Default double clutching

I understand the bliping the throttle...but...What do you mean by double-clutching? Just pumping the clutch twice prior to shifting?

Heel-toe downshifting is this technique taken to the next level to add braking into the throttle blipped downshift. Very fun to practice and do well. Adds much enjoyment to driving! Also, with an aggressive exhaust, the engine music is INTOXICATING.
REV MATCHING is so fun! Do it all the time!

Oh yeah I try my best not to jerk but man does it feel awesome when all that torque just throws you back. Im gonna start practicing on that blipping method. Thanks for all the different inputs..you guys know your stuff.

I thought I read somewhere that the A6 has auto blip rev matching just like some of the higher end cars?

On an A6 when downshifting, at times I tend to blip the throttle in between downshift shifts, as there is a very slight hesitation. I have often wondered if this is hard on the tranny???

Double clutching is when you clutch to put the car into nuetral, and then clutch again to put the car into gear (depress clutch, shift to N, release clutch, depress clutch, shift into gear, release clutch). In my old truck driving days I used to double clutch every shift, but I've never done it in a car with a functioning clutch. Its used to syncro the gears. Why would you do it in a Vette?

From a purely non-practical standpoint, I downshift my A6 all the time when slowing down just to hear the exhaust burble!

Downshifting doesn't hurt the engine but it does wear out the clutch.

Brake pads are way cheaper than a clutch replacement. Use your brakes!

Having 4 and 5 speeds all my life I have noticed the close ratio M6 on the C6 kind of throws me off a bit on the downshifting. For example downshift to 3rd and 2nd get more revs than I'm used to. Not a problem, just a matter of getting used to it. On the M6, I really don't see a need for a downshift in any gear lower than 3rd. In 2nd you're almost stopped anyway, unless your on the track or something........

Three words... Heel and toe

The gas peddal is not an on-off switch like all the SUVidiots and automatic trans. lemmings think it is. It is a reostat of sorts.
Learn how to rev match and driving will be that much more enjoyable.

Double Clutching


This is what I do.

6-4 downshift as an example. Cruising along at roughly 65 mph - ~1500 rpm.

Put the clutch in.

Shift from 6th to Neutral.

Pull the clutch out.

REV the engine to 3000 rpm.

Push the clutch in.

Put the car in 4th.

Pull the clutch out.

Single Clutch Downshift

Same scenario as above.

Push the clutch in.

Put the car in neutral.

Rev the engine to 3000 rpm.

Put the car in 4th gear.

Pull the clutch out.

Heel-Toe Downshifting

Heel-toe is a modifier to any of the above techniques - it involves braking while doing one of the above.

While braking, rev the engine for the appropriate speed for the downshift. Use your brain to figure this out. If you have a big foot, you may get away with tapping the gas with the right side of your foot while braking with the left. If you have a small foot, you may have to actually hit the gas pedal with your heel while you apply the brakes with your toe. It's not an easy technique to learn, especially on the street.

Enjoy. Loud exhaust makes the above techniques much more fun.

I do it all the time because it's a fun way to drive and use the MZ6.

If you own a manual transmission then you can learn the fine art of Heel and Toe downshifting. For me, the C6 does not allow for true "Heeling" of the gas pedal. Rather I roll the side of the foot over to the gas pedal. Technically, there is no "toe" involved, rather the ball of the foot is hard on the brake.

The purpose of Heel and Toe is to provide additional braking via the engine's compression and to put the transmission in to a more useful gear to exit the corner during racing conditions. It has no other purpose in day to day driving other than to reinforce your Heel and Toe skill set. It does cause additional wear on the transmission and clutch; how much depends on your skill set and gear choices.

Use your brakes if you never going to race or travel the high speed curvies like the Tail of the Dragon. However, if you just want that wonderful "Wambaa, Wambaa" sound like Sterling Moss or Phil Hill produced diving deep in to a curve(or offramp ) then Heel and Toe shifting is what you need to learn.
