With snow tires? It's great till you run out of ground clearance.

Significantly better than the M5 with snow tires because...
-narrower tires (narrower is better in the snow)
-more rear biased weight distribution (wagon weight penalty is all on the rear)
-the M variable lock from the M3 works better in the snow than the LSD in the M5-- it will direct up to 100% of the power to the tire with more traction, whereas the M5 will just spin like an open diff if one tire is on ice
-the MK60 DSC from the later M3s (which is what's installed in this) is MUCH better than the older DSC in the M5
-I run XIces (dedicated snows) on the M3 wagon vs Pilot Alpines (performance snows) on the M5, because when I ran non performance snows on the M5 I toasted them in less than 2000 miles because of its weight and torque... and my inability control myself

Interesting. I would have thought worse than the M5. I had a Volvo turbo AWD wagon when I lived in CO. Great ski car that would pull like a boss up the mountain. But I had the rear get loose a couple times just going slow turning through an intersection. Can't remember the exact tires I had on it, maybe just all seasons. But I attributed the spinouts to the long wheelbase (moment of inertia).

Assuming there's merit to the longer wheelbase is worse in the snow theory (I have no idea if there is), the e46 coupe, vert, sedan, and wagon all have the same wheelbase-- and all 4 are shorter than the e39.

But, I'd blame your no season tires

I burned through my rear PA4's in one winter on the M5 (5-6k miles). They wore like I had them over-inflated (centers were much more worn than the edges), but I only had them at 38 psi. That's why I was asking what pressures you were putting in yours. That being said, I also found myself unable to control my right foot at times.

I kinda thought a longer wheelbase was easier to handle when the back end starts sliding? (more time to react?) Maybe not as easy to reel it back in if it starts fishtailing? I imagine weight distribution plays a part in that.

Obioban: your signature line says your M5 is <3800 lbs. Where did you remove weight?

Wheels, tires, unused electronics, secondary air pump, and driver (BMW's curb weight includes a driver and small bag).

We have a kid coming, and don't want to subject the M3 coupe or M5 to it.

So, bought a new car, M5 is going to become more of a garage queen.

New car:
-carbon fiber monocoque
-<2800 lbs
-rear wheel drive
-rear engined
-no turbos
-no automatic trans
-super low COG
-seats 4 adults

En route, getting delivered tomorrow

Congratulations! Having kids is a special experience!

Unfortunately, they are a bit more difficult to diagnose than anything made by BMW...

Cheers, man! Also - enjoy the i3

Babymobile update...

The basic thought process was this...
1) inbound baby in a couple weeks
2) baby's are disgusting and ruin cars
3) I don't want them ruining and of the M cars
4) a slightly used (CPO 2017 in this case) i3 is cheap enough that the money we're not spending on gas 100% (and then some) costs the cost of it over 3-4 years, so long as we actually drive the thing
5) They are also essentially maintenance free driving (so long as you don't get the REX), which will be useful to my decreased free time. No engine, fuel system, transmission, etc vastly cuts down on upkeep. E.g. BMW's free maintenance covers two things on this car-- wiper blades and brake fluid

The i3 is kind of a cool car in a lot of ways. Ways that would be much cooler with a high revving, NA engine, but cool either way. E.g.
-Carbon monocoque
-all the panels are plastic or CF.
-total weight of <2800 lbs for a full functional 4 seat car (took it to dinner in comfort last night with me (6'4), my brother (6'6), my super pregnant wife, and my brother's wife)
-rear wheel drive
-50:50 weight distro
-super stiff chassis
-instant throttle response
-super low COG

My option needs were pretty specific:
-94aH battery (so 2017 or later)
-No REX (adds 300 lbs, maintenance, seemingly 99% of the failure points)
-HK stereo (because my wife really cares)
-no sunroof
-"tera world" (for the leather interior, instead of cloth interior)
-never smoked in or had an air freshener installed
-not silver
-20" wheels... because that's they way you can get summers (as opposed to all seasons).

Since most cars are REX and/or have the cloth interior, it was actually pretty tough to find a car. I quickly gave up on finding one locally (seems like very few were sold in this part of the country). After 6 months, I finally found a car in Florida that met my needs. M3F member Dave B went over to check the car out for me, test drive it, and make sure it didn't have any evidence of a former life owned by a smoker or air freshener user (it didn't). So, after 2 weeks of the dealership being the worst I've ever dealt with Lauderdale BMW Pembroke Pines), it arrived at my door

Pictures from the dealer:










Wired up the garage with a 240v charger (0%-100% in ~4.5 hours):




Arrived:




Car in the garage for the first time:



Until the kid arrives, I'll be using it for my daily ~100 mile commute. Including today. Initial impressions:
-the car feels incredibly solid.
-It's weird to drive an EV by a real car company. Previously I've only driven ones that... aren't quite complete cars yet
-it's NOT slow. Not at all.
-it feels rwd, in every way you'd hope for
-steering feel is typical EPS, aka not great
-no engine sound is very strange. Great for DD, remarkably detracting from driving hard
-94mph top speed is seriously annoying. I'm going to try to get that removed, or at least raised the i3s's (same engine and battery) 100mph.
-interior, in tera world form, is really nice
-my driving style is not efficient. The Connected Drive app rates your driving efficiency on a scale of 1-5 stars. I'm averaging 1/2 of a star.
-regen braking takes some getting used to. It also makes the car feel strangely heavy, as if there's a ton of friction slowing you down
-LED headlights are bright!

Mods I'm considering...
-DIY trunk extension (into the area where the REX engine would be)
-bimmertech MMI carplay retrofit box
-OE BMW sunshades on the passenger rear seat
-Britax car seat base on the passenger rear seat
