When the current +General Motors flagship, Corvette C7 Z06 was first announced, its "creator" went through a rather lengthy process of explaining why the new Z06 would not follow in the footsteps of the previous car's design philosophy and continued with a lighter than the base Stingray fixed roof car, powered by a large displacement normally aspirated engine.
As originally conceived back in the 60's by Zora Arkus-Duntov, the Z06 designation would signify a TRACK version of the mainstream car, light and more powerful, a worthy stop gap measure before the mid engine Corvette could be introduced.
As with anything involving GM management, no mid engine Corvette happened and instead, a typical cluster fuck took place, forcing Zora to resign. Not until Dave Hill took over the Corvette program, the Z06 car was to be seen again. Dave Hill, a great guy although anti midengine Corvette (as demonstrated by his fall out with Zora later on) brought back the Z06, first as a hardtop coupe and then as a Corvette C5 Z06, followed by its C6 successor. Both of these cars fit in the original recipe for Z06, light and more powerful and perfectly capable of taking on toughest tracks (except for occasional piston slap in C5 and occasional valvetrain failure in C6 Z06).
Fast forward to +Tadge Juechter and Corvette C7. Never mind with all the problems associated with these pieces of shit and Juechter's incompetence. For some mysterious reasons, GM corporate heads and Tadge decided to resurrect the Z06 moniker and not just for a track car but what they called a flagship that happened to be the most track capable Corvette ever.
Now, in the past, the flagship was never designed to be a full time track car, thus, separate ZR1 and Z06 models, built for specific purpose, just like Dave Hill felt was appropriate. Of course he was right on the money, only a complete idiot would attempt to make a jack of all trades under pretense of creating the best ever across the board.
Apparently Tadge Juechter is such idiot since the newest Z06 is the heaviest Corvette ever, supercharged and completely incapable of accomplishing anything beyond a SHORT hero lap and occasional drag strip run.
Why no updated LS7 engine available in C7 Z06? According to Tadge Juechter, the larger displacement normally aspirated powerplant would not meet "tough emission standards" required from the modern Corvette. Tadge somehow forgot to mention which standards these would be, could he be full of shit? Could the DI and supercharged LT4 engine really have cleaner emissions and apparently comply with LEV3 emission standars and while at it, with Europe 6 standards as a "global car"? Hard to believe and justifiably so!!! As it stands, the LT4 powerplant DOES NOT QUALIFY for LEV3 certification, LEV2 only, just like the C6. Ironically enough, LS series of engines, including LS7 can pass the upcoming Tier 3/LEV3 standard with ease. Why? Perhaps Tadge could explain this part? A big hint for Tadge: higher combustion chamber temperatures do not favor lower NOx production in the exhaust stream (and neither do the catalytic converters).
To make this point clear, here is a C6 emissions sticker
And here is the 2015 emissions sticker...
Oh and there is considerably more to it... Stay tuned (pun fully intended).

ReplyDeleteI saw it, both LT1 and LT4 engines have a flawed design, with the inadequate coolant flow passages. The problem really shows on LT4 due to horsepower increase. A total disaster.
DeleteDouchebag Juetcher can't make the 427 work while Ford gets more horsepower out of its one of a kind 5.2 Voodoo flat plane V8. Hope Tadge doesn't try building a flat plane V8 since they can't build a less complicated LT1 without it fucking exploding.
