All-New Lexus LS 500h to Feature Multi Stage Hybrid System
Lexus’ new LS 500h flagship sedan 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 new LS 500h will make its world debut at the Geneva Motor Show on 7 March.
The system, first installed in the powertrain of the new LC 500h luxury coupe, brings multiple benefits in terms of improved throttle responsiveness, high-speed cruising at lower engine rpm and the ability to cruise at higher speeds, with the petrol engine shut off – up to 140km/h.
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 LS 500h’s Lexus Hybrid Drive powertrain, which features a 3.5-litre V6 Dual VVT-i petrol engine and two electric motors. The result is more direct response to driver throttle inputs – a quality that is particularly noticeable when pulling away from stationary.
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 LS 500, with a linear, direct and continuous acceleration feel, making for a more rewarding driving experience.
