Lexus' new LS500h flagship sedan, which will make its world debut at the Geneva Motor Show on 7th March 2017, is to benefit from the company's Multi Stage Hybrid System - a breakthrough technology that transforms the performance and driver appeal of hybrid power.
The system, first installed in the powertrain of the new LC500h luxury coupe, brings multiple benefits in terms of improved throttle responsiveness, high-speed cruising at lower engine rpms and the ability to cruise at higher speeds of up to 140km/h with the petrol engine shut off.
At the same time, overall fuel efficiency and emissions performance are improved while preserving the smooth, quiet and sophisticated drive that is a hallmark of Lexus hybrids.
The Multi Stage Hybrid System adds a four-stage shift device to the LS500h's Lexus Hybrid Drive powertrain, which features a 3.5-litre V6 Dual VVT-I petrol engine and two electric motors. The result is a more direct response to driver throttle inputs - a quality that is particularly noticeable when pulling away from a standstill.
Although the system comprises a four-stage shift, its operation replicates the feel of driving with a 10-speed transmission - like that featured in the V8-level powered LS500 - with a linear, direct and continuous acceleration feel, making for a more rewarding driving experience.
