Is the Competive Driving mode equal to which? PTM in Track Sport 1, Sport 2 or Race?
What is the difference in performance between Z51 without PTM vs with?
What is the difference between Z51 without PTM when in Track mode and traction control turned off Vs Competitive mode. according to the owners manual; it appears you only achieve full engine power in Competive Mode and Race mode.
I have had 3 C7's; current is '16 Z51 non MSRC; prior; 14 C7Z51 & '15 C7 Z06 with MSRC.
Thanks,

anyone?

When I was a SpringMountain the chief instructor told us sport 2 in PTM is the same as competitive mode in a non-MRSC car.

Close in some respects, perhaps, but without MSRC the handling qualities are very different. Whether it's Weather, Economy, Tour, Sport, or Track, the suspension of a non-MSRC car is always the same.

Yep......a bit jarring. My '14 Z-51 A6 had MRSC and I really enjoyed being able to adjust the shock ride when crossing RR tracks and driving on crappy roads.

My 2017 Z-51 A8 does not have it........and wish it did. That said, it handles great all the time.

one significant benefit is u can use track mode daily!

The non-MSRC Z51 suspension certainly doesn't compare to the Track mode suspension in a MSRC model, it's similar to MSRC Sport mode.

I cannot find the 5 modes after pushing the button twice. It shows performance mode on and that's all I get.

You have to be in Track mode before pressing the button twice. I assume you're talking about PTM mode, and that your Z51 is an MSRC car.

I've put it in track mode and pushed twice. It goes into competitive mode but no wet, dry, etc choices. I do have MSRC. Z51 has MSRC right? It's on all my paperwork from the dealer. I can feel the ride change throughout the mode selection etc. How do I know for 100 percent sure tho?

Open the hood, if there is a wire coming from the top of the struts, you've MSRC.
Without opening the hood, and just looking at the back shocks, I believe the standard shock has a yellow lower section, where the MSRC is all black.

Characteristics of Non-MRC and MRC Z51's are as follows:

Shock Firmness

- Non-MRC - Non-adjustable.

- MRC - Adjustable - Progressively firmer rate in the Sport and Track modes.

Track Mode Settings

- Non-MRC - Competitive Driving Mode - Traction Control off / Stability Control on in less intrusive Competitive Mode.

- MRC - Performance Traction Management - Traction Control on and progressively less intrusive in PERF TRAC 1 thru 5 / Stability Track on and progressively less intrusive in PERF TRAC 1 thru 3 and off in PERF TRAC 4 and 5.

Of significance is the fact that among other things Traction Control moderates engine power output.

MRC is the best all-around setup for street / track use. Compared to Non-MRC, MRC provides a softer ride in the Weather, ECO and Tour Modes but a firmer ride in the Sport And Track Modes.

For track use, the advantages of MRC are less clear. Because Non-MRC Z51's have a softer suspension than MRC Z51's in the Track Mode, Non-MRC Z51's transfer weight more quickly to the rear wheels on corner exit than MRC Z51's do, and Non-MRC Z51's provide full engine power on corner exit while MRC Z51's do not. That said, a Spring Mountain Instructor told me that he turns faster lap times in Non-MRC Z51's than he does in MRC Z-51's, but that he believed that less experienced drivers would turn faster lap times in MRC Z51's.

For drag racing automatic transmission Z51's, Track Mode with Traction Control off is the preferred setting due to quicker transmission shifts and maximum engine power. Non-MRC Z51's are a better choice for drag racing, because of their quicker weight transfer to the rear on launch than MRC Z51's. While MRC Z51's could be drag raced in the softer Tour Mode, this would negate the quicker transmission shifts that the Track Mode provides.

No, MSRC is an option on the Z51, and if you do not have MSRC, you do not have PTM. What you describe above is characteristic of a car without PTM.

If there aren't wires attached to the shocks, it does not have MSRC. You can see the wires easily by looking at the back shocks, or see them in the engine compartment.

Very interesting comments, thanks for sharing.
I bought a '14 A6 without the MRSC, I thought that I was going to miss the magnetic shocks since my traded Camaro ZL1 has them stock, but that was not the case the Z51 has a great suspension which I enjoy in any type of road. No regrets whatsoever. It's such an amazing car!
