For practically 1 / 4 century, the Lexus RX has loved enviable success prioritizing passenger consolation over behind-the-wheel engagement. Lexus, although, desires to develop the fifth-generation mannequin’s ability set in a dynamic route with the 2023 RX500h F Sport Efficiency.

The RX is the second car within the model’s lineup to bear this not too long ago launched sub-F moniker, the primary of which was the IS500 F Sport Efficiency. Like that sedan, the RX500h distinguishes itself from its lesser kin with a powertrain particular to the F Sport Efficiency.

The RX500h Accelerates Forward

Whereas the rear-wheel-drive IS500 encompasses a burly 472-hp 5.0-liter V-8, the all-wheel-drive RX500h employs a hybrid powertrain that mixes a turbocharged 2.4-liter four-cylinder engine and a pair of electrical motors to provide 366 horsepower—91 greater than the RX350 will get from this identical engine performing alone. A nickel-metal-hydride battery pack lives beneath the rear seat and sends electrical energy to the 2 motors, considered one of which Lexus sandwiches between the RX500h’s engine and six-speed automated transmission whereas the opposite immediately powers the rear axle.

The electrical drive motors’ prompt thrust masks any lag from the turbocharger, whereas the fuel engine’s plentiful low-end torque, all of which is offered from 2000 rpm, means the powertrain by no means feels overburdened pushing this 4793-pound SUV about. At its peak, the gas-electric powertrain produces a complete of 406 pound-feet of torque, sufficient grunt to speed up the RX500h to 30 mph in 2.0 seconds and on to the mile-a-minute mark in 5.5 seconds, figures that nearly precisely match these of the 355-hp Acura MDX Sort S.

The Lexus is not any much less keen on the transfer, motoring from 30 to 50 mph in 2.7 seconds and from 50 to 70 mph in 3.7 seconds, its prescient gearbox seemingly hardwired to the accelerator pedal’s place. To place this in perspective, the Lexus SUV’s instances are practically equivalent to these of a 1328-pound lighter, 315-hp Volkswagen Golf R with a seven-speed dual-clutch automated transmission.

Higher but, the RX500h maintains the miserliness anticipated of a hybrid. The gas-electric Lexus matched its 28-mpg EPA freeway estimate on our 75-mph freeway fuel-economy take a look at. That is 5 mpg higher than the aforementioned MDX Sort S. The RX500h additionally has an EPA metropolis estimate of 27 mpg, which is 5 mpg higher than the nonhybrid RX350.

Cannot Cease the RX500h

Lay off the precise pedal, although, and the RX500h’s driving dynamics appear much less spectacular. Even with its new GA-Okay underpinnings—which it shares with the likes of the Toyota Camry and Highlander and Lexus NX, amongst others—the RX500h is neither significantly succesful nor thrilling in any efficiency setting that doesn’t contain booting the accelerator on a straight piece of tarmac.

Goad the RX500h too laborious by way of twisting turns, and the SUV’s heft overwhelms its out there 21-inch Bridgestone Alenza Sport A/S rubber. As its 0.80-g skidpad run displays, the RX500h merely lacks the grip essential to play the a part of a efficiency SUV. Issue within the RX500h’s muted steering suggestions, and it is simple to unwittingly push this Lexus previous its slim limits.

We advise sticking with the usual Michelin Pilot Sport 4 SUV summer season tires, because the stickier compound should noticeably enhance the RX500h’s middling lateral grip and braking efficiency. As is, the RX500h’s 195-foot cease from 70 mph—three ft longer than our 6072-pound long-term Toyota Tundra—borders on unacceptable.

RX for Consolation

Against this, the RX500h hits its stride in on a regular basis driving. Hold its adaptive dampers of their Regular setting, and the RX500h presents a cosseting trip that is nonetheless agency sufficient to maintain extreme physique movement at bay. Switching to the dampers’ Sport mode does little greater than butcher the trip high quality.

The low-effort however direct rack-and-pinion setup consists of an RX500h-exclusive four-wheel-steering system that may flip the rear wheels as much as 4 levels, trimming 1.7 ft from the turning radius. In consequence, this 192.5-inch Lexus has a turning radius higher than the two-foot-shorter Fiat 500X.

The most recent RX presents loads of stretch-out house for 2 passengers in its soft 40/20/40-split rear bench. There’s sufficient shoulder room for 3 passengers to take a seat in cheap consolation on brief jaunts too. Lexus makes the house much more welcoming with out there heated and ventilated outboard rear seats, elective energy reclining rear seatbacks, and an out there panoramic moonroof. The RX500h is not any Rolls-Royce Cullinan or Mercedes-Maybach GLS-class, however like these ultra-luxury machines, its rear seating space is a minimum of as interesting as the driving force’s and entrance passenger’s house.

That is definitely true for these with wider waistlines, given the entrance seats’ confining bolsters. The slim and closely bolstered entrance buckets appear to belong in a car with a lot larger sporting intent. However, these with thin-enough waists will discover the entrance seats present nice long-haul consolation and assist.

The RX inside is properly completed, however we weren’t enamored of the multimode steering-wheel buttons or the infotainment system’s quirks. The latter embrace the shortage of a correct house display and a menu construction that makes sometimes easy duties (similar to switching between the drive modes) needlessly sophisticated.

Surprisingly, Lexus suits its flagship RX trim with the mannequin’s smaller 9.8-inch touchscreen infotainment system. Nabbing the bigger 14.0-inch show, which is included on the cheaper, sub-$60,000 RX350 and RX350h Premium+ and Luxurious trims, provides a minimum of $1105 to the RX500h’s $64,145 beginning worth.

By appending the F Sport Efficiency designation to the RX500h, Lexus appears to be attempting to persuade shoppers that this variant of its bestselling mid-size SUV presents one thing totally different from the sleepy driving dynamics which have lengthy characterised the RX. Actually although, the RX500h continues within the custom of its forebears with its comfy trip, quiet cabin, and spacious lodging whereas including an additional dose of horsepower.
