New BMW X3 M40, INSANE power delivery (2024)

I've got enough track time to know Im not Randy Pobst, and I have no clue how much track time you have, so Im not sure it would prove anything aside driving ability, but my GT is so far ahead by the numbers that if I lived closer, Id do it. Sadly, its a bit annoying of a drive to Co.

Well, keep doing what you doing, take two brochures and race them across the table.
and wait another topic where you need to justify yourself purchase of that Sorento.

Im very familiar with it. What Im telling you is it doesnt make it much quicker in any sense. It feels better and improves throttle response, by and large, which isnt going to show up at the track, but more in daily driving. But you race the two, and it wont amount to much. Mazda did the same thing with the cx90 I6 3.3 turbo. It didnt do much for it empirically.

i don’t think you are familiar, but you definitely not getting it.

Im very familier with it and its nothing like how you're passing it off. You're acting like its some sort of turbo or supercharger level of effect. Its a mild nudge. Like running 93 octane instead of 87 in a car that can tell a difference.

It doesn't really need justifying other than why I need such a capable car for a daily, lol!

I tried, but…

We actually do know why you need it.

 

[Ws6]

We actually do know why you need it.

Because I can, and I wanted it. Simple nuff.

 

[Ws6]

I tried, but…

Yes, you tried to explain how 11hp is worldchanging and failed.

 

[Ws6]

You lack a fundamental understanding of the bmw system. Its not adding 100+ pounds of torque. Its just filling in a hair of turbo lag. If you were to look at the dyno sheets with and without it, they wouldnt be much if any taller with it, they'd just shift to the left a little. If you could brakeboost the car it would be way more effective than what this does, for example. It just helps a bit on tip in. But the b and a 58 really arent laggy anyway.

Nah, you are right. Dyno, gym, 0-60, yes, you wanted, you can, but we know why.

Yeah, some people enjoy performance. We like speed and power and all that jazz. We also like being healthy and capable. I fail to see the issue.

Maybe one day. Same like other issues.

Umm, guys, straight from the horse's mouth:

48-Volt Electrical System.

1. Introduction.

The BMW Group has for years been developing a variety of technologies to reduce the overall CO2 fleet consumption. Among these technologies are micro-hybrids, in which the measures of EfficientDynamics are implemented. Another important milestone was the development of plug-in hybrids (PHEVs) and battery electric vehicles (BEVs). Now we are witnessing the development of mild hybrid technology.

The 48-Volt System is being introduced in the G30 with the BMW 540i and 540ix as of July 2020 tobe followed by G20 with the BMW 340i and 340ix. The 48-Volt System will be included on all future vehicles equipped with a B58 engine. The new 48-Volt system will also deliver new functions whichserve to increase comfort, efficiency and dynamics.

The introduction of mild hybrid technology produces new functions with noticeable customer benefits:

• Reduced CO2 emissions

Braking energy is not lost, but instead electrically recuperated. The combustion engine is supported in driving mode and operated in more efficient operating conditions. This results in consumption reductions in customer operation of around 0.3 l/100 km.

• Improved automatic engine start/stop function (MSA)

The powerful 48-volt starter motor generator produces a noticeable improvement in starting time of approximately 20% faster to improved comfort in terms of acoustics and vibrations during the starting procedure. The starting procedures are now barely noticeable. The first engine start of the day is done by the conventional 12 volt pinion starter motor. If the engine temperature is greater than 60 °C (140°F), the engine will be started by the 48-volt starter motor generator.

• Engine off coasting

In so-called "coasting" the combustion engine in normal situations no longer continues to run at idle in mild hybrid vehicles, but is instead switched off completely and the drivetrain is decoupled in order to utilize the vehicle's kinetic energy for motion. Compared with the idle coasting function the consumption advantage can be further increased by switching the combustion engine off. Restarting is virtually delay-free thanks to the powerful 48-volt starter motor generator.

• Dynamics advantage thanks to eBOOST function

In partial load operation the starter motor generator supports the combustion engine as an electricalmachine. Thanks to its delay-free power output, the electrical machine improves the acceleration build-up, i.e. the spontaneity of the drive. In response to full load demand the electrical machine can incertain operating ranges briefly increase the drive's overall power by 8 kW (10 hp).

Excerpted from the ST2007 Technical training document, not a glossy magazine ad.

No comment from me, except that I wouldn't be chomping at the bit to buy a vehicle that has it, regardless of benefit, based on the additional complexity alone.

The starter motor generator is cooled from the main cooling system, and the Li battery/DC controller unit have their own dedicated cooling system with a separate radiator and driven by an electric pump.

None of which does any favors for a typical, already porky modern BMW either.

I dunno, Toyanon is a force to be reckoned with on here. Sort of counter to the haters, these are more like fanatics, lol.

Toyanon side of the force is a pathway to many abilities some consider to be unnatural

I did something similar down here at the Circuit of the Americas. Got a chance to put an M3 and M4 though its paces. It was high 80s F in the morning and by noon it was mid 90s F. These cars went 150mph with the AC on full blast like I was going down a highway at 60mph. Group after group did that, the cars were never shut down.

No electric can do this and that's why they only demo the 0-60mph.

Wow, never crossed my mind, excellent point.

Which issues you had with modern BMW?

 

[edyvw]

Wow, never crossed my mind, excellent point.

Since 2012 BMW has oversized oil cooling system. E90 335 with N54 and N55 had issues on a track with oil cooling. BMW did not really think thru high(er) altitude tracks and it was a press debacle in 2007. With F30 all I6 engines had radiator-type oil coolers or two, depending on the package, while all G series have one or two radiator type oil coolers, together with a heat exchanger and electric thermostat.
The electric thermostat (instead of an electric water pump) was also in F30 with B48/58 engines. Basically, no engine in BMW since 2016 needs any cooling modifications for track purposes. Still waiting for porky issues since 2016.

So the B58 and S58 are excellent Motors. A few simples mods and 600hp is easily made. Problem is, its a BMW, which means its going to leak, might loose a diff, or something else. BMWs are down there with Alfa Romeo in terms of reliability. You don't see alot out of warranty lol. BMW. Break my Wallet

Wow, that's really funny! Did you think of that yourself?

 

[JHZR2]

It’s incredible what modern cars can do. Especially EVs. But the modern ICE is incredible. Even a decade old MT v6 family sedan probably outperforms most muscle cars of the prior eras. The issue is that it’s almost not usable. Certainly without risking very illegal behavior.

The old adage that it’s more fun to drive a slow car fast, I think applies. Even in my 135i, slow by the parameters given by OP, I get to illegal conditions that are dangerous, way too easily.
