20 MPG combined is what you can expect if you want the performance and prestige of the 2021 Porsche Macan S with its 3.0L six-cylinder engine. This isn’t a vehicle aimed at hypermilers. Macan S buyers prioritize driving experience, exclusivity, and the Porsche badge. Lower fuel costs are a secondary concern, but understanding its implications remains important.

City and highway performance

The EPA estimates the 2021 Macan S will achieve 18 MPG in city driving and 24 MPG on the highway. This split reflects the vehicle’s character. In urban environments, the Macan S’s responsive throttle and willingness to accelerate contribute to lower efficiency. Stop-and-go traffic, frequent red lights, and the temptation to exploit the engine’s power all take their toll. On the open road, however, at a steady cruise, the efficient seven-speed dual-clutch transmission (AM-S7) helps the engine settle into a more economical range. The Macan S becomes surprisingly relaxed and refined at highway speeds, delivering its best fuel economy in these conditions.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2021 Porsche Macan S will be $2,900. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices at the time of calculation. Individual fuel costs will vary depending on driving habits, location, and fluctuations in gas prices. However, $2,900 provides a reasonable benchmark for budgeting purposes. The Macan S requires premium fuel, which contributes to the higher annual cost.

Real-world expectations

While the EPA estimates are a valuable starting point, real-world MPG for the Macan S often differs. Aggressive driving, frequent short trips, and extended idling can all reduce fuel economy below the official figures. Alternatively, drivers who prioritize smooth acceleration, anticipate traffic flow, and spend more time on the highway may see numbers closer to or even slightly above the EPA estimates.

Factors like ambient temperature, tire pressure, and even the use of accessories such as air conditioning can also impact fuel consumption. Expect a range, and understand driving style plays a major role.

How it compares

The Macan S exists in a competitive segment, and understanding its fuel economy relative to rivals is critical. The BMW X3 M40i, also powered by a six-cylinder engine, achieves a slightly better combined rating of 23 MPG. The Audi SQ5, sharing a similar engine configuration to the Macan S due to corporate ties, mirrors the Macan’s 20 MPG combined. A more fuel-conscious alternative is the Lexus RX 350, with its 23 MPG combined figure, although it offers a significantly different driving experience that many Macan S buyers would find lacking.

While some competitors offer marginally better fuel economy, the Macan S counters with its superior driving dynamics and a more engaging experience behind the wheel. The target buyer accepts a slight efficiency penalty for the performance and prestige benefits. Comparing all Porsche fuel economy data can also shed light on efficiency within the brand.

Tips to maximize efficiency

Minimize aggressive acceleration and braking. The Macan S’s powerful engine is tempting to exploit, but doing so will quickly deplete the fuel tank. Smooth, gradual acceleration will improve fuel economy and enhance the overall driving experience.

Maintain proper tire inflation. Check your tire pressures regularly and ensure they are inflated to the recommended levels. Under-inflated tires increase rolling resistance and reduce fuel efficiency. Consult the sticker on the driver’s side doorjamb for the correct pressures.

Use the automatic start/stop feature wisely. While it can be slightly intrusive in certain situations, the auto start/stop system can save fuel by turning off the engine when the vehicle is stationary. Become familiar with its operation and learn how to anticipate its engagement to minimize any disruption to your driving.

Opt for the ECO driving mode when appropriate. The Macan S typically has selectable drive modes. When maximum performance is not required, selecting the ECO mode will optimize engine and transmission settings for fuel efficiency. This will dampen throttle response and encourage earlier upshifts, leading to improved MPG.

Reduce unnecessary weight. Carrying excess cargo in the vehicle increases fuel consumption. Remove any items that are not essential for your daily commute or planned trips. Lighter is always better when it comes to fuel economy.
