One of the great hopes for a green
car is the plug-in hybrid. It’s like a regular
gas-electric hybrid, only you can plug in at
night. That charge is supposed to let most
people make a typical commute without the gas
engine. Carmakers and the government are
throwing a lot of money at the technology – GM
and Chrysler both hope to release models in the
next few years. But the cars might not deliver
what boosters promise. In the first part of
our series on saving gas, Gabriel Spitzer
reports on what new research says about plug-in
hybrids in the real world:

Ted Bohn is a researcher at Argonne National Laboratory in the Chicago
suburbs and he’s showing off his ride.

“So this a prototype, plug-in hybrid vehicle. The rear half is a 10
kilowatt-hour battery.”

It’s a modified Saturn Vue, with a big old lithium-ion battery in the rear.

That battery is like what runs your iPod – only it weighs as much as a
linebacker.

Ted Bohn: “If you actually had to drive less than 40 miles on a typical
day, you could drive the whole day without starting the engine.”

Gabriel Spitzer: “Could you drive this very vehicle 40 miles round-trip
without starting the engine?”

Ted Bohn: “Close. If you drive slowly. To be honest, 25 to 30 is what
you’ll really do – driving on a nice day downhill with a tailwind is 40,
more realistically, 25 to 30.”

The thing is, you don’t hear those little caveats from some people, like, say,
General Motors.

“You plug it in. And they expect you’ll get up to 40 miles without a drop
of gas. Wow. The Chevy Volt. I’ve heard the future, and it hums.”

That 40-mile range is based on EPA tests.

Argonne scientist Aymeric Rousseau, with backing from the government,
compared those measures to how people drive in the real world.

Based on more than 100 drivers in Kansas City, he found that 40 mile range
shrinks to about 30.

Flip on your AC, and it’s more like 20.

“People now think about, you know, your mileage may vary. Now we
have to think about, your electrical distance may vary, depending on
how you drive, and what accessories you’re using.”

Rousseau says factors like aggressive driving sap the all-electric range.

And don’t forget – we’re talking Kansas City, here.

“When we talk to people from the EPA they actually say that people in
California drive more aggressively than people in Kansas City.”

General Motors concedes the point.

Rob Peterson is a spokesman for GM.

He says driver behavior can have some affect on the all-electric range.
Though …

“I wouldn’t go as low as 28 to 32.”

He says for a reasonable driver, the Volt can still get about 40.

And how about those pedal-to-the-metal Californians? Well, he says GM
studied exactly those people.

“For 64% of the people that we tested, they would be able to finish their
day with a petroleum-free and a tailpipe-emission-free commute.”

That’s not exactly what Argonne found.

Granted, the batteries they looked at were a little smaller than the Volt’s.
Size matters when it comes to batteries.

Said Al-Hallaj teaches at the Illinois Institute of Technology.

He says carmakers could build a battery that would boost up the all-electric
range – the problem is money.

“If you’re talking about a 25% increase, you know, from 30 to 40 miles,
that could mean thousands of dollars. So that could take it out of the
price range that will make it actually practical for the industry to make
it.”

Al-Hallaj says as the technology improves, so will drivers.

People are already getting better at squeezing fuel efficiency out of their
cars.

“For the first time I see people even worried about closing the window
versus opening the window because of drag. And we’re talking about
common people here, just trying to pay attention to, if your tires are not
properly inflated, the you have prob — so people start adapt and
probably get the best out of your battery.”

So it’s not that a plug-in hybrid can’t get 40, it’s just that you need to drive
like a grandmother to do it.

But if gas prices continue to climb, we may be seeing a lot more grannies
behind the wheel.

Next spring car buyers will have
another choice if they’re looking for a
hybrid car. Lester Graham reports:

The very first electric-gas hybrid car to hit the dealership showroom was the Honda
Insight back in 2000. But the small two-seater never took off like the bigger Toyota
Prius.

Now a re-designed Insight will be on exhibit at next month’s Paris Auto Show.

Csaba Csere is the editor-in-chief of Car and Driver magazine. He says the new
Insight will seat four or five.

“The profile looks very much like the current Prius, but it’s going to be a less
expensive car. It’s probably going to start at about $19,000, still get nearly 50-miles
per gallon, and it’s going to go on sale on Earth Day next spring.”

The Honda Insight will get to the dealers’ lots more than a year before a next
generation Toyota Prius and GM’s Chevy Volt are expected to go on sale.

Power Plant Pollution From Plug-Ins?

The big automakers are working on
coming up with plug in hybrids. By the
end of 2010, G-M and Toyota plan to have
cars you can plug in to charge up batteries,
backed up with small gas powered engines.
Lester Graham reports there are concerns
about whether pollution from power plants
will be any better than pollution from tailpipes:


I was out the other day with a guy who converted his Saturn four-door into an all electric
vehicle. Did it all himself.

His name’s Bob Gurk. He’s one of a lot of people who think there’s a better way, and
they want you to see for yourself.

Bob Gurk: “Here are the keys.”

Lester Graham: “I’m drivin’?”

Guys like Bob Gurk think the big automakers should have come up with electrics and
plug-in hybrids a long time ago.

Lester Graham: “Unplug here?”

Bob Gurk: “Yeah.”

(sounds of driving)

Bob Gurk says, sure, he spent a lot converting his car to electric. And there are some
sacrifices: no air conditioning, he can only go just a little over 50 miles without a charge,
but then, he’s not paying close to four-bucks a gallon for gasoline now.

Bob Gurk: “I figure it’s about three cents a mile.”

Lester Graham: “Three cents a mile?”

Bob Gurk: “Yeah.”

Lester Graham: “As opposed to gasoline, which is?”

Bob Gurk: “Ten cents a mile, I’d say. At least.”

Some people get a little concerned about more electrics and electric-hybrids. That’s
because 50% of electric power in the U.S. comes from coal-burning power plants. And,
just about every state wants to build more power plants to meet peak demand.

A guy who’s supposed to know something about electric cars is Andy Frank. He’s at
the University of California Davis. Some call him the father of the plug-in-hybrid. Andy
Frank says we don’t use all the power that’s available right now.

“What a lot of people don’t realize is that the grid actually has excess capacity. The
reason why is there has to be enough capacity to satisfy the peak draw in the middle of
the day. But, at night everybody turns off their lights and that draw goes down to about
anywhere between a half and two-thirds of what is required during the peak of the day.”

So, the idea is you could plug in your plug-in hybrid overnight.

“And then the question is how many cars could you charge with that idle capacity on our
existing grid? About 75 to 80% of cars in our entire fleet in the U.S. could be charged
with that excess capacity that we currently have.”

That’s assuming most people would only plug in at night, during the off-peak hours. If
most of them did, that would be a lot of cars that would not be emitting pollution from the
tailpipes.

But that also means some power plants will be burning more coal at night, billowing out
pollution, including greenhouse gasses.

Dustin Dwyer reports on automotive issues for Michigan Radio and he’s covered this
issue.

“One of the benefits, the power companies will tell you, is that if you have millions of
tailpipes out there spewing emissions, it’s much more difficult to capture those emissions
or manage those emissions than it is to manage coming out of one smokestack at the
power plant.”

But, you do end up shifting some pollution upstream to the power plants. And that
would pollute rural areas more, because that’s where they build the power plants.

The experts say that’s why we ought to start building parking lots with car ports covered
in solar panels, put up more wind turbines, and find other ways to use energy better – to
power all those electric and plug-in hybrids that are coming.

The federal government and US carmakers are spending more

money on battery research for plug-in hybrid vehicles. That’s because

existing battery technology is limited. But some of the grant winners

say success won’t come easily. Chuck Quirmbach reports:

The US Advanced Battery Consortium is made up of General Motors, Chrysler and Ford.
Together with money from the Department of Energy, the consortium is handing out millions of
dollars to develop batteries for Hybrid vehicles.

Johnson Controls and a partner will develop lithium-ion batteries for plug-in hybrids.

Michael Andrew is a spokesman for Johnson Controls. He says his company has a lot of work to
do to make a battery that will go forty miles between charges.

“You’ve got to hit volume targets, weight targets, power targets, energy targets, cost targets. For
the 40 mile range application, that’s gonna be a tremendous challenge for us.”

The battery and car makers say it might take even more government support to help the US auto
industry shift away from gasoline-powered cars.

Critics say the companies should have focused sooner on fuel efficiency.

Faster Payback on Hybrids

  • High gas prices cause some hybrid vehicles to recoup prices faster (Photo by Ben VanWagoner)

Transcript

Hybrid cars are generally more expensive than their gasoline counterparts. But as Lisa Ann Pinkerton reports, high gas prices mean several hybrid models are recouping their costs faster:

Hybrid cars like the Nissan Altima and Toyota Prius take around 4 years to pay back their premium. That’s according to the automobile research firm Edmonds.com. The GMC Yukon hybrid has the shortest payback period of the SUVs – almost five years. The hybrid that comes in dead last is the Lexus 600H.

John O’Dell at Edmunds.com says the Lexus could take over 80 years to recoup its premium.

“In that case you have a v8 engine that’s hybridized you’re really using the hybrid for some additional power and performance. You’re not using it – well you are using it for a little bit of gas savings – but we compute those saving to be a mere $192 dollars a year.”

That’s compared to more than a thousand dollars a year in gas savings for the Yukon and the Prius.

A green technology popular on highways
is now ready for the waterways – just in time for
summer. Only one catch – the world’s first hybrid
recreational boat could put a hole in your wallet.
Tamara Keith reports:

The Frauscher hybrid speedboat comes from Austria with a price tag of more
than $100,000.

Ralph Silverman, president of California Chris-Craft, the US importer, admits
it’s the ultimate niche item. But he says he already has several buyers interested
in this green alternative to wasting fuel idling at the dock.

“At low speeds you run the motor completely on electric power so there’s no
fuel burn, no pollution and no noise. And once you get outside your
restricted speed zone, you click over to diesel and run it like a typical boat.”

(boat sounds)

Silverman believes this technology will eventually be applied to lower cost
boats too.

year. General Motors and Toyota have been battling
to be the first to build the next generation of hybrids.
And both say 2010 is the year it will happen. Dustin
Dwyer reports:

GM engineers and executives more or less admit that the first round of
hybrid vehicle development went to Toyota. The Prius is by far the best
selling hybrid on the road.

But GM has been racing to win the second round on hybrids.

GM CEO Rick Wagoner says his company will have a new kind of
hybrid battery, and a more powerful electric motor ready by 2010.

“And because our new system is three times more powerful, we’ll also
be able to use it in a wider range of powertrains, and that’s exactly what
we plan to do.”

Wagoner says the more powerful hybrid system will save more gas. And
applying it to more vehicles will make the system cheaper.

Toyota says it’s also working to have its next generation of hybrids ready by 2010.

Green Cars: A Tough Sell

  • Hybrid cars like this Honda Insight look good to consumers at first...until they see the price tag. (Photo courtesy of the National Park Service)

We’re hearing a lot more from automakers these days about new
technologies that will save you gas. Most of the technologies they talk about
are not in showrooms yet. So when will they be? And which technologies
will find their way to your car first? Dustin Dwyer has some answers:

We’re hearing a lot more from automakers these days about new
technologies that will save you gas. Most of the technologies they talk about
are not in showrooms yet. So when will they be? And which technologies
will find their way to your car first? Dustin Dwyer has some answers:


There is already one kind of car out there that will save you a lot of gas. You’ve heard of
it before. It’s a hybrid. And it seems like everyone says they want one. They say they do:


“I live in the world where I don’t deal with what people say they think, or what they give
to a survey. I live in the world where they write the check.”


That’s Mike Jackson. He’s the head of the country’s largest chain of car dealerships –
Autonation. Jackson is pretty much the prototypical, no-nonsense businessman. He’s also
somewhat of an unlikely environmentalist, but Jackson doesn’t have much faith in today’s
hybrids:


“70% of our customers want to talk about hybrids when they walk through the door.
They’re aware of it. They think it’s a great idea. And they’re predisposed to buy hybrids.
You then get them at the table.”


Jackson says that’s when the customer asks how much extra the hybrid costs, and how
long it takes to make that money up by saving at the pump. That’s when the deal falls
apart:


“And we have a two percent closing rate.”


Jackson says, plain and simple, most people just aren’t willing to pay the extra money to
get a hybrid. So he says to really cut gas use, the industry still needs mass market
solutions, and the first technology that he’s looking out for is something that Ford
announced earlier this year. Ford’s chief marketing guy, Jim Farley calls it Ecoboost:


“Which uses direct fuel injection and turbocharging to get big engine power and all that
low end torque we love from smaller, inherently more fuel efficient engines.”


Direct injection and turbocharging have been around,
but mostly as a way to make cars go faster. Now the idea is to use them on small engines
so that when a customer comes in and wants a big powerful engine, Ford can give them
Ecoboost, which promises the same power with 20 percent less gas, and 15 percent fewer
CO2 emissions. Ford plans to put Ecoboost in more than half a million cars per year
within the next five years.


In that same time frame, you can also expect to see more diesel engines coming out from
all the automakers. Diesel will get you better mileage, and it’s now cleaner in some ways
than gasoline. But it can create more smog-forming gases such as nitrous oxide.


Ethanol is also still out there. But at best, most people say today’s corn ethanol really
doesn’t save any fossil fuels when you look at what it takes to raise the corn. So the big
hope is cellulosic ethanol, which can be made from grasses, or even used tires.


Nobody’s found a good way to make it yet and Mike Jackson, the no-nonsense car
salesman, says he’s not holding his breath. Instead, he’s looking for the real game
changer – hybrid vehicles that can be charged through a wall socket and run on electricity
alone for miles before a gas engine has to kick in. Jackson expects those plug-in hybrids
on the road within five years:


“The cost-benefit ratio is going to be so compelling, and people are going to be so
enthralled at the idea they don’t have to go to the gas station, just go home and plug it into
the socket, this idea will win over American consumers.”


The auto companies are scrambling to make a plug in hybrid. Right now the race is
basically between General Motors and Toyota. Both say they might be able to build a
plug in hybrid by 2010.


The problem is the battery. To get the higher charge, hybrids need a new kind of battery –
something called a lithium ion battery. It’s the same kind of battery, it turns out, that’s
used in your cell phone, but there are some challenges scaling that up for an automobile.
Lithium ion batteries can overheat, and right now they’re more expensive than the
batteries in today’s hybrids.


But Bob Lutz at General Motors says you can bet those problems will be solved:


“Every manufacturer in the world is hot on the trail of lithium ion technology, and the
battery manufacturers all say it’s going to work.”


And once you have viable lithium ion batteries, you’re talking about cars that can get
more than 100 miles to the gallon or better.


Most people say the next step is hydrogen fuel cells. With the fuel cells, you put
hydrogen in, and the only thing that comes out of the tail pipe is water vapor.
Some in the industry say fuel cells could be ready for the mass market in the 2020s.
Mike Jackson isn’t so sure. He pegs the arrival of fuel cells at somewhere between not in
our lifetime and never.

efficiency in the same car. In the first of a two-part series on green cars, Sarah Hulett brings us this story about the marriage of

For a lot of people, the words “hybrid vehicle” bring to mind dinky little
commuter cars that would get creamed in the fast lane. But red-blooded
horsepower fans might soon be able to get speed, performance, and fuel
efficiency in the same car. In the first of a two-part series on green cars, Sarah Hulett brings us this story about the marriage of
mean and green:


Tougher fuel economy standards are on the horizon, and record oil prices are
already here. So it’s no surprise to hear auto executives talking up the green
virtues of their products.


(Montage:) “GM will continue to drive the development of electrically-
driven vehicles…It’s Chrysler’s mission more environmentally responsible…plug-in hybrid…Saturn has a green
heritage…more fuel efficient, more environmentally-friendly vehicles.”


But typically, performance has taken a back seat to fuel efficiency, and vice
versa.


David Cole is president of the Center for Automotive Research. He says in
the past, the auto industry has taken a bipolar view of the car-buying public:


“One pole was fun, people want to have fun in a car, and another pole was
green, and if you’re green you’re probably not going to have a lot of fun. But
I think what we’ve seen is that they’ve come together.”


(Eric Merkle:) “That was the most unusual thing I saw at this year’s auto show: a biofuel
Ferrari, a Ferrari that runs on corn.”


Erich Merkle is an auto analyst with IRN. That’s a car industry consulting
firm. Merkle is talking about the recent Detroit auto show where Ferrari
showed an F430 Spider with a biofuel engine:


“It just seems so… odd, I guess, to see a vehicle like an F430 running on
ethanol. But Ferrari’s trying to put their hat in, throw their hat into the ring
too, and trying to do their part.”


Ferrari officials say the biofuel sports car is part of the company’s effort to
cut its emissions by 40% over the next five years, and Ferrari’s not the only
luxury performance car company offering wealthy car buyers a greener
option.


Fisker Automotive has a plug-in hybrid it plans to put on the market by the
end of next year. The Karma sports car has batteries that can power the car
for 50 miles. It also has a high-performance, four-cylinder engine for
backup:


“This re-defines performance. It’s performance that doesn’t hurt the
environment.”


Vic Doolan is the former president of BMW North America, and he now sits
on the board at Fisker. He says the Karma can do zero to 60 in under six
seconds:


“The person buying this car will want to drive a nice car, want to be seen in
the right circles, but on the other hand, they want to do something that not
only feels good to drive, but feels good to the heart. It’s to my mind a car
with a conscience, and I think it’s for people with a conscience – about the
environment, at least.”


A Fisker Karma could be yours for 80,000 dollars.


But analyst Erich Merkle says he’s not overly optimistic about the greening
of the luxury, high-performance car market:


“I still don’t think it’s the customer that’s really asking for that. And the other
thing you have to ask yourself is what kind of a difference can a company
like Fisker actually make. Sure, it’s nice, it’s something to see, and
something to kind of ooh and aah over. But at the end of the day, it’s still a very,
very low-volume vehicle, if it even makes it to market.”


Fisker plans to make 16,000 of the sports cars. That’s not a lot of volume.
But the big companies are also looking to sell efficient performance vehicles
to the masses.


Chrysler design chief Trevor Creed says the company had a certain customer
in mind when it created its Dodge concept sports wagon:


“They want to be environmentally responsible, but they also have a need for
speed. We can meet all of those needs, by combining our shared electric
motor with a lightweight aluminum structure to create a future performance
vehicle like this. Ladies and gentlemen: the Dodge ZEO.”


You’re probably not going to see the electric-only ZEO in your local Dodge
dealer lot any time soon, but another big car company is making
turbocharged engines that’ll be available in some cars as soon as this year.
Ford’s EcoBoost powertrain promises 20% better fuel economy, without
sacrificing performance. So Ford says its new cars will be fast, and efficient.


And if you’re looking for a cool, green car for your mid-life crisis but the
Ferarri’s out of your reach, the sporty plug-in Chevy Volt is expected to be
available in 2010.

Car companies are making plenty of promises these days about future
cars that will save you gas. To make them happen,
automakers are counting on a new kind of battery. They’re called lithium ion
batteries. These batteries could bring about a revolution in automobiles.
In the second part of a two-part series on green cars, Dustin Dwyer reports it could take a while for the revolution to get
here:


Lithium ion sounds like a complicated term. And you don’t necessarily need to know
what it means. But it might help to know that you already use lithium ion batteries every
day:


“It’s being used now in video cameras, personal phones, it’s in iPods, it’s in a lot of small
electronics and in, of course, laptop computers.”


That’s Jim Hall. He’s a consultant to the auto industry. His company is called 2953
Analytics. Hall’s had some experience working on battery powered cars. He says lithium
ion batteries are attractive because they can store a lot more power than the batteries in
today’s hybrid vehicles, and Hall says in the race to get lithium ion batteries into cars,
there are two leading companies: General Motors and Toyota.


They have different approaches to getting the batteries ready, but they both depend on
contractors outside the company to figure out the complicated chemistry. Hall says the
problem is right now, they need a breakthrough:


“And the breakthrough could come from an entirely different source. It could be from
another company that neither company is dealing with. It could. That’s the thing with
breakthroughs. You can’t predict how and when they happen.”


As we mentioned, battery engineers have already invented ways to make lithium ion
work in small things like cell phones, laptops and power drills. But it’s not as easy to
make the batteries work for something big, like a car.


Hall says one problem is cost. Lithium ion batteries are expensive. Another problem is
heat. The more energy you store in a lithium ion battery, the better the chances that the
battery could become unstable. If it becomes too hot, the battery could explode. That’s
already been a problem in some laptops.


Bob Lutz is the Vice Chairman of General Motors. He says his company has already
solved the heat problem with lithium ion batteries by using a different chemistry than
what’s in laptops:


“We’ve cycled ’em in hot rooms, maximum discharge rate, and cut out the cooling system
to simulate a cooling system failure in the car, and we’ve had a temperature rise of maybe
eight degrees centigrade, I mean, just not enough to worry about.”


GM expects to put the batteries in test cars and start running them on roads late this
spring. The goal is a lithium ion powered hybrid car named the Chevy Volt. It will go
forty miles on battery power alone, before a gas engine has to kick in. Lutz says he has no
doubt that the Volt will be ready to go by mid-2010, but officially, GM has not
set a production date.


Toyota says it’s also shooting to have the technology ready by 2010. But no other
automaker will even mention a date for lithium ion batteries. Not Ford. Not Honda. Not
Chrysler. Chrysler President Tom Lasorda says there’s a reason for that:


“When you’re trying to predict when a technology is going to be ready for mass market,
it’s very tough. Because you don’t know what the surprises might be.”


In the next few years, you can expect auto executives to make a lot of references to
lithium ion batteries. And basically anyone you talk to in the industry says these
batteries are no doubt, the next big thing that will save you gas.


The question is when. When will lithium ion batteries actually be in your car? Maybe
2010. Maybe a lot later. No one can really say for sure.
