Is it better to drive slow or fast to save gas?

Is it better to drive slow or fast to save gas?

The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn’t true. Any slower, and your transmission will automatically shift to a lower gear, which requires more fuel to maintain.

Is 56 mph the most economical speed?

Generally speaking, there is no one driving speed which is optimum for fuel economy. This was due to the old fuel consumption test being run at three speeds: urban, 56mph and 75mph – and 56mph was always, unsurprisingly, the most efficient of these. Typically, cars are most efficient at 45-50mph.

Why does my truck shudder at 55 mph?

It is only when my speed drifts back and forth during the 45 – 55 mph zone that the problem is noticeable. If I am going up a hill, the shudder occurs at a lower speed, depending on how steep the grade is.

Why does my car not accelerate after 100, 000 miles?

The make, model and age of your car will also have a bearing on acceleration. Research pointed out by the New York Times in 2012 claims that cars are lasting up to 100,000 miles longer than previously thought, so there should be no reason a well maintained car can’t hold on to its acceleration with proper care.

What’s the maximum deceleration speed for hard braking?

Hard braking occurs around -0.55 g’s Productions years 1991 – 1995. Braking to a stop knots/s. Many safety experts use 15 ft/sec 2 (0.47 g’s) as the maximum deceleration that is safe for the average driver to maintain control, good to excellent tires, dry surface.

What’s the maximum deceleration you can stop at?

knots/s. Many safety experts use 15 ft/sec 2 (0.47 g’s) as the maximum deceleration that is safe for the average driver to maintain control, good to excellent tires, dry surface. A reasonably skilled driver can stop at 20 ft/sec 2 (0.62 g’s). Most production street vehicles have a maximum braking around 0.8 g’s.
