2012 Infiniti G37 Review

Notable alternative to the 3 Series

Reviewed by Automotive on

Now into its second generation as a rear-drive car, Infiniti's G series of sport sedans and coupes has seen its fair share of changes since it debuted in 2003. A few features, however, have stayed the same: It's fun to drive and it looks great. These days the top-line Infiniti G37 is powered by a 3.7-liter V-6 engine mated to a seven-speed automatic or six-speed manual transmission.

Infiniti's G37 offers a formidable alternative to BMW's 3 Series with its quick acceleration and sporty handling. Other features include a tuned suspension, four-wheel disc brakes, and summer tires that provide low rolling resistance when in contact with the road. Infiniti also has its German competitor beat when comparing price tags.

Two special models of the coupe are available: The convertible and the IPL. The G convertible has a retractable hard top but is slow to the punch but can be overlooked as the roof opens up to the sky overhead. With a powerful engine, sporty handling, and the option to remove the roof the G37 will give entry-luxury level cars a run for its money. "IPL" stands for "Infiniti Performance Line," and adds horsepower, suspension and appearance to coupes.

What's New

New additions to the G37 for 2012 include refinements to the Limited Edition and Sport Appearance Edition models. A new interior color (graphite) replaces the blood red interior of models past. Other refinements to the Limited Edition include a new black exterior color and 18-inch dark finish aluminum-alloy wheels. Changes to the Sport Appearance Edition include a new black grille. Another version of a black exterior paint is also available on all models except the G25, Limited Edition, and Sport Appearance Edition.


For 2012 the G37 keeps the long, wave-like hood and athletic stance that Infiniti's coupes and sedans are known. The front grille and headlights remain the same after the refresh for the 2010 model year. Fog lights can also be found upfront and high intensity discharge headlights carve a path up ahead in the dark. The sweeping roofline is also present on the coupe and sedans along with sharp, expansive bodylines. LED taillights alert drivers behind that you are coming to a stop and a chrome spoiler sits atop the trunk lid. Dual exhaust tips peek out from underneath the rear bumper giving the G37 a sporty appearance along with 17- or 18-inch aluminum-alloy wheels depending on the trim selected.


Standard interior features include leather-appointed seating, aluminum trim, and an automatic temperature control system. Other features include a six-speaker sound system, satellite radio with real-time traffic and weather updates. Bluetooth enables music to be streamed and Zagat provides a restaurant guide when out perusing for food. There is also a 7.0-inch color monitor touch screen with voice recognition and RearView Monitor. Bluetooth hands-free phone system and Brake Assist with Preview Braking are also available.

Performance & Handling

Under the hood is where the G37 separates itself from the G25 model as it's blessed with a 3.7-liter V-6 engine good for 325-348 horsepower depending on the model. The beefier engine in comparison to its smaller sibling is also mated to a seven-speed automatic transmission but has the option of swapping in a six-speed manual. The engine's Variable Valve Event and Lift system is responsible for boosting fuel economy and lowering the G37's emissions. A "drive-by-wire" throttle system along with Iridium spark plugs dictate the engine's actions and a dual exhaust system relays the engine note. Both the intake manifold and exhaust play a crucial role in delivering that signature Infiniti exhaust note. The G sedan sits on a platform where the engine is placed just behind the front axle to provide solid front-to-rear balance. Handling is improved by the length of the wheelbase, front and rear stabilizer bars, and a combination of aluminum components.


For 2012, the G37 has safety features including Infiniti's Advanced Air Bag System which includes dual-stage front air bags with seat belt sensors. Front seat-mounted side-impact air bags and roof-mounted curtain side impact airbags also guard passengers in the event of an accident. Other standard safety features include 3-point seat belts and front seat belts with pretensioners, active head restraints, and a LATCH system. All G sedans include Zone Body Construction with front and rear crumple zones to deflect and absorb crash energy.
