Nissan Fuga and Infiniti: how are these models related and how do they differ?

If you've ever wondered what model Infiniti corresponds Nissan Fuga, then don’t be surprised - this is one of the most confusing stories in the world of the Japanese automobile industry. The point is that Fuga (known outside Japan as Nissan Teana) and some models Infiniti built on the same platform, but positioned completely differently. In this article we will figure out which versions Infiniti are "twins" Fuga, how they differ under the hood and why the Japanese decided to divide them into two brands.

Spoiler: the answer is not as simple as it seems. Nissan Fuga first generation (2004–2009) - this is actually Infiniti M35/M45 for the domestic market, and the second generation (2009–2014) is already closer to Infiniti M25/M37/M56. But there are nuances that are not written about even in official brochures. Next is a detailed analysis with technical data, comparison tables and answers to frequently asked questions from owners.

Why Nissan Fuga And Infiniti - is it almost the same thing?

It's all about strategy Nissan on market segmentation. Brand Infiniti was created specifically for North America and Europe as a premium offshoot, while Fuga (and later Teana) were sold in Asia under the brand Nissan. At the same time, the cars were assembled on the same conveyors and used common platforms FM (Front Midship) and even shared engines among themselves. For example, 3.5 liter VQ35HR was also installed on Fuga 350GT, and on Infiniti M37.

The key differences are in the suspension settings, trim level and, of course, the price tag. Infiniti positioned as a competitor BMW 5 Series And Mercedes E-Class, whereas Fuga in Japan it was a "premium sedan for middle managers." Interestingly, in some countries (for example, Russia) Teana sold in parallel with Infiniti M, but at a price 30–40% cheaper.

• 🔧 Common platform: FM (also used in Nissan Skyline And Infiniti G/Q50).
• 💺 Salon: Fuga had a simpler finish (plastic instead of wood/aluminum in Infiniti).
• 🚗 Engines: VQ35DE, VQ35HR, VQ45DE - the same for both brands.
• 📏 Dimensions: the bodies are identical, but Infiniti often equipped with more aggressive bumpers.

First generation Fuga (2004–2009) = Infiniti M35/M45 (2005–2010)

Debut Nissan Fuga (body code J31) appeared in 2004 exclusively for the Japanese market. A year later her twin - Infiniti M35/M45 — released in the USA and Europe. The differences between them were minimal:

• 🔑 Engines:
  • Fuga 250GT — VQ25HR (2.5 l, 220 hp)
  • Fuga 350GT — VQ35DE (3.5 l, 280–303 hp)
  • Infiniti M35 - the same VQ35DE, but with different firmware (303 hp versus 280 for Fuga).
  • Infiniti M45 — VQ45DE (4.5 l, 335 hp), which was not in the lineup Fuga.
• 🎛️ Transmission: both models were equipped with a 5-speed automatic transmission RE5R05A, but in Infiniti it had a sport mode DS (Downshift Rev Matching).
• 🛣️ Suspension: Infiniti M received adaptive shock absorbers CDC (Continuously Damping Control), which were not included in the base Fuga.

Important fact: Fuga 350GT Four (all-wheel drive version) used the system ATTESA E-TS, similar Infiniti M35x, but with different torque distribution settings (37:63 versus 50:50 for the American version).

Parameter	Nissan Fuga (J31)	Infiniti M35/M45 (Y50)
Years of production	2004–2009	2005–2010
Length/width/height (mm)	4930×1820×1490	4930×1820×1490
Wheelbase (mm)	2850	2850
Max. power (hp)	280 (350GT)	303 (M35) / 335 (M45)
Drive	Rear/Full (Four)	Rear/Full (x)

⚠️ Attention: When purchasing spare parts for Fuga J31 pay attention to the article numbers - some parts (for example, front struts) are interchangeable with Infiniti M Y50, but shock absorbers and springs have different stiffnesses. Installation of "infinite" spare parts on Fuga will lead to deterioration in comfort.

Second generation Fuga (2009–2014) = Infiniti M25/M37/M56 (2010–2013)

With the release of the second generation (J32 for Fuga And Y51 for Infiniti M) the differences between the models became more noticeable. Nissan focused on comfort and reliability, and Infiniti - on a sporty character. For example:

• 🔥 Engines:
  • Fuga 250GT — VQ25HR (231 hp)
  • Fuga 370GT — VQ37VHR (333 hp)
  • Infiniti M37 - the same VQ37VHR, but with a different exhaust system (330 hp due to environmental regulations).
  • Infiniti M56 — VK56VD (5.6 l, 420 hp), which was not in the lineup Fuga.
• 🎚️ Suspension: Infiniti M got the system 4WAS (4-Wheel Active Steer), which was absent even in the top Fuga 370GT Type P.
• 🖥️ Electronics: B Infiniti package was available Technology Package with adaptive cruise control and collision avoidance system, while Fuga offered only basic Intelligent Cruise Control.

Interesting point: Fuga Hybrid (2010–2014) with hybrid installation VQ35HR + electric motor (360 hp) had no analogue in the line Infiniti. This version was exclusive to the Japanese market and was positioned as an "eco-friendly premium sedan".

Why Infiniti M56 didn't sell it like Fuga in Japan?

In Japan, there is a tax on cars with engines over 3 liters, which made M56 (5.6 l) economically unprofitable for the local market. In addition, Nissan tried to preserve the image Fuga as a “rational premium”, whereas Infiniti M56 positioned as a sports sedan with an aggressive character.

What else is different? Fuga And Infiniti besides the name?

In addition to the obvious differences in interior trim and chassis settings, there are a number of nuances that only experienced owners know about:

   • Fuga Four uses ATTESA E-TS Pro with a clutch in the transfer case.
   • Infiniti Mx equipped with a system ATTESA E-TS with electronic control, but without mechanical locking.

Brake system: Infiniti M37/M56 had larger brake discs (355 mm in front versus 320 mm in Fuga) and 4-piston calipers Brembo in top versions.

Steering: B Infiniti a steering mechanism with a variable gear ratio was used (DSS - Direct Adaptive Steering), whereas Fuga received a standard hydraulic booster.

Another little known fact: body Fuga And Infiniti M second generation have different thicknesses of anti-corrosion coating. Japanese versions (Fuga) were processed according to the standard Zincrometal with a 7-year guarantee against through corrosion, while American Infiniti received simpler coverage (5 year warranty).

Look at the radiator grille (at Infiniti - double arc, y Fuga — horizontal bars)|Check for the presence of the inscription "Infiniti" on the rear (at Fuga - emblem only Nissan)|Pay attention to the exhaust pipes (at Infiniti M56 - square pipes, Fuga 370GT — round)|Look at the rims (the “5-spoke” design is typical for Infiniti, "10-spoke" - for Fuga Type P)

• 💰 Price: Fuga/Teana on the secondary market it is 20–30% cheaper for the same mileage. For example, Fuga 370GT 2012 in Russia costs ~1.2 million rubles, while Infiniti M37 the same year - from 1.8 million rubles.
• 🛠️ Service: Spare parts for Fuga (especially Japanese assembly) are cheaper and more accessible. For example, the original radiator on Infiniti M costs 40% more.
• 🚀 Dynamics: Infiniti M56 with engine VK56VD accelerates to 100 km/h in 5.1 s, while the top Fuga 370GT spends 6.2 s on this.
• 🛋️ Comfort: Fuga softer and quieter on the move thanks to different shock absorber settings and sound insulation.

If you need reliable sedan for a family with low cost of ownership - take it Fuga 250GT or Teana. If you want sporty character and premium status - look to the side Infiniti M37/M56.
