  • Power-retractable hardtop
  • Base, Sport 6MT, and IPL trim levels
  • Choice of manual or automatic transmission


Infiniti's svelte 2-door G37 Convertible carries on into 2013 looking much like its predecessor, though the lineup now includes a new IPL (Infiniti Performance Line) trim level offering a more aggressive appearance paired with more power under the hood.

Infiniti is renaming all of its models for the 2014 model year, at which time the G37 Convertible will become the Q60 Convertible.

Exterior Features

In an effort to stand out in a class that includes competitors like the Audi A4 Cabriolet and the BMW 3 Series Convertible, Infiniti has bestowed its base G37 Convertible with sculpted bodywork, a 3-piece power-retractable hardtop roof, automatic HID headlights, heated power-folding outside mirrors, LED brake lights, fog lights, and 18-inch alloy wheels wrapped in performance tires.

Those items are shared with the Sport 6MT (6-speed manual transmission) model, which also boasts a revised front bumper, 19-inch alloy wheels, and rear park-assist sensors. The IPL G37 Convertible dials things up another notch with unique 19-inch alloy wheels, lower body kit, rear spoiler, and outside mirrors with 2-setting memory.

Interior Features

Like its exterior, the 2013 Infiniti G37 Convertible's interior earns its luxury-car stripes with a host of amenities. For the base model, those include push-button start, leather upholstery, heated power front seats with 8-way adjustment for the driver and passenger, leather-wrapped tilt-and-telescoping steering wheel with integrated audio controls, aluminum trim, and electroluminescent gauges. The assortment of standard features continues with Bluetooth connectivity, a 6-speaker sound system, USB port, satellite radio service, central control dial linked to a 7-inch display, and an auto-dimming rearview mirror.

From there, the Sport 6MT variant moves further upscale with the addition of aluminum foot pedals, heated and cooled power front seats with 12-way adjustment for the driver and 8-way adjustment for the passenger, extra memory functions, power tilt-and-telescoping steering wheel, 13-speaker premium audio, and a touch-screen navigation system offering voice activation, real-time weather and traffic information, and 3-D map graphics.

The IPL G37 Convertible shares its list of standard interior equipment with the Sport 6MT, excluding minor differences such as IPL-embroidered seats.

Optional Features

Buyers of the base 2013 G37 Convertible have several available options to consider, including a Navigation package, Performance Tire and Wheel package, Interior Accents package with maple wood trim, and a Premium package comprised of the 13-speaker premium sound system, heated and cooled front seats, power tilt-and-telescoping steering wheel, and rear park-assist sensors.

Infiniti also offers a Sport package that's equipped with 19-inch alloy wheels, aluminum foot pedals, paddle shifters, revised front bumper, and performance-tuned steering and brakes.

Rounding out the selection of upgrades is a Technology package that consists of intelligent cruise control, automatic climate control with air purification, and rain-sensing wipers.

Under the Hood

Infiniti equips the 2013 G37 Convertible with a 3.7-liter V-6 engine that delivers 325 horsepower and 267 lb.-ft. of torque. Available transmissions include a 6-speed manual or 7-speed automatic with manual and sport modes, as well as downshift rev matching.

The 2013 IPL G37 Convertible utilizes the same engine, though a dual exhaust system helps produce 343 horsepower and 273 lb.-ft. of torque. The 7-speed automatic transmission is standard, as are steering-wheel-mounted paddle shifters and a performance-tuned chassis.

Fuel Economy

EPA fuel-economy estimates for the 2013 Infiniti G37 Convertible are:

  • G37 Convertible with manual transmission: 16/24/19 mpg (city/highway/combined)
  • G37 Convertible with automatic transmission: 17/25/20 mpg


The 2013 Infiniti G37's standard safety features include 6 air bags, traction control, rearview camera, front active head restraints, rear roll bars, 4-wheel anti-lock ventilated disc brakes, electronic brake-force distribution, and brake assist.

In crash tests conducted by the Insurance Institute for Highway Safety (IIHS), the 2013 Infiniti G37 Convertible received a "Good" rating--the Institute's highest--for moderate frontal-offset crash protection. As this preview is written, the National Highway Traffic Safety Administration (NHTSA) has not rated the crashworthiness of the 2013 Infiniti G37 Convertible.


Pre-collision braking--what Infiniti calls Preview Braking--is part of the available Technology package. The system works by using sensors to determine the likelihood of the G Convertible striking the vehicle ahead and, if necessary, readies the brakes for a sudden stop.
