Driving uphill is at first glance not very compatible with energy savings. Yet there is little tricks to know.
YOU CAN SAVE YOUR ENGINE WHILE DRIVING UPHILL
This is true, driving in very narrow roads, close curves, brake and re-accelerate endlessly to gain some power does not help us to save fuel. Besides the release of exhaust gases that are compounded after each acceleration. So how to save money along the hill?
Firstly, priority should be given to situations of inertia. What does that mean? Just leverage the weight of the vehicle, once launched on a flat road to make the most of the momentum of the car (its kinetic energy in a way) then to go uphill. How is it done? Accelerate slightly and regularly before the hill, and maintain acceleration at the start and half way during the climb.
As the passage of a low hill can be negotiated without problem with this piece of advice, however, to climb the “Tourmalet” can not be done without additional actions. Indeed, the hill is too long/high, you come to a loss of power when the vehicle’s inertia is no longer sufficient. Must be compensated. The rule is to never be in a situation of “pedal to the floor.” This is where the fuel intake is the most important, regardless of your speed. So you have to keep downgrade enough “recovery” and keep your accelerator pedal slightly depressed.
When at the TOP, RESIST THE URGE TO ACCELERATE.
Firstly, because there is no reason, the slope will make the car accelerate naturally.
Then, because there is no better way to save fuel as the descent. Use engine braking allows for instant consumption 0 liters per 100 km. This applies to almost all vehicles equipped with direct injection system except perhaps the oldest still have carburetors.
Finally, because a speed mastered downhill will save your tires and brakes, since you will not have to stop too violently.
Good road to all & happy driving!
