Hmmm... so it seems perhaps manual 0-60 times are even more artificial than the auto ones. In fact if anything auto could be regarded a much more accurate and replicable 0-60 because there's only one way to do launch control and only one way to change gear i.e. do LC and then keep your foot on gas. Interesting...
Now you're getting it. smile

A manual might feel like it's taking less time, but that's because you've got more to do. If you're busy shifting gears, using the clutch, etc. then your mind is busy, you're doing things quickly, and so you think it's faster - it may not be.

Same example with "advanced driving" - with proper observation and anticipation you don't feel you're moving quickly because you're not rushed and are driving smoothly. The speedo may tell a different story. wink

But your own foot can do that too by not pressing so hard hehe
Are you deliberately being a 'tard? This is how launch control works on all cars tongue out
No im not. In an auto it makes sense. In a manual where you have to do the clutch control etc all yourself, what is it doing other than stopping the revs at a certain point?

Launch control in an auto is supposed to load up the engine ready to go as quickly as possible. How can that happen if you have your foot down on the clutch? It also is supposed to shift as fast as possible but you can also mess that up yourself in a manual.

Minimal wheel spin aided by a slightly different torque model designed for hard launches rather than designed for reining in errant driving. Yes you can still mess your shifts, but that is not what launch control is actually about. See this for an example of a manual using launch control (the auto version does not come with launch control btw)

The auto times will be with LC.

But the manual book times will often be scored using a brutal method that you'd not want to do anyway.

So the comparison is moot. Just buy the one you like driving the most.

Ok... So.... Thanks to great replies my understanding is this:

0-60 times are with LC whether an easy LC I would never use on an auto or a brutal LC I'd also never do on a manual.

So that brings me back to my original point and I'm thinking pulling off at traffic lights here: As I wouldn't be using LC for either (without being dangerous and look like a bell end) is the manual likely to give me a quicker jump off the line because at least I'll be able to use a "partial" LC. Eg rev up to 2-3000 or so without sounding a tit and without spinning and then dumping the clutch when the lights go green so I at least get a bit of a boost? Because auto it's binary. Either use LC or just go from minimal revs. I think that's the essence of my questioning here.

It's been so long I've had a manual i just cant remember! I also can't remember how quickly you would change gear to second pulling off at the lights (because my DSG just does it without me thinking - it really dumbs you down!). Because if you go up to second very quickly (IE 2 or 3 car lengths) then the DSG would have the advantage of much quicker gear changes to throw into the mix right?

Why are you in such a rush to pull away from the lights?

Or rather than worry about spinning tyres and geachanges slip the clutch off the line in second (if the cars got enough grunt), no tyre squealing and one less gear change to worry about. First gear on most cars is very short anyway..

0-60 times will give you an indication of a cars performance but as I've learnt over the last few years......

I the real world, it's irrelevant.


Until you're comparing dick sizes in the pub.
This comment just reminds me of the Saxo VTS with it's pain in the ass of a 2nd gear that they made artificially long so when you take it straight to red line it will reach 60 before 3rd, allowing it boast considerably faster 0-62 than competitors. In the real world when your not flat out it meant that even slightly short shifting 1st gear caused the little 1.6 to bog down.

Because there is no law limiting how fast you can get upto 60? whistle
