PERFORMANCE
A Lexus hybrid world-first
Lexus Hybrid Drive
The Lexus Hybrid Drive system integrates the 3.5 litre V6 petrol engine with a high torque electric motor. The V6 engine produces a maximum 183kW of power at 6,000rpm and 317Nm of torque at 4,800rpm, while the front electric drive motor delivers 123kW with 335Nm of instantaneous torque.
In addition, the RX 450h has a 50kW electric motor to power the rear wheels via Lexus' unique Electronic Four Wheel Drive system. Any spare energy that can't be immediately used is stored as electricity in a compact 288 volt Nickel Metal Hydride battery.
The power of E-Four
The unique Electronic Four Wheel Drive (E-Four) system on the RX
450h's rear wheels contributes to the excellent energy efficiency
and performance of the Lexus Hybrid Drive system. E-Four saves fuel by only
using All Wheel Drive when it is needed. E-Four drives the rear
wheels during take-off, acceleration and low-speed cornering.
When traction is required during acceleration, tight cornering
and marginal driving conditions, E-Four adjusts the distribution
of torque to ensure stable driving performance, working in
conjunction with the RX 450h's Vehicle Dynamics Integrated Management
system.
Regenerative braking
Impressive suspension
The unique trailing-arm type double-wishbone rear suspension provides exceptional agility and control, while fully independent MacPherson strut front suspension further enhances handling and ride comfort.
Electronic continuously variable transmission
The Lexus Hybrid Drive system in the RX 450h includes clutchless Electronic Continuously Variable Transmission (ECVT), which ensures incredibly smooth acceleration without the interruption of gear changes. By adapting to driver input and driving conditions, ECVT ensures the engine continuously operates at peak efficiency for improved fuel economy.
Adopt an energy-efficient driving style
The RX 450h includes technology designed to help you adopt a more efficient driving style. Place the vehicle in ECO mode and it will automatically adjust the air conditioning and responsiveness of the accelerator to improve the vehicle's efficiency. In EV mode, the RX 450h has the ability to travel up to two kilometres at low speeds on electric power alone, using no fuel and emitting no CO2. Often, when you're not accelerating, the petrol engine will not be running2.
Superb handling and control
Adroitly engineered systems that add to the exceptional level of drive performance and fuel efficiency in the RX 450h include road speed-sensitive Electric Power Steering (EPS), which ensures no power is wasted by engaging only when it is required. EPS forms part of the Vehicle Dynamics Integrated Management system and helps correct oversteer and understeer.
In addition, you'll experience outstanding vehicle control with the electro-hydraulic braking system, which controls each brake independently. This provides more precise brake force distribution and closer cooperation with related safety systems.
