The G-series has helped to revive Infiniti sales. The latest model continues to build on its success with sleek styling and 3.7L V6 that produces almost 330-bhp. Most models include a 7-speed automatic, but a 6-speed manual is available on the 6MT Sport. Aluminum suspension components and a stiff chassis enhance handling. Technology features include push-button start, adaptive front headlights, rearview monitor, and intelligent cruise control with preview braking. Tough competition from BMW, Lexus, and Audi makes continual improvements to the G37 vital.
