Default High (damaging) RPM At Start Up

Now that I've owned my F Type for one week, I have noticed that the engine revs fairly high at start up.

As much as I enjoy the sound of the tuned exhaust, I have two problems with this design feature.

(1) There are situations when I would prefer a less dramatic start up. Said another way, sometimes I just don't want the attention.

(2) When a vehicle has been sitting for a period of time, the oil drains back to the pan. At start up oil takes a few seconds to properly circulate and lubricate. Higher RPM at start up can cause premature wear from the momentary lack of proper lubrication.

Just my thoughts...

I think this has been discussed and the consensus was 'thats the way it is' - the behavior cannot be changed. 'Theatre' they call it.

Even though the tach rotates to max on start-up (that's for show only), the engine is only revving to about 2500 rpm.

And the second act is even better!

Well, my neighbors know when I come home at 4 AM after closing down the clubs, and I know when he goes to work in the morning at 6 AM with his super loud Mustang.


We're both car guys, and it's no problem.

Having issues with the exhaust is like moving next to the airport, then complaining about the airplanes.

well, not entirely fair. The car comes w/ a dynamic mode/exhaust button because we want both the ability to cruise quietly around or have fun. Just wished this dual mode option existed for startup because in some situations it is rather noisy

It, whether in V8 or V6, is what it is, isn't it?

I think the factory was trying to replicate a vintage high performance feel with this. Add this to the cramped interior, poor sight lines, lack of storage, etc. Not sure it all works for me but on the whole, the car does feel special.

Guys, this has been a trick on a lot of non-US manufactured performance cars since the 90's. Heck, my old 1993 Mazda RX7 had it as well (called AWS, Accelerated Warmup System). An early rev and little higher RPM for a few seconds help warm up the catalytic converters to aid with emissions testing.

In my opinion it's more like a treat than a trick!

To stop it from revving like that on start up, with your foot OFF the brake, hit the start button. It should be like turning on only the accessories. Then put foot on brake and hit the start button like you normally do to start the car.

That makes no difference. This technique was discussed here months ago and debunked.

Agreed. There is no way to stop it. Just stop resisting, give yourself over to it and start enjoying the experience.

It seems to work sometimes for me, but not consistently.

I seem to recall one occasion where I experienced that when playing with the car shortly after delivery. I rarely do this, but I think if you re-start the car within a few minutes after shutting it down, that sometimes happens. I don't think it has anything to do with hitting the start button first with your foot off the brake.

When that theory was advanced here some time back, I tried it numerous times on a cold start, and it never made a difference.
