Electric Engines off-road. Doesn't seem like it would be the same.
 
So, as gas prices go up and more talk about going to all electric vehicles in the near future, what are your thoughts about a fully electric 4x4 off-road vehicle?

I think I'd miss the rev of the engine, though my wallet would be happier.

Mr. Sinister 01-27-2011 05:54 PM

electric engines are ALL torque.
they need better battery technology, i would hate to run out of juice in the middle of nowhere.

As stated... 100% electric vehicles will not be viable until battery technology catches up. Electric motors that are large enough to propel a 4000lb vehicle is also going to weigh a bit, and then the battery is going to weigh 3-4x as much. The newer litium-ion and lithium-polymer batteries are amazing as far as power(voltage) and discharge, but on a larger scale, they can be catastrophic if there is any damage to them, and the heavier nickle based batteries are not quite as reliable in the long run. The positives are that electric motors can be built in a number of ways just like internal combustion motors can. They can be built for lots of torque or all out speed.

But in another 10 years or so, when they are able to develop a "friendly" battery that doesn't weigh too much, and can cycle and charge quickly and often, you'll see way more all electric vehicles.

I don't think electric vehicles are ever going to be much more than toy. We can hardly supply enough electricity as it is right now to consumers. We already have blackouts in the summer when people are running air conditioners. Could you imagine everyone attempting to charge cars? Our electrical grid cannot handle it. Also, no one wants to build more fossil fuel fired plants, dams or nuclear power plants. Sadly, it is going to have to be something else to replace gasoline.

Right now, the best I see is all hybrid vehicles until the future.

The only place I heard about black outs is California... The next big movement, especially here in Arizona is going to be solar stations. There is a plant being built by APS called Solana, and with it's size it will be able to supplement somewhere around 70,000 households. Plus the place is going to be finished by 2013.

Yeah I'm kinda hoping for more of that instead of fully electric. Might ease the pain of the rising gas prices. I think prices would go up more if they lose a lot of business fast to electricity.

solar pannels on cars that charge all day on the trail? sounds okay to me ;)

and you can also look up cars powered by compressed air tanks. for up to 240 miles or some odd number :O now that would be bad in a roll over, haha. 500 psi tank hits rocks... LOL

anyways, this is easily a possibilty, but the hype about running out of gas is all that, hype. heck everywhere we drill, we dont get anywhere near 100 percent out of the well because its too "difficult" to get. so we still have all that to go back to, and clean up. plus eventually we will develop deep sea drilling and be able to drill on the ocean floor, in possibly the richest oil areas on the planet, and the oceans cover like what 75% of the earth? so thats 300% more oil than we have already gone through. Yea Im not gona worry too darn bad. technology will take care of itself. either way Im keepin my jeep forever :)

Check out Tesla Motors, their new Model S all electric car has a range of 160, 230 or 300 miles depending on options. 0-60 in 5.6 sec a top speed of 120mph. And can be charged in 45 minutes :eek: I'd say we are going to start seeing more electric cars in the near future, the battery technology is advancing at a rapid pace. I cannot wait untill these vehicles become more affordable, screw the oil companies :flipoff:

Of course oil prices would go down (supply&demand) but then electric prices would skyrocket :hide: And the higher demand for more electrical infrastructure means more work for me :thumb:

I wonder if the eco nuts realize how many electric cars run on coal.

I don't understand why companies don't design more cars like Tesla's which are super energy efficient and fit them with tiny generators to charge the batteries while you drive. I have a Honda generator, it'll run the ac in my toy hauler for 14 hours on 2.5 gallons of gas.

The oil industry doesn't operate on supply and demand, it's all speculation. I don't want to go getting off topic because that's a whole different discussion.

Hmmmm...could have something to do with the $100,000 price tag... :whistling:

That's weird, at around 3:10 into this video, there's a chart showing 22.5% of our electricity is from coal, and that coal is still cleaner than gas anyway.

Yeah, it seems like their mentality is; "we're losing money, lets up our prices."

Ahh, someone already pointed it out in the comments section of the video:

"Good stuff. A couple of points though.
1) I'm pretty sure the coal mix is closer to 48%."

His reply:
"@drivin98 - You are correct on the coal - I have had several people point that out. Apparently the website I looked at was incorrect. But it doesn't really matter because the point remains the same."

Yeah your wallet would be happier until the thing crapped out or you needed to replace the stupidly expensive battery, any of those hybrid cars are all in the same boat. Your good to go until something stops working, ever price out an alternator for a Prius? Or how about a new ECM? Fuel isn't the only thing you have to worry about when buying one of these vehicles. It's like a diesel, car or truck everything is good until they break down, when they do you'd better have deep pockets.

I think the ridiculously long warranty on the battery would negate the ridiculous cost of replacing it.

Jeep already built an electric wrangler:

Jeep Wrangler EV - First Drive Road Test - Truck Trend

Jeep EV: Rock Crawling The Electric Way


It destroyes the 3.8L and the new pentastar in power anyways, and who cares about fuel, right guys?! :hide:


-----------------

The Jeep EV Range-extended Electric Vehicle uses an electric motor, an advanced lithium-ion battery system, and a small gasoline engine with an integrated electric generator to produce additional energy to power the electric-drive system when needed. The 200 kW (268 horsepower) electric motor generates 400 N•m (295 lb.-ft.) of torque. With approximately eight gallons of gasoline, the Jeep EV has a range of 400 miles, including 40 miles of zero fuel-consumption, zero-emissions, all-electric operation.

-----------------------

It also produces max torq even at 0 rpm
