I wonder what makes these batteries so expensive? What are they made of?
Tanstaafl (there ain't no such thing as a free lunch).
Someday GM hopes to figure out how to make a big honkin car battery, and figure out how to do it economically, and hope the whole project ends up saving more energy than it consumes, or failing in that, hope no one asks how much energy it takes to build the cars.
Its called a concept car because that sounds better than something we pulled out of our #ss and hope to someday shove up yours.

Research on battery technology never seems to get funded. Maybe this time.
Fly and rent a car when you get there is probably cost effective when the destination is over a thousand miles away.
The first copies of any sophisticated technology are exceptionally expensive. The first Z80 microprocessor cost almost $2 billion (financed by Exxon). You can have one for about $4 today. It's a matter of amortizing the R&D across a huge volume of sales.
I use off the shelf parts to build computers that go on my research railcars. The CPU board is $800. The ADC board is $750. I'm working on a replacement for measuring the bearing temperatures using a PIC microcontroller. That allows me to measure 8 bearings with a $5 chip. I'm going to replace 16 channels of the 32 channel ADC with a pair of $5 chips. 6 other channels will be replaced with a different PIC. Another $5 chip. Two of the channels require very high bandwidth sampling. Those will be replaced with a stereo ADC designed for DAT recorders with a high speed serial link to a DSP capable microcontroller. The stereo ADC is $7. I'm still collecting parts and designing the final replacement. That is how you progress from an enormously expensive lab model with off the shelf parts to a custom implementation with parts specifically aimed at the objective.
Oh goodie! It doesn't use fuel; it only uses electricity to power the wheels.
But, it uses fuel to MAKE electricity to charge the battery that supplies electricity to the motor that powers the wheels.
I'm glad they explained how it doesn't use fuel to power the wheels, but just to charge the (yet to be invented) battery that is powering the wheels.
Middle men are expensive: Engine, generator, battery, motor; vs engine, transmission. Do they make up the loss via eliminating the transmission? Regenerative braking?
Forty miles...and it is 55 miles north, or 55 miles south to the nearest "market town" that has any big stores. Nope; I'll pass.
Might be, if you don't have to drive 300 miles to get to an airport where you can get a flight, and stay overnight because all the flights leave early in the morning.
[I wonder what makes these batteries so expensive? What are they made of?]
IMHO, it's not that mysterious. The technology is new. That's why plasma TV's were outrageously expensive when they first came out (along with every other new technology). Give it time, and it will enter the mainstream, just like everything else.
Sorry, your explanation is much better. (Sheepish smile). I didn't bother to read all the posts, me bad.
Funniest, most on-target post on FR in 437 years!
Yes, it was funny as hell, but I'd wager he owns oil stock.
Assuming that they are being accurate *and* truthful, then they are incredibly stupid. Ditch the $200,000 battery. Forget the 40 miles of battery power. Now you've got a 560 mile (range) car.
All they have to do is produce a hybrid with today's technology and the stylings of that Volt concept car, and GM can get into the hybrid market in a big way. That would be a logical way to gain market share, something GM brass is apparently disdainful of doing.
I've actually gone 367 miles on a tank of gas. San Diego (Mira Mesa) to the gas station at Glendale, NV. That was in a 1994 Saturn SL2. The date was Dec 16, 2000. I was enroute to my new home in Idaho. I think it has a 16 gallon gas tank. I wouldn't drive that long without a potty/stretch break anyway. A stop at least every 250 miles is a good idea.
My wife was driving the other car and she missed the turn in North Las Vegas where we intended to get fuel/food. I was real worried that we were going to run out of gas in the middle of the cold, dark desert that night. After that near screw up, my policy is to fuel up at the next spot after 250 miles has elapsed.
Am I the only one who thinks this idea of saying a hybrid gets six thousand miles per gallon (or even more if you disconnect the gas tank and run solely on batteries)
IS A BIT MISLEADING???!!!
