2014 Lexus IS 350 F Sport gets a 3.5-liter V6 with D4-S direct and port fuel injection. The 3.5 engine produces 306 hp @ 6,400rpm, 277 lb.-ft. torque @ 4,800rpm. The IS 350 inherits the eight-speed, Sport Direct Shift (SPDS) automatic transmission from the IS F high-performance model.
This transmission features paddle shifters and the G-force Artificial Intelligence (G-AI) system, which automatically selects the optimum gear and downshift pattern in response to G force. Available for both IS models, an electronically controlled all-weather drive system is designed to help enhance traction and grip under all driving conditions by automatically varying front-to-rear torque balance from 50:50 to as much as 30:70.
