Lexus is renewing its LS by introducing a less conservative fifth generation whose dimensions are superior to the previous model. The front and rear ends are true to Lexus' signature design. Inside, opulence reigns with leather seats and sumptuous materials. The LS 500 trades the old model’s V8 for a 416-horsepower, twin-turbo V6 and a 10-speed automatic gearbox. The LS 500h hybrid delivers a combined 354 horsepower via the V6 engine and an electric motor.
