Great Fund texel. You have asked the key question, will any of it get into an ME 2021+ motor? Even thought it bears a date of just 11 days ago, it was originally filed in November, 2016, so perhaps???

Might you also have access to subsequent pages (if there are any)?

Thanks Ammo. I like learning more info. Now to dig in on the remaining eight pages.

I'm surprised that GM and others don't adopt the Porsche model of offering a ton of really expensive options. Have you guys ever gone on Porsche.com and built your car? It's pretty fun when you have a zillion options, most of them just silly and unnecessary. It's also fun to see how much you can inflate the base price (a lot!).

elegant

Per several previous posts, we will be getting the Porsche plan, i.e., the option to specify tons of options is coming in the 2020 ME. Whereas the ME’s entry price will be surprisingly low, the total if every option box were to be checked will be in six digits IMO.

I hope you are correct and I’m am also hopeful of the prospect of buying an ME Corvette with very few options except for a folding hard top. Having owned a new ‘65 C2 Vert, 4spd, 300hp that was enough to make me happy. My ‘14 C7 is a 3LT Auto Coupe which is great but in hindsight overkill for me. I’m a cruiser but for $300 installing the Z51 Bars was a great mod.

My fear is that GM bundles options in a way that the HT has to have a long list of other options that has to be included ending up with a significant increase in price. Such as HT only for a 3LT or even a 4LT build.

P.S. These C8 Threads are increasingly revealing important tidbits of information and reasonable speculation. Hats off to many of you contributors to this effort. Keep it up.

The GM patent application seems similar to the Mahle TJI system used in F1 and Japan's GT500 racing series .. up to 4 points more compression..... https://www.mahle-powertrain.com/en/...-jet-ignition/

Bill Dearborn

Isn't that patent application just a method of delivering a gasoline engine that is able to use compression ignition under certain operating characteristics? In the executive summary it talks about spark ignition engines being configured to run in a compression ignition (or auto ignition) mode. This lets them use very high compression ratios to get more efficiency out of the engine similar to a diesel engine but without using diesel fuel. Using compression ignition you remove the throttle restrictions as the engine will operate in its most efficient mode which is wide open throttle and power will be modulated by fuel delivery like a diesel engine.

Don't want to be the mechanic charged with changing the plugs on that engine.

It can't be turned off by guys like Pobst (there's no learning curve). It gets one on the most of the competition.
There aren't any negatives! Add this to the higher tech versions.

Still want that base race car light Z51 version though! 7,500 RPM TT LT1 variant. Simple LS diff and iron brakes. Big track options from the get go!

After viewing a current side view image of the ME I scaled the wheel and tire size relative to the wheelbase(front hub center to rear hub center). Using the ratio and proportion theorem it calculates out to almost a perfect match of the wheelbase 106.7" of the C7 FE chassis wheelbase. Most likely both FE and ME have matching wheelbase measurements to fit the new Skillet System on the Line. Elegant brought to my attention the advantages of the skillet system process and it makes logical sense to have identical wheelbases of both for manufacturing efficiencies of both configurations.

elegant

Well done skank! It is nice that we earlier got hard info on which you based your calc’s on, i.e., the diameter of the ME’s real wheel is definitively known as 27.2”.

Of course, as you and I and FVS have communicated and agreed, all scaling is based on our assuming that that the ME that is being scaled off is 90 degrees to the camera, not 88 or 93 degrees.

FVS has previously scaled the ME’s wheelbase as per the below picture. His scaling comes up with a very similar wheelbase number of 107.8” — again within scaling margins. Thanks FVS!

skank and I also discussed the possibility of an alternative, with the skillet’s anchoring system possibly being instantaneously adjusting if/as necessary if GM decided that it needed the ME’s wheelbase to be an inch or two, maybe even .1” different from the FE’s.

skank

Yes Elegant, I do believe the skillet photo appears to show it has adjustability. You can see the rear wheel L shaped unit is bolted down and the front appears to be channeled and able to slide forward to fit any measurement. I still think there must be efficiencies to keep both FE and ME as the same exact wheelbase length though. For example, the steering system and shaft could be shared with both FE and ME. This lends credence to your single line theory.

elegant

I like your thinking, e.g., save money by using common steering system parts. So many other cost/assembly efficiencies by using the same 106.7” wheelbase as the C7.

BTW, the Lambo Aventadore’s WB is 106.3”.

I bet in the end, the night of the reveal when we read the ME’s press release, it lists it as 106.7”

elegant

Just ran across something new to me about Zora that could remotely relate here to skank’s earlier finding about possible four wheel steering for at least an upper end ME model, e.g. ZF’s Active Kinematic Control (rear wheel steering). Since many believe the ME will be getting a ZF DCT, and ZF has a system which coordinates AKC with the DCT and with adjustable, electronically damped engine mounts, maybe?

Zora graduated from Berlin’s Charlottenburg Technical University, with a degree in mechanical engineering. One of the papers he wrote there, which was published, was on the benefits of four wheel drive and four wheel steering for racing.*

Doubt we see either of the latter two in Zora’s published paper for 2020, probably not even for 2021, but when the ultimate beast comes out...?

The front hood is hinged at the back to allow easy access to the frunk storage cavity. The battery(hopefully lithium Ion option) is at the front of car for ease of jumpstart and weight management of location. The fuel door is where it should be on the driver side for optimal ease of positioning car to gas island curbing. The one photo shows the guy holding the hood up with his right hand while his left hand is resting on the edge of the frunk cavity. Clearly a fair distance from the side of the car(Golf clubs will never fit in frunk either way). And finally the frunk will most likely have a set of optimized soft luggage fitted to the cavity shape. Soft luggage is still more flexible than stiffer Leather luggage or hard surface luggage.

The RSR Porsche WB is less than 100".
And the 488 arguably the C8 brother is 104.3".
Cornering is said to be better with a shorter WB rearward engined.

But

918 WB 107.5
New NSX WB 103.5

AWD option out there too at some point, of course!

But

Your adding weight, of course!

Height of ME is 48.5" according to our estimated calculations.

Porsche likes their street ME's longish! 106.7" sounds good.

sorry if this has been discussed already.... 17"or so HD tablet running all inside similar to Tesla... just a rumor I know, does anyone know more?
