RE: Duramax vs Power Stroke Fuel Economy Tow Test and Drag Race

I still want to see a direct comparison between the diesels and the gas engines.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

It would appear that Musk is very like Edison, a genius at being able to surround himself with people who can solve the problems he thinks up. It's very unlikely he has the skills to do most of his feats, but he has the sense to find people who can. Rocket scientists need jobs too. What do you base that on? Of course, one man can't do everything but from I have heard in the early days he personally solved many problems when his engineers got stuck. Finding and enabling good people is a significant skill too.

RE: Nikola announces electric pickup truck

At least it looks good compared to that ugly thing Musk designed... :B 400.000 thousand people who ordered Tesla truck would disagree. :B I wonder if Musk will cover eye surgery on a truck so ugly it can cause retina damage..... :B:B When you want to discuss an entirely different topic please start a new thread.

RE: Nikola announces electric pickup truck

A whole lot of brave talk with no apparent substance. I don't know of anywhere that I could get fuel for it. At least I can charge an electric car in my driveway.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Mirai is a good case study in hydrogen. Been running for years. Good luck.And some unhappy owners, lol.From what I read Mirai sell on carpool lane access and free fuel. Then they find out what a PITN hydrogen actually is. I want them to succeed though. Extracting clean fuel out of water is simply a good idea. But that explosion risk is just too **** scary. Hydrogen rises very quickly when released, unlike gasoline. As a result hydrogen fires in open spaces are not very dangerous. Plus, the fumes from either the fuel or the combustion are not dangerous. The is some danger if the fuel tank explodes since it is a large pressure vessel but that should be manageable with a secondary fiber wrap. "Then they find out what a PITN hydrogen actually is" Hydrogen can be a real annoyance in that it has such small molecules it is hard to keep contained. If you leave a tank of hydrogen very long there is a very good chance that it will be empty when you come back. Plus, the hydrogen molecules penetrate many metals and make them brittle. You have to be very careful of your material selections when working with hydrogen.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

To get to the topic of this thread Tesli semi deliveries could start as soon as June of this year. Tesla deliveries expected in Q2 "Kuhn said it is his company's understanding that Tesla will begin delivering local semi-tractors by the second half of 2020 — perhaps as early as the end of the second quarter. Six are expected in the first round, with six more on option if they work as intended." I would think they will want to keep the fleet small and controlled until they get the bugs worked out. I’m betting they are already installing the private Megachargers. The Megachargers like the Superchargers are apparently a stacked modular design. They literally consist of the same chargers that are built into the model 3. Just stacked for aggregate output. Keeps it simple for parts, redundancy etc. In other news. Tesla stock is hitting on 900 bucks this morning. Another bad day for shorts. Never a good idea to bet against a guy who lands rockets on barges. :). Still don’t think first quarter will be good though. Elon said 6 months ago that first quarter 2020 will be tough. They had to shut the line down for something like 10 days for what is suspected to be the model Y line configuration. 10 days is like 12000 cars. Ouch. And my understanding is that the factory in China is shut down due to coronavirus. Some really bad luck there. Now the avian flu is making a resurgence.

RE: 2020 Ford 7.3L Ike Gauntlet

Chevy 6.6 with 6 speed for reference. It looks like the 10 speed transmission may have made a HUGE difference for the Ford. The Chevy got down to 25mph before downshifting. Spoiler: 11 minutes 53 seconds. 2020 Chevy 6.6 on the Ike More reference: 2018 F150 with 3.5 Ecoboost towing 9,500lbs Ecoboost on the Ike Quick summerary. It easily ran the speed limit at 3,500rpm, just loafing with a speed of 7 minutes, 58 seconds. Gave 3.5mpg. Adjusting for the load, inline with the 3/4 ton trucks. I wish that they had loaded the trailer to the max weight so the that comparison would have been better. One more reference: 2017 Ford 6.2 towing 11,000lbs Ford 6.2 on the Ike It only got 2.6mpg towing a much lighter trailer

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Check your shorts, TSLA closed today at $640. Might be a favorable time for a capital raise.... Although probably not needed. Elon stated that they are already spending as much money as they can manage properly and have it covered. However, the situation in China shutting down his brand new gigafactory could have ramifications that nobody anticipated.

RE: New used truck

Can you tell how much of the perceived roughness was from the rear vs the front? The dually has two more tires(with steel rims) and a heavier axle so a lot more unsprung weight. That adds to the roughness plus it probably has stiffer springs and shocks to handle more payload even before any payload packages are included. The added noise surprises me.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

To get back to the subject of Tesla semi's, from what I heard in the annual report Tesla is still battery constrained and doesn't have enough batteries to assemble the semi's. So Tesla is focusing their efforts on increasing battery production before adding more product. One goal is to increase production at gigafactory 1 to 54GWh per year. GF1 production to increase I see this as their ongoing challenge. 2020 will be a balancing act of model 3 and model y production while being limited by battery production. I see model 3 production being sacrificed to enable higher margin model Y production. I think it’s already happening as model 3 waiting list in Canada is already back to 10 weeks. Each semi uses the equivalent amount of batteries as 5 model 3’s or y’s. It will be interesting to see how they balance all this out until battery production comes up. I wouldn’t be surprised to see 3 month waiting lists for 3’s within the next half year. Any new market expansion is probably out until the German factory comes on line. California still has to supply China with all models except the model 3 SRPlus. I'm excited about Tesla's acquisition of Maxwell. I hope they will come up with flux capacitors that will extend the range of batteries and then eventually make battery unnecessary at all.:W They do have some battery tech with lots of potential. Hopefully we will hear something about that in the next few months.

RE: A new way to tow a 5’er!

I promise you there is no chance this guy hooked up the brakes on the pickup bed/trailer. Probably not on the 5er either. Having them both operational would require two brake controllers. He probably didn't do it but if I were designing this system I would put a hydraulic surge brake actuator on the first trailer and just use the standard hydraulic brakes.

RE: How does GCVWR affect stopping if you have trailer brakes?

The brakes on the vehicle help stop the trailer and this is designed into the vehicle. That's why trucks have such huge brakes for their size. Notice the brakes on trucks have gotten bigger over the years? Not because the trucks themselves are that much heavier, it's because they can tow much more than they used to. The more weight you add to a given setup, the longer the stopping distance. I have upgraded brakes on my truck and it stops the whole 17K# load faster. BTW, I have seen both Ford and GM write about this very subject and they make it clear that the trucks are part of the formula and have a major impact on stopping the trailer. So yes, it is clearly part of the certification or more accurately, it's part of the design criteria. The big reason that trucks have large brakes for their size is that empty tow vehicles generally have a high power to weight ratio, enabling people to drive faster with or without a trailer. The faster you drive the more brakes you need. You may notice that most performance cars have big brakes even though they have zero rated tow capacity. The big brakes do help stop trailers as an added benefit but the problem with that is then your braking ability is limited to the traction that the truck has. As your trailer get heavier that becomes a bigger and bigger issue. To stop quickly you need every tire on the ground doing all it can to help. If your trailer axles are carrying twice as much weight as the truck axles are and the trailer brakes fail you are going to take at least 3 times farther to stop, no matter how good the truck brakes are. In this case, fade resistant truck brakes will help keep the distance from being more than 3 times as far. In general, a 7K axle on a trailer does not need to be as large as the brakes on a 7k truck axle because you physically can't do repetitive stops as frequently due to the mass of the trailer slowing your acceleration. The brakes have longer to cool down during the slower acceleration and when you do use them the power produced by engine is split between more brakes. Good trailer brakes also help prevent jacknife situations.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Toyota. With a highly trained 20 year CHP officer at the wheel. And this is with a weenie Toyota with what? 150HP? 200HP? Let alone a very high torque electric motor. I would ask you to talk to him about this but he died along with his whole family after this Toyota "overpowered the brake system." Want more? I have more but I'm a little busy tonight.Granted it is an unfortunate outcome. Although I did not see the results of the investigation that explained how both the throttle stuck open and the brakes failed. Could be suicide for all I know. Happens although not usually in this fashion. I guess that shifting into neutral and turning the ignition off failed too. Something really is fishy about this story.

RE: F350 Super Duty vs 3500 Denali vs The Ike Pulling 30k lbs

4X, how much do you think these 10 speeds help with the Diesel engines compared to their previous 6 speeds? Lets say the Ford with todays HP/TQ with 6 speed would it do as well as the 10 speed or??? I would like to see a Dyno test showing hp to the rear tires while showing speeds from 15mph to 75mph with the two transmissions. I expect that the 10 speed would have much smaller dips at shift points and therefore higher average hp to the ground. But I hate to assume anything.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Just a question: If the $35,000 model was so unpopular and nobody wanted a "plain jane Tesla", why did reservations go through the roof when the $35,000 model 3 was announced? "...in March 2016, Tesla promised that it would start at $35,000. It built up a preorder list of over 400,000 customers based, at least in part, on that promise." So nobody wanted a "plain jane Tesla", huh? Just trying to keep the truth out there. If Ford opened up reservations for next years F150 would you assume that everyone wanted an XL? Since you are not going to buy a Tesla anyway and you probably don't know anyone that is concerned about it why do you concern yourself with it?

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Say what you want, BUT..... IIRC, when the 3 was introduced, the 35K price point was the big deal. When you fail to bring to market the main selling point for 3 years, after taking thousands of deposits....... You failed. plain and simple. Actually it is. But just like nobody wants a Ford truck in XL trim nobody seems to want the plain Jain Tesla so it is off menu. How to buy a Model 3 for $35,000 And the main selling point is value. In other words building a vehicle with enough features at a price that enough people are willing to pay for. Sometimes it takes a while to find that balance. If you take a look at truck prices since Tesla announced a $35,000 price it is easy to see that average truck have gone way up along with the content and are still climbing. In the just released TFL video comparing a 3500 Silverado with the F350 they complain about the lack of features on the Silverado even though it is the nicest truck that Chevy has ever made. Adjusting your product to meet customer demand is not a sin, it is smart business.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

"When the Model 3 was finally unveiled 10 years later, in March 2016, Tesla promised that it would start at $35,000." Didn't happen. Geeze, are you dense, or just being obtuse on purpose? IT DID NOT HAPPEN! It was promised to be priced at $35,000 when the model debuted. IT DID NOT HAPPEN! You could not buy one for $35,000 until 3 years later.None of the previous vehicle launches went that way. Always started with a fully optioned founders edition. I think you had a bit of wishful thinking or a bit naive. Eventually Tesla was to have a starting price of $35,000 NOT start production with the $35,000 model. Anyway we will just have to disagree on this. The real question is have your ordered yours yet? And sorry for the wait. Has been available about a year now IIRC.Like I said: Waaaaaay out of my price range. No way for me to ever justify that much money for a car. I had to grit my teeth to pay $9500 for my last car. $35,000 would give me a heart attack. So you have been making a huge fuss out of something that not only nobody else cares about but you yourself really don't care about either. Sounds like you just like to hear yourself fuss.
