Chevy Volt Passes Safety Investigation

An anonymous reader writes "A few months ago, reports of battery fires from crash-tested Chevy Volts caused the National Highway Traffic Safety Administration to open an investigation into the type of batteries used in the Volt and other EVs. That investigation has now concluded, and the NHTSA says the cars are safe. 'The agency and General Motors Co. know of no fires in real-world crashes. GM and federal safety officials say they believe the fires were caused by coolant leaking from damaged plastic casing around the batteries after side-impact collisions. The coolant caused an electrical short, which sparked battery fires seven days to three weeks after the crashes. GM announced earlier this month that it will add steel plates to about 12,000 existing Volts to protect the batteries in the event of a crash.'"

    yeah the volt's batteries aren't safe like a big tank of hydrocarbons under your ass.

    The fires happened to crash-tested vehicles only

    Except for the reported fires????

    Thankyou, I know, your're from the government and you're here to help.

    Did you miss the part where it says "no fires in real-world crashes"?

    How about the part where it says the fires occured "seven days to three weeks after the crashes"?

    Contrast that to the very real danger of fire in gasoline powered car. Explain how this is worse, and part of some gubmint conspiracy.

    I'm not aware of any car that puts a big tank of hydrocarbons under your ass, though my old car did put one behind the passenger seat.

    The Honda Fit does. The Toyota Land Cruiser FJ40 from 1972-1979 did as well.

    So your solution to protecting the batteries are adding heavy Steel plates to the car. Which in turn adds more weight and gives less mileage. We can't find a metal that is lighter and stronger?

    They've said the additional bracket (it's a stretch to call it "steel plates" has it's not exactly armor) weighs about 3-4 pounds and will have no noticeable effect on efficiency.

    Photo of the bracket is here:

    From this excellent overview of the actual "fixes" that GM will be doing to customers that CHOOSE to bring their Volt in for it:

    Also, you might want to google "Volt high strength steel". The car has some of the highest structural rigidity in the industry. Yet another way in which the Volt is demonstrating a big leap forward in automotive technology.

    Unlike you, I own a Volt, so, unlike you, I don't need to lie about the numbers.

    It gets 25 (winter) to 46 (mild weather) miles per charge for me. When the battery runs low and the gas engine is powering the car, it delivers 38-40 MPG depending on speed. My lifetime economy (4.75 months, 4350 miles) is 255 MPG. I'd say that's pretty good, considering my Lexus was getting 19 MPG on the same commute.

    Apparently you're also not smart enough to do the math, it turns out the Volt is cheaper than the average car.

    $45.5k sticker (loaded)
    $7.5k tax credit (complain about this and I'll complain about the child deductions I'm funding with my six figure income)
    $11k gas savings (5 years, for me)
    = $27k gas vehicle equivalent (the average new car sale price in the US is ~$29k )

    If you're still not convinced the Volt is a good idea, I suggest you start reading this blog http://physics.ucsd.edu/do-the-math/

    I last put gas in my Volt on 11/20/2011 (7 gallons). I have driven 2,358 miles since then, using a total of 5.4 gallons. Mostly on freeways at speeds between 45 and 75 mph depending on traffic. There's a public charger across the street from work, which is 31 miles from my house.

    My best ever all electric range is 51.3 miles. My worst ever is 33.5.

    My engine does not turn on ever unless the temperature is below 25F or the battery is at the designed lower limit of state of charge.

    The car handles and drives wonderfully. I have, in 13,500 miles, rotated the tires. I will have to change the oil in a couple years. My lifetime average mpg is 158 mpg. Because I changed to a time of use schedule I have a lower electric bill now than I did before buying the car.

    Lions (as used in the Volt) are not destroyed if they are discharged completely.

    The Volt uses lions? My god, I can see that *would* be a problem- even if undamaged, they'll generally be very pissed off and aggressive after a crash, and therefore even more likely to bite your damn head off.

    Not that they're particularly safe in that respect even under normal use. No wonder GM went bankrupt if they were doing expensive and dangerous things like putting lions in their cars.

    It's not good for them, it reduces their lifespan.

    Having a lion in one's car is even more likely to reduce your lifespan for the reasons given above.

    I propose that it would make a *lot* more sense to use batteries to power the car instead. Preferably using Titanium-Germanium technology, or Ti-Ger for short.
