About the 2013 INFINITI G

V36 generation, late-cycle year before the all-new Q50 sedan arrived and before the coupe/convertible shifted to Q60 badging.

INFINITI positions the G as a luxury sport family first and foremost: strong naturally aspirated V6 power, rear-drive feel, sharp handling, and an upscale cabin with real comfort features. What separates it from many rivals is the broad spread of personalities under one model line — sedan, coupe, hardtop convertible, AWD variants, manual-transmission sport versions, and the more exclusive IPL models. For most shoppers, the G’s appeal is simple: it mixes everyday usability with a faster, more expressive character than a typical entry-luxury car.

The 2013 G covers several personalities: the Journey emphasizes everyday comfort, the G37x adds all-wheel drive, and the Sport 6MT uses a six-speed manual transmission with sharper steering and larger brakes. The regular convertible has a three-piece power-folding metal roof, while the IPL models pair a tuned V6 with sport suspension, stronger brakes, unique bodywork, and navigation. Heated leather seats and a rearview camera are common signature features across the range.

Frequently asked questions

What is the biggest change to the 2013 INFINITI G?

The biggest change is the addition of the IPL G Convertible. It brings INFINITI's factory-tuned performance treatment to the retractable-hardtop G, including a tuned 3.7-liter V6, sport suspension and steering, larger brakes, and unique body styling.

Did INFINITI still offer the G25 for 2013?

No. The G25, G25 Journey, and G25x leave the lineup for 2013, so the U.S. G family is centered on models powered by the 3.7-liter V6.

Which 2013 INFINITI G sedan versions remained after the lineup was simplified?

The simplified 2013 sedan lineup consists of the rear-wheel-drive G37 Journey, the all-wheel-drive G37x, and the manual-transmission G37 Sport 6MT. The prior G25 versions and several special-edition G37 variants are gone.

What changed on the 2013 INFINITI G Coupe?

The G37 Journey becomes the entry coupe after the previous base G37 Coupe is dropped. Journey and G37x coupes receive revised cabin trim, while the Sport 6MT Coupe gains navigation content as standard equipment.

Was the 2013 INFINITI G a full redesign?

No. The 2013 G remains part of the V36 generation and receives a light late-cycle update rather than a full redesign. Most regular sedan, coupe, and convertible hardware carries over.
