Corvette Z06 to be renamed Z07, come with twin-turbo V8? - Autoblog

I like this idea, 600HP TT corvette would be awesome, and something new to the Corvette brand.

 

I think there needs to be something between a $55k base car and a $100k uplevel version. I liked the base / Z06 / ZR1 arrangement. I also liked the high revving (and large displacement) N/A engine of the Z06.

 

Agreed on all points.

 

I agree, maybe they will do an "LT4" to this generation of LT1 (although I hope they call it something else since I already think having two LT1s 17 years apart is too soon).

 

The Z51 cars making the rounds at the various publications sticker for about $70k and are putting out C6 Z06-like performance. There's your Z06 replacement - the Z51.

 

Just doesn't have the same allure without that big ol honk'n 7.0 liter V8

 

Which is why it definitely isn't accelerating like the Z06!

 

Torque curve is about the same on the LT1 and LS7. I will me the big 427/7.0L V8 though. It was cool to have such a large displacement in the Corvette. I'm glad they are going to keep that engine alive in the Z/28 for 2 more years.

 

I like the idea but think they are putting it in the wrong model.

I think the ZR1 should be the big HP Twin Turbo V8.

Keep the Z06 or Z07 N/A. I like the idea of a higher revving more displacement LT engine.
Slotted between the base/Z51 and the ZR1. Which IMO should push the envelope even further in the C7. 700-750 hp

 

Unless I am badly mistaken a 7.0 Gen V will probably not happen. I read a bunch of stuff that the 4.125 bore made it difficult to burn the charge competely enough to pass emissions. As those standards tighten, it will get more difficult (perhaps impossible). I hope I am wrong, I want to see a 7.0 Gen V, but would not hold my breath.

 

I'm sure with direct injection they would have much more control over the combustion.

 

Hmmm... I suppose so since DI wouldn't let fuel rest in dead areas of the combustion chamber (like the gap between the cylinder wall and piston crown) or in a quench area however slight it may be.

That's the problem with large bores, increased dead space with conventional fuel delivery systems. IIRC that's one of the reasons the LS1 had a less than 4" bore.

 

According to GM press releases, there are plans for four Gen. V engines. The 4.3L V6, 5.3L V8 and two versions of the 6.2L V8. I assume the two 6.2L are the LT1 and the coming LTx TT 6.2L. Or would the other version of the 6.2 just be a detuned version for trucks?

 

The L86? It is rated at 420hp & 460tq

 

That press release was referring to engines built at the Tonawanda engine plant. Yes, the truck 6.2 would be the remaining variant.

With the move of the performance build center to Bowling Green, I assume all higher performance Gen Vs will be built there.
