I'm about to order my 2016 F-Type S MT and was SO SADDENED to read in a thread that the decel pops & cracks of the AT were absent in the MT. Someone commented that they may come back after break-in? Anyone out there with a 6-Speed MT that can comment? I've been waiting to order my MT and now I'm having doubts since I love the sounds of the MT - I thought they'd be enhanced on the MT. What's the reality of the situation?

 

I would love to rid myself of the embarassing pops and crackles- they serve no function accept to draw attention to your car in a negative way. Spitting unused fuel into the headers for noise is window dressing. Even sport exhaust unless it opens up the airflow is just window dressing

 

With a sample size of only one to date, we can't be certain that it is the norm, but I find the crackle and pop to be not nearly as much as on the AT. In fact the V6 MT sound is quite resonant and melodious, very reminiscent of the larger displacement Ferrari V6 engines. If any of my race cars of yore had sounded as ratty as the AT version, we would have been trying to get the ignition sorted out or would be suspecting that the cam chain had jumped. I'll occasionally get a series of 3 or 4 pops on a vigourous downshift, but they are throaty and measured, rather than raspy like the AT. To date, most folks have been making reference to the glorious noise of the F-Type. The MT produces, not noise, but a glorious (and voluminous) sound. Pick your preference and choose your car. For me the MT version is as perfect as one can expect.

 

What type of shifting are you doing with the manual? The pops are largely a function of throttle/rpm...you can definitely drive the auto around without pops...just keep the revs down. the car has a lot of torque, you can drive it normally with low revs and no pops.

 

Good point. I'm certainly trying to keep the revs under 5k and not applying full throttle during break-in, but really didn't notice too much difference when I "accidentally" exceeded those parameters. It's definitely less raucous than the AT but just as loud when driven under the same conditions.

I always double clutch a downshift at the upper end of the rev range. I'll use the synchros and see if that causes a difference in the popping.

And to amplify, most of the popping and crackling on the AT is a function of running it up to relatively high revs in manual mode, and then releasing the throttle to decelerate. It's also very pronounced when driving in sport or dynamic mode when manually downshifting to decelerate.

It happens to be one of my favorite things about the car, but it's entirely possible to drive it "tamely" (in regular and automatic mode) and not hear the "fireworks" at all. JLR has purposely programmed the ECU to inject a little extra fuel when the AT signals deceleration at a certain rpm, some of which is unburned in the cylinders, but ignites in the hot exhaust system. It's a nice little touch that virtually every car reviewer who has driven the car, as well as most owners express delight over.

Many months ago when the reviewers first got their hands on the MT, at least one reviewer expressed disappointment that the MT version did not make the same pleasing sounds. At that time, we had a brief discussion here, and I mentioned it didn't surprise me because I don't see how the MT could communicate with the ECU in the same way as the electronically controlled AT.

Lhoboy has confirmed the difference since taking delivery of his car, and he's the only owner we've heard from yet with an MT.

 

In about 5 weeks I should be through the break-in period and will see if decelerating from redline produces the crackling/popping effect.

 

You should check out this video posted by a new owner of the base F-Type -- at the 1 min mark you'll hear the snap crackle pop ...

I uploaded another video. The crackles and pops still happen in 1st, 2nd, 3rd and sometimes 4th in dynamic mode and active exhaust on.

lhoboy - the pops & crackles in the MT video posted above sound pretty good to me. Does yours sound similar?

 

After 800 miles, mine has started to pop and backfire pretty good on decel. Crackle, not so much. but that might be because I'm in the Coupe (windows always open though). I'm not a fan of cacaphonous crackles anyway, so I'm REAL happy with the harmonious sound that mine has. Throttle blipping and double clutching adds a whole new dimension to the sound these cars can make that the ATs are missing out on.

 

502 miles and mine sounds like a bowl of Rice Krispies on crack on the overrun.

 

Must be the difference in cabin sound between the coupe and ragtop. (or I could be deaf in that frequency range)

 

The coupe really muffles the sound from inside the cabin. I had my girlfriend drive he car while I was outside. It's really toned down when sitting in the car vs hearing what other drivers hear

 

That is true in the V6 or the V8, MT or Auto. The ONLY time my 17 year old son got to drive the R was when I wanted to hear it from the outside and I had him drive around the block.

Damn, was I worried...

It's actually pretty quiet in the Coupe compared to standing outside and listening to all the "warfare" sounds.

 

The convertible is loud all the time, top up or down, and I love that. I also perceived the coupe to be much quieter during my test drives. Surprisingly though, there's very little wind noise with the top up.

 

Ok - I must say I was concerned about the possible lack of cacophony in the MT convertible, but now I'm nothing but excited. The sound was a major factor in my buying decision - I better check at the dealer to see if my radio works because it will get very little use for a while. Now, any tips on how to make the next 4 months pass more quickly??

Well over a year into my ownership of this car. I still find myself turning the sound system off most of the time so that it doesn't interfere with the lovely engine noises. That's the major thing I enjoy about it.

 

Yes, that's easy. Think of me putting my deposit down at the Goodwood Festival of Speed in 2012 and then making monthly calls back to Jaguar UK asking if they had found a place to put a third pedal yet? Four months is easy compared to three years of living in purgatory.

 

The AT cars do throttle blip - pretty aggressively - themselves.
