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.

A quick glance at Pontiac's (rumored) future product plans reveals just how much fuel prices have affected plans for an all rear-wheel drive lineup. Let's see, we've got the Solstice and the G8, and, um... that's it. Sure, we're expecting the G8 ST soon, but the El Camino-come-lively will never sell enough to keep bean counters happily sliding their abaci beads in their cubicles. The Solstice also plays to a relatively small crowd, so its future could be up in the air, as well.

As for the rest of the brand's lineup, the Grand Am G6 will remain on the same front-wheel drive platform for the foreseeable future as there's just not enough funds to switch it to a rear-wheel-drive platform. Meanwhile, the G5 is tied to the Cobalt and the future Cruze from Chevrolet that uses the FWD Delta platform. The Vibe comes from Toyota and is based on the Corolla's underpinnings. Please, don't get us started on a possible Aveo-based subcompact from GM's "Performance Division". As our esteemed editor says, "So sad, G8 rules." Indeed it does, and it may be the best we'll get from Pontiac for a while.
