The Infiniti Q50 ticks all the right boxes for those looking for a classy, intelligent, athletic sports sedan.

The car boasts a sleek exterior of flowing lines based upon the Essence concept car Infiniti debuted four years ago. It features potent engines to match the sleek shape. The Q50 is available with either rear-wheel or all-wheel drive, the base engine is a 3.0L V6, which benefits from twin-turbocharging. In standard tune, it makes 300 horsepower and 295 pound-feet of torque, while the high-output version delivers 400 horsepower and 350 pound-feet. Power is transferred to the wheels via a 7-speed automatic transmission.

The base trim includes speed-sensitive power steering, auto on/off LED headlights with LED fog lights, dual-zone automatic climate control, one-touch up/down windows all around, aluminum appointments, 8-way power driver and passenger seats, a 16-speaker audio system with twin USB ports and steering wheel-mounted controls, Bluetooth hands-free connectivity and dual Infiniti InTouch LCD displays.
