The Minor Change Effectively Enhanced Its Strengths — A Test Drive of the New Lexus LS500h | LEXUS
Focus of the Minor Change: Improved Ride Comfort and Quietness
Upon test driving the "F Sport" and "Version L" trims of the hybrid "LS500h," which combines a 3.5-liter V6 engine with an electric motor, the improvements were even more apparent. It truly felt as though its strengths had been skillfully enhanced.
While cars are manufactured products of metal, they possess surprisingly human qualities. Many aspects are adjusted by human hands, much like a piano. Consequently, the intentions of the creators are vividly reflected in the driving experience.
To share a bit of behind-the-scenes insight, the minor change to the LS was driven by the vision of Koji Sato, who became President of Lexus International in 2019 and has a background in engineering. President Sato promotes a car manufacturing philosophy centered on the forward-looking slogan "Always On," which is sometimes seen in reports from international corporations. This philosophy emphasizes the importance of continuously evolving and adapting, rather than remaining static.
The LS's suspension system was refined in 2019, and further enhancements were made this time. Yuichi Iwata, Chief Engineer of Product Planning, explained, "There is no ultimate goal." The primary objectives of this minor change were to improve ride comfort and quietness. Damper settings have been altered, and the tires have been re-evaluated. While continuing with run-flat tires, meticulous attention was paid to aspects contributing to ride comfort, such as optimizing the vertical flexibility of the sidewalls.
The LS gives the impression of having a well-tuned chassis. At low speeds, it absorbs road imperfections with remarkable finesse, ensuring a smooth ride for occupants and maintaining a stable line of sight for the driver, crucial for confident driving.
"Initial response is important. Equally important is how the car's body is controlled. We refined the settings with the idea of enabling the driver and car to 'converse,'" says Yoshiteru Ito, Chief Expert at the Product Experiment Department of Lexus International.
When turning the steering wheel through a curve, the car body rolls gently. In other words, the driver can perceive the process of the car's movement. Mercedes-Benz and Porsche excel at this among European manufacturers, and the Lexus is now achieving a similar level of refinement.
