Can aerodynamic upgrades really make a Tesla Model 3 more efficient on a cross-country road trip?
A new real-world test from Tesla aftermarket specialist Unplugged Performance suggests they can make a measurable difference—but the results also reveal why choosing the right wheels, tires, and aerodynamic accessories matters.
A 2025 Tesla Model 3 Long Range RWD equipped with the company's new Range Booster Package completed a 2,871-mile trip across the United States, averaging 238.9 Wh/mi, compared with 248.4 Wh/mi during an earlier trip in the same car before the modifications.
That's approximately 4.2% less energy consumed per mile.
The result is particularly interesting for Model 3 Highland owners considering aerodynamic wheels, factory Photon wheel covers, or aftermarket wheel cover upgrades.
But how much of that improvement came from the wheels? Do 18-inch wheels really outperform 19-inch wheels? And can a set of wheel covers help improve Tesla range without replacing the entire wheel?
Updated October 14, 2026: We've added details about Tesla's redesigned wheel configuration interface in software update 2026.32, including how supported vehicles display aerodynamic wheel covers and why choosing the correct wheel setup matters for range estimates.
Tesla Model 3 Cross-Country Efficiency Test: What Happened?
On October 12, 2026, Unplugged Performance introduced its new Range Booster Package for the refreshed Tesla Model 3.
The package combines four aerodynamic and chassis modifications designed to reduce energy consumption, particularly during highway driving.
A 2025 Model 3 Long Range RWD equipped with the package traveled from Southern California to New York City while using Tesla Full Self-Driving (Supervised).
The team reported completing the journey in 45 hours and 37 minutes, including 23 Tesla Supercharger stops.
Model 3 Efficiency Test Results
| Metric | Previous Stock Run | Modified Run |
|---|---|---|
| Vehicle | 2025 Model 3 Long Range RWD | Same vehicle |
| Average energy consumption | 248.4 Wh/mi | 238.9 Wh/mi |
| Energy per 100 miles | 24.84 kWh | 23.89 kWh |
| Difference | — | 9.5 Wh/mi lower |
| Relative energy reduction | — | Approximately 4.2% reported |
（The reported improvement is 4.2%, although the two published average consumption figures calculate to approximately 3.8% using the stock run as the baseline.）
The modified run covered 2,871 miles.
Over a hypothetical 1,000-mile trip, a 9.5 Wh/mi reduction would correspond to approximately 9.5 kWh less energy consumed, assuming the same difference could be maintained under comparable conditions.
However, this was not a controlled laboratory test. Weather, traffic, routes, driving conditions, and software versions differed between the two trips.
The 4.2% result applies to the complete vehicle configuration—not to the wheels or wheel covers alone.

What Upgrades Helped the Model 3 Use Less Energy?
The $6,093 Range Booster Package includes four components.
1. 18-Inch Aerodynamic Forged Wheels
The package uses Unplugged Performance's 18-inch UP-RW Road Warrior forged wheels.
Each wheel weighs approximately 22.4 pounds and features an integrated aerodynamic disc designed to reduce turbulence around the rotating wheel.
According to Unplugged Performance, its computational fluid dynamics simulations placed the wheel design within 0.010 Cd of Tesla's factory 18-inch Photon wheel with its aerodynamic cover installed.
That is a manufacturer-reported simulation comparison, not an independent real-world range test.
2. Carbon Fiber Rear Spoiler
The rear spoiler is designed to manage airflow leaving the trunk area.
Its purpose is not simply to create a sportier appearance, but to help optimize the vehicle's aerodynamic behavior.
3. Rear Diffuser Extension
The carbon fiber diffuser extension modifies airflow underneath and behind the vehicle.
Together with other aerodynamic components, rear airflow management can influence drag and vehicle stability.
4. Moderate Lowering Springs
Lowering the vehicle changes how air moves underneath the body.
This can reduce aerodynamic drag in certain configurations, particularly at higher speeds.
However, lowering also affects ground clearance and may introduce practical trade-offs for everyday driving.
The important takeaway is that the package approaches efficiency as a complete aerodynamic system.
A different wheel design, a rear spoiler, and reduced ride height can all influence the result.
The test does not establish how much energy any single component saved.
Why Do Aero Wheels and Wheel Covers Affect Tesla Range?
When a Tesla moves through the air, it must overcome aerodynamic resistance.
The faster it travels, the more important that resistance becomes.
Aerodynamic drag force increases approximately with the square of vehicle speed, meaning the energy needed to overcome air resistance per mile generally rises substantially at highway speeds.
Wheels are an important part of this equation.
Unlike the relatively smooth body panels of a Tesla Model 3, wheels rotate and contain openings, spokes, and other surfaces that can disturb airflow.
How Aerodynamic Wheel Covers Work
A well-designed aerodynamic wheel cover can reduce airflow disturbance around the wheel by covering some of the openings between the spokes.
This may help reduce aerodynamic drag.
However, the result depends on the shape of the cover, the wheel underneath, and the vehicle's overall airflow.
Not all aftermarket wheel covers deliver the same efficiency.
A design that looks more aerodynamic does not automatically perform better than Tesla's factory aero cover.
Likewise, replacing a factory Photon cover with a more aggressive-looking aftermarket cover does not guarantee additional range.
For owners considering a wheel cover upgrade, the most useful questions are:
-
Is the cover designed for the exact factory wheel?
-
Has its aerodynamic performance been tested?
-
Does it remain securely attached at highway speeds?
-
Does it protect the wheel rim?
-
Does it offer the appearance you want without requiring a complete wheel replacement?
These factors matter more than broad claims about increasing range.
October 2026 Update: Tesla 2026.32 Adds Aero Wheel Cover Settings
Tesla's 2026.32 software update introduces a redesigned Wheel & Tire configuration interface, giving owners a more visual way to select their factory wheel setup—including supported configurations with or without aerodynamic wheel covers.
The redesigned menu was first reported in September 2026 and received renewed attention in an October 13 roundup of Tesla's lesser-known software changes.
For Model 3 and Model Y owners, the update highlights an important connection between physical wheel configurations, the vehicle's on-screen appearance, and estimated driving range.
How to Change Aero Wheel Cover Settings in Your Tesla
On vehicles with the supported software and wheel configurations:
-
Park your Tesla safely.
-
Open Controls on the central touchscreen.
-
Navigate to Service → Wheel & Tires.
-
Open the available wheel configuration options.
-
Select the factory wheel design that matches your vehicle.
-
Where supported, choose the appropriate configuration with or without aerodynamic covers.
The redesigned interface displays available wheel styles visually, making it easier to identify the correct setup.
Note: Available options depend on the vehicle model, factory wheel design, and installed software. Not every Model 3 or Model Y will show the same choices.
Does Changing the Wheel Cover Setting Improve Tesla Range?
Changing the on-screen wheel cover setting does not physically reduce aerodynamic drag.
Actual energy consumption depends on the wheels and covers installed on the vehicle, along with tire selection, driving speed, weather, and other conditions.
However, Tesla uses wheel configuration information when calculating certain range estimates. Selecting the appropriate factory configuration can therefore help align the vehicle's software settings with its physical setup.
This distinction is important:
Removing an aerodynamic wheel cover can change real-world airflow. Changing its appearance in the touchscreen visualization cannot.
Owners should also avoid assuming that choosing a different wheel design in the menu will increase battery capacity or improve driving efficiency.
What Does This Mean for Aftermarket Wheel Covers?
The update is particularly relevant to owners who replace their original Tesla aero covers with aftermarket designs.
For example, some 2024+ Model 3 Highland vehicles feature factory 18-inch Photon wheels with removable aerodynamic covers.
Owners may prefer a different wheel appearance while keeping their existing factory wheels and tires.
However, Tesla's software menu represents supported factory wheel configurations. It does not necessarily provide a dedicated visualization for every third-party wheel cover.
Installing aftermarket covers does not automatically mean the touchscreen will display their exact design.
For owners considering a visual upgrade, Yeslak offers UberTurbine-style wheel covers for compatible Model 3 Highland 18-inch Photon wheels.
Before purchasing, confirm your vehicle's actual factory wheel design—not just the model year or the appearance shown on the touchscreen.
Photon, Prismata, Nova, and Dark Nova wheels should not be assumed to share the same wheel cover fitment.
The Connection to the Model 3 Efficiency Test
The new software setting also provides useful context for the Model 3 cross-country efficiency test discussed earlier in this article.
That test compared two complete vehicle configurations, with the modified Model 3 using aerodynamic forged wheels, a rear spoiler, a diffuser extension, and lowering springs.
Tesla's updated wheel configuration interface reinforces why wheel setup matters, but it does not independently validate the efficiency of any particular aftermarket cover.
For owners focused on range, the best approach is to combine accurate vehicle settings with real-world energy consumption data and accessories designed for the correct factory wheels.

Tesla Model 3 Photon Wheels: Why the Factory Aero Covers Matter
Tesla's 18-inch Photon wheels are an important reference point for aerodynamic wheel design on the refreshed Model 3 Highland.
The factory configuration combines an 18-inch wheel with a removable aerodynamic cover.
The cover changes the wheel's external shape and helps manage airflow around the rotating assembly.
For drivers who prioritize efficiency, retaining the factory aero covers is a reasonable baseline.
Owners who prefer a different appearance can consider aftermarket wheel covers designed specifically for the Photon wheel.
For example, Yeslak offers UberTurbine-style wheel covers for the Model 3 Highland's factory 18-inch Photon wheels.
These covers provide a more aggressive, performance-inspired appearance while retaining the original 18-inch wheel and tire setup.
They also extend over the wheel edge to help protect against everyday curb contact.
However, the cross-country efficiency test discussed above did not evaluate Yeslak wheel covers, and it should not be interpreted as proof of a particular range improvement from them.
Tesla Model 3 18-Inch vs. 19-Inch Wheels: Which Is Better for Range?
For many Model 3 owners, the choice between 18-inch and 19-inch wheels involves more than appearance.
Wheel diameter can influence ride comfort, tire selection, wheel weight, and efficiency.
But wheel size alone does not determine energy consumption.
18-Inch Wheels
An 18-inch wheel setup often provides more tire sidewall than a comparable 19-inch setup.
Depending on the wheel and tire combination, potential advantages include:
-
More compliant ride quality.
-
A wider selection of comfort-oriented or efficiency-focused tires.
-
Potentially lower wheel and tire weight.
-
Availability of factory aerodynamic wheel covers on compatible Model 3 configurations.
These characteristics can make 18-inch wheels attractive to drivers who prioritize everyday comfort and range.
19-Inch Wheels
Larger wheels are often selected for appearance and handling characteristics.
They may offer:
-
A sportier visual profile.
-
Different steering and handling characteristics.
-
Different tire performance options.
However, larger wheels can also increase weight or use tires with different rolling resistance.
In some configurations, this can increase energy consumption.
The exact difference depends on the complete wheel and tire package.
18-Inch vs. 19-Inch Model 3 Wheels
| Factor | 18-Inch Wheels | 19-Inch Wheels |
|---|---|---|
| Ride comfort | Often more compliant | Often firmer |
| Tire sidewall | Generally taller | Generally shorter |
| Efficiency potential | Often favorable with aero design | Depends on design and tires |
| Appearance | Practical or sporty | Often more aggressive |
| Tire replacement cost | Often lower | Often higher |
| Wheel cover compatibility | Factory-wheel specific | Factory-wheel specific |
For a driver whose priority is maximum range, an efficiency-focused 18-inch setup is often a sensible choice.
But a carefully designed 19-inch wheel may outperform a poorly optimized 18-inch setup under some conditions.
The correct comparison is the complete wheel and tire assembly—not diameter alone.
Model 3 Highland Wheel Cover Compatibility: Photon, Prismata, Nova, and Dark Nova
Before buying Tesla wheel covers, it's essential to identify the factory wheel installed on your vehicle.
This is especially important because Tesla has introduced different wheel designs across Model 3 trims, production years, and markets.
Two wheels can have the same diameter without sharing the same cover mounting geometry.
Tesla Model 3 Wheel Compatibility Guide
| Factory Wheel | Size | Wheel Cover Compatibility |
|---|---|---|
| Photon | 18 inches | Requires Photon-specific covers |
| Prismata | 18 inches | Requires Prismata-specific covers |
| Original Nova | 19 inches | Requires covers verified for original Nova wheels |
| Dark Nova | 19 inches | Requires covers verified for Dark Nova wheels |
| Performance-specific wheels | Varies | Requires exact wheel-specific fitment verification |
2024+ Model 3 Highland With 18-Inch Photon Wheels
For applicable Model 3 Highland vehicles equipped with factory 18-inch Photon wheels, Yeslak offers several replacement cover styles.
These include UberTurbine-inspired designs that change the appearance without replacing the underlying wheel.
2026+ Model 3 Standard With 18-Inch Prismata Wheels
Some newer Model 3 Standard configurations use 18-inch Prismata wheels.
Although these are also 18-inch wheels, their design and mounting geometry differ from Photon wheels.
Photon-specific wheel covers are not compatible with Prismata wheels.
Yeslak offers wheel covers specifically designed for the Model 3 Standard's 18-inch Prismata wheels.
19-Inch Nova and Dark Nova Wheels
The original Nova and newer Dark Nova wheel designs should not be treated as interchangeable without product-specific confirmation.
A wheel cover designed for an 18-inch Photon wheel will not fit a 19-inch Nova or Dark Nova wheel.
Even accessories designed for an earlier 19-inch Nova configuration should not automatically be assumed compatible with Dark Nova.
Always confirm the factory wheel name, diameter, vehicle trim, and product fitment before ordering.
Do Aftermarket Tesla Wheel Covers Really Improve Range?
They can affect aerodynamic efficiency, but there is no universal percentage that applies to every Tesla or every wheel cover design.
A well-designed cover may reduce drag compared with an uncovered wheel.
However, replacing one aerodynamic cover with another may produce a smaller difference, no measurable difference, or even worse efficiency.
That is why test conditions matter.
For a meaningful comparison, owners should ideally keep the following variables consistent:
-
Vehicle and wheel configuration.
-
Tire model and tire pressure.
-
Driving speed and route.
-
Outside temperature and wind conditions.
-
Vehicle load and climate-control settings.
Energy consumption should be measured over enough distance to reduce the influence of short-term variations.

Is It Worth Upgrading Your Model 3 Wheels for Efficiency?
The answer depends on your priorities.
If your main goal is maximum efficiency, start with the fundamentals: properly inflated tires, appropriate tire selection, smooth driving, and a wheel configuration designed for low aerodynamic drag.
If you already have factory Photon wheels with their original aero covers, you may already have an efficiency-focused setup.
Replacing them purely for range improvement requires evidence that the alternative performs better.
If your priority is appearance, rim-edge coverage, and keeping your existing wheels, vehicle-specific aftermarket wheel covers may be a more affordable alternative to purchasing an entirely new wheel set.
If you are considering a full aerodynamic package, the Unplugged Performance test provides an interesting real-world example—but the $6,093 package is a substantially different investment.
FAQ
How much efficiency did the modified Tesla Model 3 gain?
The test vehicle averaged 238.9 Wh/mi after modification, compared with 248.4 Wh/mi during an earlier stock run. The reported reduction was approximately 4.2% in energy consumption per mile.
The two journeys were not conducted under identical conditions.
Did wheel covers alone improve Model 3 efficiency by 4.2%?
No. The vehicle used aerodynamic forged wheels, a rear spoiler, a diffuser extension, and lowering springs. The test did not isolate the efficiency contribution of the wheels or wheel covers.
Are Tesla's 18-inch Photon wheels efficient?
Tesla's factory Photon wheels use aerodynamic covers intended to help manage airflow. They provide an efficiency-oriented baseline for compatible Model 3 Highland vehicles.
Do 18-inch wheels always provide more range than 19-inch wheels?
No. Smaller wheels can have advantages, but actual efficiency depends on wheel design, tire choice, weight, and driving conditions.
Can I install Photon wheel covers on Prismata wheels?
No. Photon-specific covers are not designed for Prismata wheels, even though both may be 18 inches in diameter.
Will 18-inch Photon wheel covers fit 19-inch Dark Nova wheels?
No. These are different factory wheel configurations and require different accessories.
Do aerodynamic upgrades matter more on highways?
Generally, yes. Aerodynamic resistance becomes more significant as speed increases, making aerodynamic improvements particularly relevant during sustained highway driving.
Can I Change My Tesla's Aero Wheel Cover Settings After Update 2026.32?
On supported vehicles, Tesla's redesigned Wheel & Tire menu lets owners select available factory wheel configurations, including options with or without aerodynamic covers. Go to Controls → Service → Wheel & Tires to check the choices available for your vehicle.
Does Tesla's Wheel Cover Setting Change Actual Driving Range?
Changing the setting alone does not improve physical aerodynamic efficiency. However, the selected wheel configuration may affect the vehicle's estimated range calculations. Real-world efficiency depends on the wheels, tires, covers, and driving conditions.
Final Thoughts: Aero Wheels Matter, but Real-World Testing Matters More
The latest Tesla Model 3 cross-country efficiency test highlights how vehicle aerodynamics can influence energy consumption over long distances.
The modified Model 3 achieved an impressive 238.9 Wh/mi average across 2,871 miles, using approximately 4.2% less energy per mile than during the same vehicle's earlier stock run.
But the result should be understood in context.
It was a comparison of two real-world journeys using a complete aerodynamic upgrade package, not a controlled test of wheel covers alone.
For everyday Model 3 owners, the practical lesson is simple: wheel design matters, but so do tire choice, speed, weather, and vehicle configuration.
Whether you keep your factory Photon covers, switch to compatible aftermarket covers, or consider an entirely different wheel setup, choose products designed for your exact factory wheels and be cautious of unsupported range claims.
A good upgrade should match your vehicle, your driving needs, and your expectations—not just a headline percentage.
