VIDEO:2021 Lexus LS 500h and LS 500 Engines Explained BY DPCCAR. The 3.5-liter, twin-turbo V6 engine on the LS 500 offers the output one would expect in a flagship sedan: 416 horsepower and 442 lb-ft of torque. In the pursuit of refinement goals, the engine features a newly developed piston with a lip shape on the piston top to help realize low emissions and quiet operation when the engine is cold. The wastegate control on the twin-turbo engine has also been updated to provide stable opening and closing of the valve to improve performance efficiency.

The 10-speed automatic transmission also receives attention, as its shift logic is re-calibrated to aid in keeping the engine in a more responsive area of its power band. In RWD form, the LS 500 delivers a 0-60 time of 4.6 seconds. The driver can tailor powertrain response and feel by choosing from Eco, Comfort, Normal, Custom, Sport S or Sport S+ modes. The available AWD system features a TorsenĀ® limited-slip center differential to further enhance grip, traction and cornering stability. The torque distribution can vary from 31 percent front / 69 percent rear on dry roads to as much as 48 percent front / 52 percent rear on slick surfaces.
