The New Lexus RZ It presents itself on the market Italian After the European presentation, also some More detail. Il Restyling of the electric SUV of the Japanese car manufacturer introduces various innovations that are mainly concerned Technology and engines. To see him on Straba, however, we will have to wait a little longer, since the The commercial launch is expected by the end of the year. The most important changes that Lexus introduced with the update of his electric SUV? Power is growing one improve autonomy And loading times. As we had already seen, two important innovations will also arrive, namely the system Steering-per-wire and the simulated gearbox. Lexus has also improved on the driving dynamics thanks to a greater stiffness of the structure, a development of the suspensions and the evolution of the Direct4 All -Wel Drive system.
More power and autonomy
Powertrain has been completely revised. The most important changes include the introduction of a new lithium battery with high capacity and electric axles, with an electric engine power and improved items efficiency. There is also one New 22 kW integrated charger. The restyling was introduced New 77 kWh battery. The structure of the battery cells has been revised and their number has been increased to make more power through the Eaxle possible. This result was achieved without changing the external dimensions of the package, which are therefore completely placed under the platform of the vehicle. For the new battery The liquid cooling system has also been revised. The operating elements of the cooling system are efficiently coordinated with the air conditioning system, so that sources of cooling agent or radiator are used, according to the external temperature. The radiator is placed in close contact with the battery and cools off from the bottom to obtain efficient and uniform performance.
New Lexus RZ will be available in 3 different versions. Let’s start with RZ 350E Voorste -Wiel Drive with 224 hp / 165 kW. The autonomy reaches 568 km WLTP and in the field of performance, to go from 0 to 100 km/h, you need 7.5 seconds, while the maximum speed reaches 160 km/h. Then there is the RZ 500E with all wheheel drive con Double motor EN 381CV / 280 KW. From 0 to 100 km/h in 4.6 seconds and maximum speed of 180 km/h. Autonomy is 500 km. For those who want the maximum in terms of performance, there is the version RZ 550E with all wheel drive with double motor and 408 hp / 300 kW. From 0 to 100 km/h in 4.4 seconds and maximum speed of 180 km/h. Autonomy drops to 450 km.
To improve the loading times in cold climates, the new RZ is equipped with a New battery pre -contracting system. It can be operated manually, via an assignment in the multimedia system, or automatically when a charging point is set as a reference point or destination of the path in the navigation system. You can also use a timer to program the heating for a specific trip.
Best driving dynamics
Interventions on the frame and on the structure to improve the driving dynamics of the new Lexus RZ. There The structural stiffness has been raised With improvements in the field of support of the front radiator: greater thickness of the plate and reinforced joints. Moreover, the addition of a rear reinforcement contributes to reducing localized torsion -distortion. These precautions prefer a clean and linear response to the steering inputs.
These precautions prefer a clean and linear response to the steering inputs. The support of the steering cabinet is also regulated to make the system more rigid and more reactive. Lexus also has Review the Direct4 System To improve stability and traction Versions with all wheheel drive. The intelligent system automatically controls the distribution of the torque between the front and rear EAXL, based on the driving conditions and the inputs of the driver. The distribution interval of the pair has been extended, so that in the beginning and in acceleration in straight, the front/rear distribution is arranged between 60:40 and 0: 100, which means that the pitch is eliminated and a sensation of direct gear is guaranteed. For turns, the distribution ratio is optimized between 80:20 and 0: 100, based on the speed of the vehicle and the steering angle, to adapt to the driving conditions.
Send by wire
One of the most important news of the Lexus RZ Restyling is the introduction of the Send by wire. The new system differs a lot from a conventional steering system For the absence of mechanical connection between the steering wheel and the front wheels. The driver’s inputs of the driver are in fact broadcast via electrical signals from a few actuator to a control actuator. With a conventional system, the driver may have to perform two or three full rounds of the steering wheel to go from one end of the other. With the new Lexus system, a rotation of 200 degrees of the new steering wheel is sufficient to go from the neutral position to full fulfillment to the left or right, so that the movements of “Pass-Man” or crossed arms are almost completely eliminated. Although there is no physical connection between the steering wheel and the wheels, the driver enjoys a precise and rewarding steering feedback, sent by electrical signals, with unpleasant filtered vibrations. Safety is insured thanks to a complete redundancy system in which every component is duplicated. There is also an extra spare feed.
Simulated gearbox
Only on the new RZ 550E F Sport will it be possible to have the new one Lexus Interactive Manual Drive. Simplifying, it is a system with which you can simulate traditional gear changes. Thanks to the paddles behind the wheel, the driver can manage the driving force directly by selecting virtual relationships, creating a more direct and satisfying bond with the car. The system is easily activated via the “M mode” button placed on the central tunnel. The assignment can also be used in combination with the selection of the driving mode. When the sports mode is selected, the acceleration is more reactive on the accelerator inputs than normal mode.
