Does driving with cruise control save gas?
Switching cruise control on means your engine will no longer be at the whim of your right foot – the inevitable varied pace, going slower then faster, is levelled out.
Fuel efficiency is driven by smooth driving so maintaining a consistent speed avoids unnecessary acceleration and braking which all burns more fuel..
Why do cars go so fast if it illegal?
The reason why cars can go so fast is because the engines we have now are a lot more efficient and powerful than say 100 years ago. … In order to have acceptable acceleration, you need a certain sized engine. It turns out that an engine that big will give you a far greater top speed than most speed limits.
Can cars go faster than the speedometer?
Although cars with high-horsepower engines can come close to the top speedometer speeds, most are limited by engine control computers. That’s because the tires can overheat and fail at higher speeds. Tires now common on mainstream cars often can’t go above 130 mph or they could fail.
Is it bad to floor your car?

What is the best speed for fuel economy?
65mphThe Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).

Do cars need to rest?
Vehicles No, Human’s Yes. As long as your vehicles is in good working condition (and you are using it within it’s operating envelope), it really does not need rest, just a constant supply of fuel. You could theoretically drive a car till it runs out of fuel to stop for a refill and immediately get on your way again.
Does driving slower save fuel?
Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.
Is driving fast bad for your car?
However, driving this way can wreck the engine, and the car. … If you go faster, your engine will use more gas or diesel per mile driven and your transmission will wear out. Also, when you go so fast it means extra stress on all the small moving parts of your engine, and that can cause it to wear out more quickly.
Is it bad for a car to go 100 mph?
However, generally, if your car is well-maintained, in good condition, 100 mph is nothing particularly out there. It’s probably not a good idea to cruise along for a 6-hour road trip at that speed if you’re driving an older car, but if it’s in good shape then pushing it temporarily shouldn’t be a problem.
