Real-world mileage and factors
In everyday use, drivers may see a range of MPG depending on several variables. The most influential factors include:

- Urban vs. highway mix: Frequent stops and short trips lower MPG compared with steady highway cruising.
- Maintenance and condition: Proper tire inflation, timely tune-ups, and clean air filters help sustain efficiency.
- Fuel compatibility: The engine is designed for premium gasoline, and using lower-octane fuel can affect performance and efficiency.
In practical terms, real-world combined mileage often falls roughly in the mid-teens to low-20s mpg, with higher values more common on long highway trips and well-maintained vehicles.
