I think in this particular vehicle it is partially due to the dct, it provides quite a bit of engine braking. My 335 said 80k miles for brakes ... then again these are bigger and the car is slightly lighter

That engine braking might well be regen, bro. I thought I read that all BMW's got regen starting with F30.

There is a small motor integrated in the hubs that charges the battery once you hit the brakes, but it is no where near actual “regen braking”. This car has shitty non linear braking thanks to the dct. My F30 did not. The 8 speed is far smoother

That's saving your brake pads considerably, :doe:

If that’s the reason that’s pretty awesome. Seamless tech that extends pad life

It's brilliant, IMO. Think about how much energy is wasted in braking. From what I understand, during braking, BMW's "disconnect" the alternator so there's zero drag on the engine (improving efficiency) and uses the power coming from the "brakes" to charge the battery instead. It's a little thing, but pretty clever. Saves wear and tear on brake components and is more efficient. Adds complexity, but :notsure: how much.

I notice the impacts of regen driving the Volt. It's amazing how long the range can go in stop and go traffic. Put it in heavy regen mode, and you can drive in traffic without taking your foot off the go-pedal. When I need to press the brake, I sometimes will take a look at the power meter and notice the regen CRANKED. The wheels on the Volt look brand new and I've never even washed them. The vast majority of braking is regen and you can't even tell, and applying that to gas powered cars like BMW has is pretty clever.

Yep the Mazda’s have a similar system. And I think it’s coming to FCA cars with the alternator being a motor generator unit.

Regen or KERS is fantastic tech.

The FCA alternator one is really interesting. Effectively a belt-driven electric motor that just assists the engine on take-off. :notbad: execution for a super mild hybrid.

:dat:

I'm surprised at how slowly this sort of tech is creeping in to mainstream cars though. Maybe the fuel saving return just isn't good enough for the extra cost of batteries or capacitors or whatever else is needed to support it.

Cost breh... :iono: too expensive to engineer into a vehicle with a $500-1500 profit margin.

Especially since the fuel economy impact is minimal. Now, every little bit counts, especially when you want to sell 300k bricks per year.

Right, when you volume seller is the size of a children's playground on wheels if you can eke out 1 MPG better your CAFE stress will be eased quite a bit.

Alignment gurus could you please chime in, it looks like my car is wearing both inside and outside edges.

One would think that means the tire pressure is too low but it is correct 31psi vs 32 required.

Car tracks 100%. Straight... I don’t want to get a BS excuse from a tire shop or a swindle from the :dillerman: for a $299 alignment.

Any insights as to what type of adjustment the car would need ? Or is this “normal”

Could be toe wear on the inside and normal wear from hard cornering on the outside. Hard to say without measuring it. That being said, cranking them up to 36 psi will slow that wear down in the meantime.

The odd part to me is that both are almost identically worn. I actually thought of rotating them side to side since I saw the exterior wear and figured it was me driving it like a douche, but then once I got them fully turned I noticed the inside wear as well.

The ride is rough at 31psi, I think the windshield will crack with anything over 35 :lol:

Yea... I'll be getting at least a check in the next 2000 miles. My oil change is due in about 2 months, so I'll have em check alignment and rape me for a set of tires. I think I am not going used this time since these look like they last ~20k miles... which is exactly how long i'll have the car for before lease turn in.

So this is an interesting piece. I was crawling around to see if my car was "lowered", (doesn't seem that way) However check this out!

It looks like the middle 2 of the 4 exhaust pipes are "muffled" while the exterior two are straight through.... when in sport mode the car gets pretty damn loud. I can't believe BMW essentially installed a factory muffler bypass! :mindblown:
This car literally needs no mods. :triggered: bmw took care of everything

quoting myself to bring it up to the top... looks like costco is running a tire sale ~1200 for a set of 4 installed after tax. :notbad: Gotta figure out if I'l go with PSS or PS4 or whatever that new one is...

Re: Bolded part....


Umm.. Haven't you see the C6 or C7 with the NPP exhaust? This is old, old tech. The MK6 Golf R had a similar setup, as well as my M235i.
