Lighter e-components allow more armor

Dear ARMOR,

On behalf of Bob Hoeltzel and myself, I wish to express my gratitude to you and your staff for the assistance in publishing our article on the in-hub hybrid-capable electric drive. We both realize that some editing to fit in the space allocated is necessary, but I would like to point out to your readers that one crucial figure was left out of the caption for Figure 2 on Page 46. This figure shows the mechanical pieces of drive train removed from the Stryker and replaced by the e-drive components, but an important fact is that the exchange of drive trains reduced the Stryker vehicles’ weight by 900 pounds. This simple exchange would allow 900 pounds of armor, for example, to be added to the vehicle while staying at its original weight. Not an insignificant advantage.
