General Motors is to finish building the first Chevrolet Volt battery car using production tooling today, at the Hamtramck, Mich., factory that will begin regular production of the radical electric car in November.
The pre-production Volt will be kept for GM testing. Such practice runs are tense for automakers. They show whether the tooling is designed correctly, the factory laid out properly, the workers trained sufficiently. The interim before regular production this fall gives GM time to make changes, though major hiccups weren't reported.
"Never seen a first, pre-production build go as smoothly as this one," said Andrew Farah, Volt chief engineer.
