I'd actually like to see performance when not using sport boost, launch mode.

What happens when you just punch it?

What happens in a standard 60-120 run?

You know, just driving normally like the hooligan I am.

I know I know im being picky
I know what you're saying. If this was the size of a 5, at the same weight it is now, with about another 100 hp, I'd be all over it for $20k more or so.

As it stands, it's in a weird spot. The M3P is probably more fun to drive, while this is is heavier than a Model S LR without the power.

I'm not sure it allows you to use LC without sport boost, but maybe I'm not correct on that.

I've seen videos of a guy testing 0-100 kph using different modes

Eco Pro was around 5.0 (tells me it's always RWD, but this is an assumption based on the i4 edrive40 on dragy has done it around 5.1 seconds on a cold surface day)
Comfort was around 4.0
Sport was slightly quicker
Sport Boost, LC was around 3.5

Yes, that is the video. I love how the car literally did 0-100kph in about 3.5 seconds (+/- .2 seconds) at 39% SoC in that video

Battery state of charge be damned!

Also, the first acceleration run was 88% at 386km of range. Given when it was posted back in Dec and it was in northern Europe, that seems to be a decent range to boot.

Throwing this out here. I really think in Eco-Pro given the 0-60 time is similar to an i4 edrive40 on Dragy, that the Eco-Pro IS mainly RWD but has the front motors help during launch to eliminiate wheelspin and then they back off those motors when it's not needed.

Regardless of selected mode (unless it’s the sport mode), the car is RWD. But it quickly enables AWD whenever needed. That’s my understanding from the press release

Some more data points for 0-62mph.

Sport boost + LC 3.94
Sport boost 3.94
Comfort 4.08
Eco 4.30

Looks like BMW have replicated typical BMW axle tramp to perfection to give that ICE feel.

To be fair, damped roads + TCS/DCS off.

I like that BMW gives you full disability of those nannies with a touch of a button.

I figured there would be some difference in each mode minus LC which looks like should be reserve to dry/higher traction surfaces. Eco-Pro doesnt appear to be too much of a snail and seems perfectly adequate for 95% of the time for me.

On a side note, is it ever dry in Europe in winter?

55% SOC and wet pavement. Do you actually think those conditions make these meaningful numbers??

Absolutely, yes. It is what you would expect in real world conditions.

It's an AWD which makes the difference between damp and dry, very small, maybe a couple of tenths.

Wheel-spin is often seen as slower and undesirable, not necessarily true. Most performance engineers agree that some wheel-slip is optimal to get highest traction and allows for the drive system to gain inertia.

No idea about SOC affect on power. I would hope that full power is still available at levels down to 30% at least.

30% SOC full power? LOL. The Tesla loses 64hp at 45% SOC.

https://insideevs.com/news/381551/vi...ance-soc-dyno/

Furthermore, in the i4 making more HP and almost 600lbs of torque, wet traction will be more of a factor. Beyond me how people testing these cars would test at a low SOC. Car Wow did the exact same thing, and yet the BMW still pulled on the M3P.

Wheel spin vs no wheel spin is never good if your cutting power output compared to a dry surface with less throttle intervention, lol.

agreed 100%.

Excessive wheelspin is never good even on an AWD car, and this is what 5 years of drag racing and AWD has taught me. You want peak grip without bogging down an ICE car, but there's no such think on an BEV car with "bogging" so any wheelspin beyond a slight amount on dry pavement would be considered excessive.

Wheelspin, even a minute amount as compared to a prior run results in slower 60ft times, resulting in slower 100ft times, resulting in slower 330ft times, resulting in slower 1/8 mile times, resulting in slower 1000ft times, resulting in slower 1/4 mile times....

You are 100% spot on, we've seen 3.3 seconds out of this car on dryer pavement.

Stale info my friend. The first M3P with new battery spec versions had this power drop off. Later fixed with an over the air update, presumably when engineers were happy with the data.

See the tests here (this same YouTuber reported on the loss of power earlier):



By the way, this test was done at low temperatures and wet tarmac, so pretty comparable to the m50 video I posted.

Probably Taycan GTS, Turbo and Turbo S. Different price level though. :

Yes, excessive wheel spin is never good. Are you suggesting the little chirp was excessive wheel spin?

We know on dry pavement, both can do 0-60 in 3.3 seconds or better in some cases, so they are pretty comparable on dry pavement.

Waiting for more dry weather acceleration runs.

In reviewing the i4 M50's video, it looks like TCS/DSC was still engaging itself up to 65kph which would tell me it's more than a chirp.

I was thinking the same thing too, the only competitors thus far are the Polstar 2, Tesla M3, and upcoming BEV C-class and A4 cars. Not sure what else is in the compact/mid-size entry level "sports" sedan class without stepping up to the next class of the Taycan/Model-S etc etc.
