Replying to: tpe (Sep 24, 2008 11:31 am) Since the ICE/generator/motor path is around 80% efficient, I don't see how this 50 MPG is achievable in a 3300 lb Volt at battery depletion. (Normal transmissions are around 95% efficient or higher.) The 50 MPG might be possible if the ICE: 1. ICE shuts off below 20 mph (with time hysteretic logic added). 2. Battery helps feed the motor during acceleration or up hills. 3. ICE delivers some small amount of charge to the batteries, along with regenerative braking. Without all the above, you might be able to get 30 MPG or so, not anywhere near 50 MPG as GM has so far stated. This would seem to contradict some of the latest statements saying that the ICE doesn't recharge the batteries, although that probably only means the ICE won't bring the batteries to a full charge, providing sustaining charge only to keep the batteries at 30%.

Replying to: eaton53 (Sep 27, 2008 4:06 am)  "what’s really interesting about the iMiev right now is that Mitsubishi has just released a price figure of what $37,496 US, which is about $2,500less than we often hear talked about as the price point for the Chevy Volt. Despite the similarities in pricing and release date, the two cars are very different beasts. The iMiev is based on a current Kei-car produced by Mitsubishi for Japan, and has a 47kW electric motor powered by a 330-volt lithium ion battery pack. The car will have a top speed of 80 mph and an all electric range of about 100 miles. Charging will take place via a normal power outlet and should take about 14 hours to completely charge the battery, though there is all a 220V charge option, which only takes 7 hours." I am not sure why the obsession against the range extender. My current car gets 25 mpg on the road. I drive from portland to seattle about once a month. Almost all my other daily driving is under 40 miles. So... I can spend my $40k on a battery only EV and keep my old car for seattle trips...sorry, I am not going to double or triple my drive time to get to seattle waiting for a recharge. So 400 miles r/t  25 mpg (generous) I would use 16 gallons of gas. With a Volt I get 50 mpg minus the 80 plug in so I use ~5 gallons. I would actually use more gas per month with the full EV. And yes I could buy another higher mileage car, but that is another ICE on the road, no? And what about all the oil and etc in the manufacture and shipping and support of said vehicle...not to mention the cost. Another thing good about the Volt et al (just read dodge is in the same game) is that it is speeding battery research and maybe more importantly, scale manufacturing of the batteries so we can see if price will be such that BEVs can gain advantage.

Replying to: peralta (Sep 27, 2008 1:47 pm) I can change early 2000's to 2003 if that is better..but I think it can be assumed that they started looking into it in 2002. |

Replying to: reddroverr (Sep 27, 2008 10:34 am) Is the iMiev sized for smaller (on average) Japanese people? Looks small in there. Remember the old Datsun B210? The only friends of mine that could fit in that Japanese-market sized vehicle were my short friends. Usually they have to add a little room inside for it to make it in U.S./Canadian/European markets. The Volt will be sized to fit up to a 99% percentile American and enough width to prevent it from being a roly-poly hazard. I.E, a real car.

Replying to: coldcranker (Sep 27, 2008 4:34 pm) It is pretty small..133" end to end..compare that to the 3 door Yaris which is 150 inches. The 100 mile range is for ideal conditions... no AC or heater. One tester found about 60 to be safe running the heater. Might be an ok commuter/in city/second car for some folks. Personally, anything below a Yaris size is out of the question for me. http://www.autobloggreen.com/2008/03/21/new-york-2008-autobloggreen-drives-the-m- itsubishi-i-miev-w-vid/ http://www.edmunds.com/apps/vdpcontainers/do/vdp/articleId=124867/pageNumber=1 |
