Overview

What's New for 2013:

  • G25 Sedan cancelled
  • Revised trim selections for G coupe
  • IPL G Convertible debuts

Exterior Features
The Infiniti G lineup includes a sedan, coupe, and a convertible. Trim levels vary by body style, and all-wheel drive (AWD) is available for the G Sedan and G coupe, denoted by an "x" on the trunk lid. Infiniti Performance Line (IPL) versions of the G coupe and G Convertible carry "IPL" badges and special design modifications to set them apart from other models. Convertibles have a power-retractable hardtop that stows in the trunk. All variants are equipped with aluminum wheels and xenon HID headlights.

Interior Features
The Infiniti G is equipped with leather, power front seats, dual-zone automatic climate control, Infiniti Intelligent Key with push-button ignition, Bluetooth, and more.

Optional Features
Highlights from the options list include a Bose Studio on Wheels premium audio system, hard-drive navigation system with voice-recognition technology, power sunroof, and a Technology package loaded with safety features. A Sport package adds more aggressive tires, sport suspension, sport-tuned steering, sport brakes, magnesium paddle shifters (with automatic transmission), power front sport seats, revised styling, and unique 18-inch aluminum wheels.

Under the Hood
With the cancellation of the G25 Sedan, every 2013 Infiniti G is equipped with a 3.7-liter V-6 engine paired with a choice between a 6-speed manual gearbox and a 7-speed automatic transmission with adaptive shift control, Drive Sport mode, and Downshift Rev Matching. In G37 models, the V-6 makes 325-330 horsepower, depending on body style. In IPL trim, the V-6 generates 343-348 horsepower. Infiniti's Intelligent All-Wheel Drive is available on the G37x coupe and G37x Sedan.

Fuel Economy
As this overview was written, the EPA had not finalized fuel-economy estimates for all Infiniti G models. Below, we provide a mix of official 2012 and 2013 data:
  • G37 Sedan with manual transmission: 17/25/19 mpg (city/highway/combined)
  • G37 coupe with manual transmission: 17/25/20 mpg
  • G37 coupe and Sedan with automatic transmission: 19/27/22 mpg
  • G37x AWD coupe and Sedan with automatic transmission: 18/25/20 mpg
  • G37 Convertible with manual transmission: 16/24/19 mpg
  • G37 Convertible with automatic transmission: 17/25/20 mpg

Safety
Every Infiniti G is equipped with 6 standard air bags, including the G Convertible, which also features pop-up roll bars to help protect occupants in a rollover accident. Traction and stability control are also standard, along with 4-wheel-disc anti-lock brakes with brake assist and a reversing camera. Rear parking-assist sensors are optional on all G37 models. A Technology package is also available, adding rain-sensing wipers, Pre-Crash Seat Belts, intelligent cruise control, and Preview Braking.

The National Highway Traffic Safety Administration (NHTSA) has not performed crash tests on the Infiniti G lineup. However, the Insurance Institute for Highway Safety (IIHS) says the G provides "Good" protection in frontal- and side-impact crashes, but rear-impact injury prevention is "Marginal." Roof crush strength is rated as "Acceptable" by the Institute.
