The INFINITI G lineup starts with the G25 family, the more approachable 2.5-liter V6 sedans. The core G37 branch brings the stronger 3.7-liter V6 and spans everyday Journey models, all-wheel-drive G37x versions, sport-look editions, and a hardtop convertible. The G37 Sport is the hands-on choice with a manual transmission and sharper driving hardware. Anniversary and Limited Editions are loaded sedan specials, while the IPL is the factory-tuned performance model with extra power, distinct styling, and a more focused chassis.
The Base Model trim level—G25, G25 Journey, and G25x—is the entry point to the G sedan, pairing a smaller V6 with a luxury cabin and either simple rear-wheel drive or all-weather traction.
Best for: Drivers who want the G sedan’s style and comfort without the stronger performance focus of a G37.
Highlights
The Mid-Level trim level—G37, G37 Journey, the Sport Appearance Editions, G37x, and G37x Sport Appearance Edition—is the heart of the range, built around strong V6 power, everyday luxury, and several body-style and traction choices.
Best for: Shoppers seeking the classic G balance of performance, comfort, and daily usability.
Highlights
Moves beyond the G25 group with the stronger 3.7-liter V6, heated front seats, a rearview camera, and xenon headlights. The family also expands beyond sedans to coupe and hardtop-convertible versions, while G37x models provide all-wheel drive.

The Sport Styling trim level—G37 Sport—is the driver-focused G, defined by its 6-speed manual transmission and hardware that makes steering, braking, and seating feel more purposeful.
Best for: Drivers who want a more hands-on experience and value control and feedback over all-weather traction.
Highlights
Adds a 6-speed manual, larger brakes, sharper steering, more supportive front seats, and sport-styled bodywork over the core G37 models.

The Special Editions trim level—G37 Anniversary Edition, G37 Limited Edition, and G37x Limited Edition—groups the loaded sedan specials that bundle premium cabin technology with distinctive styling and, on Limited models, added sport hardware.
Best for: Sedan shoppers who want luxury, technology, and a more exclusive factory package in one model.
Highlights
Shifts from the G37 Sport’s manual-first character to a loaded automatic sedan package with Bose audio and hard-drive navigation. Limited models add sport brakes and sharper chassis hardware, while the G37x Limited Edition adds all-wheel drive.

The High Performance trim level—IPL—is the limited-production, factory-tuned G coupe and convertible, combining added V6 output with sharper chassis tuning and unique styling without stripping away cabin comfort.
Best for: Enthusiasts who want the most focused factory performance version while keeping premium seating, audio, and navigation.
Highlights
Adds an IPL-tuned engine, suspension and steering, unique exterior pieces, larger sport brakes, and IPL-specific cabin details. Unlike the sedan-only special editions, IPL models are coupes or convertibles.

They identify two engine families. The G25 was a 2011–2012 sedan with a 2.5-liter V6. The G37 used the stronger 3.7-liter V6 and appeared as a sedan, coupe, or convertible, depending on model year and trim.
In the 2011–2012 lineup, the base G25 was the simplest rear-wheel-drive sedan with the smaller 2.5-liter V6 and seven-speed automatic. It retained leather-appointed seats, automatic climate control, power front seats, and a 7-inch display.
For 2011–2012 models, the G25 Journey adds the everyday conveniences missing from the base G25: heated front seats, two-zone climate control, a reversing camera, Bluetooth phone connectivity, and a USB audio connection.
The G25x is essentially the all-weather member of the 2011–2012 G25 family. It combines the smaller V6 and Journey-level comfort equipment with all-wheel drive. The G25 Journey keeps rear-wheel drive.
Pick the 2011–2012 G25 if the G sedan’s cabin and rear-drive character matter more than stronger acceleration. Pick a G37 Journey for the more powerful 3.7-liter V6 and the choice of sedan or coupe body styles in this era.
The main difference is traction. In the 2009–2013 lineup, G37 Journey is the rear-wheel-drive, comfort-focused version, while G37x adds all-wheel drive. Both use the 3.7-liter V6, a seven-speed automatic, heated leather-appointed seats, and a reversing camera.
G37 Journey emphasizes everyday comfort with a seven-speed automatic. In this generation, G37 Sport is the hands-on driver’s version, pairing a six-speed manual with larger brakes, sharper steering, more supportive seats, and sportier bodywork.
No. In the special-edition years, the Sport Appearance Edition uses an automatic transmission and focuses on styling, a moonroof, and Bose audio. G37 Sport is the functional performance trim with a manual transmission, larger brakes, sport steering, and supportive seats.
In the late-cycle lineup, a plain G37 trim name generally identifies the automatic hardtop convertible. It combines the 3.7-liter V6 with a power-folding metal roof, heated leather-appointed seats, a reversing camera, and climate control tuned for roof-up or roof-down driving.
In the 2011–2012 special-edition lineup, the G37 Limited Edition is rear-wheel drive and adds a limited-slip rear differential with its sport suspension. The G37x Limited Edition uses all-wheel drive instead, while retaining the loaded cabin and sport-focused equipment.
The Anniversary Edition was a 20th-anniversary model focused on exclusivity and bundled luxury technology. The later Limited Edition sedan went further with sport brakes, a sport-tuned suspension, sport seats, paddle shifters, and, on the rear-drive version, a limited-slip differential.
IPL is the limited-production, factory-tuned performance G sold in coupe and later convertible form. It adds a stronger version of the 3.7-liter V6, sharper suspension and steering, larger brakes, unique bodywork, red-stitched sport seats, Bose audio, and built-in navigation.
In the 2011–2013 era, IPL goes beyond the regular G37 Sport with extra engine output, IPL-specific suspension and steering tuning, unique exterior pieces, red-stitched branded seats, Bose audio, and built-in navigation. Both retain larger sport brakes and a driver-focused character.
An x-badged trim is the clearest fit because it has all-wheel drive. G25x covers the smaller-engine 2011–2012 sedan, while G37x keeps the stronger V6 and appears in sedan or coupe form during this generation. Tires and vehicle condition still matter greatly.
Look for G37 Sport in the 2009–2013 lineup. It pairs a six-speed manual with larger brakes, sport-tuned steering, and more supportive front seats. IPL coupes were also sold in a manual form during their shorter 2011–2013 run.
No. Equipment varies by trim and model year. During the special-edition years, the Limited Editions bundled navigation and Bose audio, and IPL included both. Regular G trims may have simpler audio and display setups, so verify the equipment on the individual car.
