i also test drive a few EVs. those things are crazy responsive with their throttle.

Yeah EV’s are on a whole other level in terms of get up and go from zero. But they got no soul!

Or range

I don't need the full beans sportiness of the C63. To be honest, if the Cayenne had a better soundtrack and slightly better dynamics, I'd have been super happy with it. With that in mind, it seems like the M550i might be just what the doctor ordered. Better handling than the cayenne, definitely better soundtrack. I'm not tracking it and when I go take it down a windy road, it seems like it shouldn't disappoint.

When people complain about throttle response in the M550i, I am left scratching my head. 0 to 60 in 3.5 seconds is pretty damn stout in a 4400 pound car. What exactly do you mean when you have a issue with throttle response? In sport mode, I get an instant downshift and throttle response no matter how fast or slow I am rolling.

And with respect to loud exhaust, I’ve driven fast loud cars my whole life. I relish the toned down exhaust tone.

I have no issue with the throttle response in any of the modern BMWs I have driven when in sport or sport plus; that said, throttle response/sensitivity and 0-60 times are not one and the same.

A bizarre comment.

Did you read the rest of my comment? My education is in mechanical engineering and am well aware of What throttle response is. You seem like a douche… is that bizarre?

I read it all. And here I see insults and uncontrolled emotion instead of anything related to engineering.

The 0-60 times are calculated with launch control, so throttle sensitivity in the other modes means little. Furthermore turbo lag related to atmospheric conditions complicates things in normal driving.

Have a nice day.

I see (Larry) Nassar is making more friends around here with the passive, condescending I know more than you posts. I’m still waiting for proof that starmarked tires cost more than non starmarked. Shut him up on that one, but he totally ignores when he’s wrong and talking out of his ass.

Stand up guy we have here.

I guarantee that I have been involved with motorsports longer than you are old. Spare the lecture and emotions (nice projection). I forgot more than you’ll ever know. Don’t try to razzle dazzle me with your nonsense.

Any time you want an education about vintage or modern drivetrain mechanics/electronics/fuel injection give me a shout….we can break out the adiabatic efficiency graphs to better understand the impellor design and associated turbo lag that you referrenced. Bring your thermodynamics, calculus and differential equations books, you’re gonna need them.

i just drove my M550i for 4 hours yesterday.

when the car is stopped at the junction, at some point you'd want to pull out of the junction.

do you press the gas pedal 1% ? 5% ? 10% ? 20% ?

whatever % you press, nothing happens for half a second. it really doesn't matter how much you press it.

nothing happens for half a second, then you feel the car make some noise and then half a second later, it moves - depending on how much you had pressed the pedal. and it's not consistent either.

sometimes it starts to crawl. sometimes it makes a clunk in the gearbox and it shoots like a missile, causing everyone to throw up (if i have passengers). at no point does it move how and when i want it to move. and not before 1s later would you know what the car will do.

but once it's moving no issues. also if i hold the brakes and gas the pedal and build boost, release, it will shoot like a missile. 3.5s every time.

[alexxs]

Can it be because of the gearbox / torque converter? A 4.4 V8 should start pulling immediately, even until it builds boost.

I would get that checked out, it’s not normal.

they intentionally programmed the electronic throttle response to be shite. if you google m550i throttle tip in lag you get an entire page of results

this thing had enough power to challenge the previous M5 when it was released, perhaps that's why they did this handicap

[alexxs]

I have these two on the shortlist. Since I'm not that familiar with BMW options, could a kind soul take a quick look and advise if anything critical is missing ?

Makes sense for them to do this, but then the fix is incredibly easy with the myriad of pedal amplifiers around. Not to mention a normal remap.

The only time I would have an issue like that is to prevent wheel spin in the rain, sand or snow. mine is pretty damn snappy. I’m curious to see if you deactivated traction control how it would behave.

Done that, no difference to the take off from stopped. Tried every setting from TC, sport, sport plus. Suggests to be a electronic throttle programming issue that sends to affect some cars. Thing is, I'm not the only one. The internet has pages of this lazy behaviour.

You sound like a candate for a pedal commander. Dinan makes one. I’m not a fan of these, but it may help if you think the issue is software related.

I remember there was a recall for this… forgot what model year it was for

I pointed out two things that cause throttle lag in these cars. You've emoted.

Have a nice day.
