Bold Leap Ahead for U.S. Automakers, Making Popular Trucks & SUVs 'Greener Than a Prius'


DETROIT---Raser Technologies, Inc. (NYSE:RZ - News) today unveiled a 100+ mpg Hummer H3 powered by Raser's plug-in hybrid E-REV (Extended-Range Electric Vehicle) at the 2009 SAE International World Congress, Cobo Center, Detroit, MI.

Raser developed the 100+ mpg Electric H3 demonstration vehicle working closely with Hummer. Just one year ago at the 2008 SAE World Congress, Raser and its development partner FEV Inc., Auburn Hills, MI, a leading automotive integrator, introduced Raser's E-REV power train, similar in function to the Chevy Volt but designed for use in a variety of larger full-sized SUVs and light trucks. The vehicle was developed in association with the Plug-in Hybrid Development Consortium, co-founded by Raser along with leading electric utilities, lithium ion battery companies and other automotive technology companies.

Raser CEO Brent M. Cook said, "The technology in this electric-powered Hummer is a leap ahead for U.S. Automakers. It could make the nation's popular light trucks and SUVs greener than a Prius."

The vehicle has performed well in initial test drives and dynamometer testing conducted by FEV. Video from recent test drives of the 100+mpg H3 is available online: http://rasertech.com/hummer.

The plug-in electric Hummer H3 has a range of about 400 miles, driving its first 40 miles exclusively on batteries before turning on its combustion generator. Most vehicles drive fewer than 40 miles a day, most drivers would rarely use gas and average more than 100 mpg in gas fuel economy over time.

Raser's E-REV power train was designed for most full-sized 4WD SUVs and light trucks, which represent nearly half of the vehicles on U.S. roads today because of their versatility and wide application in fleets.

"We chose the Hummer H3 and H3T as demonstration vehicles because trucks and SUVs are the best-selling vehicles in America and can benefit the most from increased fuel economy and reduced emissions," said Cook.

The Electric Hummer H3 is propelled entirely on electricity by Raser's 200kW advanced AC induction motor connected to a 4WD transmission. A small high efficiency EcoTech engine uses Raser's 100KW electric generator to recharge the batteries while driving and provides additional electric power when needed.

"Our goal was to demonstrate that electric vehicle technology is a viable solution for a variety of vehicle platforms," said Gary Rogers, president and chief executive officer of FEV. "This full-sized SUV extended-range electric vehicle shows that fuel economy in larger vehicles does not mean sacrificing power and utility."

The Hummer H3 Extended Range Electric Vehicle is on display in FEV's booth #1425 at the Cobo Center, from April 20 through Friday, April 24.

      Well if the battery pack required to make the Volt go 40mi is $12k-$15k, the battery pack required to make a Hummer go that far would probably be $30k minimum since the Hummer is significantly heavier and draggier. I would guess $40k at least for the entire powertrain package. And don't forget electricity isn't free:)
      • 6 Years Ago
      Well those concepts are solely to pretend you are doing something.
      And concepts like this Hummer that don't use the petrol engine to power the drive train are great to present stupid fake mile ranges.
      Estimating mileage based on a cycle that doesn't use the petrol engine on 2/3rd is unbelievably barefaced.

      Besides I am quite sure that nevertheless the numbers are simply maid up. I don't believe 33mpg for a second. So they probably made that number up.

      This demo may have a point in demonstrating the amount of torque they can get out of their electric engine, but it's all lost due to their doggy milage estimate.

      WTF is up with all these new EV/ER-EV concepts that use a single electric motor and all the conventional differentials and gears?

      It would be mechanically simpler and more efficient to put a motor at each wheel, even if you mount them inboard and connect via CV axles. This eliminates weight, rotating mass, and friction from differentials/transmissions. 4 motors of 1/4 the size are not going to be that much more expensive than 1 huge motor + differentials, and 4 motors allows far superior on and off-road traction, torque vectoring, etc. and there is very little efficiency penalty going 4WD vs 2WD because there aren't differentials to create binding/friction/power-loss.
        • 6 Years Ago
        Chris M is correct.

        4 wheel motors are extremely complex to implement because all 4 must be "balanced" electronically and that requires a very complex computer system.

        Consider simply turning in a circle. The outside wheels go further than the inside wheels and the front wheels travel further than the back. In effect, each wheel travels a different distance and turn at a different rate of speed to keep up with the other wheels. Now multiply that by the different possible circle radius the vehicle can make and you can see the problem.

        Once those calculations are complete, you can start talking about uneven surfaces, hills and traction differentials. What sounds good (wheel motors) turns into a logistic and computer nightmare that could have easily been solved with std. gears which automatically have a little bit of "play" in them to absorb differences.

        One motor, one controller, one transfer case and two differentials... done! This has been perfected over the last century so there is not need to reinvent anything.

        Now we can talk about wheel motors problems controlling un-sprung weight, shock, contamination etc. Plus, the transfer case and differential are the least expensive components. Why replace them with more expensive controllers & motors? This is why auto manufacturers abandoned the wheel motor idea for now, at least until motor & controller costs come way down.

        The future? Who knows...
        • 6 Years Ago
        1 motor, 1 motor controller, differential and shafts is cheaper than 4 motors and 4 motor controllers. The difference in efficiency is insignificant.

        Of course, there might be other reasons for using 2, 3, or 4 motors. 4 independent motors could provide extraordinary traction control, very useful in snow and for off-roading, the advantage might overrule the higher price.

        I must say, if even a Hummer can be plugged, then darn near anything can! I'd love to see the performance of this kind of torque and power on a much lighter vehicle!

      What is the MPG if traveling the full 400 mile range? If it's in the upper 20's to 30's, I'll take one in Red White & Blue! Each.
      • 6 Years Ago
      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?

      So for those times when you drive more than 60 miles between recharges you get:
      60miles/100miles/gallon = 3/5 gallon for those 20 miles and 20 miles / 3/5gallon = 100miles/3gallons ~ 33mpg. Not horrible for quick trips or longer road trips, if it is reliable and not exorbitantly expensive.

      Very cool! I'd like to have this in my Silverado K1500 Pickup, but my first question is HOW MUCH? followed by my second question WHAT'S THE R.O.I. WHEN GAS IS $2.00/GAL, $3.00/gal., & $4.00/gal.?

        Gotta balance the budget somehow...lol
