Replying to: psulions (May 16, 2008 8:03 am) Actually it's easy to exceed the fuel economy numbers printed on the new car price sticker. It's all in how you drive and where. It's important to remember that the EPA fuel economy numbers are the result of testing in a lab. Not driving the car in real world conditions. Thus vehicle aerodynamics are left out of the equation. When actually _driving the car_ the shape and coefficient of drag play a major role. Then we have the styling and overall "looks" of a car are which are quite deceiving. A perfect example of this is my 2008 Yaris 2 door hatchback. Most people will agree that the big bulbous front end, results in a lot of drag. You'd be wrong, by a wide margin. Most people looking at a low, sleek tapered nose, like on the front of my very aerodynamic Mercedes AMG SL 65 Roadster would result in a lot less drag than the Yaris. They'd be wrong. Here are the true numbers (lower is better) .28 CD for 2008 Yaris 2dr Hatchback (all for the low low price of $14,800) .30 CD for 2008 MBZ SL 65 AMG (all for the not so low price of $192,000) Now, obviously I did not buy the Mercedes for it's fuel economy, I'm simply using it as an example of how well Toyota has a handle on the aerodynamics of it's cars. Thus providing every opportunity for the owners to obtain some very good results in the mileage department.....

Timing red lights, coasting to a stop, installing springs in the back of your garage so you can capture the wasted energy of parking your car at night. (good grief)

Replying to: podred (May 19, 2008 11:29 am) The ratings are not calculated at high speeds, and drag is exponential. My Honda Accord Sedan 4cyl gets the same mileage at 80mpg as my Yaris Sedan - and it weighs a third more. Yaris is blunt in front and steep in rear. Toyota blew it in this area. Regardless, I'm sure they were not concerned with the 80mph driver in this class of car. Your Mercedes is engineered to outperform the Yaris if you apply the handicap considering the difference in class. Yes, I know I could just slow down. |

Replying to: podred (May 19, 2008 11:29 am) I agree with you 100%. However, there are people that simply do not have the ability to do that.  Sad but true! Kip

Replying to: kipk (May 20, 2008 4:05 am) The intrinsic cost are often overlooked by people who are focused only on the gas gauge. Negative externalities are also ignored. There are other people on the road. Again....sure you can do it. But does it really make sense?

Replying to: psulions (May 19, 2008 4:41 pm) Timing red lights, coasting to a stop, installing springs in the back of your garage so you can capture the wasted energy of parking your car at night. Very funny.... but you must be drifting off into another land. At no time did I say that I made any modifications to the car other than to install the electronic readout, which is no different that those cars that come from the factory with trip computers. I happen to be having fun with all this, sorry to have lightened up your serious negative side. I will leave you alone to stew.....

Replying to: kipk (May 17, 2008 4:01 am) Simple really. 1) Leave for work, allowing yourself time to get there without having to ride peoples bumpers. Or weave wildly in and out of lanes. 2) Calculate the time spent driving at a reasonable speed (like the speed limit) and you will find that it's not an hour.....it's usually just a few extra minutes. 3) Learn to relax...and breathe.... you will live longer. After all, your only driving to work.....

Replying to: psulions (May 20, 2008 6:54 am) Of course there are other people on the road. If not, there would be no traffic and no need for traffic lights. As I wrote in post 346, which you choose to ignore: "Therefore I try to get the best mileage possible from whatever I'm driving. Keeping traffic conditions in mind." However I'm not going to let other drivers dictate my particular driving style. I'm not going to exceed the speed limit on local streets more than 5 mph. I'm not exceeding 65 on the free ways. On 2 lane highways, I will drive 5 mph over the posted speed limit. If I notice traffic stacking up behind me, I will pull over or speed up slightly. I don't really care that the guy behind me is not happy going 5 mph over the speed limit. I'm not going to tail gate the car ahead of me because the guy behind me wants to rush me along. I'm not going to run right up to a stop sign or red light before slamming on brakes, because that is what the guy behind me wants to do. On a 30 mile commute, all road, I will get there within 3-5 minutes of when you do. In traffic, we will get there about the same time. I will burn less fuel and be more refreshed than if I was rushing the entire time. What you consider a normal driver and what I consider a normal driver are different. I'm not a hypermiler by a long shot. But, every time I beat that EPA sticker by a good margin, I win.  If you are happy getting poor mileage, great!  Kip

Replying to: psulions (May 22, 2008 4:41 am)  ). I am pretty sure it has to do with gas prices getting close to $4.00 a gallon, and drivers realizing that speeding uses more gas than not speeding. Like most small-engined cars, I expect the best way to get high mpg out of the Yaris is to drive it moderately, keeping the revs and speeds down as much as possible. And as with any car, the more your foot is not on the gas pedal (i.e. coasting or using a very light touch), the less gas you'll use. No rocket science involved there. |
