Factors that influence real-world fuel economy
Several practical factors can push mpg above or below the EPA estimates. The IS 300’s turbocharged engine rewards smooth, consistent highway cruising, and it’s sensitive to load and tires.
- City vs. highway driving: Frequent idling, stop-and-go traffic lowers city mpg more than highway mpg.
- Tire pressure and tires: Underinflated tires reduce efficiency; low-rolling-resistance tires help.
- Weight and aerodynamics: Roof racks and heavy cargo increase drag and reduce mpg.
- Maintenance and fuel quality: Regular maintenance and using the recommended fuel grade support efficiency.
In practice, consumers may see a range around the EPA estimates depending on conditions and driving habits.

Fuel economy is a key factor for buyers choosing between the IS 300 and rivals in the entry-luxury segment. The 2024 IS 300’s efficiency, while not class-leading, offers a reasonable balance of performance and efficiency for its turbocharged powertrain.
