    Nothing too surprising there, but an interesting read nonetheless. They really should’ve tested a manual with a 3.73 gears though, just to eliminate another difference.

    I still prefer to drive a manual, though I understand that I’m now in the shrinking minority.

    Multiplying the torque for sure. Once the revs reach peak the auto keeps it in the powerband very efficiently.

    Not surprising.

    What I didn't see mentioned was that Ford gutted the ratios for the 18 manual as well. It would've been closer with the 15-17 MT82, albeit still a loss. The shorter ratios combined with a higher redline is powerful, but for some reason they stripped it away.

    The 18 mt-82 are breaking shift forks because ford decided to go cheap with aluminum shift forks. Don't they know that aluminium in that application is weaker then steel?

    Seems off a little to me. I don't doubt 1/2 sec quicker in the 1320, but not sure I'm buying a full sec behind at 100 mph and making up 1/2 sec in that last 400-500 ft. I still think with a tune and tires, the M6 can be in the 11's. Hopefully, we'll soon find out.

    I thought the manual did have 3.73's...according to the tech info anyway? Right?

    Technology will always get better. Man has already hit his limit of performance. If you wanna go fast and be consistant. Get the Automatic. If you don't care about a couple 10ths. Get what you want. Side note. Heck of a trap speed for a hot day. 119 is amazing.

    I have no insight as to the validity of the post but it is being spread. My son and his friends who are not on here told me the same thing. So it’s being spread regardless if true or not.

    Again, I have no first hand knowledge one way or the other.

    Great article, one I think many of us were looking for. It wouldn't stop me from buying the manual, but it's great to see a perfect match-up of auto vs. manual.

    Two things struck me from the stats;

    1. Weight. These are damned heavy cars.
    2. Dat lateral G tho!!!!! 1g for the manual!!! I think that's largely down to the new MP4S tires. Gonna' put them on my car next. Don't know why though, I've never taken my car past .72G in a corner.

    I suck.....

    I do believe motortrend applies correction factors to their 1/4 mile times.

    I noted the difference in the lateral G as well. It doesn't state they both are PP cars but judging by the stats I'm guessing they are...

    They do. Im pretty sure they correct to see level. Where I race we see DA of -2000. So compared a 119 trap to the 2017s 114 trap. Pretty anazing.

    Gotta be. I'd guess a standard GT wouldn't get much past .85 or so. Plus the weight being so similar.

    I can't imagine having the power, without the control. Gotta do at least PP1 on these cars.

    Manual PP1 is the way to go with the GT. Would gladly be slower than the auto as long it’s a manual.

    The 0.9 second difference to 100 isn't that hard to imagine, given that the acceleration plot shows three upshifts taking about 0.3 second each. By comparison, there's barely a wiggle on the AT's acceleration curve.

    Incidentally, on every MT upshift there's going to be a brief deceleration that probably doesn't get compensated for by sidestepping the clutch pedal in the hopes of getting a brief spike in acceleration on the finish of each shift. My guess - the MT is losing half a mph or so on every shift that has to be done over again in the next gear. A bigger mph drop at higher speeds where the greater aerodynamic resistance slows the car more in any given amount of time.

    What MT is not showing is the distance it takes each of these cars to reach 100 mph. The MT car is going to be taking more distance to get to 100 (because its acceleration is consistently a little less), so once passing 100 mph it doesn't have as much further to go to the finish line as the AT car does. And a couple mph trap speed difference in the AT car's favor isn't going to change that around to the AT taking less time to go from wherever it hits 100 mph to the end of the quarter mile. It's hard to see this when all you have is the numbers because what you're trying to do amounts to performing integral calculus in your head.

    If both cars had the PP, the stick car should have been rocking a 3.73 rear.

    It keeps the rpm in the power band so much better being 10 speed.
    More power more speed.
