Driving south from Denver on I-25, the silhouette of Pikes Peak begins to dominate the horizon, serving as both a beautiful landmark and a silent reminder of the physics at play. For many of our guests at Frontier Tesla, the trip from Denver to Colorado Springs is the first real test of their electric vehicle experience. You’ve booked the car, you’ve picked it up downtown, and now you’re staring at the navigation screen wondering if the "Monument Tax"—that grueling climb over Monument Hill—will eat your battery alive.
When you’re looking at a Tesla Model 3 rental range, the numbers on the screen are just the starting point. The real-world performance on the Colorado Front Range is a dance between battery chemistry, thin mountain air, and a 2,000-foot elevation swing. We get asked the same three questions almost every day: Will the Standard Range make it? Is the Long Range actually necessary? And just how much range will I lose on that climb?
I’ve driven this stretch of asphalt hundreds of times in every configuration of the Model 3. Here is the ground truth about navigating the I-25 corridor in a Tesla.
The Tale of Two Batteries: RWD vs. Long Range
To understand which car you need, we have to look at what’s under the floorboards. The current Tesla Model 3 Rear-Wheel Drive (formerly known as the Standard Range) utilizes a Lithium Iron Phosphate (LFP) battery. It’s rugged, it loves being charged to 100%, and it offers an EPA-estimated range of roughly 272 miles.
On the other side of the aisle, the Model 3 Long Range uses a Nickel Cobalt Aluminum (NCA) chemistry. It’s denser, heavier, and provides an EPA-estimated 341 miles. But in the context of a Colorado Springs trip, these numbers are theoretical. You aren't driving in a vacuum at 55 mph; you're fighting crosswinds at 75 mph while ascending to 7,352 feet above sea level.
Will a Standard Range Model 3 make it to Colorado Springs without charging?
The short answer is a resounding yes. If you pick up a Standard Range Model 3 from our downtown Denver location with a full charge, you can make it to Colorado Springs with plenty of breathing room.
The distance from downtown Denver to downtown Colorado Springs is approximately 70 miles. Even if you factor in the elevation gain and the high speeds of I-25, you’ll likely arrive in the Springs with 60% to 70% of your battery remaining. We’ve found that even in less-than-ideal conditions—think a stiff headwind or a chilly October morning—the Standard Range handles the one-way trek without breaking a sweat. You won't be looking for a charger in Castle Rock unless you started the trip with less than half a tank of electrons.
The Monument Hill Factor: Understanding the Elevation Tax
If you’re new to EVs, the way elevation affects your Tesla Model 3 rental range can be startling. Internal combustion engines actually lose efficiency as they climb because the air gets thinner; Teslas don't have that problem, but they do have to fight gravity.
Monument Hill is the highest point on I-25 between Canada and Mexico. As you climb from Denver’s 5,280 feet to the summit’s 7,352 feet, your energy consumption (measured in Watt-hours per mile, or Wh/mi) will spike.
How much range is lost on I-25 due to elevation changes?
Based on our fleet data and real-world testing, you can expect to "lose" about 15 to 20 miles of indicated range specifically due to the elevation gain on the way south. While the odometer says you’ve traveled about 20 miles from Castle Rock to the summit of Monument Hill, your battery might show a drop equivalent to 35 or 40 miles of range.
However, here is the magic of regenerative braking: what goes up must come down. On the descent into Colorado Springs, your Tesla will actually start putting energy back into the battery. You’ll see your consumption drop to near zero, or even negative numbers, as gravity does the work for you. By the time you reach Garden of the Gods, you’ve recovered a significant portion of what you "lost" on the climb.
According to a 2023 study by Geotab on EV efficiency, elevation changes can impact range by as much as 20% in mountainous regions, but the net loss is often mitigated by regen on the return leg. In our experience, the net "elevation tax" for a Denver-to-Springs round trip is surprisingly low—usually less than 5% of the total battery capacity.
Is the Long Range Model 3 necessary for Denver to Colorado Springs round trips?
This is where the conversation gets nuanced. If you are doing a straight shot down and back—say, for a business meeting or a quick lunch at The Broadmoor—the Standard Range can technically do it. A 140-mile round trip on a 272-mile battery seems like a no-brainer.
But here’s the thing: Colorado weather is rarely "standard."
The Case for the Long Range
If you’re planning a day trip that involves more than just driving to the Springs and back, we almost always recommend the Long Range. Here’s why:
- The Winter Reality: In 20-degree weather, an EV can lose 20% to 30% of its range just to keep the cabin warm. If you’re doing a round trip in January, that 272-mile range is suddenly closer to 190 miles. Add in the I-25 speeds and the elevation, and you’re looking at a very tight finish.
- The "Springs Sprawl": Colorado Springs is huge. If you decide to drive up to the top of Pikes Peak (a massive energy drain) or spend the afternoon exploring Cheyenne Mountain State Park, your mileage will add up fast.
- Speed Limits: I-25 has a 75 mph speed limit for much of the drive. Drag increases exponentially with speed. Driving at 80 mph (the flow of traffic) uses significantly more energy than driving at 65 mph.
So, is it necessary? No. You can always hit the Supercharger at the Tejon Street station or the one near North Nevada Ave. But if you want to complete the round trip without a 20-minute charging stop, the Long Range is your best friend. It provides that "buffer of confidence" that makes the trip feel like a vacation rather than a math problem.
Key Takeaways for Your Colorado Trip
- Standard Range is fine for one-way: You’ll arrive with plenty of charge to explore the city.
- Long Range is the round-trip king: It eliminates the need to charge before heading back to Denver, especially in winter.
- Trust the Nav: Tesla’s built-in navigation is incredibly accurate at predicting your arrival percentage, factoring in both elevation and real-time wind data.
- Pre-condition in winter: If it’s cold, use the app to warm up the car while it’s still plugged in at our pickup location. This saves a massive amount of energy.
The Physics of the Return Trip
One of the most satisfying parts of renting a Tesla for a Colorado Springs trip is the drive back to Denver. Because Denver is lower than the Springs, the return trip is a net descent. You’ll find that you use significantly less energy heading north than you did heading south.
I’ve seen guests arrive back at our downtown office having used only 10% of their battery for the final 40 miles of the trip. The car feels like it’s coasting on air. This is the beauty of the Tesla Model 3 rental range; it’s dynamic. It rewards smart driving and utilizes the geography of the Rockies to its advantage.
Frequently Asked Questions
Can I make it to the top of Pikes Peak in a Standard Range?
Yes, but it will consume about 25-30% of your battery just for the climb. The good news? You’ll gain about 10-15% back on the way down thanks to regenerative braking. Just make sure you start the climb with at least 50% charge to be safe.
Where are the best places to charge in Colorado Springs?
The Tesla Supercharger network in the Springs is excellent. The station at 704 S Tejon St is great because it’s near several local coffee shops. There’s also a large station at the Chapel Hills Mall on the north end of town, which is perfect for a quick top-off before the climb back over Monument Hill.
Does the Autopilot help with range?
Actually, yes. By maintaining a consistent speed and avoiding unnecessary acceleration, Autopilot (or Full Self-Driving) can be more efficient than a human driver, especially on the long, straight stretches of I-25.
What happens if I run low on battery during the climb?
The car will give you plenty of warning. It will suggest a lower maximum speed to conserve energy and automatically route you to the nearest Supercharger. You’d have to ignore about five different warnings to actually get stranded.
Planning Your Frontier Tesla Experience
We believe that the journey should be as enjoyable as the destination. Whether you’re heading to the Springs for a hike in Red Rock Canyon or a tour of the Air Force Academy, choosing the right tool for the job makes all the difference.
If you’re staying in the Springs overnight and have access to a charger at your hotel, the Standard Range is a fantastic, cost-effective choice. If you’re a "power user" doing a whirlwind day trip and don't want to think about batteries, go for the Long Range.
