Lexus LC 500h gets 354 horsepower, 4-speed gearbox
Lexus has disclosed powertrain details for the LC 500h ahead of the hybrid’s formal debut in Geneva.
Described as a Multi Stage Hybrid System, the setup pairs a 3.5-liter V6 engine and a single electric motor. Notably, a four-speed gearbox is mated to the rear of the hybrid transmission.
“The electric motor generates better acceleration feel than a conventional engine, and adding physical gears more closely aligns engine rpm with the driver’s inputs,” the company notes. “The result is a much more direct connection between the accelerator pedal and vehicle acceleration, and 0-100 km/h (0-62 mph) times well into the sub-5 second range.”
Drivers can also engage an ‘M’ mode for driver-initiated gear shifts, the first such system available on a Lexus full-hybrid powertrain. The system is designed for a sporting and engaging driving experience.
Engineers chose a lightweight and compact electric motor, along with a lithium-ion battery, to offset the extra weight of the four-speed transmission. Consequently, the system is no heavier than Toyota‘s traditional hybrid powertrains.
The V6 produces 295 horsepower and 257 lb-ft of torque, with a total system output of 354 ponies when the electric motor is running at full tilt. The figures appear to fall short of the 470-horsepower rating cited in early reports, though the electric motor’s torque output could be significant.
Additional details could continue to surface before the LC 500h is introduced at the Geneva Motor Show.
