The World's Fastest Electric Car
Roland Piquepaille writes "In this review, Forbes.com looks at the fastest electric vehicle in the world, the tzero roadster built by AC Propulsion Inc. 'The tzero does 0 to 60 mph in 3.6 seconds, according to the company, and it does it on only 200 horsepower.' The company says it starts faster than a Ferrari F355. It also has a limited range of 280 to 300 miles at 60 mph on a single charge. The company expects a price somewhere between a Porsche and a Ferrari, but Forbes says it carries a $220,000 sticker price. This overview contains more details and links. It also includes a rendering of the Tzero. Please note that the Forbes article has a very different focus from the one mentioned in a previous Slashdot reference."
The picture on the website says 100 miles at 60mph and 0-60 in 4.1 seconds (still not slow).
100 miles at 60mph is nothing special nor is it anything good.
The difference between a traditional electric car and one of those new-fangled hybrid cars is the power source only. What is really amazing about this car is that a 110lb electric engine produces 200 hp and that easly makes the transtion between electic, hybrid, and hydrogen cars. I am still scatching my head about diesel engines being included.

Anyone who golfs knows what kind of punch an electric golf cart has from a stand still shouldn't be surprised by this. Nothing beats waiting for your playing partner to get one foot in the cart and then flooring it. He gets bended backwards over the seat like a pretzel. Pisses at your and struggling with a sore back, he shanks it the rest of the round. Fun with inertia!
if it's like a laptop, you will have to change de battery after 1-2 years!! and how costly is a car battery??
.. it's damn ugly :), though taste is no matter for discussion!
I fuse with Mercer every single day...
What about the Tengo?
It gets 0-60 in about 4 seconds, and a top speed of 130MPH. That is certainly better than 3.6 and 60.

How are electrical cars more energy efficent than gas powered ones? We get the majority of our electricity from burning fossil fuels.
If we all convert over to electrical cars, will be not just burning more oil and coal in our power plants?

How much coal, oil, gas is required on a large scale to make all of that extra electricity that would be required? Seems to be close to a zero sum proposition.

Also, is the electric car most efficient (in terms of miles per.. um, Watt I guess) at 60 mph? Or was that speed chosen because it's what gas-powered cars use?

This vehicle is strictly a concept car. Not too many will be sold at this price. The real front in the auto wars is the hybrids. Toyota is taking the lead on this. The US automakers are being left in the dust in this market segment. Check out this article. When hybrids go mainstream, it will be like the 70's when the US automakers were so far behind in quality.

..the only reason that 200hp can push the car to 60 in ~4 seconds is because the thing is the size of a matchbox (look at the Gallery pics, the car is about as big as a gas pump :D). I suffered with an MR2 MkII for a couple of years, this thing looks 2/3 the size...good thing it only has an hour range, my legs couldn't take much more.

Electric motors, unlike internal combustion engines, can generate maximum torque at zero RPM. This translates directly into excellent off-line acceleration, impressive 0-60 times, and all-round high performance. Around-town driving in an electric car should give the impression that there's a much bigger engine due to our preconceptions based on internal combusion (thus, the comment "only 200 hp"). Top speed, however, will seem stunted in comparison to that available from an internal combustion engine because they generally produce increasing torque with increasing RPM (especially below 2000 RPM).

The substantial storage capacity of electric car battery packs would also give benefits for the electrical grid (which should be high on our list of priorities after 8/14/2003). See the papers at acpropulsion.com about vehicle-to-grid ancillary services.
And no, I have no relationship with these guys, I just think they're clever and have a damned good idea.

Draining precious battery power to keep our fat American arses from melting to the seats is a major reason why Electric cars are but a fantasy in the US.
I believe your right. I might have been 14 when we got rid of that car. I am thinking that it was a 1980 model. I know that we had it before the '82 Prelude. I know that my Dad wasn't too happy with the car, I remember going up to New England and having to plug in the car overnight. However we did have another Olds and I think that was the 98 I was thinking about. That car had the biggest trunk, it was great for sneaking in extra people at the drive-in (yea there was still one of those around; it was in bad shape).

I remember reading this story in Wired some years ago about electric vehicle drag racing. The article talks about the National Electric Drag Racing Association (NEDRA), among other things.
Some of these cars are what you think of when you think of drag racing; some of them aren't, like this street legal 1972 Datsun 1200 "White Zombie" mentioned in the Wired story. Some people build electric motorcycles too; check out the KillaCycle .

Once again, full electric vehicles are shown to be just not practical. I realize this is not a normal daily driver electric vehicle, but for $220000 you'd be better off buying a normal performance car. With 20 years of gas you'd still spend much less money.
Personally, I'm waiting to see how Hybrid vehicles evolve. What I really want to see is a Diesel/Electric hybrid. Small Diesel powered cars need to make a comeback in the US.

It's a start, isn't it? Do you think when the first computers were being knocked together out of valves and punched-card readers, and filling up a room, their creators shouldn't have bothered because they were so expensive that the masses couldn't afford them? Or are you glad that they did, and that continuous innovation's put ever more powerful tools in the hands of an ever increasing proportion of the world's population?
Why are electric cars always so ugly? I understand that they design them to be functional and put asethetics on the back burner, but would it really be so hard to make it nice-looking? Do they think that someone who has $220,000 to spend is going to want a car that looks like that when there are so many more beautiful cars for that price that will offer nearly the same acceleration and a much higher top speed?
Up until recently, hybrids suffered this same fate (It's gotten better recently with cars like the Civic hybrid, though). Look at the Insight, for god's sake. Sure, I'd like to drive a hybrid or electric car, but I don't want to go into my garage and frown every time I look at it.
-- Dr. Eldarion --
When I was a nipper, they said electric cars would be the transport of the future.
.5 * m * v ** 2}. Assuming the energy stored varies linearly with mass {reasonable IMHO - amount of energy stored per mole of reagents would be a constant for a given chemical reaction}, it's not strictly a losing battle, but it's certainly a nil-nil draw. Every kilo you add to the battery is another kilo you ned to lug about. Unless you have a reaction product you can dump as you go .....
A quarter of a century on and they're still being touted as the transport of the future.
They probably always will be being touted as the transport of the future.
Nobody has ever made a battery-powered water heater, nobody ever will, and there's a very good reason for that. Energy density has pretty much maxed-out. Crucially, so has motor efficiency. You already can convert over 90% of the energy stored in a battery to kinetic energy. Regenerative braking is standard now - so the energy you expended while accelerating can be recovered when you slow down. There basically are no more efficiency gains to be made.
Electric cars are also at least as polluting as any other fuel, because the energy has to be generated somehow. The charging and discharging process is less than 100% efficient; so some more {anywhere from a little to as much again, depending on the battery tech used} energy is expended charging and discharging a battery than would be expended if whatever kind of engine had turned the generator had been used to turn the car's wheels.
The greater the mass of the battery, so the more energy is required to accelerate it to a given speed. {KE =
That's not to say that electric vehicles don't have a place: they do. And that place is anywhere where electrical power can be delivered to the vehicle without relying on a local battery to store it {at least, not a full journey's worth}.

"Put 100 megawatts of power into a transmission grid and I doubt much more than 50 or 60 megawatts come out the other end."
False. Modern transmission systems can achieve under 2% loss in large-scale power transmission. And that's talking about a scale of Terawatts Hours, not Megawatts (keeping in mind that as the amount of energy lost in transmission is proportional to the amount of energy transmitted). Granted the site is for the UK power grid, but it shows you that any modern transmission system is ridiculously unlikely to be operating at 50% loss on a megawatt scale, even when dealing with distribution levels (transmission refers generally to connected substations, etc. on the power grid, distribution refers to how it gets to your house from there).

I would think that you could drive a generator with a gas-fired turbine, keep the electric motors on the wheels and get much more efficiency than most cars while allowing you to use the current energy storage infrastructure (IE: gas stations.) I can't imagine that a turbine would be much heavier than the huge batteries these things require. Transitioning to diesel, hydrogen or propane wouldn't be all that hard, either.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
What this was probably supposed to do was start an electric car market and begin to remove the stigma around eletric cars. Electric vehicles are usually perceived as having less range and less power than their gas guzzling alternatives. This is about making it so that people arent put off by the lack of a noisy, loud, combustion engine.
Car manufaturers put a lot of effort into tuning an engine so that it sounds powerful. Engines could be quieter, but people want to "hear their horsepower". This is also done with vaccum cleaners. It is all about changing the american veiwpoint of the world.

My antique Acura gets ~28mpg, range ~300 miles -- same range as this car. Doesnt sound limiting to me!
I believe this isn't the fastest.
There was an electric car powered by 1000's of sub-C NiMH batteries called White Lightning II and it hit the mark at just a tad above 245MPH.

If you could recharge the batteries in under 15 minutes, then that would be excellent. I can fill my 32 gallon tank in about 5-10 minutes (depending on how busy the pump is), and go about 380 miles on it. Maybe less if I don't stick to the "beaten path" (read: pavement).
-- Liberalism is a mental disorder.
IMO, I think this vehicle is overpriced. Most electric motors will out-accelerate equivalent gas-powered ones. Here are some links to other fun electric vehicles that the common man can actually afford:
An electric crotch-rocket style motorcycle for $6800 at Electric Motorsport
An electric dirt-bike for $4699 at Electric moto
And economies of scale won't help much. We already make lots of laptop batteries. Maybe they could create (much) larger automotive Li-ion batteries -- fewer batteries, fewer chargers, less complex wiring.
But while it's an exciting car, I don't know if it's an important car.
Behold the riant ape! Beware, his crooked thumbs!
weight is MORE important than hp. hp can overcome weight, but that doesn't help handling.
it's surprising how many people don't consider the weight of a vehicle when comparing them. eg, the guy at work who thinks his 3100lbs 175hp altima is way faster than my ~2200lbs 127hp escort gt.

I live in Quebec, and every article I read about electric cars mentioned that using them during winter is an issue. I never heard of one that did not have its performances and independence badly reduced because of cold temperatures.
Does that one still work at -20C or -30C ?
The google news article is here and a picture of the vehicle is here.
All of the technologies that are needed for powerful electric cars are relatively new, but they are all present. IGBT transistors, digital controllers, and simple-yet-powerful induction motors are all relatively new but are deployed in production hybrid cars. The big hole (still) is the actual cost of the batteries, as you point out.
The efficiency argument you make is a canard, for reasons that others have hashed out elsewhere in the thread.
But
Like flat-panel screens, electric cars will have their day, and we won't go back.
Marc2k has a good point, and you also have to look at the cost of turning crude oil in the sand into gasoline at the pump.
.
You got wells to get it out of the earth, oil tankers to transport it to the refinery, a large staff at the refinery, and big-rigs/drivers bringing it to your local gas station. That would be the large "gas-engine" counterpart to the small loss encountered by the inefficiencies in the power grid. At the very least, this would cut down on the big-rigs on the road and the pollution/congestion they create.
The part that excites me is that it will open the door for alternative energy sources. The world will no longer have to rely on the middle east for oil to power the cars. If OPEC decides it wants to raise the price of oil again, we can just make more nuclear power plants(or some non-fossil-fuel plant)
Looking even farther into the future, consider the combination of these vehicles with fusion power, when it is perfected. Then, range would not be an issue. You could have a car that could do 0-60 in 3.5 seconds, and not have to be refueled for 200 years. And SOME company would be able to do it for well under $200k.
Can't have people returning dead batteries on their dime.
What makes that limited? My car has a range of about 250 miles in the city, 300 or so on the highway. Admittedly, it is an SUV. But I don't hear anyone complaining about the limited range of SUVs...

Just because you can mod me down, doesn't mean you're right. Shoes for industry!
It is odd to me that Forbes seemed to complain that the TZero ONLY has 280-300 miles in range on a single charge.
My first car, which had a 16 gallon tank only did about 300 miles before it needed a refill. I think many of today's SUV's have a similar range. Yeah for a serious road-trip it becomes a problem because you can't just stop at a gas station, but I don't think this little roadster is a long-haul kind of vehicle anyways.
Don't moderate flamebait as Troll. Know the difference or you will be Meta-moderated.
What consumer would buy this thing? Think about the target market for a second.
Hmmm, let me think for a second...
But uggly electric car or gorgeous looking Ferrari. No thanks, I'll keep my Ferrari. I'll make up for the lost karma in my next life!
Black holes occur when God divides by zero.
The Toyota Prius is NOT designed to get the maximum efficiency. It's designed to get TDI-like efficiency with "all the trimmings" -- it's a quiet, moderately zippy family car with a lot of goodies that would have been factory options a decade ago. The Toyota engineers chose not to go for maximum efficiency (like the Honda Insight), but rather for the efficiency of a jellybean car (like the Geo Metro) in a quiet, comfortable, safe four-door.
so in essence, I was still correct in stating that this tzero-whatever wasn't the fastest electric car in the world. (maybe for the "consumer" market though the price tag makes it so only a select few can afford it)
Today's Washington Post reports that the major automakers are abandoning their electric car research programs, putting all their eggs into development of hybrids and hydrogen fuel cells.
Well lets start with the zero emissions. It is a lie - there are emissions at the plant where the electricity is generated and where the batteries are manufactured (AND disposed). Every car crash of one of these new Li battery chemistries could become a mini super fund site.
And now efficiency - in the real world we generate electricity at a certain thermal efficiency loss then we transport it to ones house at a loss then the battery is charged with a certain loss and then stored with a loss and discharged with a loss. The real efficiency is
P*k1*k2*k3*k4*k5 = D
or
Pk=D
Where O is the original power and the kx s are the efficiencies of each transformation or storage (all less than zero) and D is the delivered power. The second equation shows that the kx s all combined into one coefficient. In all the electric/hybrid car stories no one ever states these numbers because they suck.
And lastly remember energy density:
I appreciate the wishful thinking of the hydrogen folks, but ask any hazardous material team about how dangerous hydrogen is - it has an invisible flame front - is explosive over a huge range of air/H2 concentrations, rots it's metal containment system. Besides, having a volume energy density that is about 1/4th that of gasoline.
Gasoline 9000 Wh/l
LNG 7216 Wh/l
Propane 6600 Wh/l
Ethanol 6100 WH/l
Liquid H2 2600 Wh/l
Lithium 250 Wh/l
Flywheel 210 Wh/l
Liquid N2 65 Wh/l
Lead Acid 40 Wh/l
Compr Air 17 Wh/l
Hydrogen 2.7 Wh/l
Come on folks you are smarter than this!
"There was an accident this morning on 101, and as a precaution the surrounding 2 counties were evacuated due to possible radioactive contamination"
The problem is that your basic assumptions about gas engines are completely incorrect. From a consistent work/power aspect they are quite shit. Take a look at this dyno graph:
Ferrari 360
The line with the hump in the middle is the torque, the line that goes mostly from bottom left to top right is the horsepower. You'll notice that at idle, the Ferrari makes about 60 horsepower. Not much, huh?
The beauty of electric motors is that they have a constant power output at any speed. If this electric car were tested on the dyno, the graph would be a FLAT LINE at 200HP. The electric car's secret is that it's able to gain speed very early (before the gas engine has time to realise it needs to start working).
Your MR2's peak power output would be the electric car's *constant* power output, even at zero rpms when launching.
If people can settle down on a method of disposing of the waste, special nuclear reactors would be very effective at producing hydrogen.
They'd do it by boiling the water into a near-plasma, where the hydrogen and oxygen ions become separated. The hydrogen ions would then be separated from the oxygen ions.
I would imagine that such reactors would produce less nuclear waste over a given amount of time than electricity generating reactors, because the useful life of a given amount of fissile material would be greatly extended.

This is not the fastest electric car (and I am not talking about dropping it from an airplane). There's a British group whose car did 149 MPH on its first test.
Horsepower is important, but not the only thing to consider. A "200hp engine" means that the maximum horsepower is 200. The power of an internal combustion engine varies greatly with rpm. So, at some specific rpm, the engine outputs 200hp.
The power of an electric motor (not sure what kind is in the car), does not vary as much with rpm. It's maximum is still 200hp, but it is also able to produce more power than the internal combustion engine throughout most of the operating range.
So the electric motor produces more power than the internal combustion engine throughout most of the operating range, allowing it to do more work in the same amount of time.
He said fusion, not fission. "No rads for you! Come back, one year!"
" If OPEC decides it wants to raise the price of oil again, we can just make more nuclear power plants"
No - the current political regime does not see things this way.
OPEC does not raise the price of oil. OPEC cuts supply. This has the effect of raising the price of oil. Which is enormously profitable for domestic oil producers. Who donate huge sums of money to politicians to ensure that this continues to happen.
So you see, there's NO incentive for domestic energy companies to abandon the profitable oil business and compete with other energy sources like nuclear, solar, wind, or faeries, and it doesn't have anything to do with whether a given technology is green or not. Has everything to do with how profitable it is to keep the market dependent on the artificially scarce resource.
These are my friends, See how they glisten. See this one shine, how he smiles in the light.
I took plenty of physics. Torque is a measure of the ultimate work your engine can do, how much of a load it can move. HP is the measure of power, how fast the engine can apply the torque. High-HP high-rev engines are usually relatively low torque, so they won't accelerate a lot of mass (that's why sports cars bog down so much when you have a full load), but they'll get it moving very quickly; Formula 1 cars are running 7-800 bhp, but less than 250 ft-lbs of torque. They accelerate at ungodly rates, but are hyper-sensitive to changes in the car's mass. Yeah, the shape of the torque curve is a huge factor as well, and the monster low-end from electric motors is great for pushing big cars up to speed...but for small-car peformance, where you keep the revs high enough to not worry about low-end figures, and the torque numbers are comparable, 200hp is 200hp.
Facts do not cease to exist because they are ignored. - Aldous Huxley
"Please note that the Forbes article has a very different focus from the one mentioned in a previous Slashdot reference."
What about this article, or perhaps this one?
The tzero does 0 to 60 mph in 3.6 seconds. The VFR will do it in 3.0 seconds
It also has a limited range of 280 to 300 miles at 60 mph on a single charge. I get about 200 miles at 75+.
The company expects a price somewhere between a Porsche and a Ferrari, but Forbes says it carries a $220,000 sticker price. The VFR was $11,000 new, out the door, all taxes, fees, and other California bullshit included.
Now if this were a useful car, something with 4 doors and a trunk and a roof, I'd be impressed.
Too big to fail? Does that make me to small to succeed?
Maybe they "can" (as you put it) achieve under 2% loss in certain situations, but the US national average is about 14%.
This is one of the main arguments for distributed power.
Well I know of several electric cars that go faster, provided they are dropped from an airplane.
If we were to tell Opec to go to hell, we'd also be telling KBR(a subsidiary of the Haliburton Corp, old CEO of Haliburton, you guessed it Dick Cheney) and Bush to go to hell. Odds that Bush and Cheney will tell themselves to go to hell, less than a snowballs chance.
The electric drive motors of a car like this, but instead of a big battery, have a highly efficient gas turbine engine that runs a generator, and have it run the electric motors.
.
You have the GT run at a constant RPM, and a smaller battery that is used for saving the regenerated electricty from stopping ( dynamic braking ). It also provides the startup power to get the turbine up to speed before it lights off
Volia! Much longer range than the regular electric car, and much more efficient than a standard IC engine.

The fastest electric car on the list can do the quarter mile from a dead stop in less than 9 seconds. To give you perspective, the Ferrari Enzo is the fastest production automobile Road and Track ever tested, and it does the quarter mile from a dead stop in 11.8 seconds.
The tzero may be quick, but it's not the fastest electric car.
No, this isn't a dupe. Yes, it IS related to the earlier article, but there is still the defferences between then and now
The Ferrari has met US crash requirements. The T-Zero has not, and would weigh a lot more than it's sub-2000 pound weight if it had the required door intrusion bars, crush areas, etc. By the time it gets certified, it'll be a lot heavier and slower than the demo version being touted in the article. I predict it will end up slower than the Ferrari.
Ferrari, Porsche, etc. could easily build a car that outperfomed the TZero, if they weren't required to follow any guidelines about occupant safety. Porsche had a race car whose frame, suspension, driver's compartment and body weighed less than 100 lbs (the 904? I think). Of course it was the late 60's-early when race sanctioning bodies weren't too concerned about safety. Add the drivetrain of a 2003 GT3, and you'd have a 450+ HP, sub 1000 pound car. Of course, you'd also have major damage and possibly injury in the event of even a small fender bender, but it'd be as street legal as the T-Zero, and out-perform it in nearly every category. It's just a show car, the production version is a long way away.
In a race from say LA to New York (3200ish miles): Ferrari - 53ish hours at 60MPH (well under legal limit), plus over 6 hours to fill up 12 times, 60 hours total worst case.
T-Zero - 32 hours at 100 MPH (top speed), plus 42 hours of charging (at 4 hours/charge), 74 total hours best case.
The T-Zero loses every race over 300 miles over about any car.
This sentence no verb.
I am not an expert on this, and sfbanutt touched on this down below, but as I scanned the posts I don't think anyone has explicitly cited this as an energy-saving step:
Traditional cars are like blast furnaces on wheels. You hit the gas and accelerate, then when you stop all that speed is converted into waste heat by your brake pads. Incredible losses.
Regenerative electrical cars use the motor as a generator on deceleration. This exerts a braking force and allows the car to recapture some of the energy. Ideally you dump it right back into the batteries. Other methods involve spinning up a flywheel as you decel, keeping the energy in a mechanical (rotational kinetic) form.
I can think of quite a few faster vehicles. Most record holders of the national electric drag racing association would blow this car's doors off. If you want to get technical, there are electric airplanes that are faster, and the new ion propelled european satellite is quite a bit faster.
People who think they know everything really piss off those of us that actually do.
As long as electric cars look like electric cars, they will never ever catch on. I don't care if the damn thing can go back in time, if it looks like some kind of science fair project it's not going to win the hearts of consumers.

As I recall, c. 1973 Suez was a problem. Since then a number of oil fields have been torched and many countries are at the mercey of OPEC, Venezuala, middle east unrest and sabotage of pipelines etc., For freedom in troubled times, we could do with freedom from imported fossil fuels. Hydro, geothermal, wind, nuclear and other sources tend not to be portable but batteries and fuel cells certainly are. Faced with the possibility of petroleum based fuel shortages - some of us have lived through similar already and seen corporations loose millions /$
I tend to think we should be open to new possibilities. Otherwise we may as well go back to the plough?
Cheers.
My hyperlinks aren't worth the paper they're printed on.
this is pretty obvious if you think about it - if half of the electricity produced in the country was lost, you'd see a dramatic heating effect over transmission lines :)

Quick summary: Gasoline emissions contain smaller particulate matter than diesel emissions, which carries a greater risk of causing cancer (easier to absorb into the lungs).
Gasoline engines produce more toxic emissions than diesel engines.
Diesel engines pollute MUCH less than gasoline engines (some study results in the links above).
Diesel engines not only have much better efficiency than current gasoline engines, but also hold the capacity for even greater efficiency as technology improves (even more than direct injection gasoline engine technology).
---
I grew up with diesel engines (farming, heavy machinery), and can't stand the blatantly incorrect assumption people currently hold against diesel engines: That diesel engines pollute more than gasoline engines. It is absolutely wrong, and people need to inform themselves so the spread of disinformation STOPS.
The world runs on diesel. Busses, trains, tractor-trailers, heavy machinery used to grow and harvest the food you eat, the equipment that people use to build cities... The USA does it's heavy lifting with diesel, as does the rest of the industrialized world.
Sure, fastest off the line, but how about pit stops? "The tzero can only go 280 to 300 miles at 60 mph without recharging--even if it can recharge on any 120- or 240-V power socket. And if you accelerate it like an Italian exotic, or even take it on a hilly route, that range can decrease by up to about 20%." Fine. My car goes 200 to 300 miles on a charge (a tank of gas). If I'm going that far or farther, I'm glad to stop and get out, if only to stretch my legs while filling up. Doing so takes me 5 minutes or less. That's enough for me, and I'm on my way: places to go, etc. So how long will it take this thing to recharge to a "full tank"? If it's going to take an hour to get back on the road, it doesn't matter how fast it accelerates.
"I may be synthetic, but I'm not stupid." -- Bishop 341-B
Actually, we couldn't do that unless existing cars could run on hydrogen without modification, which is clearly absurd.
We might be able to go towards that goal in a couple of decades, but we're not going to get rid of OPEC tomorrow or even ten years from now, because most cars are still going to run on oil.
That can change only gradually.

The Horsepower and Torque numbers tell the real story - plus the last report where they were bragging about beating gas engined sports cars, but only in a 1/8th mile drag. If you gear it to take advantage of the torque for acceleration, you will out accelerate machines with less raw power, but taller gearing. You're using the gearbox for torque amplification, and that peters out once you run out of revs.
About a dozen years ago I raced motorcycles. An obsolete one at that. If I geared down for acceleration I could keep pace with a (then) modern Suzuki GSX/R on my aged KZ650. At least until I ran out of revs and they pulled away, where I was hitting red-line at 118. If I regeared for higher speed, they'd pull away under acceleration. Racing was finding the balance and relying on the rider not the power. (Mid pack finishes in 750SS and Formula 1 - not bad for a 12 year old bike at the time)
The T-Zero is playing the Acceleration game for publicity. The numbers look nice, but I can get better range, speed, etc., from a well tuned gas burner for 1/10th the price. Hell, but 1/10th the price I can get a new Prius and be Eco_friendly and out run the T-Zero on a long straight!
Never attribute to malice what can as easily be the result of incompetence...
Frankly, I'd have no problem driving a car to work that only had a 100 mile range if I could negate the fact that once a month, and emergency comes up at a remote location and I have to drive 120 miles with virtually no forwarning.
:-)
In addition, I don't want to have to own a SECOND car, if I decide to go skiing on Saturday and have to drive 90 miles uphill on the Interstate to get into the mountains... and then expect to be able to get back... or not be stranded if an avalanche on the road blocks traffic 5 miles short of my destination.
*shrugs*
If the electric car can be recharged in 20 minutes, it might do, since a "filling station" infrastructure could be built, but to be perfectly honest, if it takes hours to charge, I'd be stuck spending the afternoon on the mountain at the base of an avalanche field if the car takes 8 hours to recharge.

There are 10 kinds of people in the world. Those who understand binary and those who don't.
As far as clean and effecient fuels for transportation go, can anyone comment on natural gas in comparison to electricity?
"he drew his sword Ringil that glittered like ice... and he wounded Morgoth with seven wounds..."
So why would the range be a problem? A car like that is not meant for long distance travel anyway - a couple of hours on bendy roads can be fun, but extended driving in something without power-steering is exhausting.
Kill'em! Kill'em all!
How else can your average person afford a 250+HP mid-engined sports car, sure second-hand Elise is getting cheaper now but they are overkill for the average driver.
Kill'em! Kill'em all!
You want to centralize the dirty stuff in one object
:-)
Kinda like Windows, huh? Concentrate all the flaws in one company, then when the revolution comes we only have to blow up one place.
Seriously, your analogy with OOP is grossly inadequate. Consider:
1) The most clean and efficient fossil fuel to electricity conversion plants available today are "neighborhood" size fuel cell plants. Combined cycle efficiency up to 80%, near zero emissions. Still too expensive for you & me, but prices are bound to come down with mass production.
2) Likewise, wind, solar, wave, geothermal, and other renewable generation technologies are efficient, and much less intrusive on the landscape, at "neighborhood" sizes. Hydroelectric and nuclear are the only ones left where large power plants make sense on efficiency grounds, at the cost of their associated environmental problems.
3) As you may have noticed lately, the electric distribution grid is severely overstretched, and due to NIMBY new high voltage lines are getting almost as hard to get approved as nuclear power stations. The obvious answer is to generate the power closer to where it's needed.
4) Do you know just how long the planning, approval, and construction cycles are for large power plants? Market forces (assisted by judicious selective taxation and subsidies) can create a million small new-technology power plants MUCH faster than you can build a single centralized Gigawatt monster.
And yes, the analogies to the open source movement are striking. Free Power Foundation, anyone?

Be faithful to your obsessions. Identify them and be faithful to them, let them guide you like a sleepwalker. JG Ballard
The real point is that gas-turbine cars have been built, and they were very smooth and quiet. Regardless of what a particular system may create in decibels, it can be and has been done better than the screamers with which you are familiar.
Scientists restrict study to entire physical universe; creationist
Building more power plants is one thing, but upgrading the tranmission grid for all of the US, right down to the local stepdown transformers in every nieghborhood is a hidden cost of going electric.
And what happens if and when there is another power outage like the east coast blackout a few months ago? Not only are we all sitting in the dark, but can't find a place to plug in our cars?
I'm not saying these are reasons the electric car can never become mainstream, just things most people don't think about.
