Infiniti replaced its old 3.5-liter V-6 with a new 3.7-liter V-6 last year, subsequently changing the model name from G35 to G37. In the sedan, this engine makes 328 horsepower while delivering a little over 20 mpg in our testing.

The G37 can be had in sedan or coupe configurations. The coupe has a steep roof drop-off, compromising rear seat space, while the sedan seats five easily.

The ride quality is reasonable in the G37 Sedan, leaning a little more toward sport than luxury. In cornering, the G37 keeps body roll to a minimum.

Column-mounted paddle shifters let you select gears in manual mode. We found downshifts reasonable fast, but upshifts lagged a bit.
