There is a similar question last winter when some wasn't sure why their brand new EV couldn't deliver the stated 0-60 time, if I remember it was around November with temperatures in single digits and plenty of wetness around.....

How do they know the cars can’t deliver the quoted 0-60?

What on earth is this about? The question and the associated explanation, are barely intelligible.

Unlike the OP who's usually measured in his cross platform posts.

Perhaps he could clarify the point of the thread.

I don't know why we're addressing a muppets post on another platform on this one... but whatever...

On the point about EV's on wet/cold roads:

The thing being experienced is an EV's very responsive traction control. Most EV's, in most drive modes, will detect fractional levels of wheelslip and instantaneously (or very close to it) reduce torque to match the level of grip - and then repeat that calculation and adjustment every few milliseconds. The end result is near imperceptible TC that maintains the cars rate of acceleration on the very limit of what the conditions allow.

Because there's no initial wheelspin detectable to the driver, some people think their car is acting overly safe or is broken in some way. But actually, the car is providing the fastest possible acceleration each time - it's just doing so in an undramatic fashion.

EV's are great at launching, but they still have to do the job within the limit of physics smile

Never had an issue in cold weather. It's just like any powerful car. Treat with respect, don't be a tool, all is good.

Mine's also no slower. And it's nice to not have to wait 30mins before everything is warmed up in the engine/gearbox as you should with ICE.

This in buckets.

Doesn't matter if it's snow/ice, or a puddle... the lack of drama is impressive. Your accel slows as you hit the problem... and then ramps up again when you leave, and the only sign is your perception of accel change.

The Tesla forum thread believes this is "Obstacle-aware acceleration" which prevents acceleration when the car think you're going to hit something

Yup, it's that. Pretty simple - you turn it off.

I've never suffered this, so left it on. Some people seem to though, a bit like phantom braking.

I would have said this as well. It will effectively hold the car back if it thinks you are going to launch into something.

That's interesting - my BMW does something similar too actually, sort of gives a the briefest of pauses as if to say "you sure about this?".

Funny how you get used to such interventions! I hadn't even considered the Tesla might do the same.

It's a delay while your car phones up Musk and asks how much power he'd like you to have.

My Nissan Ariya does this occasionally if it thinks theres something in the way or you're about to crash or drive into something etc.

100%.

When you have a small gap and want to "throw" the car behind the one that just past, it might stop you doing that for half a second. Only had it happen pulling out of a cross road, when you push the pedal from standstill and there's a car still straight in front of you.
Never found it dangerous, but it is noticeable.
Didn't know you could turn it off, but it never really bothered me tbh.

Definitely Tesla’s obstacle-aware acceleration causing this. It’s the only piece of the Tesla tech that I turn off as I’m not an old lady in danger of driving through the front of the hairdressers after pressing the wrong pedal.
