London, 11 August, 2023, (Oilandgaspress) For 2024, the RX builds on the extraordinary refinement introduced on the fifth generation RX in 2023. Based on customer feedback, the 2024 RX enhances the available technology and convenience features to optimize the driving and in-cabin experience. The much-anticipated 2024 RX 450h+ Plugin Hybrid Electric Vehicle is added to round out the electrified lineup.
For 2024, Cloudburst Gray is added as an available exterior color on all grades and Copper Crest is now available on Premium and F SPORT Handling grades.
The 2024 RX rides atop the GA-K platform, which was designed to be lighter than the fourth-generation platform. It has a low center of gravity thanks to its use of stronger metals (such as 1180 MPa steel on side rockers, 1470 MPa steel for the roof, and 2GPa steel for B-pillars) and innovative adhesives and welds.
Bracing at the radiator support, center floor, rear suspension towers, and back door opening contribute to overall rigidity. The 2024 RX measures at 192.5 inches long, with a wheelbase of 112.2 inches and a track width of 65 inches in front, and 66 inches in the rear. The rear section of the platform features a multi-link suspension design, attached to a rigid high-torsion rear body frame that facilitates consistent suspension input/travel during acceleration, deceleration and steering moments.
The GA-K platform provides ample legroom for rear passengers. RX guests will also enjoy generous cargo space and a low back door trim to decrease loading height.
A Powertrain for Everyone
The 275-hp turbocharged four-cylinder gasoline engine realizes 317 lb.-ft. of torque and high output thanks to several advanced technologies like a center injection system (for more stable combustion), lightweight, spherical lipless pistons (for high-speed combustion), and a continuously variable capacity oil pump (to modify discharge volume based on running conditions). A short-ratio eight-speed Direct Shift-8AT offers a shift control program that provides smooth acceleration and deceleration. The electronically controlled full-time AWD constantly varies the front-to-rear driving force distribution from 75:25 to 50:50 (depending on situation) to achieve an optimal contact patch and linear steering feel.
A hybrid motor coupled with a 2.5-liter four-cylinder Atkinson-cycle gasoline engine with 246 total system horsepower and 233 lb.-ft. of torque is teamed with a high-output, low-resistance nickel-metal hydride battery that offers a high level of output and fuel economy. The 216-cell battery is located below the rear seat, thus enabling passenger comfort and providing storage capacity. RX HEV can be equipped with E-Four, Lexus’ innovative all-wheel drive system which places a motor at the rear axle for near-instantaneous drive force application in low-grip or acceleration scenarios.
Powered by a high-capacity lithium-ion battery paired with a 2.5-liter inline 4-cylinder engine (shared with NX), the 2024 RX 450h+ hybrid system has a manufacturer-estimated combined 83 MPGe rating. The system provides luxury performance and consistent acceleration off the line with an estimated 6.2 second 0-60 time. The RX 450h+ has an EPA-estimated 35-mile driving range rating on electric power only.
The RX450h+ comes equipped with a Level 1 vehicle-charging cable for 120V outlets and all models are equipped with a J1772 (Type 1) socket for at-home and public charging. A high-output, high-efficiency system designed to reduce power loss when converting from AC power to DC power results in faster charging times. Using the maximum charging current of 240V and under ideal conditions, the Lexus RX 450h+ can be fully charged in approximately two-and-a-half hours with the standard 6.6 kW Onboard Charger.
The RX 450h+ utilizes an electronically controlled, full-time AWD system for a confident, sporty driving experience, led by Lexus Driving Signature vehicle fundamentals. Optimizing front and rear torque distribution according to the driving conditions, the driver can control the vehicle as preferred throughout varied road conditions and driving styles.
RX 500h F SPORT Performance AWD
A next level of dynamism is realized by the high-performance hybrid 271-hp 2.4-liter turbocharged inline-four that’s matched to a six-speed automatic gearbox and integrated Power Control Unit and electric motor. At the rear, an 80-kW eAxle consisting of an inverter and motor provides near-instantaneous power to the rear wheels. Together with a high-output, low-resistance nickel-metal hydride battery, the system produces 366 hp and 406 lb.-ft. of torque total. A DIRECT4 all-wheel drive system orchestrates a seamless, direct application of drive force between the front and rear axles in milliseconds, thus improving handling, controllability, and feel. Body movement is also minimized for more pleasant ride comfort.
