Unfortunately, my carb is electronic and the machines to calibrate it are unobtainium..,... so it has to be hacked through manual adjustment.

I'm not sure what you're saying was false... but here's what I know about these engines. The 3800 basic design goes way back '78 (though it had relatives from before then), but it technically did not become what we know of as the 3800 until 1988. Various sensors had been added and changed over the years to make it more efficient. The series 1 and series II made other minor changes to the block, but it was largely the same design. It was a cast-iron block rather than the aluminum 3.6 liter. The Optispark distributor system was excellent in concept, but had a design flaw that allowed moisture to build up inside. Later versions and aftermarket replacements included drain hole to allow moisture to escape. People bitch and moan about Optispark because at the time they were used to the distributor sitting at the top of the engine and being easy to access. Optispark removed the necessity to access it as frequently as an old-style distributor, but it was moved under the water pump meaning that changing the distributor meant draining the radiator (!!) and doing a water pump gasket. It was just a convenience thing for the old-school guys. But I bet every single one of those guys would take Optispark over a timing belt driven Honda which was common at the time. A timing belt job on them ALSO included doing a water pump swap. @A Horse With No Name - The GM 3.6 issue are largely around the timing chain and service intervals. GM tried to extend oil change intervals on the earlier ones, but old oil would cause the motors to stretch out the timing chains to the point that the VVT couldn't compensate. Multiple manufacturers (Ford and Honda that I know of) have dealt with similar problems, so it's not a situation unique to GM. GM addressed it by strengthening the chain and shortening the service interval. Other than that, the 3.6 has been fairly reliable by my knowledge. Electric motors have fewer moving parts if that's what you mean by simpler design, however the electronics in them are more sophisticated and complex. There's also (usually) no multi-gear transmission to worry about. I've actually been to seminars on this subject. Car manufacturer are already aware and working on it. More and more manufacturers are going to go with hardened versions of mobile device software to run their cars. Let Google or Apple or Blackberry sort out the operating system level stuff and the manufacturer will handle the car running parts.

This has been my jam the past week

I’ll be canceling XM as soon as my trial membership is up. The stations I like are too repetitive and the others don’t interest me.

I’ve only owned it a little over a month and I’ve had it on trips 4 weekends out of 6. I brought back a small U-Haul trailer full of furniture from my grandmother’s last night and just dropped the trailer off. Going to give him the week off from commuter duty and let the Toronado fill that role the rest of this week.

It’s really just a Model/ trim at this point, so it can stay under GMC.

Always follow the money....

Interesting article. It's not that this technology needed to be invented, the concept has been around since the 60's. It's just that no one had been able to make a business case for it (i.e. how much more efficient or powerful or light would introducing more phases make it cost effective?). I can see multi-phase motors being a thing on planes, but I don't see a need to go to 12 or 18 in cars. Tesla has already shown that more power isn't an issue, so it would either be to be more efficient or lighter. That said, there are only incremental improvements to be made. Tesla might be able to get 5% more range by making a physically smaller motor more powerful and therefore weigh less. Having the motor virtually "shift" through 18 phases just to get up to 60 mph and back to zero probably isn't practical from a complexity standpoint. If I were to guess, 6 phases would be the most. Three phase electric motors have been around forever. The Volt has one, I believe (but cannot find proof for sure) that the Bolt has one. Telsas are all 3 phase (but the dual motor ones are different sizes, so there are effectively 6-phases in the car and the car can switch front to rear and back as needed). So this technology is the EV equivalent of adding more gears to the transmission. In this video, you can hear the first 2 phases of a 3 phase motor accelerating. The third phase you'll never hear the switch because you're doing about 100mph at the time. This is a later EuroSprinter with multi-phase motors. They sound like a saxophone playing up the scale.

I agree... further, not just lost, but obscured. Without being there, the manufacturers can show you only what they want to show you and even then only in a flattering light. Seeing the cars in person makes a huge difference and you also notice the things that the manufacturers might not want you to see.

I'm not sure I notice a significant difference yet, but I'm still running totally stock. It's also possible that you get a bigger bump in power with the 6.2 than I do with the 5.3. I think a CAI and tune will come later in the year, right now I'm in the middle of shaking up my finances with a new bank, new primary credit card, and new savings/investing strategy... so I want that to settle down first before I make more extra purchases.

They also haven't been on the market long enough to get any sort of temperature check. This is a bureaucratic problem, not an EV problem. Denmark put tax levies on petroleum powered cars and gave tax breaks to EVs in order to reduce greenhouse gas emissions. Someone should have had the foresight to say, "Hey! When we reach our goal, we're going to have to adjust this." Bad tax policy is not an EV's fault.

I actually preferred the look of the older one. It was much more distinctive compared to the competition. I’m done with small displacement turbos replacing larger NA engines myself, but this isn’t the best case scenario for that argument. The 1.8 was gutless and saw no noticeable fuel economy gain over the 1.4T. The 1.4T does roll on like a larger engine and would be perfectly suitable as a base engine in these. The 1.8 NA should have been dropped completely and a 1.8T should have been offered.

EVs aren’t consistent enough to form any opinion. You basically have Teslas and you have the rolling penalty boxes that look like eggs. Shocker, the rolling penalty boxes that look like eggs have poor resale. The Versa Note and Chevy Spark have terrible resale also because they’re rolling penalty boxes that look like eggs. But that’s the entire market of EVs right now, there is no middle ground like say an EV CR-V. So it’s pretty impossible to form any conclusions as to what an EV resale landscape will look like when more models come out.

On a different tack, one of the only things that bothers me about the Avalanche is how un-green of a vehicle it is, slurping down gasoline at 16 miles per gallon. However, the conversation we had here the other day about E85 made me do some figuring, and I think I'm just going to run E85 all the time from now on. It will cost an extra $125 every 10,000 miles to do it, but I think it's worth it in order to use a renewable fuel. Plus, of course, Moar Powah! Also, by using E85, I will be using less than half the amount of petroleum that a Toyota Pruis would be. In fact, a vehicle would have to achieve an average 83mpg to use as little petroleum as I do when running E85.

If the electrical grid fails, you still aren't pumping gas. I've been in south florida after a hurricane when no one had power... you're still not pumping gas. I had an extra 20 gallons strapped to the back of the Honda when I went down and I got gas at what was probably the last available station before the power outages and it took me two hours of waiting in line to get my 16 gallons. They wanted to fuss at me about the gas cans on the back of the car because they thought I wanted to fill those also, but I had filled them in PA before I went down.

Whatever the percentage is today and multiply that out by the number of EVs sold in the future. It isn't a knowable number at the moment.

No. I like the powertrains in the EVs... I like the Tesla powertrain. The Bolt EV is an absolute hoot to drive. My issue is the body they put them in. I wouldn't buy a Bolt EV even if it was powered by a Blackwing or a 6.2 Ecotec. I buy vehicles I like the looks of first, powertrain second. I bought the Avalanche because I like the Avalanche. The 5.3 I would describe as adequate at best, but I would have definitely preferred at 6.2 or even an EV if those were options. Lots of people like the Tesla looks enough to buy one. I do not. I think they look like a soulless jellybean and their interiors are spartan... but so does a '99 Taurus or Lumina. I wouldn't buy either of those either. Put the Tesla powertrain in a CT6 and I don't care if I can't afford it, I'll make it work somehow. I really wish AWD wasn't a requirement for me or I'd pick up a CT6 Plug-in.

The battery degradation issue is widely not an issue. In hybrids and EV, the cars are wearing out before the battery does. NYC’s and LA’s fleet of hybrid taxis age out before the battery dies.

The way the bans in Europe work is that you are only allowed in the city center or congested areas if you have a certain color registration sticker (theirs goes where our inspection stickers go). Some of the bans are time based to keep heavy polluters out during rush hours. But basically it works like this, only vehicles that meet the emissions requirements get the best sticker that can travel to city center at any time. If the police catch you driving (not parked, actively under power) and you have a banned sticker, you can be heavily fined. One of the only exceptions I know of is medical emergency, but there may be others. Delivery and work trucks also get special hours for operation. Now all of the places that are planning total bans are the cities, specifically ones that have fantastic public transit, so your scenario of Aunt Millie who lives on the side of a remote mountain and only goes to a general store in a town of 1,000 doesn’t apply. Also, classic cars get emissions exemptions as long as they’re driven less than a certain distance per year. Most people live in cities in this country, more than half. So I still maintain that EVs will be suitable to 80% of non-commercial drivers by 2030 without much difficulty. They’d be accepted by 50% of drivers if the financially accessible “middle class” ones didn’t look like stupid eggs.

I think I’ve pointed out multiple times different solutions for different lifestyles.

If you can't afford an 8-year old Leaf, you can't afford a car. 2013 Ford Focus Electric - $4,868 - 74k miles 2014 Chevrolet Spark Electric - $4,995 - 62k miles and more torque than my Avalanche(!!) There are 189 EVs for under $7000 and under 75,000 miles available on AutoTrader right now.... so maybe we can move past the "EV's aren't affordable" trope. Unless your house is on an electrical panel pre-1990 (and I fully admit that many houses are), the cost to install at charger averages $1200. It costs roughly $1,295 to fuel a Toyota Corolla for 1year/15,000 miles at 2.59 a gallon and 30 mpg average (local average price). Charging at home costs so little per mile compared to fueling with gas, that ICE maintenance more than exceeds that cost.
