extreme performance electric supercars

How about adding this to it.



Another key part of the battery work is the development of a new electrolyte. A fourth faculty member on the MIT team recently succeeded in doing just that (the work was not reported in the Nature article).

Introducing Anne M. Mayes, Class of '48 Associate Professor of Polymer Physics in the Department of Materials Science and Engineering. Professor Mayes's new electrolyte, a polymer, has a variety of novel properties. For one, it's a solid. Conventional electrolytes are liquid, which limits the shape of the battery (you need some kind of vessel to hold the liquid).

But the new electrolyte conceived by Professor Mayes is flexible. A battery made of it "would be something with the consistency of a potato-chip bag," Professor Sadoway said. "You could fold it up to make any number of different configurations." Imagine a car powered by a battery that's incorporated into the body panels.

Real nice find Van.I am really curious of the spec's on that bad boy. HP and such.

I wonder if he rechargers between races?

Unless hes running deep cycle marine batteries in there it'd take a hella long time to charge that thing up.. I mean for a car to have enough torque to chirp and roast them at over tripple digit speeds... thats like.. gotta be .. gotta be well over 1000 HP.  No ?

He could have spare charged batteries.  ;)

In reference to electric Hp, on air compressors an electric 2 hp will keep up with a gasoline 6 hp.

So 300 would be pretty awesome.

oh shit your right lol. Forgot about the difference in hp with gas / electric..

"Quaife limited slip differential" 

ah well that explains the constant chirp and roastin lol. all that power going to it.  Thats one hell of a ride man.. wow. So in reality its about what... 690 .. 700 HP  ?

Thats so sweet.

Alittle more info.

"Electric cars are driven by large electric motors usually rated between 3.5 and 28 horsepower. For those accustomed to gas engines, this may not seem like much power, but the rating systems used for gas engines and electric motors are so different that the numbering system is almost meaningless. Gas engines are rated at their peak hp, electric motors are rated at their continuous hp. The peak hp of an electric motor is usually 8 to 10 times its continuous rating."

Motor Information 

"It should be noted, that comparing electric motors with gasoline engines is like comparing apples and oranges. Gasoline engines are rated at their peak power, and electric motors are rated at their continuous power. It is for this reason that a 30 hp electric motor will generally perform like a 50 hp gasoline engine in a same weight vehicle. Of course the addition of a large number of batteries will diminish the vehicle's ability to accelerate or climb hills."



"The brushed series DC motor is the best overall motor for affordable road-going conversions available today. AC motors operate at high rpm that have to be stepped down, and have expensive and complex speed control systems. Brushless DC motors (actually another kind of AC motor) also require expensive controllers. Permanent magnet motors are very efficient, but only in a very narrow rpm band, and quickly lose their efficiency in the varying speeds of normal driving. Shunt and compound motors are more expensive to build and have poorer acceleration than series motors. For these reasons, the brushed series DC motor is the motor of choice." 



"Electric motors convert electrical energy into mechanical energy. Two types of electric motors are used in electric vehicles to provide power to the wheels: the direct current (DC) motor and the alternating current (AC) motor."



The Horsepower ratings for Electric Motors are a little deceiving, Electric Motors have about 3 times the torque than gas motors and the peak horsepower is basically limited only to the controller used. An Advanced DC motor rated at 17.5 hp will power a Geo-metro to over 70 mph.



According to this it could (8-10) 1888-2360 HP, or (30-50) 393 HP. And the torque would be aproximately 546 lbs. Torque.But evidently a lot of zoom.

Actually a rotary engine like Mazda's would probably come closest by comparison.  ;)

comparison testing with a rolling start has one real world aspect though: passing.

although this is more a factor in europe where trucks have lower speed limits than cars on both overland roads and interstates it is usual to test a cars acceleration from 60 to 100 km/h and 80 to 120 km/h (about 35 to 60 and 50 to 70 mph). usually these tests are run in the higher gears (the gear used is usually specified) to give a feel for how much grunt the car has when just cruising along and then passing a vehicle.
