gas price thread

As much as I despise the auto industry for its refusal to give up planned obsolescence and deliberately building inefficient/overpriced/maintenance-hungry products, banning cars is a stupid idea.

What needs to change is how cars are designed and built. Design by committee needs to be replaced by engineers with a vision or goal in mind. Form should follow function, not the other way around. The air that is disturbed by a car moving down the road doesn't care what is in the car, what the car is composed of, or what function the car is being used for. Everything on the mass market is designed totally backwards if the goal is having an inexpensive, efficient, practical machine, and the vast majority of new vehicle buyers don't know any better nor care. Even something as useless as a corporation's brand-identity is emphasized in a car's design to the detriment of criteria such as efficiency, reliability, cost, performance, and other factors(just note the massive grilles on modern BMWs or Lexuses as an example).

I'd like to see everything collapse so government and various entrenched companies can finally be out of the way, and we can see a large number of small companies take its place, which may soon become technologically viable at scale as 3D printing takes off. Unless government comes in and regulates/bans it at the behest of lobbyists after the day comes. Then we could see some actual experimentation among real-world products, instead of the same old cookie-cutter designs intentionally made to part people with their money and waste resources.

There is no technical reason our cars can't get nearly double the current efficiency using conventional production methods, without much in the way of compromising anything or increasing cost. Performance in fact would go up. But a lot of rich executives' sacred cows would get gored in the process and the industry would have to actually start trying new things on a regular basis instead of being so overly conservative that they're scared to do something that concept designers had proposed and even successfully demonstrated as technically viable driven-on-road one-off cars many decades ago. And having seen the advancements in electric vehicle tech play out in the 1990s, it is clear to me that the only thing that will make the mainstream automakers change is if they have no choice. If we didn't have Tesla, odds are great that none of the major automakers would be making any EVs at all today, as the technology was viable for well more than a decade before Tesla even existed. It may not have been as good, but it was "good enough" that 150-200 mile range sedans were demonstrated in real-world conditions, and repeated studies within the industry itself suggested they could have been affordable in mass production AND that consumers would buy them if they were competitively priced with ICE cars. Yet the foot dragging continued, for well over a decade.

Tesla kinda sorta got halfway towards building a car emphasizing function leading form with its Model S and Model 3, but even in both of those there is massive room for improvement due to all sorts of design concessions that have more to do with style than substance. And none of the other automakers have come close to the efficiency of Tesla's platforms with any mass produced offerings, inspite of demonstrating they were more than capable of offering cars even more efficient than Tesla's platforms 50+ years ago.

And unlike the claims oft repeated by industry execs along the lines of "no one will buy the world's most aerodynamic car", Tesla's platforms are selling so fast that Tesla can't keep up with demand. Their cars have roughly two-thirds the drag of what is typical, yet they still look quite conventional, and thus were not dedicated streamliners from the start. No automaker has ever dared to try to sell the public a dedicated streamliner, yet wants to claim no one will ever buy one. I beg to differ, especially when you consider it could have opened the door to 40+ mpg full-sized V8 musclecars during the 70s fuel crisis using antiquated carbeurated engines, while consumers were flocking to a 14 mpg Ford Pinto that was already widely considered ugly as a replacement for their 10 mpg V8 lump of Detroit iron.
 
Lots need to change
They are not known for efficiency or smarts by any means once so ever.
Even the simplest of tasks, they mess up on and go over budget. I dont mind going over budget, its easy to rip off the government, but at least have the shit work half decently then be a p.o.s.
 
If the government is ineffective at that change, then it's our job to see fit that that change happens.

Luckily for us, this forum is filled with the kind of talent and genius that can make such a change happen. How cool. :mrgreen:

The real world is a major set of compromises..
Many aerodynamic cars have been developed and marketed over the years (Citroen DS , Prius, etc) , but they never were big sellers.
Some of the most popular (practical ) vehicles sold are the dual cab trucks and SUVs, which would be difficult to make very aero simply because of their size and essential function ( carry capacity and loading access).
Not everyone can live with a velomobile !
 
Actually, it's possible to get pickup trucks into the 0.2 Cd range and SUVs/CUVs into the upper or even mid 0.1X region.

The 2005 Mercedes Bionic has the sort of shape an SUV/CUV designed with aero in mind could have(albeit, this vehicle is a compact car, but an SUV type vehicle could be made out of a scaled up version of it and modified accordingly).

There is no shortage of universities and other institutions, and in some cases, even hobbyists, that have greatly reduced the drag of pickup trucks and SUVs without entailing the sort of compromises that would inhibit the vehicle's functionality as an SUV or pickup truck. Even in the early 2000s, there were modified Ford Expeditions approaching 35 mpg thanks largely to aerodynamic work and gearing changes, using the stock oversized gas-guzzling engines. Something very close to the shapes we see on the road today were every bit as possible to make 50 years ago as they are today and would have presented a significant improvement in economy versus the bricks we had back then, and the shapes we see today are far from optimized for the purpose of efficiency. The concept cars I listed in an earlier post within this topic are proof of it.

Aerodynamacists started to get a decent idea of what to do 100 years ago. The Dymaxion car is said to have a 0.25 Cd, which was not matched in a production car sold in the U.S. until the Honda Insight came out. The 1935 Tatra T77A, a full size land yacht of a car, had a drag coefficient comparable to the current Tesla Model 3, about 0.21. Today's Toyota Prius has a Cd that is a match for the 1949 Hotchkiss Gregoire. The average modern sedan has just now caught up to the 100 year old Rumpler Trophenwagen in terms of drag, and they look absolutely nothing alike(keep this in mind when someone tells you modern cars look so similar to each other because of aerodynamics, as it's total BS. They look similar because of decisions made years ago by marketing departments and a refusal on part of the industry to try different things). All of these old cars didn't have the benefit of CAD or even CFD analysis that modern automobiles do, let alone modern knowledge of aerodynamics, as it would be greatly more than half a century later before something as fundamental to CFD as the Navier-Stokes equations were solved. None of this is rocket science.

Instead of seeing dramatic improvements in vehicle efficiency as was possible, we got incremental change so that no one's apple cart got turned over, when had we had major changes to improve vehicle efficiency decades ago, it would have dramatically changed today's landscape regarding energy use and climate change, for the better. Even to this day, we still only see incremental changes. The most major change allowed has been electric drive systems, which is thankfully major and not incremental, and only then because of Tesla entering the market and disrupting everything, which is forcing the rest of the industry to attempt to catch up, lest they die out. Remember how "no one wants electric cars" as was the propaganda over the last few decades. With primitive NiFe batteries and an attention to streamlining, we could have had 150 miles range in the 1980s, and with NiMH batteries, 250 miles range in the 1990s.

The real world is run by greedy pieces of shit and their sycophants, whose uninterrupted maximization of wealth/power is never up for compromise, no matter the consequences. There is no level of violence they won't resort to in order to maintain it, either. The world would be a better place without them.

While that may be true, it is also true that the real world is full of "greedy pieces of shit" (or substitute your own derogatory term for people who don't want aerodynamic and efficient cars.)

If very aerodynamic cars were in demand, the original Honda Insight would have sold hundreds of thousands. They didn't. Hypermilers were getting 80mpg out of them. But it wasn't very popular, so it was replaced by a new, less aerodynamic version.

Nowadays the Prius has hit .24 Cd, which is great. (I have one.) But from a marketing perspective, it is about the smallest/most aerodynamic vehicle that's been popular - and even then, it's never even hit a quarter million in sales. Compare that to the F150 that sells three times that regularly.

So we have the technology but not the demand. How do you deal with that?

The Honda Insight was a 2-seater. The market for 2-seaters is already greatly limited, composed mostly of sports cars and exotics. Its closest competition at the time was doing 0-60 mph ~6 seconds and reaching 140+ mph, and its closest competition was rear wheel drive and cost almost twice as much while greatly outselling it.

I bet if they'd have made it rear drive or AWD, added a turbo, upgraded the electric drive with more power, and made it more performance-oriented, they'd have sold more of them, even at double the cost, and with hardly any hit to fuel economy. It was such a deliciously light platform that every additional horsepower would have counted greatly more than its closest competition.

John Wayland, builder of what was once the world's fastest street legal EV conversion the "White Zombie" Datsun 1200, once wrote an article about a Honda Insight he drove, that the owner modified with a turbo charger. Fuel economy stayed the same when driven normally, 0-60 mph dropped to about 7 seconds when the accelerator was floored, the front wheel drive and the associated traction issues imposed being the limiting factor to its performance. A more powerful electric drivetrain could have accomplished the same thing and then some without stressing the engine.

Nowadays the Prius has hit .24 Cd, which is great. (I have one.) But from a marketing perspective, it is about the smallest/most aerodynamic vehicle that's been popular - and even then, it's never even hit a quarter million in sales. Compare that to the F150 that sells three times that regularly.

Compare that to the Tesla Model 3 which is even more aerodynamic. The 3 has been selling about 150k units a year, +/- a few 10k depending upon supply line disruptions and parts availability limiting production. It's outselling the Prius by a ratio of 3:1. Cd of the Model 3 is 0.21-.23 depending on what wind tunnel it was tested at. Tesla can't sell enough to meet demand.

F150 buyers generally don't care what Cd their truck has, but it could be improved greatly without hurting its utility as a truck. For the electric version, it would make too much sense for Ford to even bother.

So we have the technology but not the demand. How do you deal with that?

That's always been the excuse, and it's not true.

Case in point, the 1930s era Chrysler Airflow. The execs blamed its(relatively) aerodynamic body on the lack of sales. It had a Cd of 0.51 according to Alex Tremulis. According to aerodynamicist Phil Knox, John Tjaarda had pitched a lower drag Chrysler body to Walter Chrysler, in the wake of Airflow. Walter said, "Forget it, streamlining's dead, no one will ever buy it. All we want are conventional silhouettes." Not acknowledged is that the 1937 Lincoln Zephyr had a Cd of 0.47, and was a relative success for its time and place.

The Airflow wasn't even aerodynamic. It had the appearance of being such. Yet low-drag was blamed for its failure. The Airflow prototypes were a lot more slippery, but didn't look radically different from the production versions.

Modern cars have most of the styling cues to mimic an extremely slippery streamliner, without the actual streamlining to go along with it. Very subtle changes, almost unnoticeable to the naked eye, to a modern car, can radically reduce its drag. But why would the auto industry go through the effort to do that to improve fuel economy 50% and greatly increase potential top speed when they decide to go through the trouble to place massive drag-inducing predator grilles on your new Lexus and fake vents all over your new Toyota Supra to show off the brand's "distinctive" design language?
 
Its to sell cars.
Why did the idiot at the pizza store buy a new Chevrolet Traverse? Waste of effort and money, but he was approved for the loan and he likes the looks to move his family around. He doesnt know the major mistakes of that vehicle, most buy vehicles in that manner.

I bet that p.o.s. Chevy will have paint problems within 3-5yrs, the emblem will start to fade within 2yrs.
If he babies it, it should last 25 yrs if the timing chain water pump doesnt murder the engine.
Other vehicles require a few hrs of work just to get to simple components, alternator is common, injectors, turbos.
Its all cha-ching for the dealership.

Even the great 3.8L 3800 series engine has some problems, like plastic engine components that break easy that is easy to fix and a couple other very minor issues. That great engine should still be available but its not because it lasts to long, stopped producing them years ago. The problem with those cars with that engine is other things fail, brake lines for example, paint is common for domestic vehicles.

Most likely because the oil industry's have their people on the boards of directors of the major car companies to mitigate things like high fuel efficiency. Or at least in the past they have had them on the boards of directors. However things are changing now and going in a direction where I can see the mountains 20 miles away from the local hill tops. When I was a kid we couldn't see 1/4 mile away due to smog. My eyes were permanently bloodshot. My lungs would burn on the smoggiest days. So would everybody else's' around here. Despite the ebb and flow or politics and auto advancment, emission problems have gotten better in the places where we fight for clean air.

One of my hobbies is getting a good look at those dual cab trucks and SUVs, just to see if they are really being used for their intended purpose (as you state carry capacity and loading access). Hint: They aren't.
 
Hey does anybody remember a few years back, the former POTUS rolled back the upcoming stricter fuel economy regulations? And several auto manufacturers complained, said they didn't want them rolled back, preferring to comply with the stricter fuel economy goals? What was up with that??? :?
 
Because they spent money already, and probably get kickbacks, rebates, incentives what have you. Have deals and contracts already in place, already made investments. Planning man.
What you think big companies just wing it and can move on a swivel instantly :lol:

I've had conversations with the people who own cars with this "use case".

Point out that they could save incredible amounts of cash by driving a small car daily and renting a truck for the couple times a year they need to move something, and their answer is usually 'yeah well..'. These people have no comeback for that. So..... why do they own a fuel waster 9000? i never get a good answer.

I'm still trying to get one of those people in my circle to experience the joy of hypermiling a small car. I think people don't understand it until they try it. There is a certain kind of joy that comes out it that isn't well understood. Once you've done a 2000 mile roadtrip for $100, it's pretty easy to understand that joy though.

This is the fuel economy i see daily with some very light hypermiling. Feels like you're driving a perpetual motion machine compared to a truck.

The USA loves the automobile. Most here do not see it as a tool. It's a statement and a waste of money for most here. In south Texas most are brain washed to needing a Truck or SUV. Had to convince my mother that she did not need to own a truck. You can rent a truck or have things delivered. Over 4 years now don't think she gives it a second thought now and will ask her. Trucks/SUV's are so tall older people have a time just getting in.

Here is a thought; Thinking about the fuel cost in the UK vs US, seems that the cost per mile is not that different. Fuel is cheaper here in the US but the autos use more fuel?

Agreed that we can not move away from our traditions over night but it has been 50 yrs now. Chev is making a E-Truck that goes 400 miles on a charge!

Try to stay off the freeways, to dangerous. They try to drive 80-90 mph. Take the side roads my car does not use gas at the stop lights.

Embarrassing them works :lol: I've got a Unimog 404 I use for woodland clearing, chunky great tyres and a damn great winch on the front, park it beside one of the things and they're never seen again (still fairly easy to find 404's at a decent price in Europe). Totally impractical to convert to electric as-is, the drivetrain swallows up about 30% of the power when cold but big hub motors would work ok, surprisingly nice to drive on the road but it's always going to be an agricultural implement at heart.

Even diesel guys hate coal rollers now; to do it you have to leave power and torque on the table, making your engine inefficient. I've heard em' called things I think would get me banned here.

Don't do this dude. Life is honestly, too chaotic and unpredictable to ever claim that X person should never have the big boy truck. And ya'll need to understand that, because that goofy and stupid "But what if" chaotic problem of life is why people in the USA buy SUVs and Trucks in the first place. This is the nation of no safety nets or second chances, little unemployment, and a bitter workforce that preens it's chest over how overworked it is- of course they would all want a single "do everything" vehicle, when they feel like it has to be able to "do everything" just in case something bad happens.

I mean it's cool, but unless it passes crash safety we ain't seeing it. Besides, it's also gonna have to have triple-digit power and range numbers to ever even be sellable in the US- it's just what the market demands.

Funny enough, the biggest factor changing trucks is their size- they're so big now they can barely fit into NHSTA-standardized parking lots.
