Electric Car Does The Quarter Mile In 5 FIVE SECONDS....

[Hairy Eater]

seen it on tv the other night... this yank is coming here to ozz soon to tell us about it... just get any rear drive 4 cylinder car, put it electric motor... do the quarter drag in 5 secs... also his electric cars go 400 to 500 klms before recharging...

i got to see this...

[maxy0987]

me too.

Fair enough they make the most torque at 0 rpm but youd still need to get the power to the ground somehow, ripping a 5sec pass would require some hell of a way to stop you from laying strips of rubber down for 400m

EDIT: found this (http://www.xent.com/may98/0331.html)
Basically saying a funny car did a sub 5sec pass. The interesting thing was the part below how a guy said a study has shown that in theory the fastest time you can rip is a 3.5sec due to friction/tyres etc etc.

I'm a sceptic.

There's currently no way an electric car could do 5 seconds - especially in a normal car.

I wanna see proof !!

To repeat the same post I made in this thread...

Hairy Eater: no offense, but whoever claimed that is full of more BS than every livestock farm in Australia combined.

It takes an 8000 horsepower nitro methane powered, 45 PSI boosted 8 litre V8 dragster with tyres as wide as a small car to do the quarter in 5 seconds. (can you tell I went to the Nationals at Willowbank over the weekend)

Hate to break it to you but short of some massive shift in the method used to convert electrical energy to kinetic, no electric car will ever perform as well as your average petrol engine. Some have come close to decent performance, but after a range of 400-500 kilometers need 12 hours to charge, rendering them useless for any long distance driving.

I think you will find this car does 0-100 in under 5 seconds, there's videos of it on the net, we were watcing them a couple months ago. There's a video where it owns a Ferrari down the 1/4

I'm sure thats what they said when they converted from coal trains to electric as well.

Admittedly electric cars are a very long way off being ready for general market use, but it doesn't mean they'll never get there.

[greenfoam]

Most of the good home made electric conversions in the states are running 13 or 12 seconds 1/4's in normal size cars allready so it's well on the way

It was designed in France by Venturi 0-100km in 4.5 top speed 170kmh,180kw electric motor,1100kg.Full recharge 3.5hrs at 80 amps or 16.5 at 16amps.

Take a look here. These motors put over 1700 Nm to the ground (INTETS) or 500Nm flat from 0 to 1600rpm (powerphase 100). Put one in each wheel and you will have a lot of fun. The reason that IC engines need to be so big for take off is that they have such poor torque at the low end.

maybe so but "just drop an electric motor into any rwd 4 cyl car" I think not... not without about a metre width of rubber on the ground.

You're forgetting the extra traction you get from the downforce of over a ton of well distributed lead acid batteries gives you, in spite of which the car had it's front wheels up in the air for about a third of the track... and the car was street legal and driven there and back as well as daily. I'd love to get one of those 2000 Amp controllers!

elecric rains dont run off batteries though, do they? they run off power lines or off diesel powered generators

[shaggerz]

as semi said!! the problem is not that we don't have powerful electric motors, because we do.... As michaelw has made clear there is plenty of power and torque there for the taking, but the hard part is the batteries.

Not sure what the rest of you think but they seem to be a horribly cumbersome way to store electricity to me since they have to be so large and heavy.

oh and starkeyholden in order for it to gain that much traction by sheer weight, consider how much extra power would be required to accelerate that great big lump of lead to 400km/h in 5 seconds...

maybe 12-13 second quarters for something initially very light (before the batteries lol... it wouldnt be light with them in)

Theres no arguing with peak torque available across the entire rev range, but in practice, very cumbersome no doubt. Weight would be less of an issue than charge time I think.

[starkeyholden]

Charge time is getting to be less of an issue, although it really isn't that big a deal to start with, To put a different perspective on things, would you rather travel to a service station once a week to put petrol in you're mobile phone to run it, queing for the pump, queing to pay, or would you rather just plug it in to charge each night?

Also running cost is becoming a rather large consideration, current EV drivers in the States calculate that the total running costs of their vehicle INCLUDING the neccessary periodic replacement of the batteries equates to about 20cents US per litre for petrol at prices current a year or so ago.
As for cumbersome due to the weight, The purpose built EV's (as opposed to a converted car) are amazingly agile and very quick around corners due to the weight of the batteries and their position (resulting in a much lower centre of gravity than standard vehicles) Footage of these EV's going through handling testing shows much less body roll at high cornering speeds than standard vehicles
