Is Lexus IS 300 fuel efficient?

The Lexus IS 300 is a compact luxury sedan that offers a balance of performance and fuel efficiency. While it may not be the most fuel-efficient vehicle in its class, the IS 300 still delivers respectable gas mileage for a car in its segment.


Fuel Economy Ratings for the Lexus IS 300


According to the U.S. Environmental Protection Agency (EPA), the 2023 Lexus IS 300 with rear-wheel drive has an estimated fuel economy of 21 miles per gallon (mpg) in the city, 31 mpg on the highway, and 25 mpg combined. The all-wheel drive version of the IS 300 has slightly lower ratings, with 20 mpg in the city, 28 mpg on the highway, and 23 mpg combined.


These fuel economy figures are about average for a compact luxury sedan. In comparison, the BMW 3 Series, a key competitor to the IS 300, has EPA ratings of 26 mpg city, 36 mpg highway, and 30 mpg combined for the base model. So the Lexus IS 300 trails the BMW 3 Series in terms of overall fuel efficiency.


Factors Affecting the IS 300's Fuel Efficiency


The Lexus IS 300's fuel economy is influenced by several factors, including its powertrain, weight, and driving conditions:



  • Powertrain: The IS 300 is available with a 2.0-liter turbocharged four-cylinder engine that produces 241 horsepower. This engine is paired with an eight-speed automatic transmission.

  • Weight: As a compact luxury sedan, the IS 300 weighs between 3,649 and 3,737 pounds, depending on the drivetrain configuration. Heavier vehicles generally have lower fuel efficiency.

  • Driving Conditions: Like any vehicle, the IS 300's fuel economy can vary depending on factors such as driving style, traffic conditions, and weather. More aggressive acceleration and higher speeds will result in lower fuel efficiency.


It's worth noting that the IS 300's fuel economy figures are on par with other compact luxury sedans in its class. While it may not be the most fuel-efficient option, the Lexus IS 300 still delivers respectable gas mileage for a vehicle in its segment.
