If you gently slow to 30 MPH as soon as you see the stale red light, the chances of it turning green before you get to it go up. So slowing down gently increases the odds that it will turn green before you get to it.
I will make one suggestion. The more work the brakes do, whether it is a lot over a short time or a little over a longer time, the more energy is lost and the lower overall efficiency and lower mileage.
Braking gently has to be a positive for tire wear too. Hit the brakes and slow down half a block away and you may not have to stop at all since the light may change by the time you get to it. If both cars are coming to a stop sign, not a light, and both get off the gas at the same time, the hard braker has a time advantage.
The hard braker will reach the stop sign first. Through a series of stops the hard breaker will have a higher average speed with the same fuel consumption.
The hard braker can then reduce his average speed by using less throttle. How is hard braking less fuel efficient than gradual braking? Oops, I meant to put this in the General Discussion section. Every time the driver ahead taps his brakes, you have to slow down even more than he did.
That's because you can't react immediately so you have to slow even more because you're slowing down later.
Then you accelerate again to get back up to speed and resume your bumper-buzzing routine. Hang back and you'll be safer - plus you'll be able to drive more smoothly and use less fuel. A good rule of thumb is to allow two seconds of space between your car and the one ahead. You can figure that out by counting off two seconds after the car in front of you passes an obvious landmark like an overpass.
You've probably heard that it takes more gas to restart a car than to let it run. Maybe that used to be true, but it isn't anymore. With modern fuel-injection engines, it takes very little extra gas to restart a car once it's warmed up. Idling, meanwhile, burns about a half-mile worth of gas every minute, according to the California Energy Commission. That's why hybrid cars shut down their gasoline engines whenever they stop, even for a moment.
Now you don't want to shut your engine down for every little stop in your regular, non-hybrid car - it's not designed for that - but if you're waiting for someone to run in and out of a convenience store, turn off the engine. And don't go through the drive-through at fast food restaurants.
You're already paying enough for the oil in those chicken nuggets. Bonus tip: Don't idle your engine to let it warm up before driving. It does your engine no good and it wastes gas. Instead, start driving right away, but drive gently until the engine is warm. For really short trips, take advantage of the opportunity to get some exercise.
Try walking to the store instead of driving. You can save gas and burn a few calories instead. If you can't hoof it, save up your errands. A lot of short hops that let the engine cool down at home between trips can use twice as much gas as starting the car once and making a big sweep to all your stops, according to the U. It should also never be used in a situation where you need to step on the brakes to avoid an accident.
To put it simply, you want to take it easy on your brakes in order to not only have a set of brakes that will last you a decent amount of time, but to also up your fuel efficiency. The best way to avoid using fuel when braking is to take it slow.
Remember, we want to avoid slamming on the brakes and accelerating over and over again. A heavy foot while driving is never a good option, for brakes or accelerating! Now, slowing down before you reach a stop light or engine braking before a stop light is a good option for fuel efficiency. But when it comes to stop signs, things get a bit more tricky. For stop signs, you have to stop completely.
