... and then 26% of it was a tax rebate. If you figure my roof otherwise would have been $50,000, and subtract the tax rebate, it cost me $42,500 beyond a normal roof. Subtract a whole house generator cost from there (which I didn't get because this serves the same function), and it cost me $30,000. ... and $30,000 is a pretty fast payback period with no electric bill, no gas/oil bill, all of our EV charge bill, and the electric company writing me checks every month.

For context of the electric company writing me a check each month, I'm on net metering with this as my price structure:
So, when the grid is online, this is how my house works I charge the car and house batteries every night at super off peak-- so I pay $0.03 per kwh. I drain the powerwalls to 20% into the grid every day, at peak pricing-- so I get paid $0.23 per kwh from the batteries. The powerwalls are smart enough to distribute the drain so they hit 20% at 6pm-- so any power we actually use during that time come from our own batteries. Our water heater is also programmed to avoid heating water during peak pricing. In short, that's ~43kwh/day just from the batteries charging overnight at super off peak and discharging on peak-- so $8.60 per day from that In addition, much of my 19kw of solar production occurs during peak pricing-- so I'm generating 10-19 kw per hour in that period off solar when it's sunny-- ~45kwh per day when sunny, so ~$10 per day from that (on sunny days). Combined, we get paid $250-400/month from the electric company, even with all our utilities being electric and most of our miles being on an electric car. (this was what I meant earlier when I said it's tricky to calculate what the i3 actually costs us to drive) I limit the battery discharge to 20% for two reasons: 1) batteries wear much faster if deeply discharged, and 20% seems to be a reasonable stop point to avoid that 2) if there's an unexpected power outage, I don't want to be without power. 20% of 4 powerwalls is generally enough to always get me through until the suns out to recharge them again. The powerwalls have a feature called "storm watch". If weather is such that a blackout is more likely, they will fully charge themselves off the grid so that they're ready at 100%. When the grid is offline, the house functions as you'd expect-- charges from the sun, uses power from the batteries. In the case of extreme cold and no sun, I do have a wood stove for backup heat, but that has not yet come up. The Tesla roof has a warming/self clearing function, so you don't have to worry about that.

I know what you mean about the turbos and the steering in some ways, but the regular E9x steering was already a step down from E46 and is faux-heavy. I find the M2 Comp steering to be overall as good as the regular E9x, but different. I can't comment about E92 M3 because I don't have enough time in one to judge it. Frankly, the Z4M destroys all of them in most categories, but you already knew that. I would definitely take an F22 M235i over an E90 328i or 330i. It might be a question against an N54 335i. The E82 135i N54 is what I would pick of that era anyway if we're talking non-M cars. Engines I've driven, excluding the V8s: S54 > S55 > B58 > N54 > N55 > N20 = N52 The manuals in all of them suck in different ways but the Z4M was the least bad. I suspect M2C will be best after installing an SSK and CDV delete. Last edited by chris719; 06-30-2022 at 11:41 PM.. |

Yes, that price included install. So, of that, the batteries are $7500 each (free install with solar roof), minus 26% tax rebate = $22,000. Batteries are warrantied for 10 year, so that's their shortest possible life. That is part of why I'm doing the charge when cheap, drain into grid when expensive thing, though-- batteries do age out, so they need to pay for themselves before then. At $8.60/day, I'm break even on the batteries in 7 years, so everything beyond that is gravy. I expect them to be considerably cheaper by the time they need replacement: I think it's also reasonable to compare the battery expense to a whole home generator, which never breaks even, requires service, requires fuel, and is annoying when running (though much less annoying then not having power)... and, in my experience, often doesn't actually turn on when needed.

The N52 came in a lot of specs and chassis-- from 174hp to 268hp, and in chassis from 3050 to 4300 lbs. So, you can come away from it with a lot of varied experiences. But, in the 128i in particular-- if you add BMW's 3 stage disa (from a higher trim N52), headers, and a tune, you're at 300 factory reliable NA BMW horsepower in a i6 that weights freaking 328 lbs. Almost 150 lbs ligher than an S54! I'd kill for that kind of weight off the nose of my M3! Combine that engine with a properly optioned 128i, and you have a car that is 3050 lbs stock- and sub 3000 lbs with just runflat delete and light weight wheels. Add M3 subframe bushings, so the body is actually connected to the suspension, and you have a great driving little car. More factory mods possible if you want more, beyond that-- all the M3 control arms are bolt on, as done on 1M. 128i steering is great as stock-- none of the fake heaviness stuff they did on the e9X. 135i is a 300+ lb penalty over 128i, and all the turbo engine dynamics I don't want. But, yeah, put a low factory trim N52 (e.g. the 228hp one in the e9X 328i) into a heavy chassis (sadly the e9X is a fairly heavy chassis-- e60 is only 72 lbs heavier optioned like for like), and I could see why you came away not overly impressed.

Yep.
... but 300 lbs lighter. And smaller. Both of which means it drives significantly better.

A no sunroof (50 lbs for sunroof), no idrive (40 lbs for idrive), manual trans (60 lbs more for automatic) (that's what I meant when I said properly optioned earlier) 128i is 3050 lbs. I know this because my brother had one and we put it on my corner balancing scales. I haven't had a Z4MC on my scales, but according to BMW it's curb weight is nearly 3300 lbs. ... unless you meant non M. Those are lighter. I'm assuming that's not what you meant, because very few (<300?) were sold in this country.

I'm sure you're right on the transmissions. MT usually feel better inversely proportional to the torque they need to handle. Z4M shift into second is awful but it's good other than that. I've driven other NA M engines, I just left the V8s off as I noted. S65 is a gem and S62 is great. The only 2001+ M engine I haven't ever experienced is S85. |

I personally think an N52 is a positive selling point in a BMW. I'd take one all day over any of the turbo cars. BMW + turbo = $maintenance$.

Count me on Team N52! I won't say never, but I can't imagine having an ICE car without one. I actively sought out the one year that F10 Fivers have the N52 (2011) for my wife's car (everything else is bad in it, but engine is good!), and am casually looking at 2010 E70 X5s as that's the last year they had the N52. The N52 perfectly meets my needs, and other than gaskets made of crepe paper, a great mass-produced engine.

On what world does a stock 128i weigh a crack over 3050lbs? BMW lists the curb weight at 3208lbs and the 135i at 3370lbs which is what one would expect with the additional weight of the turbos, ancillary cooling systems, larger brakes, wheels, and tires. It is not 300lbs. LOL. It's not like the N54 has an iron block or something.

It really depends on the year and model of turbo BMW. I've owned my 2016 M235 for 6.5 years and 65k miles. It's been crazy reliable. Nothing as broken on it. Nothing. No leaks, no weeping seals, etc. I've done oil changes and filter changes, coolant change, a spark plug change, and preventative maintenance like a belt tensioner replacement, belt replacement, and coolant overflow line, all work done under an hour less than $300 in parts. My front brakes are needing replacement after 65k miles. I ordered all OEM BMW rotors, pads, and a wear sensor for $500. This car is driven hard and has been making 50whp and 70wtq more than stock for years. I really can't complain. I've owned lots of Japanese cars and the M235 has been more reliable.

Just a secondary point, the I6 balance helps with harmonics, but I dobut there's any real world correlation to reliability. BMW has produced several unreliable I6 engines, and I'm not sure any of their engines are up to Toyota standards when you compare like-for-like. N55 is "reliable" if you don't care about PITA things like the oil filter housing gasket, valve cover gasket, oil pan gasket, etc. I suspect the same is true for N52.

Other than S65 and S85 which are fatally flawed designs, there's really not that much more maintenance. N52 will still be a pain in the ass with the same OFHG, valve cover gasket, oil pan gasket, etc. as an N55 and S55 but it's still an N52. If I wanted N52 output from a car in 2022, I sure wouldn't put up with the normal BMW BS. N54 is one of the least reliable designs in modern BMW history and it's not an M engine. At least it's a pretty nice engine when it works, but still no longer worth the trouble. What premature maintenance does an S55 require that your N55 doesn't? If anything, the gaskets seem to last longer on the S55, especially the oil filter housing. Last edited by chris719; 07-03-2022 at 03:36 PM.. |
