I was guessing I was hoping for something that wasn't going to happen and your right at least I don't spend much on fuel! On the Highway the few times I have made the Journey from the Island to Houston it's done pretty decent 25-29. I only live about 1.5 miles from work and most of the time I can catch every light besides two because all of them on the one way are set for 30mph, she is an auto so no help there and I did notice today unlike the Sonata if you tried to shift into a higher gear it wouldn't even try it would just keep you in the lower. The xB it will show your in 4th gear at 15mph when it's in 1st or 2nd and then it will auto up shift like normal when it hits it's set speed
Thanks for the ideals
Happy Thanksgiving, to you too!
I have a first generation AT, like DubeexB, but I lurk in here hoping to pick up tips.
One technique at lower speeds is to coast. Ideally, you'd conserve momentum and use your brakes as little as possible. This is partially why it makes sense to air up your tires, as DubeexB suggests. I've found the most effective way to increase city mpg is to coast in neutral and to eliminate idling (at stoplights). You can also coast in D, where DFCO (deceleration fuel cut off) kicks in- this is when the engine isn't burning any fuel. DFCO on my xB classic kicks in at 1500 rpms or higher. I'm not sure where it kicks in on your 2nd generation xB, but I'm sure someone here would know.
Due to the aerodynamics of the xB, coasting at highway speeds isn't as effective because you're fighting the wind, so that's an advantage of your local routes. Also get up to speed quickly, assuming you won't be using your brakes anytime soon. You don't want to get up to speed quickly, only to slam on the brakes at the next light.
Finally, study your lights. Not only will this allow you to catch more green lights, this will also allow you to turn off your engine when stopped (and start the engine without holding up traffic behind you). Some newer cars shut off their engine automatically when the car is stopped because it's one of the biggest fuel wasters.
