GENEVA: The Geneva Motor Show hosts the world debut of the new Lexus LS 500h, the full hybrid version of Lexus’ new flagship sedan.
The LS 500h’s Lexus Multi Stage Hybrid System combines a 3.5-litre V6 Dual VVT-i petrol engine with two electric motors, together delivering a total output of 354 hp.
The engine makes optimal use of Dual VVT-i (intelligent variable valve-timing), while D-4S direct fuel injection helps create optimum combustion conditions.
The car’s design successfully brings together the virtues of a long-wheelbase four-door sedan with a low, coupe-like profile
The LS 500h is equipped with the new Lexus Multi Stage Hybrid System, which adds a four-stage shifting device to the Lexus Hybrid Drive combination of a 3.5-litre V6 petrol engine and two electric motors.
In a conventional full hybrid vehicle, engine output is boosted by the electric motor via a reduction gear, but with the new Multi Stage Hybrid System the power from the V6 engine and the hybrid battery can be amplified by the four-stage shifting device, allowing much greater drive power to be generated when accelerating from stationary and achieving a 0-100 km/h acceleration in 5.4 seconds.
High-speed cruising can be enjoyed at lower engine rpm and the LS 500h is able to run at higher speeds―up to 140 km/h―with the petrol engine shut off.
In the 10th gear range, the CVT control allows for high-speed cruising at lower engine revs for quiet, smooth and fuel-efficient performance.
Thanks to the Multi Stage Hybrid System’s design, the driver is able 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.
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).
The LS 500h is built on the new Lexus Global Architecture―Luxury (GA-L) platform, which ensures a low centre of gravity and optimum weight distribution.
The GA-L platform is the stiffest Lexus has yet created, for improving handling, ride smoothness and cabin quietness.
The design of the GA-L platform allows the car’s centre of gravity to be made lower, with most of the mass, including the engine and passengers, moved to a more central and lower position in the chassis.
The LS 500h features the world’s first intuitive pedestrian detection function with active steering.
If a pedestrian is detected on the road ahead and a collision is imminent, this system will automatically apply the car’s brakes and steer around the person, while keeping to its traffic lane.
The driver will be alerted to the system’s operation by a warning on the colour head-up display.
The car is equipped with up to 14 airbags.
Lexus CoDrive, a high-level driving support system, is also being introduced in the new LS.
This provides steering control in accordance with the driver’s intention and continuous driving support on motorways.
Omotenashi, expressing the unique sense of Japanese hospitality, defines the LS 500h’s whisper-quiet and luxurious interior.
There is also an optional rear seat arrangement that includes an extending leg ottoman and the most generous leg room of any LS generation.
Notably, the new LS 500h is longer even than the current long wheelbase LS.
The wheelbase increased from 3,090mm to 3,125mm.
Lexus Takumi craftsmanship also contributes to the special quality of the LS 500h’s cabin, in luxurious new trims, materials and detailing, including a new pleating treatment and Kiriko glasswork on the inner door panels.
