[ET] Tesla X will have two electric motors and beat a Porsche 911 to 60 mph - Page 18

post #171 of 198
I think electric cars should just have a removable battery (standard for all cars) that gets charged at a station in 8 hours, or however long it takes, and if you go there they should change your empty battery with a full one, and start charging the one you left there. Such a station would have to be able to store and charge a number of batteries equal to the number of cars that pass through in 8 hours. Of course batteries can be coupled, so it isn't necessary for all cars to have the same power/range/weight, bigger cars could use a multiple of this standard battery.

they actually have an idea similar to this (and by they i mean i saw it on discovery channel XD)
Have you guys ever seen the "Skate"?
it's a battery operated chassis with everything built into it...the frame of any vehicle can be easily attached/detached with heavy machinery.
they were also talking about making a hydrogen version.

the hydrogen version is going to be an all-in-one electrolysis mechanism and hydrogen engine. so what will happen is you fill the tank up with water, the electrolysis machine creates the hydrogen. the hydrogen goes to the engine and gets burned as fuel for the vehicle. the outcome of burning hydrogen is...get this....water. so the water goes back into the water tank to start the process all over.

the only problem with this so far is...to have an electrolysis machine produce enough hydrogen to be sustainable as fuel for the car....it'd 3 times bigger than the car. so yea...its a work in progress.

i know this is pseudo-OT but i figured this would be the best discussion to post in smile.gif

Good luck lifting the battery. The one in the Roadster weighs around 1,000 pounds.

lol yea, but just wait for nano tubes to become cheap....you may have to charge your car once or twice in it's lifetime with a battery composed of this stuff....not to mention you could make a nano-tube battery that holds the same amount of energy as a car battery...and is the size of the tip of a pencil....yea it's for real

Seriously, if some American made a comment like this about some European country they would jumped all over by people for being a, "culturally ignorant, stupid American." The United States is 9,826,675 km2 with 313 million people. Your assumptions just look plain ridiculous alongside those statistics.

When the first gas cars were out they were also overpriced piece of crap, only the riches had them.

What's crazy is that you expect people to willing hand over their money for a car that could potentially turn into a giant paperweight unless you fork over about 50% of the car's value to fix.

Read the owners manual of any car and you will find similar (but not as costly) disclaimers. Like the one about maintaining oil levels or it voids the warranty... Granted it only costs about $10k (depending on the car) to swap out an engine if levels are allowed to go too low and the engine self destructs.

It is pretty damn hard to "accidentally" cease an IC engine. It takes years of consistent neglect or some very directed, intentional abuse.

The Tesla on the other hand can go from car to brick in less than a week without an appropriate trickle charge. It is also worth pointing out that the manual states nowhere that your car will become completely unusable if the battery is allowed to deplete completely. A passing mention is made deep within the manual that "some" damage "could" occur.
Quote:
The Tesla Roadster Owners Manual begins with several "Important Notes About Your Vehicle" [Page 1-2: PDF], none of which make any mention of battery discharge. In Chapter 5 of the manual, where vehicle charging is addressed, Tesla states that the vehicle is "designed to be plugged in" and that allowing the charge level to fall to 0% "can permanently damage the Battery." [Page 5-2: PDF] It does not specify that a completely discharged battery may need to be replaced, entirely at the owner's expense, at a cost that could be the majority of the value of the vehicle.

Not always true. Take the 2002 model year GT mustang for example (this also applies to other years). By the time you realize that you are a quart low on oil, you have already spun a rod bearing and if you don't shut the engine off immediately the engine is toast. $6k to fix it.

The next electric Tesla will be an SUV that will outrun a Porsche 911 to 60 mph, carry seven passengers, handle well in both rain and snow. The Tesla X gets its power from what it calls Dual Electric Motor AWD (all wheel drive), basically one motor each for the front and rear wheels, and a 60 or 85 kWh battery.
Also from the article...

The SUV is also expected to prepare fresh coffee for the owner in the morning, take the kids to daycare, fold laundry, and cook a nice dinner daily. It ships with a private nanny for all of those moments when a vehicle is just not feasible. It also handles well in rain and snow.
Handles well in rain AND SNOW? Wow! Groundbreaking!
