Here is the issue with that, that 4.2TT engine is the same weight as the LT4 (I know they say that its lighter but they say it is 529 pounds and the LT4 was stated as being around 529 pounds so what 5 pounds lighter). If you had to pick between two engines that weigh the same but one makes 550BHP and the other makes 650BHP then which engine makes more sense for the Z/28?.
It also uses a really small block so you won't see 6.2L from this engine and probably not even 5.0L from it so don't expect much else from this engine sans higher boost for more power. Last edited by doc7000; 03-22-2018 at 07:22 PM. |

And they(Al) made a very prominent point last gen that the Z/28 must be N/A so this particular engine would be a no go.

I doubt it. Caddy has mentioned they want proprietary engines in their cars. Not just any drop in that GM makes.

Once again GM falls short in power vs the competition. Will they ever set the bar rather than almost reaching it? If this is the engine for the mid engine Vette it isn't very impressive.

How is this engine falling short of competition? Can you name those competitors? Also, this is not the only engine going into C8.

This is supposed to be Caddy exclusive. The Germans have small TTV8s, which is why Caddy wanted one. the Vette will probably get something different.

I went back and read it again. You are correct, it IS on par with the imports in it's class. I must be getting old. It still won't work in the mid engine Vete which should be north of 800 hp.

I think the 4.2TT is the perfect standard motor in a mid engine corvette priced at around $70 k starting price.

Not enough power for making a statement. If you want a mid engine Vette why under power it?

The Audi R8 is talking about going to TT V6 instead of V8 for the base. I think an small displacement, 500 + hp, TT V8 would be just fine to start with. Plus, look at the torque output, 627 lb/ft is really going to get you moving. A Mercedes E63S is ~4,500 lbs (w/ AWD) and that car hauls the mail for sure. Imagine in a current C7 at 3,500 lbs....
