Infiniti Q50

The Q50 is a competitive luxury sports sedan, available in rear- and all-wheel-drive configurations. The standard 300-hp, turbocharged V6 engine costs about what most competitors charge for a turbocharged four-cylinder. That punchy engine combined with the standard seven-speed automatic transmission, makes the Q50 quick but to the detriment of fuel economy, which is 22 mpg overall. Handling is quite nimble, and the ride is compliant. The cabin and backseat are relatively roomy, but the trunk is small, even for this class. Infiniti's touch-screen infotainment system is very cumbersome to use, requiring multiple steps and extra distraction for simple tasks. A 400-hp turbo V6 is also available, as is a Q60 coupe version. Forward collision warning and automatic emergency braking are standard.
