IMO, rather than E-Flex Sigmas you'll be seeing LS w/AFM powered 2-mode Li-Ion Plug-In Sigma and Zeta Cadillacs.I completely disagree. A V8 is not a requirement, would it be nice to have for a few years - sure - but Cadillac doesn't have a 7/S competitor, and thats where a V8 might be "required."
GM decided it wasn't worth the cost, and if they are putting the money towards advancing a E-Flex Sigma by a year, thats a good decision.
These old fashioned ideas of whats "needed" for any type of car are outdated. There are now many ways to make lots of power - and all have advantages and disadvantages. Its all going to be turned on its head within short order anyway. Just pretend electric motors are like DVDs and direct ICE power is like VHS.
Lets judge powertrains on power, torque, NVH and fuel economy - not some romanticized obsession with the past.
They've got the jump on everyone when it comes to powerful hybrids (the Lexus LS600h is a joke) and when those powertrains find their way into luxury cars they'll be the Standard of the World for power and fuel economy.
They can probably do this for less than the Germans charge for just an engine.
Speaking of the Germans, despite their investment in it I've read that they think the 2-mode isn't good enough (Translation: Not German) so they're tweaking (Translation: Overcomplicating) it. So who knows when we'll see it in any of their stuff or if it'll work great like I-Drive or COMAND (Translation: NOT!).
