  • ME Advantages & Disadvantages

    What do you think will be the inherent advantages of a ME?

    What do you think will be inherent disadvantages of a ME?

    As in all things in life, certainly for all sports cars, there are always trade offs. Starting with a few...

    ME Advantages:

    *Lower center of gravity due to no driveline running the full length of the car;
    * Better traction off the line and coming out of a curve due to engine weight being over the drive wheels;
    * Better corner “turn in” due to less weight on the front wheels (less plowing effect);
    * Better braking efficiency;
    * GM will have incorporated six years of additional “automotive learning” in such areas as light-weighting, component evolution, powertrain advancements, aero progression, advanced safety systems, etc.


    ME Disadvantages:

    *Less cargo space;
    *Greater cost to manufacture;
    * Harder to keep the motor cool;
    * Overall repair cost IMO is going to be more;
    * For those persons who like to do most of the repairs themselves, some will be more difficult;

    In summary, as postulated by a smart person, with his referring to what we have seen from CAD drawings, and based on his evaluating not only the above factor but also others, here is what Quinten concluded. Thank you Quinten for this concise, quality, and well-thought-out summary!

    [Quote=Quinten]The Mid-engine Vette, by design, will have less mass, a lower and rearward center of mass. Better aerodynamic efficiency, and more traction. GM’s chassis engineering is world class, especially with the C7 and Alpha platform. We’ve seen how good the new (ME)suspension setup is, and there’s no leaf spring. The powertrains are going to be brand new and much more efficient at producing power. Wheel horsepower should improve due to the lack of a Long drivetrain. The mid-engine Vettes will have downforce producing, lift reducing features built into the body versus the C7 with mostly tacked on pieces.[/Quinten]


    Your thoughts?

    I was just reading an article about Zora, and as he noted, a ME will have better braking efficiency (so I added that into the above post).

      Pros: It'll have a lower polar moment of inertia, which can (but doesn't necessarily guarantee) improved turn-in and handling on track. It will certainly feel lighter on its feet, due to the decreased weight over the nose and the lower polar moment. Will put power to the ground better from a standstill with superior weight and weight transfer to the driven wheels. Will be able to feather throttle-on sooner at apex. Should have better cd/drag. Shouldn't tramline as much on road surfaces due to narrower front tires. Braking is more efficient. For folks that street drive and don't track ME will allow much higher power levels to be accessible due to better launch capability.

      Cons: Guys used to driving FE on track will need to adjust driving styles. For on many tracks/turns, where you might trail brake into the turn in a Z, such will often switch ends of a Porsche or ME doing that. Also, the penalty for harshly lifting on turn entry will be more severe, especially in off camber corners (where you shouldn't do it anyway). Fairly easy to adjust to - just a different drive style. An ME can push in turns depending on aero and grip/set-up. Thermal management will be very important, but if nailed, will be a pro, not a con.

        Excellent post OnPoint. You did a great job in clarifying, amplifying and helping many of us learn more.

        Kudos!

          Pros; Considerably improved forward (including apex identification) visibility. Perception of less mass in routine maneuvers.(ME cars just “feel” smaller) More “exotic” presentation. (Subjective).Potential for adjustability of heightapproach angles.
          Cons; Learning curve for creative storage (available storage space still speculative) Rearward vision compromises (speculative) Engine sounds coming from the rear may be an adjustment some may have to deal with. I personally find it a “pro” vs “con”.

            I am loving what I am learning from very precise posts above. Thank you!

              After 20 minutes or so driving my C6 I'm feeling a fair amount of heat coming through the firewall and tunnel. Hopefully this won't happen in the ME.

                Yes, it was a factor with the C6. Not so with the C7. ME a totally different proposition.

                I’ve had several mid engine cars and totally agree with Foreverfuely and OnPoint. ☝?
