Considering buying a hybrid? Here's what you need to know. (http://www.star-telegram.com/408/story/518809.html)

Are you wondering whether your next car or SUV should be a hybrid? With more makes and models to choose from, many consumers might be ready to take the plunge. But they may also have some basic questions about how hybrid technology works. This should help.

What is a hybrid auto?

The most commonly used and commercialized hybrid automobile combines an electrically powered motor with a conventional gasoline engine. According to Tim Maxwell, professor of mechanical engineering and co-head of the advanced vehicle engineering lab at Texas Tech University, a simple hybrid technology was first developed for use in only a handful of cars, in the early 1900s, when gasoline engines were not able to generate enough power on their own. By 1915, gasoline engines were powerful enough that it was easier to build cars without the complicated hybrid technology

How does a hybrid work?

Hybrid technology uses the car's electric motor - powered by a battery pack - to run the vehicle for short periods of time, at low driving speeds commonly used in congested, city driving. Standing in bumper-to-bumper traffic or stopped at a light or stop sign, a hybrid vehicle can shut down its gas engine and rely solely on its electric motor. Once a driver hits the accelerator, the hybrid will use the electric motor in low-speed, city driving, and the gas engine will kick in at higher speeds.

The battery pack and other hybrid components come with an eight-year, or 80,000- to 100,000-mile manufacturer's warranty. Replacing an entire battery pack would cost $5,000-$10,000, depending on the vehicle.
Good data points, instead of Fear/Uncertainty/Doubt.

Most hybrid-car experts say one is unlikely to recoup through gas savings that initial extra cost of the hybrid over the course of an average, five-year ownership of the vehicle. Frank Markus, technical director of Motor Trend magazine, says that an owner may have to drive a hybrid at least 100,000 miles to offset the initial extra cost for the technology. Hybrids, however, are eco-friendly, which is why many people are drawn to them.
Hrmm... average 5-year ownership?

Let's see about the 100,000 miles claim. Comparing Camry LE to Camry Hybrid (http://www.cleanmpg.com/forums/showthread.php?t=3047). $2,332 price difference, when optioned for similar features. With 2008 epa numbers of 34 and 25, and $3.00 gas, you break even in

1/25*3.00 = $0.12 / mile
1/34*3.00 = $0.088... / mile
for a difference of 3.1765 cents a mile
$2332 / .031765 = 73,414 miles. So he exaggerates a bit.

Also, the cost of increased resale value of a hybrid should be factored into the equation.

Good point! Similar to the current premium on used TDI's.

A guy at work put on a very sobering and persuasive presentation on Peak Oil.

I told the crowd that if they wanted to look at a Prius, I would show them mine, parked outside. I did get several takers.

The local price of gasoline is now $3.40/gallon.

The price of gasoline here is now $3.40/gallon. For any meaningful comparison, you would have to look at the expected price of gasoline over the next five years, which would be more like $5.00/gallon here. It might average $6.00/gallon over the next five years, or more.

Also, with a Prius, you are working with much higher mpg's which makes the math work out that much better, and sooner!

Now for the fun part. If Joe Nascar says "Yeah, but Hybrids don't really get them numbers" just scale all MPG down by 20%

With the figures of 20 MPG for a Camry and 27 for a TCH they even out much earlier. Specifically at between 58,000 and 59,000 miles.

Now the fact that Joe Nascar usually only keeps a car for 30,000 miles is another problem all together, but that is for another thread.
