79 MPGe combined, that’s the EPA’s figure for the 2021 Porsche Taycan 4S with the Performance Battery. While this number may seem high for a Porsche, remember that this is an all-electric performance car, not a gasoline-powered 911. This efficiency is why many buyers wanting serious performance and Porsche prestige without the need for a thirsty engine are drawn to the Taycan.

City and highway performance

The 2021 Taycan 4S Performance Battery shows consistent efficiency across different driving environments, with an EPA rating of 79 MPGe in the city and 80 MPGe on the highway. This near-identical performance is typical of electric vehicles, which benefit from regenerative braking in stop-and-go city traffic and operate efficiently at steady highway speeds. For the Taycan 4S driver, this means predictable range regardless of whether they’re navigating urban streets or cruising down the interstate. The instantaneous torque and smooth acceleration that define the Taycan driving experience are readily available in both settings, making it a satisfying car to drive every day.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Porsche Taycan 4S Performance Battery at $950. This is based on driving 15,000 miles per year and using the national average electricity price. This is an estimate, and actual costs may vary. Factors such as local electricity rates, driving habits, and climate control usage can all influence electricity consumption. The $950 figure provides a helpful benchmark for comparing the Taycan 4S to other vehicles, especially gasoline-powered performance cars that can easily cost several thousands of dollars in fuel annually.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPGe for the 2021 Taycan 4S Performance Battery may vary. Aggressive driving, frequent use of launch control, and prolonged high-speed cruising can all decrease efficiency and range. Careful use of regenerative braking and a focus on smooth acceleration can help drivers get closer to, or even exceed, the EPA estimates. Ambient temperature also plays a role, as colder temperatures can reduce battery performance and increase energy consumption for cabin heating. Drivers should monitor their driving habits and track their energy consumption over time to get the most accurate understanding of range.

How it compares

Compared to other electric vehicles, the 2021 Taycan 4S Performance Battery compares favorably. The Tesla Model S Long Range, for instance, is rated at 120 MPGe combined, giving it a range advantage. The Audi e-tron GT, another closely related EV from the Volkswagen Group, achieves a combined rating of 82 MPGe, positioning it slightly ahead of the Taycan 4S. The Mercedes-Benz EQS 450+ attains 97 MPGe combined, a higher rating reflecting its focus on energy efficiency. These comparisons matter to the Taycan 4S buyer because they are cross-shopping luxury EVs, weighing performance against real-world range and operating costs. Often, the Porsche wins based on driving experience and brand cachet, even if other cars offer slightly better EPA numbers.

Tips to maximize efficiency

Take full advantage of the Taycan’s regenerative braking system. Experiment with different regen settings and learn how to time your deceleration in traffic to minimize the use of the friction brakes. This will increase your efficiency and extend the life of your brake pads.

Pre-condition the cabin of your Taycan while it’s still plugged in. This allows you to heat or cool the interior using grid power rather than draining the battery, preserving range especially in extreme weather conditions. The Porsche Connect app makes this easy.

Check your tire pressure regularly. Properly inflated tires reduce rolling resistance and improve overall efficiency. Refer to the sticker on your driver’s side doorjamb for the recommended tire pressure for your Taycan 4S.

Minimize the use of auxiliary systems like the climate control. While comfort is important, remember that these systems draw power from the battery and reduce range. Consider using seat heaters and ventilation instead of relying solely on the HVAC system.

Plan your routes carefully, especially on long trips. Use navigation systems that account for charging station locations and availability. This ensures you can complete your journey with minimal delays. Remember you can find all Porsche fuel economy data and TAYCAN MPG across all years here at FuelEconomyHub.com.
