What is currently known as the Infiniti G37 Sedan began life as the second-generation G35 Sedan back in 2007. Then, back in 2009, the car's 3.5-liter V6 was replaced by a more powerful 3.7-liter unit, resulting in a new name for the car. For those seeking a more affordable sports sedan experience, Infiniti has also recently added the less powerful G25 sedan.
Now, Infiniti has given the G37 Sedan (along with its G37 Coupe and Convertible variants) mid-cycle refresh, including changes to the front and rear fascias as well as to the luxurious interior.
For the latest model the headlights have become more angular and less bulbous than the previous model -- a look that's almost reminiscent of the original G35 coupe lamps. The grille has also been adjusted, and new fog lamp clusters look decidedly well integrated.
The rear bumper was also reworked, though it will take a trained eye to notice the differences. More obvious is the new 17-inch wheel design, which is standard.
Stepping inside will reveal new gauges with a white back theme, which can be complimented by your choice or a new aluminum finish, or a maple trim. The center console and dash also received some stylization changes, and the seven-inch touch-screen now gives users access to real-time traffic and weather via XM satellite.
The G37's 3.7-liter V6 produces 328 horsepower at 7,000 rpm and 269 pound-feet of torque at 5,200 rpm. Rear-wheel-drive is standard, while all-wheel-drive can be had by opting for the G37x model. A seven-speed automatic is the sole gearbox for all G37s save the G37 Sport, which is fitted with a six-speed manual.
Fuel economy is rated at 19 mpg in the city and 27 highway for all rear-wheel drive models equipped with the automatic, while the six-speed manual returns 17/25 mpg. The G37x is good for 18/25 mpg.
The G37's second generation FM ("front mid-ship") platform features a four-wheel independent suspension system with lightweight aluminum components and improved body stiffness.
Available advanced technologies include RearView Monitor, a touch screen navigation system with available real-time traffic and the audiophile-quality Infiniti Studio on Wheels by Bose, combining the industry's first three-way front door speaker array using 10-inch woofers with an audiophile quality head unit incorporating a 24-bit Burr Brown Digital Audio Converter.
Comfort and convenience features include standard Intelligent Key with Push Button Ignition, available Adaptive Front lighting System (AFS), wood trim and Intelligent Cruise Control with Preview Braking.
Those looking for a well-rounded sports sedan like the G37 should also consider the slightly larger Cadillac CTS, the agile Lexus IS 350, the fine-handling BMW 335i and the all-wheel-drive Audi S4.
