America's Cars Are Suddenly Getting Faster and More Efficient (bloomberg.com) 483

Posted by msmash from the need-for-speed dept.
Kyle Stock and David Ingold, writing for Bloomberg: Sometime in the next couple of months, the Dodge Challenger SRT Demon and its 808 horsepower will show up in dealership windows like some kind of tiny, red, tire-melting factory. Yes, 808 horsepower. There's no typo. Last year, U.S. drivers on the hunt for more than 600 horsepower had 18 models to choose from, including a Cadillac sedan that looks more swanky than angry. Meanwhile, even boring commuter sedans are posting power specifications that would have been unheard of during the Ford Administration. The horses in the auto industry are running free. We crunched four decades of data from the Environmental Protection Agency's emission tests and arrived at a simple conclusion: All of the cars these days are fast and furious -- even the trucks. If a 1976 driver were to somehow get his hands on a car from 2017, he'd be at grave risk of whiplash. Since those days, horsepower in the U.S. has almost doubled, with the median model climbing from 145 to 283 stallions. Not surprisingly, the entire U.S. fleet grew more game for a drag-race: The median time it took for a vehicle to go from 0 to 60 miles per hour was halved, from almost 14 seconds to seven.

  • Essentially you can either use the same improvements to make the cars more efficient in terms of gas usage or you can make them have more total horsepower. Unfortunately, many of the people buying cars prefer the second, so this is what we end up with. The long-term results of this are going to be not at all good.

          Would agree in general, but the struggle is that a modern car that can accelerate more quickly then older cars are prevalent across the spectrum -- i.e. technology has made smaller cars/smaller engines much more performant. In addition, it is much harder to make the argument that a car next to you capable of accelerating faster then a typical car from the 70's is causing you direct harm, unlike second hand smoke.

        Bad choices are those that hurt everyone for the gain of a few, and driving more fuel efficient vehicles is necessary for the long term success of the country in terms of keeping us out of expensive wars, having us destroy our own environment to pump more oil, reducing emissions and just to keep prices down to avoid gas becoming too expensive in a country where not being able to drive may lock you out of employment. When it comes to adding more HP to a car, and the public flocking to those horses rather than fuel efficient vehicles, then it may come time to make a law to stop it (or I'd advocate, make it expensive but not illegal). However, since even here in Texas those cars still represent the vast minority, maybe there's no need for someone to step in.

      Same reason people buy ludicrously expensive Rolex watches. To show off. It's conspicuous consumption in most cases. Muscle cars however do have one quasi-practical aspect depending on your perspective. They are good at straight line acceleration which is really the only kind of fun thing you can do on normal roads. Basically they do a burnout between stoplights.

    You notice these cars are not Fuel Hogs. They are actually using the energy that used to dump into the squishy torque converter. The cars are actually streamlined unlike the box cars of the 80's. They are burning less energy by running a larger percentage of recirculated exhaust gases through the engine when at idle and power is not needed. This doesn't even take into account electric flywheel assist and stop start technology where the vehicles engine is shut off at lights. When the power goes to the road you go quicker. I'd wager the cars are lighter too aluminum engine blocks are the norm now.

    The Challenger is a lot of things, but unless you're comparing it to an aircraft carrier I don't think "tiny" is a good adjective for it. Part of why it needs an 808 HP engine is because it weighs ~400 pounds more than the Ford Mustang that it competes against in the same class.

    Very bad choice using 1976 as the comparison date. For a better clue tou need to go back before 1971.

    1976 was at the end of a notorious low-point in power thanks to the US auto manufacturers responding to new emissions regulations and the 1973 oil crisis:

    Example of just Corvettes:
    1969: least powerful (base): 300HP Most powerful (LS7) 460HP

    What will happen with american built high power cars when - perhaps even by committing a crime - being pushed to the max speed? (breaking apart?)

    Because its no such big deal to put much power into a car, the problem of aerodynamic lifting forces come into play interacting with shock absorbers.

    The space between the street and your cars under-floor at high speed can make out the difference between driving and flying,
    because more distance to the road = more air being pushed under the car = lifting your car off the ground.

    So a bump on the road can send you flying, and I don't think american highways are designed for speed like the german "Autobahn".

    Great. Muscle cars are back, and they're high-tech. Meanwhile, we haven't been educatiing, training, or testing drivers properly for at least 20 or 30 years, which means we have an entire generation on the roads who really aren't competent, which has sparked an entire legion of idiots who claim that 'humans aren't capable of operating a motor vehicle competently, therefore we need to ban them from driving and have self-driving cars instead!' which of course is nonsensical bullshit. So we'll have under-educated, under-trained, inadequately-tested drivers behind the wheel of vehicles as powerful as a goddamned Formula-1 racecar, who will wrap it around trees and telephone poles and kill more people, which will just strengthen the strawman argument in favor of taking away everyones' driving privilege and making us risk our lives riding in shitty so-called 'self driving cars' that are not anywhere NEAR up to the task.

    Bull-fucking-SHIT.

    What we REALLY need is reforms in driver education and trianing (read as: fund highschool driver-ed and driver-training programs again!) and reforms in how the DMV tests new drivers.

    Oh and while we're at it: Educate and train new drivers to recognize and properly, safely deal with cyclists on public roads. There should never ever again be an excuse of "I didn't see him" when someone hits a cyclist.

      Maybe, if that education and training goes both ways. Where I live, cyclists regularly swerve in and out of lanes, cut across multiple lanes of traffic without warning, run red lights, and generally act like self-entitled asses. I've more than once had to lock up my brakes to avoid hitting one of these idiots.

    America's Cars Are Suddenly Getting Faster and More Efficient

    With a title that notes cars getting "faster" and "more efficient", it would be nice if the, fairly long, summary actually mentioned both things rather than just the faster part -- especially as the latter is more important. Seriously, I can only go so fast so quickly, but efficiency helps out all the time.

    As for "suddenly," the only time comparison in TFS is between 1976 and 2017:

    If a 1976 driver were to somehow get his hands on a car from 2017, he'd be at grave risk of whiplash.

    We, apparently, have different definitions of the word "suddenly".

    To everyone thinking people are suddenly going to be blasting around in the Dodge Demon, it's quite obviously a car designed to be capable of fast drag strip times while also being street legal. And yes, I'm sure some dunce will wrap one around a telephone pole, but they are not going to be hugely prolific cars.

    And as someone who is involved in both drag racing and oval dirt track racing, I prefer a car with good mileage, only modest power, and very good handling for a daily driver.

    There ARE pretty high performance cars that get mileage I never even believed would be possibly, usually to displacement on demand technologies where cylinders are literally shut off when not needed. This was tried many many years ago with little success, but now they have the ability to actually collapse the lifters and keep the cylinder sealed so pumping losses drop to a minimum and you can realize the full benefit.

    And as for the "squishy" torque converter, that was solved years ago with a lock-up converter. The converter only acts as a converter during necessary transitional states. The rest of the time, a clutch inside it locks up and turns it into a direct drive mechanism, removing most of the fluid losses inside.

    One of the big gains to thermodynamic efficiency can be had with compression ratio increases, which has been seen. Historically, due to only crude control over the combustion process (carburetor, mechanical/vacuum based ignition timing curves), an increase in compression ratio pretty much necessitated increased fuel octane. Now this isn't as true, given the much more precise control over combustion with direct cylinder injection and individual coil per spark plug . So compression ratio can be increased with advanced control to prevent getting into knock, then detonation, the pre-ignition, then ultimate failure.

    EGR is good for efficiency in some cases, but is a horsepower killer. Racing engines intentionally keep the exhaust valve and intake valve open simultaneously (known as overlap) to pull fresh air and fuel through the cylinder on every cycle to "scavenge" out and clean all combustion products out from the previousl cycle. The downside is that some raw fuel is discharged out the exhaust.


    Bottom line is we have cars now with horsepower ranges from a 4 cylinder that would have been tough at times with an 8 cylinder engine and getting 2x or 3x the mileage (sometimes even more!). We are on the right track. High performance cars have been ingrained in auto industry DNA for a long time.
