How We'll Get To 54.5 Mpg By 2025

concealment writes "At the end of August this year, the US Department of Transport's National Highway Traffic Safety Administration (NHTSA) and the US Environmental Protection Agency (EPA) announced new standards to significantly improve the fuel economy of cars and light trucks by 2025. Last week, we took a look at a range of recent engine technologies that car companies have been deploying in aid of better fuel efficiency today. But what about the cars of tomorrow, or next week? What do Detroit, or Stuttgart, or Tokyo have waiting in the wings that will get to the Obama administration's target of 54.5 miles per gallon (mpg) by 2025?"

    Spot on. I half intended to make a sarcastic post about how all we need is to get everyone to be willing to drive a plastic car with a 40 hp engine, but truly for a lot of people including me, a small (but safe) car is sufficient.

    I actually sold cars briefly. One customer who stuck in my mind was a little old lady who really wanted an 8 cylinder engine. This was about 1990. She might have settled for a 6, but a 4 was no sale, no way. Blew my mind. My own 4 cylinder car sitting in the parking lot, barely out of econo-box class, would do 120 mph. What the hell did she think she needed an 8 cylinder engine for?!? She would not be swayed. A lot of us, me included, are not so different from that old lady.

  2. Autonomous Cars by Konowl · · Score: 5, Interesting

    The answer to better mpg, traffic shaping, less accidents is - as much as I hate to say it - is autonomous cars.

    They can drive at the best measured MPG zone, they don't get distracted, they have faster response times than human drivers. They don't hit the gas pedal stopping you from merging onto the highway or changing lanes, they don't pass illegally or drive recklessly. Numerous studies have shown that traffic jams are simply caused by people following too closely.

    I don't know for sure, but I really think the next evolution of vehicle transport will be autonomous.

    Yeah, the problem is getting people to actually buy the high-mileage cars. Here's U.S. car and light truck sales data since 1931. Light trucks are a separate category under CAFE, and don't have to get as high MPG. Consequently they can be built bigger (relatively) and with more powerful engines. From 1931 to the 1970s (when CAFE was first implemented), light truck sales represented about 15%-20% of passenger vehicle sales. Since CAFE was implemented, light truck sales have climbed to over 50%.

    People in general want the big, powerful "cars" and don't care if they get crappy mileage. Forcing the manufacturers to improve mileage isn't going to change that. It makes me think CAFE is partially based on the conspiracy theory that automakers could make 100 MPG cars, but are all in cahoots with oil companies to keep mileage low. That simply isn't the case - consumers are the ones favoring low mileage cars because of the advantages they offer: extra space, extra safety, more power.

    If you want to encourage increased average vehicle mileage, this supply-side market manipulation just doesn't work that well. It needs to be done via demand-side market manipulation. Jack up fuel taxes to make gasoline more expensive. Then people will start to favor fuel economy more over size, safety, and power.

    I live in the US now, but I lived in France until a few years ago.
    The market is quite different in ways most people do not see.

    First of all, the weather condition in the US are very variating from a region to the other one. I live in ohio and we get snow about 5 month per year. That's a mid alps type of snow. Having a good traction is important. Most people will get "all seasons tires", which is fairly stupid, but that's what people do.

    Then, the road condition are different. I was reading recently that US policitians prefer opening new roads than fixing existing ones. The road are bad in the US in general compared to your average road in France. Having a car that can take bad roads is important.

    Most people will travel long distance, having a confortable car is important. You frequently hear "I'll drive there, it is only 18 hours driving away". People think whenever they buy a car, that they might travel for days in it.

    There might be issues on familly sizes as well, but I could not find good comparative data on it (beside fertility rate which does not mean too much).

    In France, half the problem of having a car is parking it. Parking is typically not an issue here. So there is less incentive for small cars.

    Importing car from the european market is difficult. European cars are more expensive to buy and to insure than american or japanese cars.
