When the Chevy Volt goes on sale in late 2010, it may be joined shortly thereafter by other GM-branded series hybrids using the eFlex architecture. But after the General's bread-and-butter bow-tie division, which brands make the most sense to get their own Volt? We've already seen a Cadillac with underlying eFlex technology, and GM's luxury arm could charge higher prices to offset the cost of the expensive powertrain. After Cadillac, Saturn might be a good bet considering we've already seen an eFlex-based Saturn-branded FlexStream concept.

Susan Docherty, GM's North American vice president of Buick, Pontiac and GMC, thinks GM's driving excitement team is a natural fit for a Volt-like hybrid. Her reason is that the Pontiac brand can attract a younger crowd that readily accepts new technology and cutting-edge design. We're not so sure. If Pontiac is supposed to build excitement, how does that jive with a heavy battery pack in a car that's engineered to save fuel rather than go fast? Then again, nothing says instant torque quite like an electric vehicle. Dealers who bought into building combined Buick, Pontiac and GMC stores will want at least one vehicle in their showrooms based on the eFlex architecture, though, and Pontiac makes more sense than Buick or GMC.
