The Infiniti Q50 is one of Infiniti’s most popular rides. Drivers rave about the sport sedan’s beautiful styling and crisp handling. A turbocharged four-cylinder engine increases the sedan’s highway fuel economy to 31 mpg. You can also choose from a pair of turbocharged V-6 engines. The high-performance version develops an aggressive 400 horsepower. Run-flat tires and LED headlamps come standard. As usual, the Infiniti Q50 continues to offer one of the best interiors in its class. A dual-screen display gives the cabin a luxurious character. Safety innovations, such as Intelligent Cruise Control, make it an extremely secure sports sedan.
