    • Mid-engine C8 Corvette leaked CAD drawing show naturally aspirated LT1 V8 powerplant

      This is very interesting considering all the talk about a new DOHC powerplant for the upcoming mid-engined Corvette. It all depends on how much faith you put in the authenticity of CAD drawing leaked onto the internet.


      A user on Corvetteforum broke down the implications:

      -Coil springs (FINALLY).
      -Magshocks (or spool valve, either way, fancy shocks).
      -Upper front arms look to be similar to C5/6/7 with trunnions.
      -Lower front arms look to be similar to C5/6/7 with camber eccentrics.
      -Rear subframe is HUGE and is a very strange mix of cast parts and welded tube. Canít tell if itís welded or bolted together in the middle.
      -Engine is an LT1.
      -Looks like factory shorty headers instead of cast manifolds.
      -Engine has alternator relocated.
      -Not sure what the upper-right accessory pulley is for. Upper left is water pump, lower right is A/C.
      -Oil filter looks easy to get to.
      -Oil cooler clearly shown above filter.
      -Half-shafts look to be the ďbolt on flangeĒ style (no draining trans to remove shafts).
      -That transaxle is BEEFY. Like, dear god. Canít tell if itís auto or manual. If I had to wager, thatís the automatic (guessing from shape of bottom of trans and what looks to be coolers hanging around it).
      -Giant flat space above transaxle is more than likely for intake box/filter.
      -No turbos shown.
      -Frame looks to be similar to C5/6/7 with giant hydroformed rails (probably still aluminum). Disappointing. I was hoping for proper unibody. Hopefully with a fixed roof itíll be stiffer.
      -Brake rotors are one-piece. Calipers are MASSIVE.
      -Side skirts are mechanically fastened just like C5/6/7. Still going to be horrendously expensive to fix if damaged.
      -Brake ducts clearly shown on front.
      A naturally aspirated LT1? Not a bad thing considering the potential of that motor.

      The other big revelation is that there may be a dual clutch transaxle. That alone would be huge.

      Take the drawings and info with a grain of salt. Nobody can verify the authenticity except GM.
