Best Infiniti FX35 Model Years (Ranked)
The Infiniti FX35 helped invent the performance-crossover niche, pairing the muscular 3.5L VQ35 V6 with sharp, sports-sedan handling and a low-slung "bionic cheetah" shape that still looks aggressive today. Sold across two generations, the first-generation S50 (2003-2008) and the second-generation S51 (2009-2013), the FX35 traded outright cargo space for genuine driver appeal, available in rear-wheel drive or all-wheel drive.
On the used market it is a compelling value, but model year matters: early electronics, brake and tire wear, and a known timing-chain-tensioner concern on the VQ engine all reward careful shopping. This ranking covers the best FX35 model years, their engines, and where the smart money goes today.
Direct Answer
The best overall Infiniti FX35 is the 2011-2013 second-generation (S51) model, which offers the most refined version of the VQ35 V6, improved interior materials, updated electronics, and the strongest safety equipment while keeping the FX's signature handling. For shoppers focused on value, the best value is the 2006-2008 first-generation (S50) FX35, which received key updates over the launch cars, has proven durable, and now sells for a fraction of its original price.
Note that the FX37 (3.7L V6) and FX45/FX50 (V8) are distinct, more powerful variants; this ranking focuses on the 3.5L FX35 while placing those siblings in context. Buy any FX35 with documented timing-chain and brake service.
1. 2011-2013 Second Generation (S51) 🏆 BEST OVERALL
The final FX35 model years are the best the nameplate offered. The second-generation S51 rides on a stiffer platform with a more upscale cabin, better materials, and a smoother, 303-hp 3.5L VQ35 V6 mated to a seven-speed automatic. Handling remained a high point, with quick steering and strong body control that few crossovers matched.
By 2011 Infiniti had refined the electronics and added more standard equipment, and available all-wheel drive broadened year-round usability. These are the most modern, most reliable FX35s on the used market, and prices remain reasonable for the performance and image on offer.
2. 2006-2008 First Generation (S50, Updated) 💎 BEST VALUE
The later first-generation FX35 is the value champion. Across 2006-2008 Infiniti refined the original formula with interior and equipment updates while keeping the proven 3.5L VQ35 V6 (around 275-280 hp) and a five-speed automatic. The chassis still delivers the sharp, sporty driving feel that defined the FX, and rear- or all-wheel drive suits varied climates.
The best value is a 2006-2008 FX35 AWD with full service history, which now sells for a small fraction of its original price while offering V6 smoothness and bold styling. These cars are durable when timing-chain and brake maintenance is documented.
3. 2009-2010 Second Generation (S51, Early)
The early second-generation FX35 introduced the redesigned S51 platform, with a more powerful 303-hp VQ35 V6, a seven-speed automatic, and a noticeably more premium interior than the outgoing car. Styling grew even more dramatic, and handling stayed sharp. These early S51 years offer most of the benefits of the best-overall 2011-2013 cars at a lower price, with the main trade-off being slightly older infotainment and fewer refinements.
A clean 2009-2010 FX35 is a strong pick for a buyer who wants the second-generation driving experience and look while saving money over the latest model years.
4. 2009-2013 Infiniti FX37 (S51) — 3.7L Variant
For 2013, Infiniti replaced the FX35 badge in some markets with the FX37, powered by the larger 3.7L VQ37VHR V6 producing roughly 325 hp. Mechanically similar to the second-generation FX35, the FX37 adds noticeably more power and a higher rev ceiling while retaining the same chassis, seven-speed automatic, and available AWD.
It is the natural step up for a buyer who wants the second-generation FX experience with extra punch. Treat the FX37 as the FX35's more powerful sibling, the same handling and refinement with a stronger engine, and shop it with the same maintenance scrutiny.
5. 2003-2005 First Generation (S50, Launch)
The original FX35 launched the performance-crossover concept and remains historically significant. The 3.5L VQ35 V6 (around 280 hp) and a five-speed automatic delivered genuinely quick, engaging performance, and the radical styling turned heads. These launch cars are now the most affordable FX35s, but they are also the oldest, so expect aging electronics, worn suspension bushings, and the need for thorough timing-chain and brake inspection.
A well-kept 2003-2005 example is a fun, cheap entry into FX ownership, best suited to enthusiasts who accept higher maintenance on an older performance vehicle.
6. 2009-2013 Infiniti FX50 (S51) — 5.0L V8
The FX50 is the second-generation flagship, powered by a 5.0L VK50VE V8 producing roughly 390 hp. It adds available adaptive suspension and other performance hardware, making it the fastest FX of the era. While not an FX35, it is essential context: the FX50 is for buyers who prioritize outright speed and are comfortable with higher fuel and maintenance costs.
It is the muscle version of the FX35's chassis, thrilling but thirstier and more expensive to run. For most shoppers the V6 FX35 or FX37 is the more sensible everyday choice.
7. 2003-2008 Infiniti FX45 (S50) — 4.5L V8
The first-generation FX45 paired the same bold body with a 4.5L VK45DE V8 making around 315-320 hp, serving as the performance flagship of the S50 generation. It is quicker than the FX35 and sounds the part, but it drinks more fuel and costs more to maintain. As context for FX35 shoppers, the FX45 shows the range of the lineup: the FX35 is the value-and-efficiency choice, the FX45 the power choice.
A clean FX45 appeals to enthusiasts, but the V6 FX35 remains the smarter pick for daily use and running costs.
8. 2008 First Generation (S50, Final Year) — RWD
The final 2008 model year of the first-generation FX35 is worth singling out for buyers who want the last and most-refined S50 in rear-wheel-drive form. RWD examples deliver the purest expression of the FX's sporty balance and can be slightly more efficient than AWD versions in dry climates.
By 2008 the first generation had accumulated its running updates, making these among the better early cars. A 2008 RWD FX35 is a good choice for warm-weather buyers who prioritize handling feel, though AWD remains the safer pick for snow-belt drivers.
9. 2006-2008 First Generation (S50) — AWD (High Mileage, Caution)
Higher-mileage all-wheel-drive first-generation FX35s can be tempting bargains, but they demand caution. The AWD system adds components that wear and cost more to service, and on neglected cars the timing chain tensioner, brakes and rotors, and suspension bushings may all need attention at once.
The VQ35 is durable, but deferred maintenance is the enemy. Only buy a high-mileage AWD FX35 with documented service, especially proof of timing-chain and brake work. Otherwise the repair bills can quickly exceed the low purchase price, undermining the value that makes the FX35 attractive.
10. 2003-2005 First Generation (S50, High Mileage, Caution)
The earliest, highest-mileage FX35s sit at the bottom of the ranking. These launch-era cars combine the oldest electronics with the most accumulated wear, and common issues like a noisy timing-chain tensioner, rapid brake and tire wear, dashboard and trim aging, and tired suspension are most likely here.
They are the cheapest FX35s for a reason. Treat a high-mileage 2003-2005 car as a project or budget enthusiast buy, not a worry-free daily driver. A pre-purchase inspection is essential, and you should budget for catch-up maintenance on top of the low asking price.
What to Watch For When Buying
The most important checks on a used FX35 center on the 3.5L VQ35 V6. Listen for a rattle at startup that signals a worn timing chain tensioner, a known VQ concern, and confirm it has been serviced if present. The FX is heavy and sporty, so brakes, rotors, and tires wear quickly; budget for them and inspect their condition closely.
On all-wheel-drive cars, verify the system engages smoothly and check for transfer-case or driveline noise. Inspect the suspension bushings and struts on higher-mileage examples, as the firm sport tuning is hard on components. Older first-generation cars can show aging electronics and trim, including infotainment and dashboard issues, so test every feature.
Above all, favor a car with documented maintenance over the cheapest sticker, since deferred service erases the FX35's value advantage.
How to Choose
Match the FX35 to your priorities. For the best blend of refinement, reliability, and modern features, the 2011-2013 second-generation S51 is the answer, with the smoothest VQ35 and the strongest equipment. For the best value, a 2006-2008 first-generation FX35 delivers the sporty driving feel and bold styling at a low used price.
Buyers who want more power should look at the FX37 (3.7L) or the V8-powered FX45 and FX50, accepting higher running costs. Snow-belt drivers should prioritize all-wheel drive, while warm-climate enthusiasts may prefer the lighter, sportier rear-wheel-drive cars. In every case, confirm timing-chain and brake service and prioritize a clean maintenance history.
