At what altitude do cars stop working?
Generally speaking, you can expect a car to lose around three horsepower for every 1,000 feet you climb. That means that your car could lose around 20 percent of its horsepower if you were to drive from sea level and up a mountain like Big Bear, which has an elevation of 6,750 feet.
How much HP do you lose at altitude?
Higher Altitude Means Less Power Generally speaking, an engine loses three percent of its rated power for every 1,000 feet of altitude gained. This means you could lose as much as 20% of your vehicle’s horsepower if you drive it from sea level to Big Bear Lake (with its 6,750 elevation).
Do I need to adjust my car for high altitude?
Some engines may be a big sluggish at higher altitudes because of the lower air density and hillier driving conditions. It’s important to have your engine tuned up regularly and ready to handle some of the inherent challenges of a high-altitude environment.
Are cars slower in Colorado?
The main thing affecting your engine in Denver, CO is the lower air density. This means less compression, so all the vital components of your fuel, the nitrogen, oxygen, and argon, are being drawn into the cylinder at a lower rate than if you were closer to the coast.
How much horsepower does 5000 feet lose?
As a general rule, a naturally aspirated combustion engine will lose 3% of its power for every 1,000 ft of elevation gain. If you have 100 horsepower at sea level by the time you get to 5,000 feet of elevation your engine is making 85 horsepower. At 10,000 feet of elevation your engine will make 70 horsepower.
How much HP do you lose per 1000 feet?
Generally speaking, an engine loses three percent of its rated power for every 1,000 feet of altitude gained. This means you could lose as much as 20% of your vehicle’s horsepower if you drive it from sea level to Big Bear Lake (with its 6,750 elevation).
What are the effects of altitude on your vehicle?

Very few cars have active octane analysis whereby the timing is adjusted on the fly with fuel grade. VERY few and restricted to more expensive and/or performance oriented luxury vehicles. Else, all that will happen is if your engine starts knocking, it retards and you lose a massive amount of power, gas mileage suffers as well.
Is it safe to drive at high elevation?
According to this article from AAA, the stated reason is that most of Colorado is at high elevation, above 5000 feet (about 1500 meters), and the thinner air tends to prevent detonation.
