Three different powertrains are available in the 2023 Lexus RX, ranging from the conservative to the high-performance. At the base level, the 275-horsepower turbocharged 2.5-liter four-cylinder engine is perfectly fine for most drivers. Its got power on demand and firm acceleration thanks to 317 lb-ft of torque running through the eight-speed automatic transmission. Front-wheel drive is standard, with all-wheel drive available. Front-wheel drive versions get 22 MPG city and 29 MPG highway, while all-wheel drive models drop both by 1 MPG.

Drivers looking for efficiency and a lower fuel bill will love the hybrid RX350h, which pairs electric motors with a 2.4-liter four-cylinder engine. These combine for 246 horsepower, which runs through a continuously variable automatic transmission (CVT) to standard all-wheel drive. The electric motor helps the RX get off the line quicker, while also improving fuel economy to 37 MPG city and 34 MPG on the highway.

The unique powertrain in the RX500h puts a turbocharger on that 2.4-liter engine while keeping the electric motors. This creates 366 horsepower and 406 lb-ft of torque, going to the ground through a six-speed automatic transmission with paddle shifters and the advanced DIRECT4 all-wheel drive system. All of this chops 1.5 seconds off the acceleration time of the base model – the RX500h can do 0-60 MPH in only 5.9 seconds! Despite this performance upgrade, the 500h gets solid economy, at 27 MPG city and 28 MPG highway.
