New X-Prize for Fuel Efficient Cars Announced

miowpurr writes "A new X-Prize for ultra fuel efficient cars has been announced. The winning car must 'carry four or more passengers and have climate control, an audio system and 10 cubic feet of cargo space. They also must have four or more wheels, hit 60 miles per hour in less than 12 seconds and have a minimum top speed of 100 miles per hour and a range of 200 miles. Those that qualify will race their vehicles in cross-country races in 2009 and 2010 that will combine speed, distance, urban driving and overall performance.'"

Less exciting

[philspear]

This is just not as exciting as the other X-prizes. Maybe more valuable, but still. Just saying.

More practical than other X prizes

[Colonel Korn]

Sure, it's less exciting on a sci-fi-this-is-awesome level, but it seems to me like the most practical of the X prizes. This is the first that could very conceivably have a massive effect on worldwide transportation and even politics and the global economy in the next decade. What other x prize is tied so closely to the major environmental concerns of the day?

Maybe fewer people will follow the prize closely, but I suspect that more will follow its aftermath.

Re:

I guess that would depend on what you consider a major environmental concern. Getting as many people off my planet is the top of my list. ;)

Re:

[diGitalRchitect]

I don't think there is much likelihood that this prize will have any major impact on an environmental level. Addressing fuel economy globally is not at all about creating the most efficient technology. It will be about creating the most mass producible solution. The best solution will be the one that relies on the most abundant resources.

We see contention now in the number of hybrid electric vehicles that can be produced, because they all depend on a limited supply of some common parts. The more Prius vehi

Re:

Doesn't the Tesla run on something like 100 laptop batteries. That means that for each one, 100 fewer laptops can be produced.

It's impossible to manufacture more batteries?

One factory produces seemless containment units for nuclear reactors. They produce 8 a year. That means that only 8 reactors based on that technology can be opened each year.

Yes but if we also build two seamless containment unit factories per year, we can build 24 reactors the next year, 40 reactors the year after that, and 56 reactors the year after that. Sorry, this is one game of Starcraft that you're gonna lose playing that way.

Wow. You know absolutely NOTHING about economics, do you? In centrally-controlled societies like the socialists used to ask for (until they found out they don't work) the planners would simply ask for more seamless containment units to be built. In free market societies, factories which produce seamless containment units which are suddenly in much greater demand get to charge a much higher price. This is acceptable because the people who built such factories as exist planned well, and deserve their prof

Re:

One reason why it's not exciting is that a number of outfits already have qualifying vehicles. That makes this more of an announcement of a Green Car Race two years in advance than throwing down the technology gauntlet and challenging teams to come up with something genuinely ground-breaking. Just as one example, Tesla Motors (www.teslamotors.com) plans to have a car substantially superior to the specs mentioned in this X-Prize in production by 2010: the WhiteStar.

Re:Less exciting

[jandrese]

I thought the Tesla Motors cars were all electric? How do you intend to go cross country with an all electric car? I don't think the rules will allow for you to chase it with a big generator truck to recharge the car every 200 miles. The way the rules are written, it sounds to me like your car is pretty much going to have to be gasoline or diesel powered because that's the only way you're going to be able to refuel it when you're 1000 miles from home. Sneaking in behind shopping malls or something every 200 miles and plugging it into an outside wall outlet is probably not going to work.

I'm not sure what point a nonstop race proves. How often do people drive 3000 miles without stopping any longer than to refuel? Maybe truck drivers, but the race's vehicle specs didn't sound much like a semi's to me. Plus, I didn't see anything in the specs about the car requiring its own toilet facilities. Or maybe it'll just be astronauts in diapers driving?

Re:

Read the rest of my post. While there is an electrical infrastructure in the US, there's not (yet) a system of stations where you can pay to recharge an electrical car. You will forever be driving into a store or something and asking the shopkeeper if you can plug into an outlet. It's just not very practical.

You could make the engine part a trailer [dansdata.com]. When you're doing your inter-city commutes, you'd just plug it in at work, plut it in at home, and go about your merry little business as a fully electric car.

When you want to go cross-country, you'd hook up the trailer to the car, and as necessary, it starts up, generates power for the battery, and shuts down, like hybrid cars. Except unlike hybrids, you're not carrying the whole engine and supporting systems (gas, cooling, exhaust, etc) with you everywhere you go. And like hybrids, it can work the engine where its most efficient. (The ICE is so inefficient, that it's way more efficient to use its mechanical power to generate electricity, and then use the electricity to move a vehicle - see the popular diesel-electic train).

Heck, if there's a standard for wiring up these trailers and cars together, a whole new industry is born - car companies can produce an all electric car and their standard trailer, and third parties can make their own trailers. Or rent a trailer if they don't go on long trips frequently enough to justify owning one (aren't most cars just used for the daily commute? In which case the plug in at office/home would work just fine).

Also not mentioned...10Mil prize. Not bad at all, though I suspect that if a car that efficient could be designed for that price, it probably already would exist. Also, the prize is split between "mainstream" and "alternative" cars. The above restriction was for the mainstream category, which I imagine will be acheived later.

To put the prize money in perspective, automakers typically spend hundreds of millions developing a new car, and probably expect to gain more than 10 million in profits.

Fuel Restrictions?

[ryanguill]

I think this is great and is going to have a lot more impact on our daily lives than the space prize. It does seem like quite a challenge though. Are there any restrictions on the type of fuel though? Does it have to use regular gas? Can it use anything that can be measured in gallons?

Re:

[truthsearch]

I imagine it must be regular gas. The car must be production-ready and "consumer friendly." It's also race cross-country, so refueling with anything but regular gas every few hundred miles would be quite a hassle.

MPG?

[truthsearch]

My car does that now. The summary left out the most important piece of information: the car must get 100 MPG or more.

technology advances

[phoenixwade]

I think battery technology is advancing fast enough to make the listed criteria too easily attainable by 2010 or 2011. Why not make the requirements difficult so as to promote some really groundbreaking new technology. The criteria as set is essentially the same as needed for a comercially viable pure electric (assuming the price is competitive too....) I think that an "X" prize should be at the very limits of technology, this one is more of a "P" prize.

No Batteries Allowed

[Colonel Korn]

I had the same reaction when I read the summary, but on reading the article it sounds like the car is required to use gasoline. If not, how would they convert their 100 mpg requirement into electric-car terms? I can imagine several possibilities, but none seem really neutral.

It's not really fair (or in the spirit of the competition) to disallow electric cars, but it's not fair to say they get infinite mpg, either. Do we measure their cost in electricity, or in fossil fuel burning to generate that power?

Re:

California, at least, has a law that requires you to merge with freeway traffic at something similar to freeway speeds. In the space of a freeway on-ramp, you should be able to accelerate to ~60 mph. Otherwise, you cause traffic and safety issues for other drivers.

Re:

Re:realistic specs??

[dmatos]

Acceleration like that is required for safe merging onto a highway that's traveling at 60MPH. Assuming linear acceleration from zero to sixty (which is probably an optimistic assumption), say you get on the highway on-ramp at 30, and have to accelerate up to 60 to merge. You'd need 6 seconds to do that. How far would you travel in those 6 seconds?

0.2 miles

And if you used 10 seconds to do that (0-60 in 20 seconds)?

0.5 miles

How long are the on-ramps where you live?

As for the top speed, that's what you'd get to after holding down the accelerator on a flat, straight stretch of the road for 2-3 minutes. Reasonable traveling speed for a vehicle is always some amount below the maximum speed of that vehicle.

Re:

[Christianfreak]

Because a car for the mainstream must be able to use freeways. 15-20 seconds is TOO SLOW and risk accidents as you try to merge. I have no love for idiots who do 30 on the on-ramp when traffic is moving at 70+.

I live in Dallas. The speed-limit of 60 on the freeways is meaningless. Unless there is a traffic jam people are going 70+ in the slow lane. Most large cities are the same way.

Must meet US safety regulations
Must have features considered standard in today's automobiles at a cost that is not prohibitively expensive, and must provide a business case proving so.

water 4 gas

[xj]

Well conservation of energy for one. The energy required to split water in to hydrogen and oxygen is greater than the energy you get from burning it otherwise we'd all have perpetual motion machines running in our back yard.

Flow rate.
Say an engine has a displacement of 3 liters and is operating at 2000 rpm.
3 liters * 2000 rpm /2 (as this is a 4 stroke engine) * .85 (assume this is not turbo charged so the cylinder is never completely full) = 2550 liters of air per min.

the electric power required to electrolyze the hydrogen equivalent to 1 gallon of gasoline is equal to (500 moles) x (0.06587 kWh/mole) = 32.935 kWh, and the approximate cost of that power = (32.935 kWh)
credit to this site http://www.stardrivedevice.com/electrolysis.html [stardrivedevice.com]

How much current can you alternator put out? Maybe 100 amps. How much hydrogen could your car generate per min? How much power can your alternator produce 100A *13.7V 1.37 KW

How much hydrogen could your car produce per min?
1.37 * (.06587 kWh/mole) / 60min/hr * 22.4 liters/mol = 0.033 liters of hydrogen per min
Compare this to the number above for the volume of air entering the engine.

How much hydrogen would one need to run a vehicle?

If 500 mol of hydrogen = 1 gallon of gasoline
If the vehicle gets 30 mpg at 60 mph = 2 gallons of gasoline per hr or 1000 mol of hydrogen per hr * 22.4 liters / mol / 60 min / hr = 373 lites per min of hydrogen

Compare this to the number above.
If anything all those hydrogen generator scams are going to do is create a vacuum leak that will turn on your check engine light.

Safety standards?

[hernick]

I wonder, must the winner meet recognized safety standards to win the prize? It's considerably easier to design a vehicle that won't ever come close to government crash standards and thus couldn't possibly be licensed as a car...

Doesn't the free market already offer this?

[edmicman]

I don't get it....wouldn't the market dictate progress for massive fuel efficiency gains? Do you think if people were honest-to-goodness clamoring for 200mpg alternative vehicles, the companies would already be doing it? I would think there's a much greater reward than $10M that the market would provide. You don't think that if GM or Ford or Honda or Toyota or Joe Garage inventor could come up with a *normal* vehicle that fit cars, trucks, and SUVs, and make it get 100+ mpg, all for a competitive cost (ie, same as or less than our cars are now) that they wouldn't?

The truth is, as much as the idealists would like to think otherwise, price and value are running the show. Fuel efficiency is an added bonus, and as gas gets more expensive this will only increase. Although, I honestly don't see it REALLY making a difference until gas gets $20+/gallon, maybe more. Think about it - it sucks paying $3 a gallon, but we do it because we have to. If it jumped to $5, it would suck even more, but we'd still pay it because hey, most people gotta get to work somehow and that's the only option. Rising gas prices crimp our lifestyles that we've chosen, but at what actual price point does the price of gas and the cost of driving actually truly outweigh the need for your chosen employment? For the majority of people? The automakers, all of them, are only giving the people what they want.

Back on topic, I don't really see this as anything more than a novelty, and a stupid one at that. How much would GM make if tomorrow they released say an Impala priced at the same it is today, but with 200mpg, and where you don't have to change your driving habits or make any radical fueling style changes. You can "fill" it up the same places you can now; i.e., it's not more work for you the consumer. Wouldn't that be worth a heck of a lot more than $10M? You don't think they're already thinking about this?

The point is people want fuel economy and savings, but they don't want to drastically change their lifestyles, rightfully so. I want the insanely high Miles Per Fillup. But I want to pay a comparable price to what today's average "normal" car sells for...a $5-10k premium is too much. I want the ease of being able to refuel it anywhere - I don't want to have to come back to my home base, or only be able to go to certain filling stations. And I want this in any vehicle I choose - be it car, truck, van, SUV, motorcycle, etc. Why does fuel efficiency have to equal econobox? Why can't I have a 200mpg Hummer? This isn't rocket science, and this "prize" isn't going to push the revolution any faster.

Re:Why 100 mph minimum speed?

[norkakn]

It's really not fun to drive a car near its maximum speeds. (Acceleration goes to hell). And, at some point, someone will probably want to go 75 up a hill.

Re:

[Falstius]

I suspect your reasoning is right, but it is also forward looking to have a 100MPH top speed. As more automated controls are added to cars, highway speeds of 100MPH would be reasonable.

Is 100 mph reasonable on the Autobahn?

Re:

[khallow]

I'm not really sure what you are trying to ask. 100 MPH is a reasonable speed for the German Autobahn (at a glance it appears that the generic recommended speed is 130 km/s which is slower). Most other roads have speed limits far short of 100 MPH.

Re:

[427_ci_505]

Sometimes you need acceleration, even at relatively high speeds.
For that you need power.

More power increases the top speed.

Re:

[c_forq]

If you've ever driven a car at its top speed you would know. You don't want to make the top speed the highest speed you expect people to travel. In this case they probably want to allow the driver to go 70 mph up a hill.

Re:

[truthsearch]

Ever drive a car near its top speed? For long drives you don't want to run the car near its extremes. You'll wear out the car very quickly and you probably won't enjoy the ride.

Re:100 MPH?

[AGMW]

How many places in the world is it even legal to drive that fast--much less safe?

Well, Germany springs to mind, Ohio during the day (was it Ohio that has unrestricted speed limits during the day - or have they revoked that rule already!).

Is it safe? The Government, well ours in the UK anyway, have been doing a great job trying to make people think that speed is somehow inherently dangerous. Heads up folks ... it isn't!
On a (reasonably) clear motorway in good weather in a well maintained car and 100MPH is actually fine. On the other side of the coin, 20MPH outside a junior school at chucking out time may well be the posted speed limit but could be way to fast! This is the basic reason why most people have no respect for the law when it comes to speed limits - 99.9% of the time the posted limit isn't appropriate, and yet they try and enforce the limits 100% of the time - exactly who are you protecting by giving a ticket to someone passing a school (often now a 20 limit in the UK) at 25 or 30 MPH at midnight? It's farcical!

We've had variable speed limits on the M25 for years now ... why not have a 15MPH limit by schools when it's the times that the kids arrive and leave school (in mummy's humvee usually!), 20MPH for the rest of a normal school day, + 1hr either side of school time, and 30MPH (or whatever is the prevailing limit in the area) the rest of the time?

Ohio during the day (was it Ohio that has unrestricted speed limits during the day - or have they revoked that rule already!).

I think you are confusing Ohio with Montana. [wikipedia.org] Ohio actually has the most speed traps in the US, and Montana got rid of that law. Germans actually used to travel to Montana because it was actually easier to drive fast in Montana than Germany due to all of the congestion on the Autobahn.

Re:100 MPH?

[MobyDisk]

The Government, well ours in the UK anyway, have been doing a great job trying to make people think that speed is somehow inherently dangerous. Heads up folks ... it isn't!

I'm glad that is your opinion, but the statistics [tfhrc.gov] seem to disagree [fairtrafficlaws.com] with that statement [nap.edu] and show that severity and likelihood of accidents is directly proportional to speed [sciencedirect.com].

Mod parent up!

[smellsofbikes]

Sure wish I had mod points today.

KE = 1/2*M*V*V: kinetic energy rises as the square of the speed. Claiming that speed isn't inherently dangerous is like claiming jumping off buildings isn't inherently dangerous. While it might be possible, though skill and safety equipment, to minimize that danger, it still clearly rises with speed.
Add to that, that while well-trained drivers with excellent reflexes might be capable of driving at high speeds safely, many inexperienced drivers with below-average skills or reflexes cannot, and they may not be aware that they cannot. Most people think they're excellent drivers, even people who clearly aren't.

I'd love to see driver tests done like pilot tests: every two years (or more often for professional drivers) complete retest, and loss of driving privileges until the driver takes classes and passes the retest.

Re:

[TnkMkr]

The 100mph on a flat surface is metric for driving the available power to the wheels of the vehicle. Power required at the wheels is driven by many factors including, vehicle weight, aero drag, road incline, current vehicle acceleration demand, and rolling resistance.

The power required to maintain 100mph does not take into account power draws for road incline or vehicle acceleration. So the idea is to drive the designed power output of the drivetrain, such that reserves exist to allow for desired levels o

[Alexpkeaton1010]

From TFA:

Those that qualify will race their vehicles in cross-country races in 2009 and 2010 that will combine speed, distance, urban driving and overall performance.

You could abuse the rules, but will you still win the race?

Re:

[truthsearch]

My guess is they want something consumers will easily accept. The closer to today's common vehicle, the more likely people will buy it.

Re:

I'm no expert, but it would seem to me that three-wheeled vehicles would be more prone to flipping in an accident or tight turn.

Re:

[badboy_tw2002]

Bad summary. RTFA, they have two categories - one for normal cars, one for alternative models.

Re:

[Ngarrang]

I don't know if a 3 wheeled vehicle would be a non efficient platform or couldn't cope with all the other requirements, but if they're looking for something extraordinary, why limit themselves with something like "Must have 4 or more wheels"?

I question this limitation, as well. Three wheels means less resistance on the road than four tires. Also, 3-wheeled vehicles in many states count as "motorcycles" and are way cheaper to insure as a result. The Aptera (http://www.aptera.com/) is an example of this.

Re:

[Alioth]

Small gas turbines might be smooth, but efficient they are most definitely NOT. Reciprocating engines are miles ahead of turbines in terms of thermodynamic efficiency.

Gas turbines only start getting efficient when you're talking about a Rolls-Royce Trent 700 or a GE90.
