and i believe i spotted something rob has in common with booyah. :lol:

You caught that too? :lol: I'm saving it for a special occasion. :devil:

for the all electric cars, what about traffic? they say it will go X miles on a charge, what if it hits heavy traffic?

i know in snow country, highways are turned into parking lots because people don't fill up, they get on the highway, run into traffic, it snows and snows while they are sitting there, traffic moves slower and slower, they can't make it to an exit for gas so they run out and so the parking lot is started.

i could see this happening with all electrics in simply heavy traffic due to rain. just one car that won't move during rush hours will cause a whole lot of trouble on the road. tow truck companies are going to love the electric car.

A strictly rechargeable car won't cut it. That is what is nice about the Volt, it has a gas motor too.

The Chevy Volt is just a Hybrid but they pretend it's an all electric vehicle.

"The fact that we are here today to debate raising America’s debt limit is a sign of leadership failure. It is a sign that the U.S. Government can’t pay its own bills. It is a sign that we now depend on ongoing financial assistance from foreign countries to finance our Government’s reckless fiscal policies."

The Chevy Volt is just a Hybrid but they pretend it's an all electric vehicle.

Businessweek describes the controversy like this:

The argument goes like this. When the Volt is driving hard, say, over 70 miles per hour or it’s climbing hills, the gasoline engine will directly power the car’s second electric motor, which then turns the wheels. This came as a surprise because GM has billed the car as an electric vehicle that uses the gasoline engine to charge the battery. The company has said that the car’s electric motors draw power straight from the battery. That gasoline engine is only there to charge the battery. GM’s engineers didn’t reveal until recently that the engine can power a secondary electric motor that turns the wheels. Critics say this new revelation makes the Volt a hybrid, because the Prius does drive in a similar way. GM counters that there is no direct mechanical linkage from the gasoline engine to the wheels. So it’s an electric vehicle.

GM opened itself up to this kind of criticism. They should have just explained how it worked in the first place. If GM had just explained in more detail how the Volt worked during the three years of hype leading up to the introduction, the technology geeks, the technology geeks, auto buff magazine writers and green commentariat would have hashed over whether it’s a hybrid or an extended-range EV and been done with it. The debate wouldn’t be making headlines a couple of weeks before GM starts selling the car. But GM was trying to distinguish the Volt from the Prius and establish a leadership position. In point of fact, the Volt is different and more advanced regardless of its label.

Q: How is the Chevy Volt different than today’s hybrids, like the Prius?

A: Today’s hybrids are called parallel hybrids. They use a small electric motor for low speed driving, but switch to a regular gas engine for acceleration and faster speed driving with the electric motor providing enhancement, hence both engines work side by side or in parallel.

The Volt is a series vehicle meaning only the electric motor powers the car at all times, the gas engine is just a generator for making electricity once the battery is depleted. A little like the Prius, the engine does help spin the wheels after the battery is depleted. GM engineers chose to do this because it improved efficiency by 10 to 15 percent.

There is a clutch between the gas engine and the drivetrain. The two statements above contradict each other.

"In standard electric-drive mode, without the range-extending engine on, the traction motor that drives the wheels is powered directly by the lithium-ion battery pack. Call this "one-motor EV mode."

The problem is that the faster the car travels, the faster that motor spins--and the less efficient it becomes at turning battery energy into torque.

So to keep the traction motor's speeds down, a clutch between the engine and the generator engages, locking the engine to the generator and contributing torque to turn the wheels directly. This lets the traction motor operate at lower speeds and higher efficiency."
