ev99, Just FYI, Jack also did an EV Cobra and did a comparison test between two sets (widths/brands) of tires for the Cobra.

Additionally, Ron Adamowicz's "Warp Factor III", an EV "camaro" dragster, uses A123 pouch cell pack. At last month's EVCCON, Ron experienced really deep voltage sag during a 1/4 mi. run (~80V sag on a 200V pack if I recall correctly, don't quote me on that). The speculation is all the individual connections between the pouches may be causing a high "internal pack resistance" resulting in large sag during high current runs.
