Yea he trashed it and warranties cover that !!
No, he didn't "trash" it. A connecting-rod bearing failed and chewed up the engine internally.
Nice try on the guess though.

No modeling. No failures. And maybe 10% over use of materials.
If you think you can build a cocktail napkin chassis within 10% of the weight with equal stiffness that a halo car engineering staff can by using off the shelf tubing and frame gussets you are deluded.
If you were to examine your chassis with FEA you would likely find lots of weak and overbuilt parts. Chevy will be grasping at grams in the building of this car, not to the extent of a Euro hypercar but a few ounces here and a few ounces there even if it is sprung weight will keep them up at night. They will also be much more worried about COG than you are, moving heavy stressed members lower and inboard will also be a major emphasis, all while having to meet passenger car regulations.
The engineering teams on halo cars are some of the most practical you will find, the same is true with high-level racing.

Oddly reminds me of the late WWII era Grumman Bearcat referred to as "an engine with a saddle."

Said one 1950s Navy pilot, “The Hellcat was a Buick, the Corsair a Cadillac, but the Bearcat was a Maserati.” Another likened it to a Harley-Davidson, a classic celebration of Yankee excess. And to revert to an even earlier transportation era, a third tailhooker called the Bearcat “an engine with a saddle.” He wasn’t kidding. The Pratt & Whitney R-2800 engine weighed about 3,000 pounds, and the airframe behind it totaled 4,000 empty. To say a Bearcat was half engine isn’t much of an exaggeration. “Pretty hard to strap a bigger engine on a smaller airframe,” Deakin points out.

The Grumman F8F Bearcat is the Dodge Viper of airplanes. Both are outrageous, lightweight, in-your-face- American, monster-motor artifacts of fast-disappearing eras, designed on the cheap and produced quickly. The car/airplane comparison even extends to the fact that both have what might be considered truck engines: the Viper a V-10 originally intended for big Dodge pickups, the Bearcat an 18-cylinder, 2,250-hp radial (in the F8F-2) that some fighter purists would consider a “bomber engine.”

Cadillac was going to make a mid-engine sports car before Corvette stole the idea.

Zora Arkus-Duntov's last words to Dave McLellan when he left Chevy in 1975 were Dave you must build the mid-engine Corvette. Chevy has continued to entertain the idea since the CERV I and CERV II. The seed finally germinated, if they meet their price targets it may indeed blossom.

With Cadillac going electric it will be fun to watch.

It looks more like a Euro Supercar than a Corvette.
