Replying to: pf_flyer (Aug 12, 2009 2:54 am) My understanding is the Volt would get 45-50 MPG running off ICE after the battery is delpeted. I think the 40 mile electric claim might work out as well. Take a look at a similar PHEV test drive. They went over 50 miles electric ONLY and never went to ICE generation.   http://www.rasertech.com/media/videos/test-drive   This Raser Hummer prototype is estimated at approximately 33-35 MPG on ICE after battery depletion.

Replying to: wlbrown9 (Aug 13, 2009 12:33 pm) Volt is NOT a PHEV. It's an Extended Range EV. No hybridity to it. Only is propelled by one source - the electric motor. Never by anything else. Replies to this message: wlbrown9 (Aug 13, 2009 1:25 pm)

Replying to: larsb (Aug 13, 2009 1:06 pm) Okay. The Raser prototype is the same setup as the Volt. Some documents they refer to it as a PHEV others E-REV. It is like the Volt. Plug in charge, ICE generation, electric drive only. ICE only runs the generator. The test drive video shows them going over 50 without having the ICE come on. That was my point. It can be done... Real distance of course would depend on conditions.   Bill

Replying to: larsb (Aug 13, 2009 9:18 am) THE I.C.E. in the VOLT NEVER POWERS THE VOLT. It is merely a generator to provide power to the batteries.    Someone needs to do some homework.....   I'm fully aware of that. Tell me how a discharged battery, being replenished by an ICE, is going to generate MORE instantaneous power than the ICE can put out? If you are climbing that pass with a discharged battery, the ICE, through the generation of electricity, is the ONLY source of power. You cannot get more out than the ICE can produce if there is no reserve in the battery.

Replying to: eaton53 (Aug 13, 2009 9:19 am) The battery is not fully discharged, there is still a certain amount left as a buffer for hills. I wouldn't expect a Volt to be a hot rod when the engine's running but it should be adequate.   OK, so if the Volt battery is normally called discharged at say, 30% charge, then if you are going up a pass you still have some reserve power. But if it's a long pass (over the Rockies in CO, for example), you are climbing to 10K feet over tens of miles. So even that 30% charge is going to be used up and at some point you are down to max power the ICE can produce. It may not be a common occurrence, but there will likely be times when the vehicle is a dog in those types of situations. GM has not let anybody drive the mules on engine mode so those characteristics are unknown to the public at the current time.

Replying to: tlong (Aug 13, 2009 2:42 pm) Good points all, but GM has not indicated at all that the Volt will have ANY compromises in regards to power, hill climbing, etc.   We'll just have to wait for some independent road tests of the production version.

Replying to: larsb (Aug 13, 2009 2:50 pm) GM has never admitted that there were any problems with any of their cars, unless forced to do so by NHTSA.

Replying to: larsb (Aug 13, 2009 2:50 pm) Good points all, but GM has not indicated at all that the Volt will have ANY compromises in regards to power, hill climbing, etc.   Yep, they are really going to announce any negatives to help market the vehicle's capabilities. They are too busy touting their 230 mpg to talk about any compromises.

I don't think GM is going to hit the mark on the Volt. Price is going to kill this car. How many people are going to pay $40,000 dollars for this car? How many people can afford this car? Nissan announced its electric car can go over 300 miles per gallon and will cost thousands less than GM's Volt. How is GM going to counter that one? Ford is going to build an electric Focus, Toyota has its electric coming too. Price is going to be key for success. Mass production should bring prices down, lets hope...

Replying to: larsb (Aug 13, 2009 9:18 am) It'd be interesting to know the date of that press release, for a major publication (Popular Science, I believe) visited the GM Volt research & developement in an article about two month ago. What was, pretty much as you stated, is not now, as published in the article. It is an indication of why they never demonstrate the vehicle with the engine/generator functional, as it likely won't be what you hoped for. -- GR
