Nissan has finally confirmed in writing what many of us had known all along... the 2009 model year will bring the new G37 Sedan, G37 Convertible, and the G37x Coupe to Infiniti showrooms. The G35 sedan gets a bump from 3.5-liters (306 hp) to 3.7-liters (328 hp) as it now shares its engine with the coupe. Rebadged the G37, an optional brake package adds 4-piston front/2-piston rear brakes and larger rotors to the sedan. A new 18-inch wheel design and standard Scratch Shield paint (self-healing) round out the upgrades. The all-new G37 convertible marks Infiniti's first drop-top since the 1992 M30 was discontinued, and the first open-air G. Based on the G37 Coupe, it features a three-piece automatic retracting hardtop. Finally, the new G37x is a G37 coupe fitted with Nissan's ATESSA E-TSÔ all-wheel drive system. While the G37 Sedan and G37x will go on sale in September and debut in less than two weeks at the 2008 Pebble Beach Concours d'Elegance, we'll have to wait until the LA Auto Show in November for the debut of the G37 Convertible. Of course, Autoblog will be at both events to cover it for you.

When you have a vehicle line – say the Infiniti G – that has chalked up award after award, topped comparison test after comparison test, and endeared itself to a growing legion of passionate owners, what do you do for an encore? If you happen to be a world-class performance luxury brand – say like Infiniti – the answer is simple: Everything. The popular Infiniti G roars into the 2009 model year with an extensive array of changes, including:

  • The addition of an all-new Infiniti G37 Convertible model, slated to launch in the first quarter of 2009
  • A new 328-horsepower 3.7-liter V6 engine for the Infiniti G Sedan – now designated the G37 Sedan
  • A new all-wheel drive model for the Infiniti G Coupe, the G37x
  • A new 7-speed automatic transmission for all Infiniti G models (6-speed manuals transmissions also available)

"A little success makes you want to try harder. A lot of success makes you want to blow the doors off the competition again – which we're poised to do with the new, intensified Infiniti G lineup for 2009," said Ben Poore, Infiniti's vice president of marketing. "Year after year we strive to offer our customers one of the freshest product lineups in the industry – which we've done again in 2009 with the new second-generation Infiniti FX, upcoming G Convertible and the enhanced G37 Coupe and G37 Sedan."

2009 Infiniti G37 Convertible

The all-new G37 Convertible, the first-ever open-air G, is set for a mid-2009 model year introduction. Based on the current G37 Coupe, the G Convertible promises stunningly seductive styling and G-worthy dynamic performance. The new G37 Convertible will feature a three-piece automatic retracting hardtop, to keep a coupe-like roofline, and available unique interior treatment. Audio and HVAC systems have been enhanced to provide an inviting experience with the top up or down. The all-new Infiniti G37 Convertible is set to make its world debut at the 2008 Los Angeles Auto Show in November.

2009 Infiniti G37 Sport Sedan

The Infiniti G premium high-performance sport sedan receives a significant upgrade under the skin in 2009 with the addition of a new VQ37VHR "VVEL" 3.7-liter V6 rated at 328 horsepower. It is mated to a new 7-speed automatic transmission or close-ratio 6-speed manual transmission.

Now designated as the Infiniti G37 Sedan, other major changes include new available sport brakes with 4-piston front/2-piston rear calipers and large 14-inch front and 13.8-inch rear rotors, a new sport 18-inch wheel design and standard Scratch Shield paint (self-healing clearcoat finish).

The 2009 G37 Sedan is available in four models – G37, G37 Journey, G37S Sport 6MT and G37x AWD. It goes on sale in September 2008.

2009 Infiniti G37 Sport Coupe

For 2009, the G37 Coupe's performance envelope expands with the addition of a new G37x AWD model with advanced ATESSA E-TSÔ all-wheel drive system. Also new for 2009 is a 7-speed automatic transmission with Drive Sport (DS) Mode and Downshift Rev Matching (the G37 Coupe is also available with a 6-speed manual transmission).

All 2009 G37 Coupes receive standard Scratch Shield paint (self-healing clearcoat finish). The 2009 G37 Coupe is available in four models – G37, G37 Journey, G37S Sport 6MT and G37x AWD – each with standard 330-horsepower 3.7-liter VQ-series V6 with VVEL technology. It goes on sale in September 2008

      Because the gas mileage of the G35 wasn't bad enough???
        • 7 Years Ago
        FYI, the 3.7 gets better mileage that the 3.5 because of the VVL System.

        Plus it has 2 extra gears now.
        • 7 Years Ago
        I agree, I would like to see something like the Lexus IS approach where you can get a smaller 2.x liter engine, or even like an A4 where there is a turbo 4 option.
        • 7 Years Ago
        There should be no change from going from VQ35hr to VQ37vvel.

        There should be a small improvement (without an axle ratio change. Come on Nissan, let top speed be achieved in 5th 175@7000) from moving from 5 speed auto to 7 speed auto.

        6th 0.8622, 7th gear is 0.7715, the old 5 was 0.839

      I likethe upgrade, but what about $$

      I think Infiniti needs to bring about a smaller model and have it start at $28.5k. of course it better be RWd adn about 400lbs lighter than the G.

      I like my 03 G35 auto right now, but I do feel that it's missing a gear especially when traveling over 65mph, the rev's should loose about 300-400rpm or so
        • 7 Years Ago
        That's where the 350Z comes in.
      • 7 Years Ago
      I'd buy one over a 335i any day.
      • 7 Years Ago
      Awesome! This is going to be a great car. I hope they put the new 7 speed auto in it. I would buy this car in a second if I had the moollah. If it had direct injection and a fold down rear seat the car would be PERFECT!

      so seeing as how ATESSA ET-S is the same AWD system as on the (old) GT-Rs (probably R32, newer ones are ATESSA ET-S Pro I believe), could the G37x coupe have similar at the limit driving behavior as the GT-R?

      ATESSA ET-S is rear biased, but once the rears starts sliding, power is moved to the fronts as well, giving the effect of being "pulled out" of an oversteer situation naturally.

      This is one of the reasons why the GT-R (older ones too) are so great, and would be fantastic to have on any car. But since there already was a G35x at some point and no review ever mentioned anything positive about that, is this incarnation of ATESSA ET-S not set up like the GT-Rs or something (maybe more front biased?)
        • 7 Years Ago

        Please note that this is the G37x we are talking about, not the G35.

        ETS is the designation given to the GT-R rear transaxle. It has very little in common with the center-differential setup on the G35.

        IF (and I stress IF) the G37 switches to the rear transaxle setup with secondary propulsion shaft (like the GT-Rs) and replaces the rear-biased active center differentiol (like the G35), this could be a MAJOR performance improvement.

        Even with the 'slushbox', a G37 with that system could perform 90% as well as an R34 GT-R. That would be effing astounding.
        • 7 Years Ago
        Nissan takes out the VSLD (speed sensitive differential) when you get the G35x. (they did for '08)

        There doesn't seem to be any mechanical incompatibilities to having that rear differential and the clutch coupled front axle.
        If it was a torque sensitive differential, I could see Nissan's rationale for removal.

        Maybe one would be able to pick one up cheap ($500), if someone decides to 'upgrade' to a torque sensitive differential. (say a rear drive stick car)
        • 7 Years Ago
        Oh. Here's the Quadra-Drive link.


        Rear-biased and with full left to right limited-slip differentials (and not that fake electronic crap either!).
        • 7 Years Ago
        Scratch that about the G35 having a rear-bias active center diff. I was thinking Quattro.

        Its a front-bias transaxle with transfer case to rear currently. That's even worse.

        Even if its the mid-mounted transmission with rear LSD (likely for a 7-speed automatic) and a transfer case back to the front (like the R32-R34 GT-Rs).

        Fearless Fred:
        Note the paragraph break in there.

        I made two different points.

        1. The G35x doesn't drive like a Skyline, or indeed special at all.
        2. It has a slushbox.

        Neither of those is likely to make you say "OMG, this car is a Skyline in disguise!".

        I looked for details, there's no info on the ATTESA system used in the G35x. Yes, it has the same name, but then again Audi uses quattro to refer to two wildly different systems too.

        Can you even find info that says the G35x even has a limited slip diff in the rear? I can't. It's too bad companies aren't more forthcoming about how their AWD systems work.
        • 7 Years Ago
        huh? what does a "slushbox" have to do with driving dynamics? If I am cornering, it doesn't matter whether I am driving a manual in 3rd gear, or whether I have an auto (with semi-manual controls, which any sporty car has) held in 3d gear, they will both have identical at the limit behavior.

        I know the G35x wasn't great. That's exactly what I am asking... giving that it has the GT-Rs AWD system, WHY isn't it any better?
        • 7 Years Ago
        The G35 and G37 ARE Skylines. ;)
      • 7 Years Ago
      Finally. VQ fanatics re-joice.
      • 7 Years Ago
      And do we also get the FX37 and EX 37?
        • 7 Years Ago
        There is a FX50 if the FX35 isn't enough.
      • 7 Years Ago
      Good to hear. I feel the sedan looks better than the coupe, so putting the 3.7L in the sedan means I'll probably be looking to buy one in a couple years.
      • 7 Years Ago
      Shold this not be in the Infiniti section?
      • 7 Years Ago
      hopefully the 370z will come with an ATESSA AWD too. I would buy one.
      • 7 Years Ago
      An infiniti fitted with the GTR's AWD, SWEET!
        • 7 Years Ago
        X2 and the sharper looks to boot! I'm liking this Alot. As infiniti gets better and better acura looks worse and worse- must be some odd ratio going on.
      • 7 Years Ago
      G37x coupe? I never understood why that didn't come out with the G35x sedan.

      What I want to know is whether or not the G37x coupe will have the 6MT. Because, if it's only available as an automatic...I see failure on the horizon.
        • 7 Years Ago
        Because a G37x coupe will be VERY front heavy
        It is already 54/46, so 56/44
