Well, since the regular version is RWD, I think it's safe to assume this version will be too. It'll probably come in auto since I don't think they have a manual tranny for the V8 yet. At least, not in the US to my knowledge.
I think it's a hit. Just a single though. Definitely not a homerun. It's a bit too little, too late. Nothing special about it other than Lexus'/Toyota's legendary reliability. Least the Caddy CTS-V has interior room to go with its monster power. Maybe if they keep it under $40,000 it could be a big hit. I mean, regular 330i or V8 IS could become a real dilemna kinda how teh G35 is serious competition due to its power and price advantage.
