How? It's an exhaust waste energy recovery device. Ordinarily, the reduced compression ratio could harm BSFC down low to allow boost up high, but if the Volt runs at a near-constant load, they should be able to tune it for better efficiency with a turbo than without.
I believe their decision came down to cost and NVH, but primarily NVH. That's unfortunate.
