Corvette Manta Ray: GM's bold new plan

A lot of what I read makes sense... Manta Ray versus Stingray name, an enhanced LT1 engine with both port and direct injection making at least 500 HP and a DCT transaxle only. However, I do not believe Corvette is ever going to be it's own brand. So therefore, I believe he has some good guesses like many of us do.

Can we get to the important stuff like:
- will my grandparents be able to get in and out of the car?
- how many sets of golf clubs will it hold?

Plus there will be plenty of time to order a new CT6-V with that engine. Production doesn't end until the end of next year remember. It's not like the car is cancelled before production even starts.

At least this jives with the engine order data that was leaked and the cad drawings. But I am not holding my breath that it is factual.

Possible that I overlooked it, but when I checked Cadillac's website a couple of days ago, I saw no mention of the 4.2L V8 engine being available in the current CT6.

The Dodge Hellcat has 717 HORSEPOWER & .....Passes emission standards parameters ....
So NO reason why an engine with approximately 150 LESS ..(if rated at 567 hp ) ...horsepower wouldn't pass emission standards parameters!!!

Also the hp-torque spread doesn't make sense: 520 hp & 485 torque when the current LT1 has only a 5 spread and Dodge has 10.
GM has never released actual numbers on engine performance until the actual reveal.
The CT6 V, which was supposed to get the Blackwing engine, will not be in production until next Spring. But it doesn't seem likely they will start production and then stop it quickly.

"I’m close enough to the inside to know the following about GM’s plans for the Corvette."
So this guy is not on the inside of Corvette or GM. There is no explanation of his sources or how he got his information.
Anyone with actual knowledge who breaks GM's information embargo is terminated immediately and permanently, period.
"If you don’t believe me then that’s fine, I wouldn’t either if I was in your shoes."
So now he is off the hook for any BS being spread. Got it.
"The C8 Corvettes at Nürburgring are the real thing."
Did anyone not know this? Why is he telling us this?
"A DCT transaxle is used in all C8 Corvettes, no exceptions."
Everyone knows this too. What is the point?
"The R&D investment in the DCT is said to be equivalent to that of both the manual and automatic in the C7 - they knew they had one chance to get the DCT right."
This is a nonsense statement: GM spent basically nothing additional for the transmissions in the C7 and if they built a DCT like the A8, they did not get it right. Should have bought a Getrag and saved time and money.
Bottom Line: This guy is a PR person or salesman who has heard some rumors.

Hellcat is supercharged, duh. The Dodge 6.4L makes 485 hp and 475 lb ft torque.
Also the hp-torque spread doesn't make sense: 520 hp & 485 torque when the current LT1 has only a 5 spread and Dodge has 10.
GM has never released actual numbers on engine performance until the actual reveal.

Then lets take a look at a measly 327 cu in engine back in 1964 in the Corvette.
The base engine was 250 HP with 350 lb-ft of torque. The highest output engine(still 327 cu in) had 375 HP with 350 lb-ft of torque. Increased displacement in the 375 HP engine is not why the horsepower increased 125 HP while the torque remained the same, as both engines had the same displacement.

So when and where will the Manta Ray be revealed?
Why doesn't Mr. unlimitedPower have a clue when he knows so many other details?
Joe, please. We both know that horsepower was measured differently in 1964. There is no equivalence to the numbers today. Why are you trying to BS me?

I hear ya, PCMIII, and if you're anything like me, age is "zapping my patience". But with age and youngins' that learn from us older "wise" folk...well, you know where I'm going.
