Is the Lexus LS fuel-efficient?
The Lexus LS, the flagship luxury sedan from Toyota's premium brand, is not considered a particularly fuel-efficient vehicle. While the LS offers a comfortable and refined driving experience, its large size and powerful engines result in relatively high fuel consumption compared to more compact and efficient luxury sedans.
Lexus LS Fuel Economy Ratings
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 of 17 mpg city, 25 mpg highway, and 20 mpg combined.
These fuel economy figures are on the lower end for a luxury sedan in this class. In comparison, the BMW 7 Series and Mercedes-Benz S-Class, two of the LS's main competitors, have combined fuel economy ratings in the low-to-mid 20s mpg range.
Factors Affecting the Lexus LS's Fuel Efficiency
The Lexus LS's lack of fuel efficiency can be attributed to several factors:
- Large, Powerful Engines: The LS is available with a 3.5-liter twin-turbo V6 engine that produces 416 horsepower. This powerful engine, while providing impressive acceleration, comes at the cost of higher fuel consumption.
- Heavy Curb Weight: The Lexus LS is a large, heavy sedan, with a curb weight ranging from around 4,800 to 5,000 pounds depending on the model. The additional weight requires more energy to move the vehicle, reducing fuel efficiency.
- Luxury Features and Amenities: The Lexus LS is packed with a wide array of luxury features and amenities, such as a premium audio system, heated and cooled seats, and advanced safety technologies. These features add weight and complexity to the vehicle, contributing to its lower fuel economy.
While the Lexus LS may not be the most fuel-efficient luxury sedan on the market, its combination of power, comfort, and premium features still make it a popular choice for those seeking a luxurious and refined driving experience.
