click and clack, the tappet bros. on the issue of fuel economy

I read their column about a month ago, and in it, someone had asked why fuel economy hasn't gone up too much over the past 20 years. Tom and Ray said that it was because automakers have focused more on horsepower/performance than MPG's. I forget exactly how they put it. An example they used was the Honda Accord. A mid 80's Accord made about 80-

90 HP and got about 30MPG. Today's Accord gets about 35MPG but puts out 160HP, double what it put our 20 years before. And Tom and Ray pointed out that most people don't need 160HP in their car, and that most people only use about half that power. They also said that most people would probably prefer a 2006 Accord that puts out 100HP and gets 50-60mpg rather than a 160HP car getting 35 mpg. I know I would. So in effect, instead of engineering/tuning cars for MPG's, they've instead been tuned for maximum HP/performance.

Why can't automakers develop 2 lines of engines? Super efficient 80-

100hp units to go into the Taurus, Accord, Camry, Malibu, etc. and cause the cars to be able to get 50-60mpg. And then a line of perforamce engines for these cars that put out 160hp and get 30mpg. Now, if you look at cars, there isn't much difference in the performance between the base 4 bangers and the optional V6 engines. The V6 will put out maybe 20-30HP more in power, and MPG's are usually about the same in the inline 4 and the V6.

I, for one, would rather cut my gas bill in half and have a 90hp engine than have a 160hp engine.

Interesting concept, but I don't think it will sell until gas hits $5 a gallon.

Sure, the latest round of prices put a small dent into Hummer and Navigator sales, but the mid range cars are still selling and we still like to stomp on the gas to get on the expressway. I just bought a new car. Did I downsize to get better mileage? No. Within a few miles per gallon, it was not even a consideration as to what I should buy.

I'd like to see what percentages of 4 and 6 cylinder engines sell in the cars that offer both. Altima seems to be moving a fair amount of the 2.5 liter but my guess is that initial price of the vehicle is more of a consideration than horsepower. The difference is about $3000. Same with the Lucerne when I was considering them. The added $3k was more of a deterrent than the 2 mpg difference. Having driven the V8, I'd have gone that way if the initial price difference was much less.

I do know of one person that now drive 5 mph slower to get better mileage from his F150 pickup though. He is the only one that does from what I can see.

We have had similar discussions before. I am wondering, out of curiosity, do you live in city, suburbia, or country and how much do you drive per day and what do you drive now? I live in Katy, Texas (west Houston suburb) and drive 25 miles one way towards downtown to work every day (and 25 miles back) on the Katy Freeway (west I-10). On a good day it takes me 45 minutes at 05:40 and 55 minutes at 18:00. I hate to give up my 92 Grand Am - it gets 24 mpg city and 27 freeway and can still burn the tires through an intersection but it has 196k on it now. Still does not use oil between 5k changes.

I also follow VW newsgroups. Same history there of their line of vehicles. Bigger engines, more horses, mpg hasn't really changed over two decades. Dependability and VW factory maintenance contracts have though for the worse.

Also another hurdle along the way in the last 2 decades is the EPA requirements for exhaust gases.

Todays Accord is a much larger car, because that is what the American buyer prefers to buy. Honda still makes a car, the size of the eighties Accord that get 35 MPG. It is called the Civic. ;)

The Grand Marquis is still the best buy on the market today. Nothing else in the 18K to 22K range brand new even comes close. ;)

Yeah, that's what I'm saying. The difference in mpg is so negligable that it makes sense to buy the bigger car. Most every car is putting out like about 180HP and getting 25-35 mpg. If they were engineered/tuned differently, I bet a 80hp 60mpg car is very possible.

I live in a small town about an hour away from a large city. I work nearby so only drive about 10 miles per day on average. We do go on road trips a lot. I drive a 2004 Kia Sedona minivan, and the wife drives a '99 Olds 88

3800. Up until a year ago, I did have a long commute.

Thanks. I have a better understanding of your view point now. I don't disagree with it. I had pictured you as living in NYC and not owning a vehicle. Someday I would like to work less than 25 miles away - and still make decent money. Paul.

You have to remember that engineers and marketers have thought of all of these things long before this discussion. If it were that easy to get 60 to

80 mpg out of cars and still maintain any degree of usefulness, those cars would be in production. There are enough people like you who would trade every other aspect of a car in favor of mileage, to make it worth the product line.

Do you think there's a reason that those cars don't exist? Think about the trade-off's in such things as minimum horsepower requirements to be usefull as more than just a vehicle to run city blocks. Think about the need for vehicles to actually be able to maintain legal and safe speeds over hills - long hills like we find commonly in the US and which are not so uncommon in other parts of the world. Think about durability. Think about comfort. Not luxury - simple comfort. Think about safety. Crush zones and integral roll cage type construction is not the complete answer. Nor are offset front end crash tests. They only reveal part of the story.

I'm not even sure that 60-80 mph is really obtainable in practical terms, and I really don't think it is in consideration of all other facets of an automobile.

I've seen several on the freeway. Decent looking car. I'll have to check them out along with Ford Fusion.

Just like 100 mpg carbs, there are still people out there that believe in fairies...

No fairies involved. I think mpg's haven't really gone too much up because automakers have instead focused on wringing out extra horsepower. They've improved gas mileage on huge vehicles. Modern Chevy Suburbans/Tahoes get around 25mpg highway as opposed to like 10mpg 20 years ago. I can see continually improving the performance of performance cars like Mustangs, Vettes, 350zx, etc., but it'd be cool to offer a 60-70mpg regular car.

Yep, and the first Civics were getting 50+ mpg hwy.

Totally illogical. Can get double the HP from same or equivalent engine over two decades, remain within increased EPA pollutant standards. Yet, cannot increase mpg without increasing HP dramatically. In fact, don't increase mpg over two decades. Nope. Total crap. A token 30+ mpg as fantastic in new vehicles, not. Consider selling used cars to little old ladies.

Consider mass/weight vs. hp vs. mpg formula. The only thing that has really increased is hp and vehicle weight. Hp in an given engine size is directly proportional to higher mpg in a smaller engine moving the same mass/weight.

Vehicles getting 30+ mpg two decades ago could go 90-100 mph on the highway. Don't remember any of them being GM though. These vehicles approximated

2000 pounds in weight. The current makers of these vehicles are dragging their feet as well for better mpg. Their vehicle weight more/more mass. Most vehicles today exceed well over 2000 pounds. Whose fault is that Mr. SUV, or "safe" vehicle? You got what the market determined you wanted. And they were probably right. So, look in the mirror for fault Mr. SUV safe vehicle.

That is not true as best the first Civics could get was 45 MPG, I owned one. However the first Civics were midget cars, with much smaller engines as well. They were dangerous little cars that could barely get out of their own way. To get any vehicle that will attain more than 50 MPG one needs to buy a motorcycle ;)

The current Camry with a 4 cy engine, is a good example of a car that gets good mileage for a car that size, but it too can not get our of its own way. I see fully loaded tractor trailers pass them on long grades on the interstates ;)

Even a small one passenger motorcycle, that is barely capable of 65 MPH, can not attain much more than 50 MPG

Bullshit . My wife's Kaw EX250 , when driven sanely , usually exceeds 50 mpg . And that's around town , it gets better mileage on the highway , again , if driven sanely . BTW , this bike , in stock form , is capable of speeds in excess of 100 mph ...
