101 MPGe combined is an incredible number for a four-door sedan that can outrun supercars in the quarter mile. The fact that the 2022 Tesla Model S Plaid with 21-inch wheels achieves this rating while offering limousine-like space and advanced technology shows the efficiency of Tesla’s powertrain and the dedication of Plaid owners to electric driving.

City and highway performance

The EPA rates the Model S Plaid (21-inch wheels) at 102 MPGe in the city and 99 MPGe on the highway. These numbers show a key characteristic of electric vehicles: they often achieve better efficiency in stop-and-go city driving than at consistent highway speeds. This is because regenerative braking captures energy during deceleration in city traffic, sending it back to the battery. On the highway, there’s less regenerative braking, and the motor must work harder to overcome aerodynamic drag. The slightly lower highway figure is therefore anticipated but still represents exceptional efficiency, especially considering the Plaid’s immense power output.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Tesla Model S Plaid (21-inch wheels) at $750. This calculation is based on driving 15,000 miles per year and using the national average electricity prices at the time of testing. It is a strong reminder of the potential savings that come with switching from gasoline to electricity, though individual costs will vary based on local electricity rates and driving habits. Owners can use this figure as a baseline when budgeting for annual running costs.

Real-world expectations

While the EPA numbers provide a standardized comparison, real-world MPGe can vary significantly based on driving style, ambient temperature, and terrain. Aggressive acceleration, frequent use of “launch mode,” and sustained high-speed driving will deplete the battery faster, reducing overall efficiency. Extremely cold temperatures can also negatively impact battery performance. However, Plaid owners often find ways to optimize their driving to maximize range and efficiency. Knowing the car’s capabilities and adjusting driving habits accordingly are key to achieving figures close to the EPA estimates.

How it compares

The most obvious comparison is to other high-performance electric vehicles. The Porsche Taycan Turbo S, for instance, is rated at 69 MPGe combined. While undoubtedly a thrilling car, it lags behind the Model S Plaid in terms of efficiency. Even the standard, non-Plaid Model S with 19-inch wheels achieves 120 MPGe combined, showing the trade-off between outright performance and maximum efficiency. Comparing to traditional gasoline-powered super-sedans reveals a massive difference, even beyond EVs. The BMW M5 CS achieves around 17 MPG combined. This stark contrast underlines the economic and lowering fuel costs of choosing an electric performance car, provided that you understand the inherent trade-offs.

Tips to maximize efficiency

Gentle acceleration is the easiest way to extend your range. The Plaid’s instant torque is addictive, but resist the urge to constantly unleash its full potential. Treat the accelerator pedal with respect, and you will see a noticeable improvement in your MPGe.

Precondition the cabin while the car is still plugged in. This uses electricity from the grid to heat or cool the interior, rather than drawing power from the battery once you’re on the road. This is especially beneficial during cold weather, as heating the cabin can significantly reduce range.

Regenerative braking is helpful. Learn to anticipate traffic and lift off the accelerator early, allowing the car to slow down naturally and recapture energy. Experiment with different regenerative braking settings to find what works best for your driving style. Select the highest setting for maximum regeneration.

Plan your charging stops carefully on long trips. Use the Tesla navigation system to identify Supercharger locations along your route and factor in charging time. Consider charging to only 80% or 90% at Superchargers, as charging slows down dramatically beyond that point and you’ll save time overall. Also consider checking all Tesla fuel economy data and MODEL MPG across all years to aid in your purchasing decision.

Keep your tires properly inflated. Low tire pressure increases rolling resistance, which reduces efficiency. Check your tire pressure regularly and inflate them to the recommended levels. The sticker on the driver’s side door jamb will give you the ideal pressure.
