98 MPG combined is an astounding figure for anything that resembles an SUV, much less one with supercar acceleration. The 2024 Tesla Model X Plaid on 20-inch wheels achieves this remarkable efficiency through electric power, not through hybrid systems or diesel. This isn’t a vehicle purchased by penny-pinchers, it’s a status symbol, a technology showcase, and a family hauler. Its buyers willingly pay a premium for performance and exclusivity, but that doesn’t mean they’ll ignore the financial benefits of near-zero running costs.

City and highway performance

Breaking down the 2024 Model X Plaid’s EPA ratings reveals its strengths and weaknesses. In the city, it achieves an impressive 102 MPG equivalent. Stop-and-go traffic allows the regenerative braking system to shine, recouping energy that would otherwise be lost as heat in a conventional vehicle. On the highway, this figure drops to 92 MPG. While still exceptional, the reduced regeneration opportunities at higher speeds mean the Model X Plaid relies more on drawing power directly from the battery, slightly impacting efficiency. This difference underscores the advantage electric vehicles have in urban environments compared to purely gas-powered cars. Find all all Tesla fuel economy data on our site.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Tesla Model X Plaid (20-inch wheels) at $800. This figure is calculated based on driving 15,000 miles per year, using a combination of city and highway driving cycles, and factoring in the national average electricity prices. While electricity prices fluctuate regionally, and individual driving habits vary, this $800 estimate provides a valuable point of comparison against gasoline-powered alternatives. Remember that this figure assumes charging primarily at home; using public fast-charging networks more frequently will increase your costs.

Real-world expectations

While the EPA figures provide a standardized baseline, real-world fuel economy will differ based on individual driving habits, weather conditions, and terrain. Aggressive acceleration, frequent use of “Plaid” mode, and sustained high-speed driving will all significantly reduce the vehicle’s efficiency. Cold temperatures can also negatively impact battery performance, leading to reduced range and lower MPG figures. On the other hand, gentle acceleration, optimized route planning, and moderate temperatures can help drivers achieve or even exceed the EPA estimates.

How it compares

Conventional SUVs with similar performance capabilities are simply in a different league when it comes to fuel consumption. A Porsche Cayenne Turbo S E-Hybrid, while offering comparable acceleration, achieves just 18 MPG combined when running on gasoline alone. Even the hybrid version of the Lexus RX, a more mainstream luxury SUV, manages only 36 MPG combined. The Rivian R1S, another electric SUV competitor, nets 76 MPG combined. The Model X Plaid’s closest rival is the upcoming Cadillac Escalade IQ, which is estimated to get around 85 MPG combined. For buyers prioritizing both performance and less gas, the Model X Plaid outperforms nearly all its competitors by a significant margin.

Tips to maximize efficiency

Take advantage of regenerative braking. Adjust the regenerative braking setting to your preference, but remember that a higher setting allows for more aggressive deceleration and greater energy recapture, especially in city driving. Mastering one-pedal driving will significantly improve your efficiency.

Precondition the battery. Before heading out on a trip, especially in cold weather, use the Tesla app to precondition the battery. This warms the battery to its optimal operating temperature while plugged in, minimizing range loss during the initial miles of your drive.

Optimize your tire pressure. Ensure your tires are inflated to the recommended pressure listed on the doorjamb sticker. Underinflated tires increase rolling resistance and reduce fuel efficiency. Check your pressures regularly, especially with temperature fluctuations.

Minimize aerodynamic drag. Remove any unnecessary roof racks or cargo carriers when not in use. These accessories increase aerodynamic drag and reduce the vehicle’s efficiency, particularly at highway speeds.
