"The 2014 Infiniti Q50S is probably one of the best non-turbo sport sedans in its segment. As an everyday driver, it makes a pleasurable responsive ride.the 3.7 litre V6 is more than enough to get around town quickly. The bigger Akebono sport brakes make even for more of an agile ride. The interior and entertainment system are definitely top tier in technology and function. The choice of materials to style the interior have improved over past G models..Downside in this regard is that the entertainment system does take an extra few moments to "boot up," after starting the ignition. The developers might wanna tweak this issue in future models. Once its up and running however, great function.The 19inch run flats that come standard on the Q50S are "temperamental" in city driving so special care must be taken around potholes. Overall a great car. I'll have to emphasize getting a Q50 that's well equipped. I recommend an S personally."
