You’ve finally cleared your calendar for a weekend escape to the coast. The bags are packed, the playlist is curated, and the only thing standing between your driveway in Buckhead and a sunset dinner on River Street is the 250-mile stretch of Georgia asphalt. But here’s the dilemma we see every day at Frontier Tesla: which keycard should you grab?
Choosing between a Tesla Model 3 vs Model Y rental in Atlanta isn't just about picking a car size. It’s about matching the vehicle to the specific rhythm of the "Atlanta-Savannah Run." I’ve driven this route dozens of times in both vehicles. I’ve monitored the battery degradation on humid July afternoons and navigated the tight, cobblestone squares of Savannah’s historic district.
The truth? The "best" car depends entirely on whether you’re prioritizing aerodynamic efficiency on I-16 or the ability to bring an extra cooler for the beach. Let’s break down the data, the drive, and the dollars to see which EV earns its spot in your driveway.
The I-16 Efficiency Test: Aerodynamics vs. Airspace
Georgia highways are a unique beast. Once you clear the chaotic gravitational pull of the I-75/I-85 connector, the road opens up into long, flat stretches of pine-lined highway. This is where the physics of these two cars diverge.
Range for Georgia Highways: Does the Model 3 or Model Y Win?
If you are looking for the absolute best range for Georgia highways, the Model 3 is the undisputed champion. It comes down to the drag coefficient. The Model 3 boasts a sleek 0.219 Cd, while the Model Y, being taller and bulkier, sits at 0.23 Cd.
On the long, 70-mph stretches of I-16, wind resistance is your biggest battery drain. In our fleet testing, we’ve found that a Model 3 Long Range consistently achieves about 10-12% better efficiency (measured in Watt-hours per mile) than a Model Y Long Range on the Atlanta-to-Savannah route.
What does this mean for you? It means that in a Model 3, you can often make the trip with a single, short 15-minute "splash and go" at the Metter Supercharger. In a Model Y, especially if you’re fighting a headwind or running the AC at full blast to combat the Georgia humidity, you might find yourself needing a slightly longer stop or a more conservative speed to arrive with a comfortable buffer.
The Impact of Southern Heat on Range
We can’t talk about Georgia driving without mentioning the heat. According to data from Recurrent Auto, EVs can lose up to 15% of their range when temperatures climb above 95°F, primarily due to the energy required to cool the battery and the cabin.
Because the Model Y has a significantly larger cabin volume and more glass surface area (especially with that gorgeous panoramic roof), the HVAC system has to work harder. If you’re renting during a July heatwave, the Model 3’s smaller cabin stays cool more efficiently, preserving more of those precious electrons for the actual drive.
The Cargo Conundrum: Which Tesla Has More Trunk Space?
Here is where the Model Y starts to claw back its lead. If your "weekend trip" involves more than two people or includes gear for Tybee Island, the Model 3 might feel a bit tight.
Real-World Trunk Capacity for Weekend Trips
When people ask which Tesla has more trunk space for a weekend trip, the answer is numerically lopsided. The Model 3 offers about 15 cubic feet of trunk space. It’s a traditional sedan trunk—deep, but with a narrow opening. You can fit two large suitcases and a few soft bags, but forget about bulky items.
The Model Y, however, is a hatchback. It offers 30.2 cubic feet behind the second row. If you fold those seats down, you’re looking at a massive 72 cubic feet of storage.
The "Savannah Cooler" Test: I recently took a Model 3 to Savannah for a wedding. We fit two carry-ons and a garment bag easily. But when we tried to add a hard-sided Yeti cooler? No go. The trunk opening was too shallow. We had to put the cooler in the back seat, which isn't ideal if you have passengers. In the Model Y, that same cooler disappears into the sub-trunk (the deep well under the main floor), leaving the entire main cargo area free for luggage.
The Frunk Factor
Don't forget the "frunk" (front trunk). Both cars have them, but the Model Y’s frunk is slightly deeper. It’s the perfect spot for takeout from Zunzi’s in Savannah—keep the smell of those "Conquistador" sandwiches out of the main cabin.
Is the Model Y Worth the Extra Rental Cost for Savannah?
This is the question that hits the wallet. Generally, a Model Y rental in Atlanta carries a premium of $20 to $40 per day over a Model 3. Over a three-day weekend, you’re looking at an extra $100. Is it worth it?
The Comfort of the "Command View"
The Model 3 sits low. It feels like a sports car. You’re hunkered down, which is fun for spirited driving, but can feel fatiguing on a three-hour highway drone.
The Model Y features "stadium seating." The seats are mounted on risers, giving you a much higher hip point. You aren't just sitting higher; you’re sitting more upright. For the long, straight stretches of I-16, this "Command View" of the road reduces neck strain and makes it easier to spot traffic patterns ahead.
If you have back issues or simply prefer not to "climb out" of a car, the Model Y is easily worth the extra cost.
Parking in the Historic District
Here is a counter-point: Savannah’s historic district was designed for horse-drawn carriages, not SUVs. The streets are narrow, and parking spots near Forsyth Park are notoriously tight.
The Model 3 is about 2 inches narrower and 7 inches shorter than the Model Y. While that doesn't sound like much, it makes a world of difference when you’re trying to parallel park on Jones Street while a tour trolley is breathing down your neck. If you plan on spending 90% of your time in the downtown core, the Model 3’s smaller footprint is a massive tactical advantage.

Navigating the Atlanta-Savannah Charging Corridor
One thing you don't have to worry about with either rental is "range anxiety." The route from Atlanta to Savannah is one of the best-supported charging corridors in the Southeast.
- Macon, GA: The gateway to South Georgia. There are multiple Superchargers here, including a large station at the Target on Riverside Drive. It’s the perfect spot for a bathroom break and a Starbucks run.
- Metter, GA: This is the strategic midpoint. If you’re driving a Model Y and you’ve been doing 80 mph, you’ll likely need to stop here. It’s a quick, reliable stop right off the exit.
- Savannah (Pooler): Just outside the city, the Pooler Superchargers are surrounded by restaurants.
- Savannah (Downtown): There are urban chargers located in parking decks, but be aware that these are slower than the highway Superchargers.
Pro Tip: We always recommend our renters use the in-car navigation. It will automatically pre-condition the battery as you approach a Supercharger, which can cut your charging time by up to 25%.
The FSD Factor: Making I-16 Disappear
At Frontier Tesla, our vehicles come equipped with Full Self-Driving (FSD) capability. On the Atlanta-Savannah run, this is a game-changer.
I-16 is notoriously boring. It is a straight line through a forest. Using FSD (Supervised) allows the car to handle the lane changes, speed adjustments, and even the interchange from I-75 to I-16. While you still need to stay attentive, the cognitive load is significantly reduced.
In my experience, the Model Y feels slightly more stable on FSD during windy days on the highway. Its heavier curb weight (about 4,400 lbs vs the Model 3’s 4,000 lbs) makes it feel more planted when passing large semi-trucks.
The Verdict: Which Should You Rent?
After thousands of miles on these roads, here is my professional recommendation:
Choose the Tesla Model 3 if:
- You are traveling solo or as a couple.
- You want the most efficient drive with the fewest charging stops.
- You enjoy a sporty, low-to-the-ground driving feel.
- You plan on doing a lot of tight city parking in Savannah.
- You want to save $100 on the rental for a fancy dinner at The Grey.
Choose the Tesla Model Y if:
- You have more than two people or are traveling with kids.
- You are bringing bulky gear (coolers, golf clubs, beach chairs).
- You prefer a higher seating position for better visibility.
- You don't mind an extra 10 minutes at the charger in exchange for massive interior space.
- You want the easiest entry and exit experience.
Frequently Asked Questions (FAQ)
1. Is the Model Y worth the extra rental cost for a trip to Savannah?
Yes, if you value interior space and a higher driving position. The Model Y’s "stadium seating" significantly reduces fatigue on the three-hour drive. However, if you are a solo traveler on a budget, the Model 3 provides a nearly identical tech experience for less money.
2. Which Tesla has more trunk space for a weekend trip?
The Model Y is the clear winner. With 30.2 cubic feet of space behind the seats and a wide hatchback opening, it can accommodate bulky items like coolers and strollers that simply won't fit through the Model 3’s narrow trunk lid.
3. Does the Model 3 or Model Y have better range for Georgia highways?
The Model 3 has better range and efficiency. Its lower profile and superior aerodynamics mean it uses less energy to cut through the air at highway speeds. Expect about 10% better mileage in a Model 3 compared to a Model Y on the I-16 corridor.
