Replying to: hoosieriusb (Sep 08, 2008 7:59 pm) Let me add to this one: I bought an '82 Citation.,.brand new, One its first outing, the thing died right in its tracks in the middle of nowhere. Electrical wiring problem. It was in and out of the shop. The worst car I ever had! My next car was a '84 Camry and I haven't looked back since. I drive an '08 Camry Hybrid today..great car. I'm open to the Volt, though. GM makes far better cars than they did in '82. I appreciate the opinion of the poster who anticipates Volt technology in other GM cars at lower prices. I hope that happens. $40,000 is too rich for me. I also remember a time when $20,000 for a car seemed out of sight. GM could win back my business with the right priced car using Volt techology.
#23 of 24 Technical Question, not yet addressed by vonoretn Apr 25, 2009 (5:05 am)
As a retired automotive engine engineer, I have a question that has not yet been addressed. Say you have driven your car past the initial 40 miles, you are on a trip, and you are coming into the Rocky Mountains for a long climb. We have this little 4 cylinder engine to get us up the mountain, a job that takes at least 3 times as much power as traveling on a flat road. The engine starts out with a 30% efficiency at creating mechanical power from gasoline. We now have the added inefficiency of at best 70% of converting mechanical power into battery charge, then converting battery charge into driving the wheels is another 30% loss. That puts us at a 15% overall efficiency for the gasoline engine in the Volt. Is it going to be able to make the long climb, and how could it possibly compete fuel economy wise with a 4 cylinder engine connected directly to the drivetrain, like in a Ford Hybrid?
