2014 Chevrolet Corvette: Rev-Matched Downshifts

November 20, 2013

2014 Chevrolet Corvette

Among the long list of tech features in our long-term 2014 Chevrolet Corvette is rev-matched downshifting. Basically, when you activate the system, the throttle is automatically blipped during downshifts. The idea is smooth, no-lurch, perfectly rev-matched downshifts. Great for when you want to make fast time on a good road, and especially useful to avoid upsetting the chassis in braking zones on a track.

It's a technique first seen on the Nissan 370Z as SynchroRev Match. In that car, the system worked flawlessly. Lightning-fast rev matching. It's brilliant.

In the C7, the rev-matching feature is not quite as effective. The system is slower to bring the revs up than Nissan's system, so often you find the revs not really matched by the time you engage the clutch for the next gear. Lurch.

What I find is that in order for the C7's rev-matching system to work seamlessly, I have to slow down my gear changes. This makes the system workable for when you want to be lazy, like around town, but ill-suited for fast driving. Irony.

    That's disappointing to read. Hopefully something a simple software update can address down the road.

    Fail. Like all of GM. Didn't we kill this company already?

  • At least its a "free" feature that comes standard on all manual Corvettes. Still, its disappointing that Nissan set the standard with the 370z and GM failed to produce an equally effective system. Hopefully the system can be improved in the future with a software flash, as stated by 330i_zhp.

    Any chance the laggy behaviour is due to emissions controls?

  • More importantly, are the pedals properly placed for heel toe shifting?

    How hard is it to get used to trusting the system? I think for a while I would still instinctively blip the throttle myself on downshifts, just out of habit. Just thinking about downshifting without a rev match just seems weird to me.

    Irony, yes. Don't need to for leisurely driving. Maybe they have a software update that can fix that

    The rev-matching feature is better suited for amateurs to manuals driving the car casually, or for traffic. If you wanna drive fast or track the car and think of yourself as a pro, you either man up and learn to heel-toe, or you get the automatic. End of story. The C7 destroyed the performance car market. The Z06 will s**t all over it, and the ZR1 will flush it down the toilet. Stop blasting the car for the tiniest of details, like your stupid '10 things to modify list'.

    I think its an engine design trait. My experience has been that GM small blocks don't rev as freely as OHC motors. There simply isn't enough time to rev up from when the shifter indicates which gear you want. It could also be bc a V6 has less cylinders to rev up.

    "Stop blasting the car for the tiniest of details". Then why are you reading long term evaluations of vehicles, isn't that the point of these tests? Are you saying that a potential owner looking to drop $60K on a car doesn't have the right to know of, or observe the tiniest of details?

    @ duck87 'Are you saying that a potential owner looking to drop $60K on a car doesn't have the right to know of, or observe the tiniest of details?' Because things such as the Corvette having 4 exhausts is too much, or that the engine Start button is

  • goaterguy goaterguy Posts:

    If you set the car to Track Mode, will it still take the same amount of time to rev-match or will it be faster?

  • mfennell mfennell Posts:

    So, can we assume you CAN make downshifts as fast as you like by heel-toeing the old fashioned way?

  • duck87 duck87 Posts:

    @vlad_x35: I'm glad that you're the ultimate, go-to authority on what Corvette owners should and should not know.

  • Sorry vlad but Nissan apparently nailed this system with the 370Z so why couldn't Chevy? Seems like more than just a tiny detail to me. Just because the car is amazing doesn't mean we shouldn't expect features to work properly.
