Thanks for this. Forgot to set my DVR!

But the street has to be pret-ty smoooth!

gah, old cartoons can be slathered in sexism.

I hate the Car Talk guys with the fury of 100 Mr. Fusions. That is all.

Awesome! You'll be able to drive it to the empty grocery store, the boarded-up bank, and the shanty-town outside the county hospital.

I'd just like to point out that when one of the car talk guys took a sledgehammer to that piece of composite, the implication that it was not damaged is very misleading. Damage to composites is much harder to determine than it is with most metals. While on metals you can see a dent from such a blow, on a composite there can be interior delaminations which act like cracks that severely decrease the strength of a part. Without analyzing the part ultrasonically afterwards, looking at it, saying "hey it only has a couple of scuff marks" and putting it back into service can be dangerous.

1) Those two guys don't look anything like I pictured them.
2) I'm struck with how much less annoying their schtick is when it's not on the radio. Tom's laugh doesn't grate on my nerves nearly as much when he's (apparently) not playing it up for the show.

I was struck by how much MORE annoying their shtick is on TV. At least on the radio you can pretend they don't look like that crazy guy at Starbucks who won't stop hitting on the young women.

As for the episode: Great great. But I'd like to talk about how awesome the future car is going to be LESS and see it MORE. Like, where can I buy one or shut up.

When gas hits $10 per gallon next year, the car of the future is suddenly going to have pedals.

So why are Li-ion batteries safe and reliable enough to be used in the Tesla car but not in the Chevy Volt? Is it just a matter of cost, or is one of those two car companies lying? (I really wish that the hosts had spent more time asking critical questions and less time fooling around.)

From what I remember, the battery system is specially designed to be non-explosive. See here. Presumably, Chevy would have to develop similar technology, which could be quite expensive, or license Tesla's technology if they ever decide to do that.

Also, best title ever.

Nah. We got time. That won't happen for at least 19 months. By then there will have been a miracle in car technology.

the issue on batteries between Tesla and Chevy(Volt) is that they are two very different battery packs that use, roughly, the same chemistry. Both battery packs must produce similar power outputs(kW) but have vastly different energy requirements(kWh or J). The tesla pack has to support a "250" mile range while the chevy volt has to support a 40 mile range. The peak power requirements of the chevy volt cells are much higher then those of the tesla.

Because the pack is so much larger on the tesla, they can get away with using relatively low power laptop batteries. To meet peak power requirements they have nearly 4000 cells in each battery pack. For the best pack life, each individual cell has to be monitored and equalized to all of the other cells. There is a reason that the Tesla battery pack costs nearly $50k. Tesla also isn't keeping cells from catching fire, they just preventing one cell from lighting up the entire 4000 cell pack.

GM not only needs a much higher power battery, but they also have real consequences if they don't make a safe, reliable, and long lasting battery pack. Tesla will just fold or say tough luck if the packs in its cars crap out after 2 years. How long do laptop batteries normally last? and that is a much more benign environment than the high power draws that are seen in an electric car.

as a rough guess, you could make today a reasonably performing(10-12s 0-60) electric honda civic equivelent with 100mi range for about 40k with li-ions, maybe 30-35k with NimH.

I watched it, but was disappointed that they didn't mention the Aptera.

It was Katherine Legge from a CART race.

I think Kubica's F1 crash was more impressive from a survival standpoint, but he was knocked out and didn't race for a few weeks afterwards, so it doesn't work quite as well for the 'and walked away' line.

Thanks for the explanation about the batteries, The Joven. Now I'm wondering why the Volt needs a higher-power battery. Is it because the Volt is heavier and also has less space for the battery pack than the Tesla?

I do not think that word means what you think it means.
posted by Eideteker at 6:19 AM on April 25, 2008

The Volt needs higher power batteries because it has less battery capacity(peak power for the entire pack is probably very similar between the two cars). It has less capacity primarily for cost. There also needs to be room to package an engine/generator and fuel tank somewhere on the vehicle.
