Yeah, what's up with that ? I mean the first time they re-used the engine designation it was kind of cool. They resurrected the name of a pretty potent small block that was actually the last decent small block used in the corvette for 20 years. The 20 hp increase in power with the addition of direct of injection is kind of a let down, but I'll bet that within a year or two another even more potent base engine will pop up. They tend to do that to keep interest up. I am still undecided on the looks, but the performance is improved again.

Stingray is back as well! Now with Direct Injection!

Do I detect a hint of sarcasm there ?
The direct injection stuff is pretty cool honestly though. But if they wanna revive the stingray again they should try to add at least some styling cues from the stingray. That's what I'm not real fond of with the looks. It looks like they ran out of ideas once they got to the tail and pasted the ass end of a camaro on there or something. It just doesn't mesh with the rest of the car if you ask me. But I'd still sell my left nut to have a new vette. I mean at the end of the day they are still an impressive machine and they outperform anything else in that price range.

At the Detroit car show they had a good cut-away of the new engine. Unfortunately we forgot to get a close up picture of the combustion chamber. The pistons are domed to work specific with the direct injection. Some pictures I saw of the new engine had O2 on each cylinder but they are not using dedicated cylinder o2 for production. With DI some engines are injecting fuel during exhaust stroke to increase cat and o2 warm up times.
I have a bunch of pics of the internals of a direct injected 3.6 that I haven't gotten around to uploading and adding notes to. When I finally get around to it I was planning on starting a thread for those interested in learning a little more about direct injection and whatnot. So, keep an eye out if you're interested.

Seeing the pictures would be great.
I misspoke on the other post. The goal of injecting at the end of power into exhaust stroke is to decrease cat and o2 warm up time.
