The 2018 LS Hybrid takes an entirely different approach than the previous model. The new Multi Stage Hybrid System combines a naturally aspirated Atkinson-cycle 3.5-liter V6 gasoline engine with two electric motor/generators and uses a compact, lightweight lithium-ion battery. The new system is based on the electronically controlled planetary continuously variable transmission of Lexus Hybrid Synergy Drive coupled to an all-new four-speed automatic gear set at the output stage. The two systems work together to expand the overall range of gearing and increase operation of the V6 engine across a wider speed range than previous hybrids. In M mode, the two gear sets are controlled together to provide the effect of 10 ratios, giving the LS 500h a highly engaging drive.
