Performance has always been an Infiniti trait. Throttle response is instant, whether you're moving away from a stoplight, making a tight freeway merge or passing.This V8 is among the smoothest and most satisfying around today, easily holding its own with the Lexus and BMW offerings and perhaps even a touch smoother and quieter than the Mercedes-Benz V8s. The Q45 has always been more of a driver's car than the LS 400 and that tradition continues. The engine and transmission are connected electronically; smooth, precise shifts are based on speed and load. On the road, the feeling is of a seamless flow of power with no hesitation or jerkiness between shifts.
This car always feels firmly planted. It's stable as a train in a straight line, controlled in turns.
