FAULTLESS ride comfort has always been a defining quality of Lexus’ flagship sedan, the LS.
It helped found the brand 30 years ago, and the benchmark set by the original LS has inspired the teams developing each successive LS generation to always seek to do better.
It’s that commitment that has brought about significant advances in the ride quality of the new 2021 LS, achieved not through a single breakthrough in innovation, but through a comprehensive review of the parts.
The result is unprecedented ride comfort, but importantly without sacrificing the car’s rewarding dynamic character.
The fifth-generation LS, introduced in 2018, marked a leap forward in vehicle design, being the first to make use of Lexus’ GA-L (Global Architecture – Luxury) Platform.
The immediate benefits of this underpinning included an excellent chassis balance, a low centre of gravity and much-increased body rigidity.
New multi-link suspension geometry was adopted and the performance of the Adaptive Variable Suspension was revolutionised, moving from a simple nine-stage system to near-seamless, continuous damping control through 650 levels.
LS chief engineer Toshio Asahi explained that they have been implementing improvements year on year to ensure the continual evolution of the LS as a Lexus flagship.
“With the driving performance of the new LS, I decided that we should focus on the ‘refined driving performance’ which forms the model’s DNA and indeed is the starting point for our brand.
“Therefore, we went back to basics and refined the fundamental performance from the ground up.”
The tyres form the single contact point between a car and the road and thus can make an important contribution to ride comfort. The LS will come standard with run-flat tyres, which by their nature are more rigid than conventional tyres.
Lexus has been able to reduce their vertical spring rate to control the up/down movement of the sidewall. Even the tyres’ material compound and inner structure have been adjusted to factor out high-frequency vibrations.
The LS will launch with a few subtle aesthetic changes, both inside and out.
Already launched and sold in some markets, the new model will debut locally during the second quarter of this year.
