As another model year approaches for the Nissan GT-R, another round of improvements are being made. Rather than simply bumping up the horsepower, Nissan has decided to make refining changes to its supercar, which was recently unveiled in JDM spec for the 2013 model year.

Rather than milking more power out of the 3.8-liter twin-turbo V6, Nissan fine-tuned the engine with new injectors for quicker response, a baffle added in the oil pan to maintain constant oil pressure during enthusiastic driving and an improved turbo bypass valve for better acceleration at higher speeds. Nissan also optimized the car's handling potential by giving it a lower center of gravity, new shocks and stabilizers, and reinforcements in the dash giving the car a more rigid structure. Finally, the Premium Edition model adds a new Semiarinin leather and will even offer custom colors for the interior.

We've already seen a left-hand drive GT-R testing at the Nürburgring, so we will likely see these changes in the US for the 2014 model year, where it will be interesting to see whether or not the car's price will finally break into the six-figure range. The 2013 GT-R goes on sale in Japan later this month, but we'll have to wait until at least January to see the updated car here.

Until then, scroll down for a couple videos about the testing and development of the revised GT-R as well as Nissan's press release for the JDM model.

2013 Nissan GT-R in Japan: Supercar Performance Elevated

The following press information has been released by Nissan Motor Company Ltd. with images showing the 2013 model year Japanese market GT-R. Specifications of the U.S. market 2014 model year GT-R will be announced at a later date.

YOKOHAMA, Japan – Nissan Motor Co., Ltd. today announced the launch of the 2013 model year Nissan GT-R, which goes on sale in Japan on November 19 at Nissan dealers nationwide.

The 2013 model year Japanese market Nissan GT-R features enhancements throughout the vehicle for increased performance, improved ride and handling, and greater customization.

Already considered a legendary supercar, the 2013 GT-R received evolutionary design and engineering enhancements based on feedback acquired from competing in the 24-Hours of Nürburgring race earlier this year. Notable modifications include improved engine response in both the mid- and upper-rpm rev range, increased body rigidity, and specification changes to the shock absorbers, springs and front stabilizer. As a result, the vehicle's overall performance is dramatically increased, high-speed stability improved and ride quality is more refined. Additionally, a Premium Edition version will be offered that features rich Semiarinin leather and custom-colored interior as fashonable interior package, further enhancing the sense of quality within the cabin.

The 2013 GT-R model will also be available in North America, Europe, and then subsequently to other regions from January 2013 onwards.

2013 MY NISSAN GT-R Overview


1. Mechanical Features

Engine
Sharper mid-range engine response and improved high-end acceleration.

The incorporation of high-output injectors that more precisely control fuel injection improve mid-range engine response and acceleration at higher rpms.

Specially-developed orifice to the relief valve have been added to the turbocharger bypass; these suppress the rapid decrease of the forced injection pressure, helping to sustain acceleration at high rpms.

By adding a specially-designed baffle plate to the oil pan, oil pressure is better stabilized while rotational friction within the oil pan is reduced, especially during high-performance driving.

Motul Competition Oil is offered as an engine oil option at Nissan dealers due to the many requests from GT-R customers who frequently drive their cars at circuit.

Chassis
Glued-to-the-ground handling and rock-solid stability at super high speeds.

After meticulously measuring the roll center of a GT-R while in motion, Nissan engineers lowered the vehicle's center of gravity in accordance with the deflection of the suspension bushings and tires. The specifications of the shock absorbers and front stabilizer have also been modified.

Cam bolts have been installed on the front suspension to improve camber accuracy and maintainability of alignment settings.

The torque from the driveshaft to the hub bearings was increased to improve reliability in high-stress situations, such as competition (track) driving.

Body
Improved driving stability and steering response.

Reinforcements were added at two locations in the dash panel bar and instrument panel member, resulting in improved suspension performance and increased body rigidity.


2. Interior

Pure Edition
The quality level of the interior has been improved by changing the color of the stitching and adopting a thicker seam on the instrument panel and door trim.

Black Edition
An attractive red-and-black color combination steering wheel increases the car's sporty flair.

RECARO carbon bucket seats are available as a factory installed option.

Premium Edition
A new two-tone interior color of Amber Red and Black adds style to the interior as option for fashionable interior package.

Hand-stitched genuine semi-aniline leather front seats have been added.


3. Specifications/ equipment

Carbon-fiber rear spoiler and lightweight aluminum-alloy forged RAYS® wheels are available as a factory installed option (Black Edition).

Rear View Monitor comes as standard equipment on the Black and Premium edition models.

Convenient "side knobs" on the left and right sides of both front seats improve usability when seatbacks are pushed forward (all models).

      "Nissan also optimized the car's handling potential by giving it a lower center of gravity" Nissan lowered the roll center, not the center of gravity. The roll center is the mechanical axis about which the car rotates as it leans side-to-side. By changing the suspension geometry, they lowered the roll center, meaning that more weight and/or force is required the make the car lean now. Or put another way, the same cornering forces now cause less body lean than before.

      Skyline can prattle on all day about how the GT-R's price has ballooned, but frankly, it's still one of the best values on the market. There's maybe 1 production car, if that, that could beat a GT-R around a track and carry more people/luggage.

        It's worth noting, of course, that the R35 GTR is no longer a Skyline.

        You really think people are buying the GT-R to put 4 people in it? I don't, those rear seats are torturous. It might as well be a 911 in that way. I almost bought a GT-R, I didn't because only the entry price is a good value. The running costs are similar to much more expensive cars due to the transmission/gearbox fluid scam. I'm somewhat convinced Nissan is just setting aside part of the purchase price and getting it back from you $2K every 10,000-20,000 miles. When you look at this, a Corvette ZR1, while similar in price (or more expensive) up front is actually a lot cheaper to own.

      "Semiarinin"? Did we cut and paste from the Jinglish press release? I think we mean "semi-aniline"...

      the gtr is tuned for only high speed driving and while you doing hi speed can have a conversation, because its so quiet. ok obviously i'm a 911 but lets not even bring that into this. i've driven a gtr hard and its so boring if i want a little steering feedback and a super quiet interior ill buy an audi s5 but the s5 is still more to drive plus you wont look like a dork. plus with the money you save you can buy a bzr for the track. sort of sad the gtr has turned into this lap time generator i really do love the previous ones, the r34, r33 and r32 even then but now all they want is to beat 911 turbos on the nurburgring, but let me tell you a secret the gtr may be a better at a time attack then they baby 911's but when you're on a track for an hour or more, a 911 tires wear out less and there no break fade the gtr kills heavy. riginal s45.

        It's tough to read your comment when it lacks basic sentence structure.

        So... you're suggesting an S5 and a BRZ is better than having one fast daily driver GT-R... While claiming you like Porsche... Wouldn't your rant also apply to the 911?

      For a "GT cruiser," does itnstill have a laughably stiff suspension?

      7:19.1 is blisteringly fast for a GT cruiser. Kudos once again, Nissan!

      The best bang for the buck supercar just keeps getting better. While it's interior was superior to that of a ZR-1, it lacked a bit from Porsche. Now it looks like things are on par. That's certainly impressive the time drop on that lap. Especially after the interior upgrade, I can't see buying a Porsche other than for the emblem, or if you just genuinely like the looks more. Even then, styling is always subjective anyways. Some may like the edgy GT-R more than the rounded Porsche.

      funny, they compare their own laptimes to "Sport Auto" laptimes, just like the fanboys do.
