Sensational effect. Really throws me back in the seat the few times I get to floor the pedal.
Merging onto the highway the rpms get up to 5000 and it is immediately over 105mph.
Noticeable difference from my wife's car which is a 2015 335i with just the MPPk
The extra torque supposedly to 430 throws the car forward and if you are in the right gear best acceleration is from 50-100.
You can feel the difference even with MPPk which I think should be standard on every N55. They have deliberately detained the N55 for gas mileage. How dumb!
I just added Dinan performance exhaust too and added more horses apparently?
Does the bmw MPE add power or just sound?

Just sound, it's just an axle back system.

That sounds awesome!
The MPE adds no performance, just the added sound. I am really hoping the MPPK and the MPE can give me the satisfaction I need.

Note quite sue why tracking a lease is particularly crazy.

But I may be missing something....

The 435xi has a great engine - more than enough for essentially everybody - and a very decent chassis. But, BMW's xDrive treatment really ruins the car, in my opinion. You have to take the base suspension and add DHP to firm it up. DHP, again in my opinion, is better as an answer for people who prefer a smooth-riding car and wish for it to zig here and there, than as an answer for a sport suspension.

So, in my opinion, a 435xi would have to have aftermarket suspension work in order to bring it up to par even with an AWD Audi, let alone a BMW M car. Some people enjoy that kind of aftermarket tweaking, others are revolted by the thought. Obviously none of it is lease-friendly.

I don't think BMW does a good job preserving the "Ultimate Driving Machine" in its xDrive cars right now. They are a little too heavy, marginal steering, and much too softly sprung.

I advise against the 435xi in general. If I were you I would test the RWD 435 against the M4 instead. That, to me, is a much more interesting question of performance versus cost.

Actually, I respectfully disagree. I feel like the M4 has been elevated to a level that is higher than the 335. Back in the N54 and N55 days, the S65 motor wasn't that much better than those, especially when the former were modded. Now, the S55 has a lot more power/torque, and room for much more.

The gap between the x28i and x35i has been diminished as well, being that the former is turbocharged and also has the room for more.

Now the x35i is still a great motor and car, and I would happily consider one, but at a price point (say 48-56K), anymore than I'd make the case to get a base M3. And from what I see from people's builds, the MSRP for some of the 335i/435i/GC hit 60K. That is a lot imo.

Just my $0.02

No doubt - it's nearly impossible to keep a 435xi under $60K. It's possible to spec an M3 out under $70K, but you'd have to be a certain kind of person to enjoy the car you'd end up with. It would probably need to have 18" wheels, a manual transmission, and a crappy stereo, for example. I never see M4 examples below $75,000 in the wild.

I simply think the 435xi in particular has a lot of performance compromises that people don't understand until it's too late, which the 435 does not have. Cost no object, of course I'd take the M4, but realistically it is at least $15,000 more car than any 435 when equipped remotely comparably apart from the drivetrain.

All these cars are too damned expensive if you ask me.

I have a 2015 435ix with BOTH the MI and MII performance packages...I never considered the M4 for the very reasons mentioned -- I live in Canada and value the xDrive over the extra performance in both the rain and, much more so, in the snow...I went further and bought winter tires for the car as well.

I learnt this lesson the hard way in that I use to have a MB AMG that was a blast in the dry weather but in the rain and -- even worse -- the winter (even with snow tires) it was a truly horrible experience.

I will buy an M when they put xDrive on it in the same was that Audi puts Quattro on their RS version (my last car was a TT RS)...worth noting is that while my 435ix is not as fast as my TT RS it is -- at least in sport mode -- plenty of fun to drive.

The 435xi is 0.3 seconds faster 0-60 vs the RWD 435i.

No argument. I wasn't talking about speed, or even on-paper slalom time. The xDrive cars just feel sloppy in front and larger than they are. Some of it is my own opinion of course.

WTF are you talking about. "Wasn't that much better than" the N54 and N55? You're not clever enough to be funny, but I certainly hope you're not serious.

The E9x had an absolute gem of a bespoke engine. There is no comparison between an NA, high-revving DOHC V8 and an uninspiring, under-turboed I6 which only makes torque. The F8x uses a glorified and N55...they're even 80% similar, per BMW official material.

But if you're thinking on simpleton terms equating power to "better", then sure...the S55 is better. That must mean it's also better than the engine in a Ferrari 458.

[ryanSTL]

if you can live without AWD and drive in an area where you can stretch its legs, get the M4.

i agree with most of the comments that a loaded 435 price-wise doesn't make a whole lot of sense. I was able to keep my 435 Gran Coupe with tech, premium, HK, M-sport, backup cam, HUD, comfort access ... under $56k. I needed 4 doors and do not care for the 335/M3 body shape & style.

I see some of these 335/435s optioned out in the high 60s and some M-performance optioned ones north of $70k. that is insane,... get an real M at that point.

M4 is probably my next car. Used or new will depend on when LCI happens and what's included.

Calm down. I wasn't make a joke or a quip - a modded N54 would destroy an S65 in terms of power/torque.

If you talking other components like suspension, transmission, yes the M3 was above and beyond a regular 335.

.3 seconds sure doesnt unless youre tracking and really good at it. I bet theres no chance you or any of us could equal those times (in manual anyway) .

[fecurtis]

0-60 is more a metric that lets you know how well a car will be at pulling quick merging or passing maneuvers for everyday driving.

As far as professional driving is concerned, it's not as important.

[crono06]

Agreed. I also believe that if the driver is good (and not an occasional track driver) the rwd version of the F3x cars will always get better lap times than the xDrive versions. On the track, where you never start from a dig, the xDrive doesn't really have any advantages.

That being said, in the real world to the average driver, xDrive will probably be much more beneficial.

In the real world, how many people are launching it from 0 MPH often?

[BimmerBoomer]

While I've owned three M3 coupes - E36, E42 and E82 - I'm simply not drawn to the M4. However, if I were my 435i xDrive - which is a good looking and practical car - would in no sense measure up. And no amount of modification would fill that gap.

LOL, no...not even close. 0-60 is the worst possible indicator of passing acceleration. It tells you how well a car launches from a stationary position, so the opposite of what you just said.
