Why does a car go faster on a steep hill?
On a steep hill, your vehicle will have a tendency to speed up. If you stay in the highest gear the car will also be able to go faster and you won’t benefit from engine braking. The combination of going faster and not engine braking means it will be both harder to stop and more stressful on your vehicle’s brakes.
What happens when you go down a steep hill?
Without revs, your engine will be resistant to turn. The lower the gear, the more resistance will be created by the engine. When going down hill, this can be beneficial for your brake pads as it reduces the strain they are put under to keep your speed under control on a steep hill.
Why does a car engine rev higher when going downhill?
Answer Wiki. If the transmission is engaged and the engine is connected to the wheels, as the wheels pick up more speed due to gravity, the engine RPM goes up during a downhill descend. Some people have a misconception that due to more RPM, the engine consumes more fuel.
What happens to your car when you go down a hill?
When you engage neutral gear, you are no longer in full control of your vehicle. Also, without any engine braking, you would be placing a lot of pressure on your car’s brakes when going downhill. When you are in gear, you can also react quicker and act accordingly to road hazards ahead.
What should you do when driving down a steep hill?
As emphasised in the first point, you should use engine braking by engaging a low gear when driving downhill. By doing that, you would be letting the engine slow your car down when going down steep hills without you applying too much pressure on the brake pedal.

When to use a lower gear when going down hills?
The system will usually prevent shifting to a lower gear range if you are going too fast and unless it is safe, so make sure you first slow down to an appropriate speed. Going down steep hills and long downgrades are probably the most common use for lower gear.
When do you shift gears to go uphill or down?
Every time you accelerate to pass another vehicle, go uphill or downhill, the appropriate gear kicks in. This is fully automatic and many drivers never give it a second thought. You can, however, still have some control over when your transmission shifts.
