High Efficiency Hybrid Car Planned For 2009

An anonymous reader writes "You may have heard some of the hype last month when California-based Aptera let out first word of its allegedly super fuel-efficient (and cheap) Typ-1 electric vehicle. A video test drive and gee-whiz specs breakdown at the Popular Mechanics site proves that this thing is for real. The plan is to have a vehicle that goes 120 miles on a single lithium-phosphate pack charge for 2008, with a 300-mpg model to follow by 2009. Aptera is also mentioned in Wired's new cover story as one of several early front-runners for the Automotive X Prize."

In a magic future it will be generated by wind, solar, geothermal and some sort of better-thought-out nuclear like pebble-bed reactors. Right now that energy will be produced by oil/coal so yes there will be pollution.

Modern electricity generation plants ( using coal or oil ) convert quite a bit more of the chemical energy in the fuel to electricity. They're really quite good at it. They can run hot, they don't need gearboxes, etc etc. Even better, these facilities can have scrubbers and other carbon reduction measures which are too expensive for cars. Also, of the electricy consumed by an electric car, far more of it can be converted to torque simply because electric drivetrains are so simple and direct. No need for transmissions, and no need for differentials or CV joints ( provided the motor is in the wheel as some electrics do )

      So, yes, electric cars are not non-polluting. But, the amount of fuel burnt to move an electric car 100km is quite a bit less than even the best hybrid IC car can pull off.

In addition you mention 100,000 miles, but that is low. Most modern cars are good for 200,000 miles or more. There are Priuses that have over 300,000 miles on them on the road today.

      A $25,000 50 MPG Prius, run for 200,000 miles at $3 per gallon will cost you $12,000 in gas. Your $15,000 30 MPG Corolla will cost you $20,000 in gas. The Prius would cost you only a net $2,000 more in this scenario, and that does not include the unscheduled maintenance cost penalties you pay (see below).

      If gas goes to $4 per gallon it is about $17K vs. $27K, making the Prius a wash. If it goes over $4 per gallon, the Prius is cheaper.

      As hybrids become more effecient and cheaper, these numbers will dramatically swing against owning a regular car. A 300 mpg hybrid like the article mentions that costs $30,000 will only cost $2,000 to $4,000 in gas over the lifetime of the car even at $5 per gallon. Such a car is free in comparison to the cost of the Corolla. You would literally save in the low tens of thousands of dollars by buying the 'more expensive' hybrid.

      There is another big factor. Scheduled maintenance costs on hybrids are about in line with regular cars, but their unscheduled maintenance costs tend to be much lower. Cab companies and fleets like this one are starting to publish the reliability and maintenace results of using hybrids. The data is still sketchy, but even with the early hybrids (2001 models or so) that these sets of data apply to, the data indicates that you can save from $1 to $2 per 50 miles (very rough estimate) or so in unscheduled maintenance costs (ie, unexpected repair costs) over the life of the vehicle for a good hybrid vs. a regular IC vehicle. In other words, if you drive 200,000 miles you, statistically speaking, save about (200,000/50)*(1 to 2) = $4,000 to $8,000 over the lifetime of the car. Now that is a statistical average of course, and you might get a car that costs you almost nothing over that time. But that again you might not.

      Hybrids are also holding their value much better than regular cars. You don't take a huge hit to the value of a hybrid just becuase you drove it off the lot. Go look around you'll find used Priuses going for almost as much as new ones.

      Finally, I'll point out that Toyota (since we compared Corolla to Prius) no longer makes or sells regular IC cars in Japan. It's hybrid only. They are only making their older cars for America and some other markets, but they have already shown that they consider all non-hybrid lines to be end-lined soon.

      In short I would not buy a high-end new IC car today. If you're not ready for a hybrid or you don't drive enough for it to make economic sense to you, then do your best to buy a cheaper used regular car and wait. In the next few years you will see IC cars fall out of favor. For a period of time IC cars will become dirt cheap as demand for them drops through the floor, making the greatest buyers market in history for IC cars. Then IC cars will all but disappear.

For example, why do the two hybrid cars I can buy here have gasoline engines and a fuel economy comparable to a diesel in the same price class, when they could (1) burn diesel, which has a much better fuel economy _and_ is cheaper here, and (2) use the combustion engine _only_ for electricity generation, so that it can run at its optimum efficiency? And, while I'm at it, why not a more efficient engine (e.g. Sterling or Wankel instead of Otto)?

    And why do we have cars that can run on up to 85% ethanol (the rest being gasoline) instead of 100%? And why do diesel cars not run on straight vegetable oil right out of the factory, even though you can get them converted for about 2 thousand euros, after which they can run on straight vegetable oil _or_ diesel?

    Come on, people! It's not like there are unsolved technical problems here! The solutions are known, they are just not in mass-manufactured cars.

    And governments! The (well, some previous) government here has refused to lower taxes for CO2-neutral fuels because "the environmental benefits are not clear". This despite studies having found that using straight vegetable oil instead of diesel reduces CO2 emissions _even_ if fossil fuels are burnt in every possible phase of the production and transportation. If it wasn't for that, straight vegetable oil would be cheaper than diesel here.

    And all the misconceptions people have. "But electricity generation emits CO2, too!" Well, depends how you generate your electricity, don't you think? "But the crops for producing vegetable oil will use up valuable arable land!" Well, not if you use crops that don't, or algae, which grow in deserts and on salt water and have a much higher yield anyway. And on and on.

    I don't claim _I_ have all the right answers, but it's sad to see how messed up the situation is, considering the things that _are_ known and _could_ be used.

  14. on the market already by Anonymous Coward · · Score: 5, Informative

    You're behind the times. All the big fleet operators in the US are testing diesel electric hybrid trucks now(fedex,ups, coca cola, etc), and are going to be investing in them to expand their fleets as the older trucks wear out and get replaced, and two companies in england are shipping all electric trucks well into the multi ton delivery range. *Shipping*, as in normal, you can buy them right now. Cab companies all over are switching to hybrids from crown vics, and as soon as plugin hybrids start coming from the majors they will be using those. This stuff is not theoretical anymore, all these new drivetrains are hitting the market now and in 2008, the automotive industry is going through significant disruptive technology change *right now*. Over seas, in india and china, big moves to electric vehicles, several large companies shipping them in 2008. The range is plenty good enugh now, and will only get better the next few years, ton of battery breakthroughs this year, as in this car in the article, read about their battery tech. Rough analogy, electrics and hybrids are at a similar status as computers in say 92-3, and that was "good enough". Earlier adopters get the benefits, just like with computers. Heck, the prius has been out ten years now! And most of them still on the road, and most of them still running on the original battery packs!

    You'll be seeing diesel electric drivetrains in normal cars and pickups real soon now. Real soon. Suburban guys and contractors are gonna eat them things up off the lots as soon as they hit. Same power as a big gas engine, twice the mileage, same towing capacity, double duty as the home or jobsite backup generator. Americans *like* pickups and SUVs, that style is *not* going away, that's where a big part of the market is, so plugin hybrids will be coming to a lot near you soon in pickup and SUV models. It might be the japanese have them first, but who knows, detroit is getting desperate and I bet there's some skunk works action going on there. They can be motivated at times to actually produce. The shareholder pressure and market pressure is now intense, that will have an effect.

  15. lithium-ferro phosphate by raddan · · Score: 3, Informative
    Lithium-ferro phosphate is the chemistry used in the cells for the XO OLPC laptop. Here an excerpt from ACM Queue's recent inteview with OLPC CTO Mary-Lou Jepsen:

    We started to look into other battery chemistries, such as lithium-ferro phosphate, which people haven't really used yet in consumer electronics. This chemistry charges in heat up to 60 degrees C. It's also about as safe as NiMH. We can put nickel-metal hydride or lithium- ferro phosphate or, eventually, other battery chemistries into our laptops, which was another accomplishment. It was a real pain. We did that in the embedded controller. We also have a little fuel gauge in each battery that so we can keep track of its life cycle.

    Our battery has a five-year life. You can go to 2,000 charge/recharge cycles. The lithium-ion battery in my ThinkPad is supposed to last for 500 charges, but in practice it's more like 200. So, moving to lithium-ferro phosphate is really cool because you don't have to spend additional money on periodic battery replacement costs, regardless of the environment.

    Also, lithium-ferro phosphate is pretty environmen- tally friendly. Some early studies we did suggested that it possibly can decompose into fertilizer (with processing). Typically we think of batteries as environmentally bad, but there's some indication that lithium-ferro phosphate isn't that harmful. We haven't quite gone through all of the rigor on this, however, and it does require some processing to decompose it into fertilizer. Full article is here.

  17. Re:But, will it fly? - not insightful by Ralph+Spoilsport · · Score: 4, Insightful
    saboola parodied a comment about flying cars by looking at the transition from horses to automobiles with the same language.

    Somehow, he was rated insightful, when he really isn't. Flying cars and driving cars may have epistemological equivalence (both = vehicle operation) but they are not ontologically equivalent. Example: hacking up a cooked turkey and brain surgery are both examples of (episteme) knife wielding, but they are not the same (ontologue) activities and have radically different social values and results.

    Similar to the brain-dead postmodernists who insist that theory has no value, because "it's all theory".

    All he did was act contrarian in a very adolescent manner - the kind of numbskull pigheaded idiot logic I expect from a dull second year university student - the kind I normally give a C- and a recommendation to do some follow up research to get the grade up.

    What many people don't know is that the electric car actually predates gasoline and diesel vehicles, but for so[big]me rea[oil]son, disappeared into obscurity (I guess we could blame lousy battery technology, too). As recent as a decade ago, the GM EV-1 provided a viable solution to current car technology, but again, disappeared into obscurity. The story of this car can be seen in the documentary Who Killed The Electric Car? . It's a damn shame that such a solid alternative was sent to an early grave. Hopefully this time around, with the focus on global warming, car companies will get smart and embrace this technology.
