#5 of 14 Electric cars by throttlecat Apr 18, 2007 (8:50 am)
How come some computer nerds in California can build and sell an electric car that goes zero to sixty quicker than a Corvette and get up to 300 miles on a charge? Major car companies keep saying maybe someday we can build a electric car but not now. Replies to this message: larsb (Apr 18, 2007 9:03 am)

Replying to: throttlecat (Apr 18, 2007 8:50 am) Well, other companies could do that for $100,000 a pop just like Tesla did...... Problem: not enough market to make that car profitable enough for the corporate boards to give it a go..
#7 of 14 Comment on Hybrid Pickup by jarleigh Apr 18, 2007 (1:16 pm)
Increasing the MPG of a Pickup from 14 MPG to 16 MPG is roughly a 14% increase, this is the same as increasing the fuel economy of a car that gets 35 MPG to 40 MPG not 51 MPG. 51 MPG would be almost a 50% increase in economy. Replies to this message: mithridates (May 23, 2007 3:44 pm)
#8 of 14 No mention of Pneumatic Hybrids by escape15208 Apr 19, 2007 (6:34 am)
Probably because they arn't being introduced into passenger cars. The system utilizes a gas compression system to store energy during braking. When accelerating from a standstill, the pressure is released, aiding in acceleration. The technology is being used by UPS on its urban delivery vans and they plan to roll it out on their entire urban fleet over the next few years. The system allows use of a smaller engine for better fuel economy. A oversight on Edmunds part; there have been several articles on the techonolgy, which is far cheaper and less complicated than battery hybrids, on NPR.

What about hydrogen powered cars? Any info on that Dan?

Replying to: jarleigh (Apr 18, 2007 1:16 pm) Jarleigh the author merely said that going from 14 to 16 saved as much gas as going from 35 to 51, not that the percentages are the same. For Example 10,000 miles at 14 mpg is 714 gallons used. 10,000 miles 16 mpg is 625 gallons used. 714-625=89 gallons saved. 10,000 miles 35 is 285 gallons. 10,000 51 is 196 used. 285-196=89 for the same cost savings. That is why going from a civic to a prius doesn't save nearly as much gas as going from a camry to an V8 truck. The 10-12 mpg gallon trucks are what kill us in terms of national consumption.
#11 of 14 Turbo diesel hybrids - D by texases Jun 07, 2007 (10:33 am)
I know people love to talk about turbo diesel hybrids, but their high cost eliminates any ability to save money. And don't compare it to a normal gas engine, compare it to a turbo diesel, where you've already gotten the lion's share of the benefit. You can't spend another $3000 and have it make sense.
#12 of 14 Electric? by sinna46 Jun 08, 2007 (1:04 pm)
What about pure electric? Sure there are not many available now, but isn't it something to at least think about?
#13 of 14 Turbo Diesel Hybrid by galvang Jun 09, 2007 (8:52 am)
Volkswagen and other German manufactures have small turbo diesels in production for quite awhile and they are relatively inexpensive, such as Volkswagen Jetta, Passat and others. I just do not beleieve the price hike of 10K in marring the two existing technologies to achieve the double whammy effect of fuel economy. They may be less reliable due to more parts but integrating the two technologies should not be that much. Replies to this message: texases (Jun 09, 2007 1:46 pm)

Replying to: galvang (Jun 09, 2007 8:52 am) No, should be more like $3k, but when you're starting at about 45 mpg, $3k is very difficult to pay off.
