[quote]QUOTE: Originally posted by oltmannd [quote]QUOTE: Originally posted by futuremodal [quote]QUOTE: Originally posted by daveklepper Hybrid cars are practical, the cost vs conventional vehicles is not a huge increase, and there really isn't any reason for not using them across the board. So fuel economy regulations happen to make sense to me. [/quote] Typically, electric-hybrid vehicles cost $6,000 to $7,000 over the same size conventional car. So at an average low ball figure of $15,000 for a small car, a hybrid will cost over $20,000, a 33%+ increase, fairly substantial. Now, if we're talking about using hybrid technology in an SUV (and assuming the same hybrid cost premiums), then we can take a $25,000 SUV and increase it to $30,000+ for a hybrid SUV, then it's only a 17% price increase. My bet is that the cost increase for a hybrid SUV will be porportional to that of the smaller models. The real transport breakthrough with hybrid technology will be when it is incorporated into trucks on a large scale. Can you imagine the increase in ton/mile fuel efficiency when hybrid 146,000 lb trucks are out there? What will that do to shorthaul and medium haul rail dynamics? [/quote] You really have littile idea how hybrids save fuel. They would make almost zero difference in an over the road truck. [/quote] Hybrids save fuel by allowing regenerative braking to produce electricity for storage which can be drawn on later, that is their big feature. Other than that, the system of batteries being recharged by the prime mover when needed really doesn't save that much over direct drive systems. An over the road truck will spend as much time in regenerative braking as any other vehicle.
