How Altitude Affects Your Vehicle in Colorado (And What You Can Do About It)
How Altitude Affects Your Vehicle in Colorado (And What You Can Do About It)
Living in Colorado means breathtaking views, mountain adventures, and… less oxygen. At over 6,000 feet above sea level, drivers in Colorado Springs face unique automotive challenges that lowland drivers don’t have to think twice about. Whether you're buying, maintaining, or upgrading your vehicle, understanding how elevation impacts performance can help you make smarter decisions — and avoid costly repairs.
1. Reduced Engine Power
At higher altitudes, the air is thinner — meaning there’s less oxygen available for combustion in your engine. For every 1,000 feet of elevation, your engine loses about 3% of its power. That means here in the Springs, naturally aspirated engines could be running up to 18% less efficiently than they would at sea level.
What you can do:
Look for vehicles with turbochargers or superchargers — they force more air into the engine, helping to offset the altitude’s effects. If you're already driving a non-turbo car, consider tuning, high-altitude filters, or even an oxygen sensor check to improve performance.
2. Lower Fuel Efficiency
Because your engine is working harder to maintain the same output, you may notice a drop in fuel efficiency. Your car might compensate by using more fuel, especially when climbing steep grades like those near Pikes Peak, Ute Pass, or Monarch.
What you can do:
Stay up to date on air filter changes and fuel system cleanings. Consider vehicles with adjustable drive modes that optimize fuel delivery and throttle response based on conditions.
3. Tire Pressure Fluctuations
Air expands at higher altitudes, which can cause tire pressure to rise unexpectedly — especially after a change in elevation. Overinflated tires reduce contact with the road and wear unevenly.
What you can do:
Check your tire pressure regularly, especially after road trips or heading up into the mountains. Aim to adjust pressure when the tires are cold for the most accurate reading.
4. Cooling System Strain
Thinner air also means less effective heat dissipation, putting more strain on your radiator and cooling system — especially when towing or hauling on steep grades.
What you can do:
Have your coolant levels and radiator inspected seasonally. If you’re using your truck or SUV for towing in the high country, consider upgrading to a high-capacity radiator or adding an auxiliary transmission cooler.
5. Altitude Can Impact Older Vehicles More
Vehicles built before the mid-90s with carburetors or older fuel injection systems don’t automatically adjust fuel-air ratios at elevation. This can cause rough idling, stalling, or loss of power.
What you can do:
Make sure your vehicle has been properly tuned for Colorado’s altitude. Our technicians at McCloskey Motors can perform a high-altitude inspection and make the adjustments needed to help your car perform at its best.

FAQs
Q: Do I need to change my car’s air filter more often at altitude?
Yes! Dust and thin air can clog filters faster, especially if you drive off-road or through construction zones.
Q: Is it safe to tow in high elevations?
It can be — but you’ll need to pay extra attention to cooling, power loss, and brake wear. Turbocharged engines are often better suited for mountain towing.
Q: Are EVs affected by altitude the same way gas vehicles are?
Not as much in terms of power loss, but battery range can still be impacted by cold mountain weather and elevation changes.
