Hybrid Hummer Promises 100 per Gallon

The Hummer is the poster of excess consumption and inefficiency, but a company is converting the much-maligned into a range-extended electric good for 100 mpg and a range of 40 miles.

Technologies will unveil the H3 on Monday in Detroit. It promises a 90 mph top off-road capability and a lithium you can recharge in as little as three What s more, the company the drivetrain can be installed in other and it hopes to have 2,000 vehicles on the road by the end of next

That s a tall order, and is no shortage of companies promising us cars with miraculous economy and impressive range. But is taking a different approach. It isn t a car from scratch like Motors or Lightning Hybrids.

Instead, it s essentially cribbing the Chevrolet Volt and Fisker to convert existing vehicles off-the-shelf parts.

We ve taken the environmental offender on the road and it greener than a Prius, West, the company s vice of marketing, told Wired.com. It is incredible to see and hear a Hummer truly hums.

But why start a Hummer?

Because SUVs are but get lousy fuel economy, re great candidates for electrification, Jim Spellman, company vice Spellman came to Raser General Motors, where he on the Chevrolet Tahoe hybrid.

and trucks are the number one selling in America, he said. Unlike the which is a mild hybrid an eco-friendly SUV will get people s

Spellman says there are reasons as well: Trucks are big to package the gasoline engine, motor and lithium-ion batteries radically altering the bodywork or an all-new vehicle.


Unlike the and other hybrid cars we t have to build an entire car the battery packs, Spellman There was plenty of room in the of the Hummer to install them, and don t affect the ground clearance of the

Raser Technologies has been electric motors and developing electric plants since and Spellman says it started steel on the H3 prototype 15 months

The prototype we ll see in Detroit at the Society of Engineers World Congress on features a series-hybrid drive similar to the Voltec system in the Volt. Like the Volt, the H3 be driven solely by electricity. The the 260-horsepower 2.0-liter turbocharged used in the Pontiac Solstice drive a 100-kilowatt generator to the three lithium-ion battery

Fisker Automotive is using the engine in its Karma range-extended EV.

All the battery packs have a capacity of 40 kilowatt hours and weight of 600 pounds. Raser a recharge time of between 3 and 10 depending upon the voltage of the the batteries are plugged into.

For the of comparison, the Volt uses a pack that weighs 375 while the Tesla Roadster has a pack weighing 992 pounds.

Tying it all together is something calls the Hybrid Master which is a fancy name for the that manages the engine, motor and batteries. It was designed by a hybrid drive train firm that is working on a EV based on the Dodge Caliber. Motors provided some along the way, said GM Kyle Johnson.

We re well of this project, Johnson We helped them with of the electronics integration and did some

Getting all the hardware to fit required the Hummer s chassis. The transmission was back, the drive shafts and the exhaust re-routed. The Raser H3 has a smaller fuel tank 11 instead of 22 and it s been moved to room for the batteries, which are under the vehicle near the axle.

Despite the mods, Raser the vehicle doesn t lose any of its utility.

West says will begin soon and the hopes to have 2,000 in the form of SUVs and trucks on the by the end of 2010. He says Pacific Gas has requested two of them.

No word yet on how the will be funded or what the will cost. Raser more details when the is unveiled Monday.
