Is the Lexus LS fuel efficient?
The Lexus LS, the flagship luxury sedan from Toyota's premium brand, is not known for its exceptional fuel efficiency. While the LS offers a comfortable and refined driving experience, its large size and powerful engines come at the cost of lower gas mileage compared to more compact and efficient vehicles.
Fuel Economy Ratings for the Lexus LS
According to the U.S. Environmental Protection Agency (EPA), the 2023 Lexus LS 500 with rear-wheel drive has an estimated fuel economy of 18 miles per gallon (mpg) in the city, 27 mpg on the highway, and 21 mpg combined. The all-wheel drive version of the LS 500 has slightly lower ratings, with 17 mpg in the city, 25 mpg on the highway, and 20 mpg combined.
These fuel economy figures are on the lower end compared to other luxury sedans in the same class. For example, the 2023 BMW 7 Series with a turbocharged six-cylinder engine has an EPA-estimated 21 mpg city, 29 mpg highway, and 24 mpg combined. The 2023 Mercedes-Benz S-Class with a six-cylinder engine has ratings of 20 mpg city, 30 mpg highway, and 24 mpg combined.
Factors Affecting the Lexus LS's Fuel Efficiency
The Lexus LS's lower fuel efficiency can be attributed to several factors:
- Large Engine Size: The LS 500 is powered by a 3.5-liter twin-turbocharged V6 engine, which produces 416 horsepower. Larger engines typically consume more fuel than smaller, more efficient powertrains.
- Heavy Weight: The Lexus LS is a large, heavy luxury sedan, weighing over 4,700 pounds. Heavier vehicles require more energy to accelerate and maintain speed, resulting in lower fuel economy.
- Luxury Features: The LS is equipped with a host of luxury features and amenities, such as a premium audio system, climate-controlled seats, and advanced safety technologies. These features add weight and complexity to the vehicle, which can impact fuel efficiency.
While the Lexus LS may not be the most fuel-efficient luxury sedan on the market, its powerful engine, smooth ride, and extensive list of features make it a compelling choice for those who prioritize comfort and performance over maximum fuel economy.
