How many miles per gallon does a 2006 RX400h hybrid get?

The 2006 Lexus RX400h, a hybrid SUV, achieves an impressive fuel economy of 31 miles per gallon (mpg) in the city and 27 mpg on the highway, according to the Environmental Protection Agency (EPA) estimates.


Detailed Fuel Economy Breakdown


The RX400h's fuel efficiency is a result of its hybrid powertrain, which combines a 3.3-liter V6 gasoline engine with an electric motor.

  • City Fuel Economy: 31 mpg

  • Highway Fuel Economy: 27 mpg

  • Combined Fuel Economy: 29 mpg


The RX400h's fuel economy is significantly better than the non-hybrid Lexus RX330, which had an EPA-estimated 18 mpg in the city and 24 mpg on the highway. The hybrid technology in the RX400h allows it to achieve a 30-40% improvement in fuel efficiency compared to the conventional gasoline-powered model.


Factors Affecting Fuel Economy


Several factors can influence the real-world fuel economy of the RX400h, including driving style, terrain, weather conditions, and vehicle maintenance. Aggressive acceleration, high-speed driving, and frequent stops and starts can all reduce the vehicle's fuel efficiency.


Overall, the 2006 Lexus RX400h hybrid SUV offers impressive fuel economy, making it an attractive option for consumers seeking a more environmentally-friendly and fuel-efficient luxury vehicle.
