My car does not. I get OK gas mileage. But I only drive it going to/from work. That's the times I accelerate a little more than usual.

My wife's car does. We get better mileage for 2 reasons:
1) because we usually drive it at all other times; when we're not in a hurry. We go easier on the acceleration.
2) it's a game to try and keep the fuel econ meter as low as possible.

dontuknowOH, that car would have done better with a VW engine. Probably cheaper to maintain, too. ;]

Here's how it died: At about 165K, we were driving North on Rte 138 in Milton, MA. The left rear started wobbling. I checked it, no heat or further wobbling, and continued on, hoping I could limp home.

My son asked, "Dad, if that thing broke would we fishtail?"
"No," I answered, "a fishtail is a kind of a skid. What we would have--"

and at that VERY moment that wheel broke off and went bouncing past my side mirror! Thank God, there was no oncoming traffic to meet that missile.
I continued,

"--have a controlled crash!"

So I eased that thing, dragging its left buttock, off to the side out of the way. A perfectly controlled crash.

End of story.
End of car!

traffic cop: The Previa you mentioned,could that engine be a left-over V W one after the war,air or wet cooled? My first VW drive was a 1964 air cooled 4 spd.fairly peppy in town...my weight was only about 205# then..

My last car was the pathetic Toyota Previa. Acceleration was pathetic. It had a flat, mid-engine, under-the-front-seat 4-cylinders which I think all laid out horizontally, two on each side of the crank shaft. Sucked!

We now have the Sienna (XLE Ltd, AWD). Much, much better! Not a Crown Victoria Interceptor, but it cruises well at 90 mph and I can get up to highway speeds good and fast--when I need that kind of performance.

Most of the time, I'm pretty laid back.

Every once in awhile it's fun to out accelerate a little toy car. Our freeway onramps generally let one car in each of two lanes merge onto the freeway from a signal light. My unassuming Chevy minivan has more get up & go than other cars.

the only time I do jack-rabbit accelerations is when I have to. Not all the time. Maybe 5-10%. Ceratinly not when coming off a stop sign or light.

Sounds like watching the traffic ahead is the best trick to keep moving, reducing the number of stops, and spending more gas to get your hulk moving again.

Yodudebc, that ambulance gives you good elevation--it sure helps if you can see several car lengths, or a block ahead. Now what if you were in a Karmen Gia?

I think the greatest inefficiency is lane swerving. It increase's everybody's frustration a lot, along with accident risk, and typically gains the person very little advantage.

Lots of comments about slow and steady, and they're all good.

But what if you really need to get someplace quick through city traffic? You can save fuel there, too.

My experience is as an ambulance driver 1979-1986. I found that I could often get to a destination WITHOUT lights and sirens quicker than most traffic, and quicker than if I had lights and sirens engaged.

Momentum is the key, of course. But the biggest difference between what I did and what most others did is that I was watching traffic a dozen or more cars ahead. I was then able to change lanes and be in a position to accelerate while most others were still looking at the brake lights in front of them.

Now that I've hung up my stethescope and my sphygmomonameter, I still move around relatively quickly and smoothly. I still watch traffic far ahead of me, and I usually know how stale the green light is, which allows me to take my foot off the accelerator when there is no point in pushing it. Traffic is usually spread out, enabling me to choose the best lane to occupy before it all congeals.

Oh, did I mention that I drive a standard? And a late model 4 cylinder Toyota with oomph if I need it, but never by accident.

Think about this; When driving city,then being stopped at idle,as the brake is released with an automatic. The tranny is in the lowesr gear(1st)that gear ratio provides the engine with the most torque making ability then used to put the vehicle into motion and accelerate it.

Yes 1st gear is when the driving wheels are in the Most Powerful position to handle any Inertia Loads,and the Easiest Gear for the Engine to accell against these resistive forces.

Simply saying the Engine at That Point in Time, has the Best Ability to build the most torque at the Least Amount of Go-Pedel/Fuel Usage. That time Interval is Short also becase the tranny will quickly up-shift to 2nd gear,after speed reaches 15, 20,or 30 mph. Punching down the pedel a bit to overcome Inertia is at that time done with the LEAST amount of LOAD placed on the Engine.

Once the rpms drop when 2nd gear is ingaged(felt),THAT is the time to ease off the Go Pedel for the gradual additional speeds reached.Simply ese off the pedel and make a more controlled (slower rate) of acceleration for 2nd, 3rd, 4 th. gear changes.

Why? Well those Higher gears is where the Engines Torque is straining more as the tranny keeps up-shifting for higher speeds Also More Throttle(GoPedel) is often used Fuel is used because of time interval is Longer in the higher gears(winding up rpms under heavier E..loads) = more FuelEnergy Usage $ $

Jack-Rabbit Starts are not what I'm refering to here at all. But Low gear is the short interval gearing to overcome that resistive Inertia force with the least amount of Engine Energy being strained away each time a start off/from a stop position. I do this regularly,it takes practice not to keep the pedel on down as the tranny shifts/speed & rpm comes higher.

Closing that Gap between your vehicle and the traffic ahead is the Hardest part to practice fuel savings during stop/go city driving,the brake pedel often hurts my ego every day! LOL

When traveling the shopping routes I constantly see drivers trying to save seconds of time by accell.. to close the gap ahead knowing at any second those ahead will apply the brakes.

When the GoPedel is pressed with the auto tranny in 2nd or 3rd gear to speed up vehicle even without a downshift,the torque convertor slippage consummes a greater amount of fuel energy Engine wise,(automatic tranny)Watch the RPMs go up,often only tenths of a second is gained timewise.

If you listen to vehicles with louder pipes,when they accell.. you can hear the engine using that extra fuel,while quiet exhaust never tells much,only G-force results(Quiet Zooming....) extra $$$ Gov.. donations LOL

If I'm trying to drive my Audi conservatively, I usually try NOT to accelerate hard enough to completely open the 'variable intake' runners. The fuel injectors are programmed to deliver over TWICE the amount of fuel once the intake runners are opened up.

Saving gas is great, and I try, but every once in awhile the cost of going
up an on ramp is not going to break the bank. 0-60 is not illegal. But
most of the time I can shift below 2k rpms and go 1st, 3rd, and then 5th
or 6th directly. My wife never gets to full or even half throttle and yet
her average mpg is lower than mine in the same ride. It's all about carrying
momentum through corners and anticipating slow downs and not using brakes.

Try having to hit the brakes less, which driving at moderate speeds.....that car in front of you, hitting her brakes at the slightest of things...like leaves falling from a tree....will have poor mileage and soon need a brake job.

I know most drivers stay concerned about speed being the cause of excess fuel waste,this is true Hiway,but when traveling City (15-45 mph.)where accelaration becomes the culprit of fuel waste,along with braking,to commute,this seems to be solved by simply by your right foot skills.

That improvement takes concentration,because traffic is the main controlling % of waste. Your mood,often relates to the remaining effort to save or not save fuel.

I have saved by stopping back aweebit at lights,then letting my Idle Torque start veh. motion(by simply releasing B..pedel),promply using low gear to accell to 20-30 mph.> (a short time interval),then easing back on pedel while tranny shifts upward to 2nd easying off(less throttle opening/Less E..load) going into high gear at a lower accell pace(Min.RPMs).

This technique resembles a "jackrabbit start" but isn't,because never is close to full throttle applied. Really most econo 4 cyl./automatics have a really low gearing for 1st gear cog(providing a lot of start off torque) with less E..fuel consumption to break the force of Inertia.

Staying off the brakes,helps to reclaim some energy cost from the previous burst of Go Pedel use! You know >> That last R..Foot application on the ? pedel. The FUPedel..... HAGDay

It's good to take it slow, but not TOO slow... it's true, if you take too much time getting up to speed the engine works hard for nothing. I've experienced with different driving habits for the past year and a half and now I shift at the recommended shifting points except if I intend on coasting for a while I leave it in overdrive so I barely have to touch the gas. My commute is 80 city and my all time average MPG equals the average EPA which consists of 45 city/55 highway driving.

actually, if you are trying to maximize mpg, which i think the original poster's intention, the best way is to get up your speed and then ease up. I'm not recomending testing the upper limits of your acceleration... but not crawling from the stop.
