This is the C8 mid-engine Chevy Corvette

I understand what you're saying, but visualizing it makes it seem like an unnecessarily complex method that needs narrow shoes. I don't recall any YouTubes showing racers doing that but whatever works for you.

No question an auto would be quicker. I’m not debating that at all. I just find a manual and all the extra steps to be challenging and therefor more fun.

The 5 speed Mercedes transmission used for the last 25 or so years has a governor at the tail shaft that allows line pressure to pop a slider out and block the shift shaft from reverse and park.

Had a girl whose governor was stuck many years ago, you could only put the car in park after you turned it off. No money, college kid, blah blah blah. We cut the post off the shift shaft. That poor Mercedes would go to reverse at any speed you wanted

Never saw it again. So it either ended in a spectacular fashion, or is still on the road today.



It would be interesting to see a DCT apply both clutches at once. I’m sure it has happened and will happen again, not one I’ve seen though.

There is no other explanation: this is a conspiracy!

The Verus Engineering throttle pedal spacer helped IMMENSELY.
The current trend of putting the throttle pedal behind the brake pedal is not conducive to heel-toe downshifting.

I like him. Plus the video has a lot of details.

Putting your toes together is much more natural than pointing your toes to your heel.

Do a video,,, love to see it. No frickin way I'm getting two feet on the brake pedal LOL.


I will say selectable auto rev matching on downshifts in the C7 make the pedal dance easier.

I've heard similar stories and wonder if modern automatic transmissions are still vulnerable to that.

I thought most cars have a "reverse lockout" that prevents that.

I would love to know why you would need to left foot brake if doing heel and toe braking with the right foot? Maybe try right foot clutching for a real challenge.

Anything with a push button or knob can just tell you "no".

The Mercedes shifter shows a little diagram in the cluster,

R
N P
D

Depending on what you're doing and the state of the car, little arrows appear for all possible shifts.

In park, no foot on the brake, you can't do anything. Foot on the brake, they all light up. Stopped in neutral, brake on or off you can go anywhere.

It's a little tiny arrow most people probably never notice.

In park, no brake pedal.




In park, with brake pedal.




In drive, at standstill.




In drive, at speed.

You know since the 718 and 991.2, PDKs have been doing this right? They slip both clutches in higher gears to allow you to roll along with the engine at idle speed, presumably to prevent the clutch from heating up as quickly. Previously, there would only be one clutch slipping in 1st gear while you roll at 3mph, but I think it can now roll several times faster than that. The idea being it's more efficient to slip the clutch a little than to increase the revs from 700 to 1200 if you only need to maintain a slow speed. I haven't actually seen it in action, I imagine it only works up to whatever comes out to 3rd gear and 1200rpm with little throttle input.

I also believe there's gotta be some car out there using both clutches initially on a launch to reduce shock. The efficiency is still 0 when the car is stopped, but you get that extra kick of torque at the wheels with 2nd gear also transmitting torque, then you can disengage and rely on 1st gear alone once the tire is starting to slip.
