Lexus RX Hybrid Engine Options

The 2023 model year introduced all-new Lexus RX Hybrid engines, and their specs were so impressive that the automaker carried them through 2024 and into the 2025 lineup. Each is refined, economical, and surprisingly quiet, given the mighty horsepower and torque they can generate. From the entry-level Lexus RX 350h AWD to the top-spec Lexus RX 500h Black Line Special Edition, this SUV is blazing new, fuel-efficient trails for drivers all across the nation.

The impressive Lexus RX Hybrid MPG values have three culprits – and stunning performance output for each. Here's what to expect from each engine:

      • 2.5-Liter In-Line Four-Cylinder Hybrid Engine: 246 horsepower, 233 pound-feet of torque, and an EPA-estimated 37/34/36 MPG (City/Highway/Combined).1
      • 2.5-liter In-Line Four-Cylinder Plug-In Hybrid Engine: 304 horsepower, an EPA-estimated 83 MPGe (Combined),2 and 37 miles3 of all-electric range.
      • Turbocharged 2.5-liter In-Line Four-Cylinder Hybrid Engine: 366 horsepower, 406 pound-feet of torque, and an EPA-estimated 27/28/27 MPG (City/Highway/Combined)4.

If these stunning specs aren't enough to get your adrenaline pumping, take a look at the two top-quality trims: the Lexus RX 500h F SPORT PERFORMANCE AWD and the Lexus RX 500h Black Line Special Edition. These premium trims live up to their sporty names and use a turbocharged 2.4-liter inline four-cylinder plus the Lexus Hybrid Electric Drive system to churn out 366 horsepower and 406 pound-feet of torque – enough power to jolt you from 0-60 in only 5.9 seconds.

No matter which Lexus RX Hybrid trim you prefer, you'll benefit from standard electronic all-wheel drive that sends instant torque to the rear wheels at a moment's notice. Take home the top-tier Lexus RX Hybrid 500h, and you'll gain an innovative DIRECT4 all-wheel-drive system that monitors every wheel and sends the appropriate torque to each corner to elevate driver confidence. This performance-oriented hybrid SUV also utilizes paddle shifters for on-demand shifting and driver engagement and boasts a 3,500-pound maximum towing capacity when properly equipped.

Lexus RX 350 Hybrid MPG Ratings

Lexus RX 350h Hybrid MPG Ratings

Right from the start, the Lexus RX 350h fuel economy proves that convenience and utility can come together in one package. This entry-level edition – plus the next three trims in the lineup – puts its gas-hybrid system to work to deliver a fuel-savvy EPA-estimated 37/34/36 MPG (City/Highway/Combined).1

Switching gears to the only plug-in hybrid option, the RX 450h+ Luxury touts an impressive MPGe: 83 MPGe (Combined).2

If you're intrigued by the performance that the 2025 Lexus RX Hybrid MPG values provide but want a bit more power at the pedal, consider the Lexus RX 500h F SPORT PERFORMANCE or Lexus RX 500h Black Line Special Edition. With their boosted power and torque figures and ample fuel economy, these top-of-the-line models let you drive home with an economical EPA-estimated 27/28/27 MPG (City/Highway/Combined),4 proving that even this sporty SUV trim can deliver next-level fuel efficiency.

2025 Lexus RX 350h Fuel Type & Tank Size

We know that the new Lexus RX 350 Hybrid MPG impresses in both city and highway driving, but other factors like fuel type and tank size also play an important role in this SUV's performance. The mild-hybrid editions of the new Lexus RX also come equipped with a large 17.2-gallon fuel tank, so you'll make fewer trips to the gas station. The plug-in hybrid RX 450h+ Luxury trim offers a 14.5-gallon tank, leaning more into its electric capabilities.

Across the lineup, every Lexus RX Hybrid model is engineered for peak performance using premium unleaded gasoline. Performance and efficiency could decrease if you're not filling up with premium fuel, so it's best to follow the automaker's guidance of 91 octane or higher to enjoy the full power and benefits of a new Lexus RX Hybrid.

Remember that the Lexus RX 350h hybrid MPG ratings remain the same for the first few styles of this hybrid SUV and that the thrilling Lexus RX 450h+ Luxury and RX 500h models boast stellar fuel economy ratings that rival their non-hybrid competition, so the elevated fuel type is well worth it.
