      This engine will be super cool in the new Corvette. Screw the low hood line
      Extend the redline to get 450hp will be in the ATS-V.

      Why would anyone want this engine in the Corvette? I guess if you wanted to mod it would be easy to jack up the boost, but stock for stock the LT1 is more powerful, torquier, probably sounds better and is likely lighter with better real-world fuel economy too

      It'll also have better response (no turbo lag), and will make a more consistent sports car motor since there aren't turbos that jack up the oil and air inlet temps.

      The only reason they even went with the TT V6 on the ATS-V is to play "me too" with the Europeans. The demographic that shops M3, RS4, etc are a bunch of ignorant Euro morons. They think the LT1 is the same small block that Chevy sold in a 57 Bel Air.

      There is no car that would be better off with the TT V6 over the LT1. Unfortunately, people's perceptions are why the TT V6 exist in the first place.

      Yes, that's exactly why they built the TT V6. To go "me too".

      Yeah, because the BMW's TT I6 has been trouble free. Those domestics just don't know how to engineer anything.

      Agreed. A lot of the new "turbo" technology is all about marketing.

      That is totally correct. All about marketing hype. This is likely to be a ridiculous engine, like their 2.0T that makes NOTHING better than their excellent 3.6 DI.

      The LT1 makes more power, and gets the same fuel economy they're projecting for this (1 less MPG city, same highway).

      So the benefit is..?

      smaller engine size?
      Aren't taxes in certain European countries based on the cubic inches of the engine?

      Shh don't tell that to Europeans! The CTS came up as a thread on my fitness forum and several European members came charging in denouncing Cadillac because the engines suck the cars suck oh and why ATS get terrible fuel economy compared to BMW? Oh right because American cars are fuel sucking pigs.

      Displacement has nothing to do with CAFE, and the C in CAFE stands for corporate. A handful of turbocharged Cadillacs is a drop in the bucket of GM as a whole.

      The Germans are trending this way, for CAFE as well as selling perk of better window sticker mileage. GM is just playing along.

      Turbo technology has come a long way since the 80's. OEM's use small turbos that have nearly instantaneous spool. Lag and throttle response is no longer an issue. Durability isn't really an issue. OEM tunes have been pretty conservative and intercoolers have improved as well. I'm sure that GM has an engineer or two floating about that can spec a proper IC core to keep IAT's in check.

      Pretty impressive specs... should be fun.

      I'm in the camp that thinks this engine is to meet current downsizing trends. Real world numbers might not pan out to be any better, but a turbo motor beats a NA V8 in government economy testing pretty much every time.

      The ATS isn't as good as its BMW counterpart in terms of fuel economy tho. They have a valid point. From what I've read, all the Cadillac new models are a little weak when it comes to real world economy.

      The rest of their argument is pure opinion... I know quite a few people that have owned Cadillacs and say they are the worst piles of crap built... I also know some owners who had great luck with even some of Cadillac's worst models. (500k kms out of a 1st gen STS with minimal maintenance/repair and other stories like that).

      Not if the NA V8 is also DI, like the forced-induction that it is compared to.

      This won't go in the Corvette - that's V8 only. It will probably see some action in the entire Cadillac line, and I wouldn't be surprised to see it in a version of the Camaro, the next SS, and the rumored RWD Buick.

      Transverse applications, European-market applications.

      Personally, I tend to agree with Dan Roth over at Autoblog that versions of the small-block could and should be used to power the entire Cadillac line, but....

      Bingo... displacement taxes. A 6.2L is uncompetitive in a lot of Europe because of poorly conceived tax structures.

      Buick/GM also has a pretty long history of force feeding V6 engines.

      The supercharged 3800 Series V6 was damned near standard on all mid-sized to full-sized GM sedans/coupes for most of the 1990s.

      as much as it hurts TCL to admit it, this is one area GM has done very well in.

      . Throttle transitions still result in noticeable lag, even with small turbos.

      I bet NVH was a consideration as well. The V6TT will be significantly more quiet (inside and outside) than the LT1 would. This makes sense, considering the demographic of Cadillac. Of course enthusiasts would probably prefer the LT1, but I get it.

      this is true, but direct injection and more aggressive timing has changed this from seconds to tenths of seconds.
