It is not exclusive to the Cadillac. It is pioneering on the CT6, but as per our other thread, it will be on our 2020 ME Corvettes.

That power plant will truly bring the Corvette into "World Class" status. The Corvette will compete with the other supercars at a substantially lower price point, and kick their *** on track !!

Kinda hard to believe that the ME would be down 200+ hp from the ZR1 and be expected to be competitive in the performance world class cars.

If this is one of the engines to go into the ME. it will probably be pushing more Hp in Corvete trim than in the Cadillac. Based on other reporting this could be the mid-level engine and would be married to the higher performance Corvette (Z06) or whatever it will be labeled.

Great times are still coming for the Corvette moniker and I love watching this car become better and better with each generation.

A few things we want to remember.

*The 4.2L is the smaller sibling to the 5.5L — which is also a 32V, DOHC, TT, V8 and the latter which could develop up to “an estimated 850 HP” (source: Markit Engine Forecast);

* ZORA is not coming until 2021 or 2022 — at which time a comparison of ZORA and the ZR1 would be warranted — though for the reasons below, it might not take until ZORA arrives for this to be a great competition;

* The engine in a ME is roughly 2” closer to the pavement, e.g, a much lower center of gravity than a FE with consequent better handling;

* The engine in a ME is roughly located right over the rear wheels, i.e., giving much greater traction coming out of a corner than a front engine/rear wheel drive;

* As noted in today CT6 press release, the 4.2L weighs less than the 6.2L. Couple this with probable other weight reductions in the ME, we could get 4.2 L, 2020 ME Corvette weighing perhaps 100-150 pounds less than a FE C7.

Put all five factors together, and sorry all FE lovers (and I am one), the ME will be, by time ZORA arrives, be more competitive in the world of performance sports cars.

All good points.
The driving dynamics of the ME should be dramatically different too.
It shouldn't feel or act like the FE C7.

BTW, when is your ZR1 being delivered and what color will it be?

If you have ever driven a 911 type Porsche, then u understand how the steeply slopping hood(frunk)gives u a visual connection with the road u simply do not get w the Vette. The ME will bring that to the Corvette world. Coupled w the lower CG of the ME platform and overall more neutral balance, the ME Corvette will make the FE look like an anachronistic memory in the evolution of this American icon. It will make obvious how we have all been muscling that front end around all these years.

The 6.2 DOHC TT is still in the works. Watch for it.

Check out this ground clearance. 5" for major components is the industry norm, no different for Vettes. Our roads are in bad shape. With a dry sump, you can bring the engine down lower but not below this for practical reasons. C7 is as low as you dare. Since C4s, Corvette have had two massive rails under the car to protect the engine.


Both counts are not true. The ME engine is in front of the rear axle and not even roughly above it. The input shaft of the gearbox/transaxle, determines the ground clearance of the engine. I posted pictures of the Ferrari TR engine above the axle on top of the gearbox.

That engine is not going in a Corvette.

A close-cousin motor may be going into a future Corvette. Source: Markit Engine Forecast which specifically lists a 4.2L, 32V, DOHC, V8 going into a Y2 platform 2020 Corvette (whereas C7’s are Y1 platforms).

What is the bore and stroke of this so called 5.5L variation of the 4.2L Cadillac engine?

What is the diameter of the flywheel/flexplate on the 4.2L Cadillac engine?

What is the weight of the 4.2L Cadillac engine?

What is the weight of the ME Corvette?

What is the center of gravity of the C7?

What is the center of gravity of the ME Corvette?

Since you seem to know those simple facts in order to make the statements of fact that you have, lets get your facts on paper, so we can see if they are really true facts when the ME Corvette is actually released.

And, so far, the C7 has not been available in a RHD configuration from GM, and I doubt it will ever be available in a RHD version from GM.

I think the Boss man at Cadillac just did the same thing. He put the "stop with the BS" to the 'experts' who are claiming the 4.2L Caddy engine is THE engine for the ME Corvette.

LHD cars are not allowed into Australia. $30 000 and your Vette can be made legal with some Holden parts and other stuff.

Keep in mind that technically, he didn't say it would not be the engine for the ME. It's just definitely not going into a Corvette.
