Tesla Motors' highly anticipated Roadster comes closer to fruition

Tesla Motors' Roadster has been in development for quite some time now, but it appears that there is finally light at the end of the tunnel for the project team.

Malcolm Powell, Tesla Motors' Vice President of Vehicle Integration, announced yesterday that The Tesla Roadster has passed all Federal Motor Vehicle Safety Standards (FMVSS) and is legal for sale in all 50 states.

"Thanks to great design, structural analysis, build quality and well run test management, we have successfully completed the entire suite of dynamic impact testing to meet both FMVSS and, as importantly, our own very strenuous internal performance targets," said Powell. "This is a great achievement for Tesla; it takes us another (major) step closer to our final goal and is another demonstration that EVs are as real as any other vehicle on the road."

The Tesla Roadster performed admirably in front, rear and side crash tests. "I always find it interesting when people say, 'Isn't it dangerous carrying all those batteries around?' Well I don’t know about you, but I’d rather carry a load of relatively inert battery cells than 10 gallons of highly volatile, flammable liquid," added Powell. "I will not comment on how other companies design their vehicles but at Tesla, we have paid great attention to the integrity of the design for crash management."

In addition, the vehicle passed basic rear view mirror, lighting and windshield defogging/defrosting tests.

Production of the $100,000 roadster will begin on March 17 although the first models to roll off the assembly line will come equipped with "temporary" transmissions.

Tesla claims that the temporary transmissions are of a design that has been road tested more than 100,000 miles, so owners shouldn't be too concerned about reliability or safety. Performance, however, does take a nose dive -- the first production models will only accelerate 0-60 in 5.7 seconds instead of 4 seconds as previously promised.

The temporary transmissions will be replaced with production-level hardware at Tesla Motors’ expense when it is available.

The Tesla Roadster is loosely based on the aluminum-intensive Lotus Elise and features an electric motor powered by 6,381 lithium-ion cells. The projected range for the two-seater is just over 200 miles.

I'm wondering, where exactly will the major improvements be had? Electric motors are electric motors. We've had them around for ages and ages, just like the ICE. The only way I currently see for anything like this to be decent, is if there is new battery tech.

As for that electric motorcycle, big deal. A shitty Honda CCR600RR can destroy a ferrari. Most stock bikes have a 0-60 of about 3 seconds, did you not know this? Plus I really doubt that bike makes 500hp, unless it weighs about 800lbs or so. My friends got a Hayabusa running @ 36psi, it puts out about 500hp, and its trap speed is 186mph in the quarter mile, with a 6 sec time.

As for "generator engines", duh. Have you ever seen how big big dump trucks work? They have huge engines for the powerplant, not for the drivetrain.

I don't doubt we will have electric cars in our future, but the current offerings are greatly inhibited until we get battery tech that dosen't suck.

If you don't want to watch electric motorcycles, watch this electric car .

http://www.youtube.com/watch?v=SsGeQby7Jnw&feature...

0-60 in 3.07 seconds . Is that fast enough for you? This car is a cheaper than some of the Lamborghinis and Ferraris too ... and they'll get cheaper still once they become mass produced .

Like I said, electric cars are just getting started. This is a "model T" electric car. Imagine how good they'll be in 5-10 years. The internal combustion engine car really is going the way of the dinosaur . Electric cars are just better in lots of ways. It's a Darwin kind of thing ... cars are evolving. You can't stop progress. Not in America anyway.

Welcome to the 21st century. This is the way it's going to be. No more loud, inefficient, gas guzzling cars burning fuel and making the oil sheiks in the Middle East as rich as God. We're going to have super efficient, quiet, ultra smooth, high torque/high horsepower electric cars. If you want to hear the sounds of internal combustion engines for nostalgia sake, you can get an .mp3 soundtrack of the old Ferraris and Porsches from "the old days of gasoline cars" and play it in your electric car. :)

I think you have some pretty serious problems reading, like eye smite. I never said that speed of that car was terribly bad or anything, or that it was a huge inhibiting factor. I said our battery technology sucks . Looking at how much energy loss occurs and how difficult it is to maintain and keep a charge, let alone at any meaningful voltage and amperage will go to show you that our battery tech is still pretty primitive.

If electric cars really want to make a move into the market, battery tech is the first and foremost, because everyone knows that electric is quite a bit more efficient then a regular ICE. But I don't think too many people will want to wait several hours for their cars to "charge" or only be limited to a minimum of 200 miles. 200 miles is under half of the range that most family or "normal" cars get. Check out the Civic, Accord, Camry, Malibu, etc, all range within 500mi or more.

In addition, that link you provided is about as much of a car as the Ariel Atom or any other of the small kitcars. Big deal, show me that in something that looks like a normal, regular car that an everyday family would get in.

Again though, just because you have trouble reading I'll say it again: I do agree that electric cars are the way of the future.

From what I've been reading there's probably going to be plenty of new battery breakthroughs on the way. Read these articles about silicon based lithium ion nanowire batteries:

http://www.itwire.com/content/view/16129/885/

http://cosmiclog.msnbc.msn.com/archive/2008/01/17/...

http://www.gm-volt.com/2007/12/21/gm-voltcom-inter...

The serial (plug-in) hybrids will have plenty of range. They are basically pure electric cars with a "range extender" which could be a super efficient ICE engine running cellulosic ethanol, regular gasoline, or E85 ... or a hydrogen fuel cell later on.

Read these while you are at it:

And none of those are being used in ACTUAL cars you can buy TODAY. Not even in the $100,000 "saving the planet, 200 miles at a time" Tesla "pose-ster".

Wake me up when this stuff is being mass produced in cars we can ALL buy. Not just some rich guys garage queen.

If only there was a way to convert the stupidity of people such as yourself into a fuel...we'd have an infinite supply. Do you realize that the technology for creating electric vehicles has existed as long as, if not longer than, internal combustion? Yes, it has been around THAT long. This car does not innovate or revolutionize anything...and if electric cars were feasible they would be more prevalent now than they are.

Internal combustion > electric for the simple facts of power-to-weight and the ability to store more energy per unit in the form of a combustible liquid vs a battery. Emissions? Here's a quick fact: the smog you see lingering over L.A or NYC is not CO2 or even CO...it is OZONE GAS. Where does that gas come from? Incidentally, it is released by electric motors among other things. Unlike the pseudo-scientific doomsday claims about hydrocarbon emissions from cars causing a climactic meltdown in 400 years...ozone poses and immediate and definite health risk to anyone who happens to breath. Also, green plants which filter CO2 do not filter ozone, so it just lingers there.

So far none of the alternative electrical "solutions" for our "fuel and environmental crisis" are viable, practical or desirable. In fact, MORE LIKELY THAN NOT, diesel powered vehicles will be the "new thing" for American consumers, since they are in fact everything that electric and hybrids are not - i.e. BETTER. In Europe, diesel powered cars are very common, very efficient and more simplistic. A staple of quality engineering is finding the simplest solution possible to a given problem.

EXACTLY. This idiot has been going on saying that we have fancy new battery tech.

What a crock of shit, he has no realization how much that tech costs, and how little it really boosts inefficiency. As far as I know, electric cars have been around a little less then ICEs, primarily because back then there was an even larger disposition in the power to weight ratio that exists to say, as well as the pathetic and paltry range of the old Lead batteries.

With diesels, you hit the nail on the head. There is no way in the world everyone will just uproot and make the decision to switch to these electric cars. Sure some of them loosely defined as cars can do 0-60 in 3 or so seconds, however so can a few select cars, big deal. Its not like there is insane money to be saved anyway.
