Why would there fail to be an aftermarket? There are lots of hybrids on the road already. If the battery packs do start to fail out of warranty, the niche need will certainly be filled. There are already D-Cell NiMH batteries available in bulk. A backyard mechanic could replace the entire complement of batteries for under $1000. -- Clarence A Dold - Hidden Valley Lake, CA, USA GPS: 38.8,-122.5

I doubt if the package is very efficient space (round hexagonal close packing vs. no intersticial spaces) or weight (each individual cell has its own no-value-added-as-far-as-energy shell) wise. Cost efficiency ($$/watt-hr) may also be lower, but you'd have to look at the numbers. In general, I would think larger and fewer number of whatever would be more bang for the buck, lb., cu. ft. Intermediate step towards that: UPS batteries. Bill Putney (To reply by e-mail, replace the last letter of the alphabet in my address with the letter 'x')

Hardly a suitable replacement, if for no other reason than that the charging circuitry would have to be modified. Perce

Maybe the Gen-II Prius is different. > Intermediate step towards that: > UPS batteries. Sealed Lead Acid? Different form factor? -- Clarence A Dold - Hidden Valley Lake, CA, USA GPS: 38.8,-122.5

Fluid drive trannys were simply stranded trannys that shifted eclectically, using a fluid coupling, similar to todays torque converter, rather than a clutch. mike "RapidRonnie" <rapidronnie(a)cbgb.net> wrote in message news:1184735641.115151.133290(a)o11g2000prd.googlegroups.com... > >> >> > I put the traditional CVT on par with the traditional fluid drive >> > automatic transmission with respect to complexity and number of failure >> > points, as well as its proclivity to fail. >> >> Don't mention "Fluid Drive" as prone to failure.
