The CEO of Cadillac did confirm today that the LTA engine will not be used by any other GM brand. He went even further, stating "I think Corvette wants a different kind of character". Carry on. |

The article did say however: "Still, even though the Cadillac boss says this specific engine won't go to Corvette, it's hard to not think some version of this engine, perhaps in a different displacement, could find its way under the hood of the Vette at some point in the future." So, there could be a 5.5L version of this engine in it's current configuration, OR it could be a 5.5L DOHC TT non-hotV. Meaning it would be in the more traditional setup with the intake side in the V, and the exhaust and turbos on the side. Which would coincide with the CAD drawings that we saw that were supposed to be from the mid-engined car. Hope they tell us something more at the NY Auto Show coming up. |

There won't be a 5.5L version of this engine, the bore spacing is even smaller then that of the Coyote engine so realistically speaking 4.5L is the largest displacement this engine will see.
The LT motors use a 4.400 inch bore spacing (going back to 1955 small block chevy's have had that), the Coyote engine has a bore spacing of 3.937 inches which is why you don't see 7.4L Coyote engines. The 5.8L trinity engine used a 4.125 inch stroke to get 5.8L, while this new engine has a 3.779 inch bore centers. If they gave it a 3.5 inch bore and a 4.125 inch stroke (don't know if this engine can go up that high but I doubt it) then you would have a 5.2L engine. With a 3.5 inch bore airflow will suck and with a 4.125 inch stroke this won't be a 8,000rpm on a production engine, this engine was made to be a small displacement twin turbo non performance engine from the ground up. Going with a much smaller block then lets say an LT motor allows the engine to have good packaging and lower mass (529 pounds roughly the same as the LT4 engine). I remember a while ago BMW having major issues with the hot V setup, it is too much heat in the engine to be driven hard on a race track. CT6 V sport is the perfect application for such a layout.

In an interview with Hagerty, Al O. strongly implied that the ZL1 1LE was not the end of the Gen6 Camaro lineup. And he said that they are looking at any available HP. And he said they want to get under 7:00 at the Nurburgring. Seems to me he is hinting at an LT5 Z/28. I'm not convinced there will be a Gen6 Z/28, but if we do, I think it will not get anything they are developing for the mid-engine car. I think Camaro will get that in Gen7. But what do I know... |

I haven’t seen anything, which would be very surprising, if they were there.

If I had to guess, maybe they had a window to go for a recorded lap with a ZR1 EDIT Looks like it was Camaro there but doesn't sound like for anything major |

as cool as I think it would be I will wait and see what the ZR1 does at the ring before I get my hopes up about a Camaro doing a sub 7

Think the ZR1 will get there if its a track car 100 more HP and 300lb less then the ZL1 is a lot.
