GM product boss says EV development will cost less, hints at upcoming EVs General Motors' costs to make electric vehicles will drop by nearly a third from what it spends now making the Chevrolet Bolt when it launches the GMC Hummer pickup late this year. And GM will offer an electric Hummer SUV and another all-electric pickup beyond the Hummer soon, said Doug Parks, GM's executive vice president of global product development. Parks made the comments to analysts at the Morgan Stanley Auto 2.0 Conference on Monday. Parks said GM is moving faster to develop EVs now that it has the Ultium battery system, the flexible battery cell architecture that will underpin each of the new EVs that GM brings to market.
