Lexus RX450h replaced the hybrid version of the previous generation RX400h. The car received an updated hybrid installation and has become even more advanced in technical and environmental terms. The RX450h is equipped with a proprietary Lexus Hybrid Drive hybrid system, which is paired with the E-Four electric all-wheel drive system. A 3.5-liter V6 is part of the power plant - for the first time on Lexus models, it runs on the Atkinson cycle. The RX450h transmission is a continuously variable variator. Crossover Lexus RX450h combines the best qualities of a sports sedan and SUV. The luxurious Lexus RX is equipped with modern information systems with an intelligently developed interface. The second row of seats is divided into three parts, each of which has a longitudinal adjustment and adjustment of the backrest, which allows the rear passengers to sit with great comfort. Optimization of the internal space was greatly facilitated by the more compact rear suspension on double wishbones, which improved dynamic performance.
In the US market, the car was available in four-wheel drive and front-wheel drive modifications. Equipment levels are similar to what the RX350 offers. Standard equipment includes 18-inch alloy wheels, self-dimming exterior mirrors, an access and start system for the engine without an ignition key, power seats for the first row (10 adjustments), electric power for the steering column (tilt and reach adjustment), wood inserts in the interior decoration , an audio system with nine speakers and a six-disc CD changer, an on-board LCD system. The sports package includes 19-inch wheels and sports suspension. Premium package - leather seats, panoramic sunroof, electric tailgate, driver's seat memory and iPod interface. In addition, the optional equipment includes adaptive xenon headlights, heated and ventilated front seats, a leather interior, navigation system, Mark Levinson audio system, an entertainment complex for rear passengers, etc. d.
The hybrid powerplant combines the power of a gasoline 3.5-liter V6 engine with a return of 248 horsepower and two electric motors, thanks to which they provide very powerful torque even at low revs and a dynamic start. If we talk about the characteristics of these electric motors, the front one has a capacity of 123 kW (167 hp) and has a torque of 335 Nm. Rear - 50 kW (68 hp) of power and torque of 139 Nm. Among the various upgrades, the RX450h received an advanced “EV Mode” movement mode (movement only on an electric motor). The fuel consumption of the new car is 6.3 liters per 100 km, which is much less than the RX350. If other comparisons are given, then the actual return of the RX450h is comparable to a 4.5-liter gasoline engine, and fuel consumption is comparable to the 1.8-liter engine of some sedan. In the design of the chassis, the RX450h does not differ from the RX350 - in front of it is an independent McPherson suspension, two-link in the rear. Used ventilated brake discs for all four wheels and an active electric power steering. Lexus RX450h uses the same design as the RX400h in its transmission design - its hybrid engine drives the front wheels, transmission of traction to the wheels is provided by an electronically controlled automatic E-CVT gearbox, while the power flow is divided into two: one is sent to the wheels , the other on the generator to recharge the battery. In all-wheel drive versions, another electric motor is installed at the rear, which drives the rear wheels. There is no rigid mechanical connection between the two bridges.
In addition to luxury and versatility, this crossover has a rigid body frame, excellent active and passive safety. The basic version includes 12 airbags, including front, side, curtain airbags and both knee airbags. The United States National Security Administration (NHTSA) rated the Lexus RX350's overall safety level as five out of a possible five. In the IIHS test categories, the third RX received the highest rating with a rating of "good".
Hybrid RX450h has its own characteristics in operation and maintenance, but the most serious costs can be associated only with expensive repairs of specific equipment in terms of hybrid technologies. Therefore, before buying, it is better to entrust the choice to a specialist. In the Russian secondary market, used American modifications of the RX450h are represented by a small number, but mainly in the maximum configurations.
