GM is launching three hybrid systems next year.
  1. Voltec
  2. Two mode for sedan and FWD small suv applications
  3. Second Generation BAS
I am concerned for Ford, and sort of happy for GM becouse with the second generation BAS, its said to provide 15% to 20% improvement in fuel economy and that is right into fusion hybrid territory for malibu. ( currently 34 mpg highway 24 mpg city) and suddently you are talking 39 mpg highway and 30 mpg city for a meager $1500.00 cost, comparted to the $10,000 or so premium you pay for a full series hybrid.
Generally, Ford should be concerned and look into developing on licensing GM's Mild BAS system.
In its third generation (2015) this system could easily match Toyota Synergy system.

So far no one has an advanced system anything close to two mode system, and no one has voltec technology not to mention they GM just miniturized their hydrogen drive to the size of a normal 4 banger system and think it will be commercial relatively quickly (2015)

If folks are not careful, GM is going to dominate the electric vehicle market since they have a multi pronged approach to the whole market.
