If starting from stationary on a flat in maual mode would you ignore first gear

Are you wanting to do a fast launch or just normal driving?

Depends on conditions normally. If it's wet I'll normally set off in 2nd.

A quick start

It would depend which engine and gearbox you have whether its even worth considering, but for faster go, they stuck that first gear in there for a reason.

The only time I would really recommend skipping first gear is in a truck; some have a very low first ratio to help when heavily loaded and starting off up hill, so its often worth skipping straight to second as when unloaded or flat you'll only be moving out of 1st in about half a second.

In most cars, the gearbox is designed to use all the gears. The only times I skip any or block change (mines manual, I think its possible on new-ish autos too) is when I need instant power (block down) or I've accelerated too quick and conditions change so its not worth holding it low any more (block up).

Skipping first only increases the torque pressure on the box (which wont do it any favours), and generally wont save any time - the shift time is so short you'll almost certainly loose more in the decreased acceleration from rest by starting in second.

2nd for me all the time, even for a quick get away. I find 1st too low most of the time and you have to change up immediately. In 2nd you also have less traction issues.

I find that when you 1st pull away ie from the drive etc. the auto starts off in 1st but after you've moved from a standstill it usually pulls away in 2nd after that. Well mine does lol

I've taken first up to max revs and it's around 30mph so not that low.

I'm sure Marco will come up with a max in each gear table

Not tried Launch control yet but surely that's the indicator for best acceleration.

Yeah, then too

(but not exactly aiming for a fast gettaway, just getting away).

This is thrust/ton, the definition of acceleration, v's speed graph. Auto in blue & manual in orange. I've cut off the post-change point acceleration because it makes it very hard too see at the change points.

Which is faster? Well, the auto enjoys a 13% thrust advantage to 60mph but from there it's close as makes no difference. However that advantage can be completely swamped by a near-perfect manual launch.

On the open road if you're wanting to press on in a relaxed road drive then 4th & 5th are hard to argue with in the auto, but for harder more technical driving the manual's second gear it's a work of art!

2nd gear in manual is epic. And third is pretty Savage too

My quickest standing starts come from 2nd gear launch
