At the D7E's official introduction event in Peoria, Cat representatives spoke for the first time of the electrically driven bulldozer as a “hybrid-electric” tractor, and candidly discussed the 20-percent premium it is expected to draw over the D7RII it will soon replace.

Eighteen pre-production D7E hybrid bulldozers built on Caterpillar’s line in East Peoria have amassed thousands of hours in customer operations. Cat expects D7E production to begin in October, with some specialty adaptations (a solid-waste version, for example) to be introduced in spring of 2010. Production of the D7RII is planned to end in the middle of next year.
