    "that "new hybrid system" ..."

    ... is actually the second generation of GM's mild-hybrid Belt-Alternator-Starter system, with lithium-ion batteries and a stronger electric motor that allows a small amount of electric-only running on startup. It's broadly similar to Honda's IMS hybrid system (Civic Hybrid, 2010 Insight). If memory serves, the technical details for BAS-II were released at the 2008 Geneva show.
