World Premiere Of The All-New Lexus Ls 500h – March 07, 2017– Aichi , Japan (Techreleased) – The world debut of the new Lexus LS 500h introduces breakthrough technology that transforms hybrid powertrain performance and driver appeal.
The full hybrid version of the new Lexus flagship sedan, unveiled at the Geneva motor show, presents brave design, exhilarating performance and a sophisticated appeal to capture the imagination of forward-thinking, younger customers.
The LS 500h is equipped with the new Lexus Multi Stage Hybrid System, combining a 3.5-litre dual VVT-i (intelligent variable valve timing) V6 petrol engine with two electric motors, together delivering a total output of 264kW.
Conceived as the new global pinnacle of the Lexus brand, the LS goes beyond what the world expects from a luxury car. Chief Engineer Toshio Asahi explained: “Developing such a flagship model required a massive paradigm shift. Rather than being bound by the conventions that had defined luxury cars in the past, we aimed to create a car with innovative, emotional and sensual appeal that would draw customers’ eyes away from other luxury cars and provide entirely new values.”
The LS 500h’s V6 petrol engine makes optimal use of dual VVT-i with valve timing precisely gauged in line with driving conditions, helping secure high torque at all engine speeds.
Measures to reduce friction losses and thus improve engine efficiency include the adoption of narrow, lightweight roller rocker arms and low-friction timing chains, while D-4S direct fuel injection helps create optimum combustion conditions, contributing to good fuel economy.
The design of the system places the multi-stage shift unit immediately behind the power split device, on an axis aligned with the engine crankshaft. Although the unit has four speeds, the D range has a simulated shift control pattern that delivers the feel of driving with a 10-speed gearbox.
The Multi Stage Hybrid System’s design enables the driver to take advantage of an M mode to select and hold gears manually using paddle shifts mounted behind the steering wheel – a function not previously available on a Lexus hybrid.
Thanks to the co-ordinated control of the power-split device and the gear-shifting mechanism, the gear shift will start instantaneously with the computer receiving the signal from the paddle shift, giving an exceptionally quick response.
Lithium-ion hybrid battery
The LS 500h is fitted with a compact, lightweight, lithium-ion hybrid battery. It is 20-per-cent smaller than the nickel-metal hydride unit featured in the current Lexus LS 600h, yet has a higher power density. It increases the luggage capacity by 25 litres (versus LS 600h).
Lithium-ion technology also results in less weight, helping reduce the car’s mass to support overall fuel economy, emissions performance and handling balance.
The LS 500h is built on the new Lexus Global Architecture – Luxury (GA-L) platform, which made its debut in the LC coupe and now, with a longer wheelbase, underpins the new LS.
The GA-L platform is the stiffest Lexus has yet created, providing a perfect foundation for improving handling, ride smoothness and cabin quietness.
To reduce unspring weight, and thereby promote agility and comfort, aluminium is used extensively in the suspension’s construction.
Adaptive variable suspension, air suspension and the co-ordination of braking, steering and stability systems through Lexus Dynamic Handling all help secure better ride comfort, rear stability and handling.
New advanced safety systems
Advanced technologies are further used to deliver impressive safety performance.
The Lexus Safety System+ combines information from omnidirectional sensors around the vehicle, including stereo cameras, that monitor all operating situations from parking manoeuvres to collision avoidance. It helps prevent accidents happening, covering the risks presented by common types of accidents such as rear-end collisions, collisions with pedestrians and accidents caused by lane departure.
If a pedestrian is detected on the road ahead and a collision is imminent, this system will automatically apply the car’s brakes. The driver will be alerted to the system’s operation by a warning on the colour head-up display.
The robust structure of the LS has been enhanced to provide a high degree of passive safety to protect occupants in a collision, using new bonding technology, lighter high-tensile strength materials and aluminium bumper reinforcement.
Following the “Yet” philosophy that has guided the design thinking for successive generations of the LS, Lexus has created a design that offers the room and comfort of a long-wheelbase prestige sedan, yet with the stylish silhouette of a four-door coupe.
Lexus designers took full advantage of the opportunity provided by the low centre of gravity and optimum weight distribution from the LS’s new GA-L platform to produce a lower profile and a long wheelbase, giving the car a stretched, ground-hugging appearance.
The LS displays a unique rendition of the signature spindle grille, designed to convey an aura of dignity that befits the model’s position at the pinnacle of the Lexus brand. The grille has a mesh texture that appears to change in different light, created through months of intense CAD development and the hand-adjustment of thousands of individual surfaces to gain the optimum effect.
Luxury interior inspired by Japanese hospitality
The LS cabin has benefited from an equally new approach, interpreting Japanese aesthetics and craftsmanship traditions in the context of an advanced, luxurious and innovative vehicle interior. Notably, the LS 500 was honoured at NAIAS with the EyesOn Design Award for excellence in interior design.
The serenity of the cabin provides an ideal stage for the Mark Levinson premium audio system that features a sophisticated “Quantum Logic Immersion” sound tuning technology and ceiling array, creating a 3D surround audio for a concert-like experience.
Lexus Takumi craftsmanship also contributes to the special quality of the LS 500h’s cabin, in luxurious new trims, materials and detailing, including new origami-inspired hand-pleated door trims and hand-crafted designs created by Kiriko artisan glassworkers for the inner door panels.
