Hi Guys,
Can anyone explain to me how launch control works. BMW ///M sports cars have launch control, BMW ///M8 is a good example.

Does anyone know why launch control was never implemented for the V8 version of the Jaguar F-Type sports car.
Thank you.....

 

The ‘dynamic launch’ on the V6S is pretty rudimentary, it just keeps engine torque up through shifts.

As Dave mentioned, launch control is only available on the V6-S. The V8 has too much torque and the higher rev up could cause damage.

Yes, you are correct for the V6 model
But ..... if the BMW ///M8 has launch control why couldn't the V8 engine F Type sports car have it. The M8 has a 4.4 little engine with turbo. How did BMW figure it out.

 

Bad and unrealistic answer if that's Jaguar's position. Audi is able to install launch control on the RS6 using essentially the same ZF 8-speed box with 621 HP, 627 lb-ft of torque in a car that weighs just shy of 5,000 pounds. Launches at about 2,500 RPMs. When I had my RS6, I used it on numerous occasions with a stage 2 tune without issue.

 

I was recently flirting with the idea of buying a F Pace SVR (to replace the Mustang which was getting very tiresome when I had to drive it 3 weeks straight) and the review here showed launch control

 

Does anyone actually use launch control past a week after they bring their car home?

 

funny you say that, I was so disappointed I didnt have configurable dynamics in the F type so made sure we got it in the XE, I've played with it once in 5 years which is one time less than I played with the configurable instrument clusters

 

Yeah, weird that the RWD V8 cars didn't get the launch control. The gearbox shouldn't be an issue. But as said you're not missing much if you don't have it. I've just tried it a couple of times in my car.

Still I played more times with it than with the other most pointless options - the configurable dynamic mode (why would you want to dial down the throttle response, shifts, steering or suspension in dynamic mode?), configurable mood lighting (the default ice blue looks best by far anyway) and the parallel park assist (I tried hard once to actually use it, didn't get it to work, just useless).

 

The F-Type has Dynamic Launch, its in the manual. I hadn't tried it myself yet as I'm a safe driver

 

I actually like and use this feature because I think for most street driving the standard suspension setup is a good balance between handling and comfort. So I have mine set up where everything is set to Dynamic except the suspension. If I'm going to track it, I'll switch that as well.

 

They never removed it from the owner's manual but only the V6S ever had it. Your '24 does not have it.

 

My default is standard on the throttle, dynamic on steering and suspension. The throttle setting changes where the pedal is more sensitive, and I like it a little less sensitive in the first quarter of travel. I also don't like it when I switch modes while moving and the throttle changes. As for launch control, the 6MT has always had it

 

Launching a car you want to keep just seems too harsh and per my mechanics over the years not such a good thing to do even if there is a launch control. Been following that advice and have not to date had a diff issue.

The cool thing to me is 30 to 70....these cars are amazing...especially if stage III in a V6 from VAP with TCU tuning.....shockingly fast.

Saw TopGear do this once in a 996tt and was hooked.

 

I avoid hard launches too. If 0-60 is that important, get an EV. For me, there's far more joy to be had on a country road in the fat part of 3rd gear (on the 6MT).

 

I wish I could have traction 30-70 (stage III V8 on RWD)

 

Oddly enough once I went to forged rims and Michelin tyres, the ride in my car on 21's in dynamic is as good or better than it was on OEM 19's and P zeros. So in mine I'm happy with the ride in dynamic on everything except really bad roads where it gets a bit jiggly, not that I put it in dynamic much.

 

I'm taking this a bit further off topic (sorry OP) but I've noticed things like this before. It is possible you reduced your unsprung weight by a decent amount, and that works better for your dampers. Their job is to stabilize movement while also giving in enough to the road surface to maintain traction and ride quality (a moving target based on your goals). A suspension works as a system and is affected by tire/suspension mass, spring rates, damper rebound/compression, along with a bunch of other things like alignment, camber curve, sidewall stiffness, etc. Example: with stock springs on my 2015 R, comfort mode was exactly that, and dynamic was a bit overdamped. Now they I am on H&R springs, they are stiffer and damping in dynamic fits them better - and it actually rides better than comfort, and not much worse than stock in dynamic. Why? Not exactly sure yet but my theory is it is running out of suspension travel - either just limited to begin with, or maybe rebound jacking down, probably the former - it could be hitting bump stops early due to limited travel. Just a theory though.

 

Cheers, yes the rims are a lot lighter than the OEM wheels (Jag build them to cope with very bad roads, even the OEM forged are heavy) and when I checked the tires are also lighter even though they are wider, maybe due to less sidewall. The positives are (in my case) a better ride, better handling, and with the width of the tyres less risk of going into a pothole. But I have noticed that if I am powering around a corner and there is a bit of rough road the car can skitter a touch, which I put down to less weight keeping the tyre in contact with the road, so maybe bouncing up a little more than stock.

 

Agreed, hard launches feel pretty pointless and arguably plain stupid if you have a sense of mechanical sympathy. WOT while the car is up to speed is another topic though.

Interesting to hear some other views on on the configurable dynamic mode. I really like the sharpened throttle response and different gearbox behavior in dynamic mode but always thought that the steering and suspension differences were way too small and barely noticeable. But then I live in a part of the world where the ride is not an issue because most roads are perfectly smooth and potholes are pretty much non-existant.

It would be nice if there were some more levels to choose between and not only comfort or dynamic. I know that the suspension can get much harder than in dynamic mode. A couple of years ago I got a random suspension error a couple of times, maybe because of a low battery, where the dynamic suspension was disabled and you could feel a big difference in stiffness even on smooth roads.
