The INFINITI FX lineup starts with the FX35 and later FX37, the core V6 models that deliver the FX’s sporty, luxury-focused character. The FX35 Limited Edition and FX37 Limited Edition add a darker look, 21-inch wheels, navigation, and a surround-view parking camera. The FX50 sits at the top with a 390-hp V8, standard all-wheel drive, richer front seats, and greater towing capacity.
The Core Model trim level — FX35 and FX37 — is the main FX formula: a V6-powered luxury crossover that puts bold styling and responsive driving ahead of maximum utility.
Best for: Drivers who want the FX’s distinctive shape, upscale cabin, and performance-focused feel without the Limited Edition extras or the FX50’s V8.
Highlights
The Special Editions trim level — FX35 Limited Edition and FX37 Limited Edition — is the dressed-up V6 branch, bundling dark exterior details with prominent convenience technology.
Best for: Shoppers who want the V6 FX with a more distinctive appearance and a fuller set of parking, navigation, and driver-memory features.
Highlights
Adds standard all-wheel drive, 21-inch graphite-finish wheels, adaptive headlights, navigation, a surround-view parking camera, and driver memory over the regular V6 models.

The names identify the engine. The FX35 uses a 3.5-liter V6, the later FX37 uses a 3.7-liter V6, and the FX50 uses a 5.0-liter V8. They are versions of the same basic SUV, not different body sizes.
The main difference is the V6. Earlier second-generation FX35 models have a 303-hp 3.5-liter engine, while the FX37 name arrived when a 325-hp 3.7-liter V6 replaced it for 2013. Both serve as the core V6 FX.
The FX37 has a 325-hp V6, while the FX50 has a 390-hp V8 and standard all-wheel drive. In the later lineup, the FX50 also brings 21-inch wheels, navigation, a surround-view camera, and richer heated and ventilated front seats.
In the later lineup, the FX37 Limited Edition adds standard all-wheel drive, 21-inch dark-finish wheels, adaptive headlights, navigation, a surround-view camera, parking sensors, and driver memory. It keeps the regular FX37’s 325-hp V6.
For 2012, the FX35 Limited Edition builds on the all-wheel-drive V6 model with 21-inch dark-finish wheels, adaptive headlights, navigation, a 360-degree parking camera, parking sensors, and memory for the driver’s seat, mirrors, and steering wheel.
They are the same basic special-edition idea from different points in the lineup. The FX35 Limited Edition uses the 303-hp 3.5-liter V6, while the later FX37 Limited Edition uses the 325-hp 3.7-liter V6. Both bundle dark styling and premium technology.
No. Within the same era, the Limited Edition keeps the regular model’s V6. Its upgrades center on all-wheel drive, darker exterior details, larger wheels, navigation, parking cameras, and driver-memory features rather than extra engine output.
The core FX35 or FX37 is the straightforward everyday choice. It keeps the FX’s styling, V6 performance, heated leather front seats, rearview camera, and power liftgate without requiring the Limited Edition’s appearance extras or the FX50’s V8.
The FX50 is the performance choice. Its 390-hp 5.0-liter V8 is substantially stronger than the 303-hp FX35 V6 or 325-hp FX37 V6, and all-wheel drive is standard.
A Limited Edition is the V6 choice for bundled technology. In 2012–2013, these models combine navigation, a surround-view parking camera, parking sensors, adaptive headlights, and driver memory with the era’s V6 and all-wheel drive.
The FX50 is the V8 model. Across the 2009–2013 second generation, it uses a 390-hp 5.0-liter V8 with all-wheel drive and sits above the V6-powered FX35 and FX37.
In the later lineup, the FX35 Limited Edition, FX37 Limited Edition, and FX50 carry the surround-view parking camera. Moving-object detection was added to the FX50 and FX37 Limited Edition for 2013.
The FX50 is the trim with ventilated front seats in the later lineup. Its quilted leather front seats are both heated and ventilated, while the core V6 and Limited Edition models have heated leather front seats.
In the 2012–2013 lineup, the Limited Edition models and FX50 use 21-inch wheels. The Limited Editions stand out with a graphite-style finish and darker exterior details, while the FX50 pairs its large wheels with the V8.
