Lets hope not considering GM intends to do that will all their lux cars shortly (they gave it a go, but didnt work out to well in prototype cars) but they think they perfected it now.
Northstar powered cars have something similar, yet its used in situations where the engine tries to save itself. Fuel gets cut off to 4 cylinders and its called Limp Home mode.
As for styling, the new 300'* are oh so very "love or hate" cars. I personally hate the new styling. In my book the GXP looks far and away a better car. Had Chrysler dropped the V8 HEMI powered RWD into the 2000-2004 300M, I'd be all over like flies in ****
