Cutting directly to what matters to those who worship the numbers: The GT-R’s 3.8-liter twin-turbo V-6 now makes 600 horsepower and 480 pound-feet of torque. maximum power gets boosted—literally—with the larger-diameter (and we assume, higher-boost) turbos that are used for racing. Breathing has been improved, and each individual cylinder gets its own timing control. The exhaust system is new as well. And altogether, max power arrives at 6,800 rpm (versus 6,400 rpm).
Race-derived suspension changes
With the introduction of a modified suspension setup from Nissan’s 2012 Nurburgring 24 Hours road-race car, the GT-R NISMO should handle even better than before, without a significant sacrifice in ride.
To the contrary, the automaker actually points to improved refinement and reduced road noise and harshness. Better body control and reduced roll were achieved with a larger 17.3-inch hollow rear anti-roll bar; and in front, the double-wishbone suspension has been fitted with links that increase the castor trail—to aid high-speed stability, and precision in high-G cornering. Meanwhile, special springs and custom-developed Bilstein DampTronic dampers are also used in front and in back to tune this model’s handling and ride.

Nissan has helped back up these changes in suspension by enhancing the body structure—with new adhesive bonding that brings better overall rigidity, and better suspension response under full load.
Inside, the 2015 GT-R NISMO gets Alcantara trim for the steering wheel, with a three-spoke design for the tiller plus a red center mark and red stitching. There’s also ‘discreet red stitching’ for the seats, door trim, and center console. Japanese and Euro-market models will get carbon fiber-backed Recaro seats; we’re not yet sure if U.S.-market seats will change.
2015 Nissan GT-R NISMOWe’re expecting that the GT-R NISMO will continue offering its extensive, multi-screen array of performance-oriented gauges and displays—including such things as G-forces.
And through a connected services advanced performance telemetry system, drivers can download and see their on-track performance.

Matte look equals 'imposing muscularity'
Changes to the GT-R NISMO are subtle; although enthusiasts in the know are going to pick them out right away. The GT-R Nismo rolls on GT500 race-inspired black six-spoke wheels, while the Nismo is offered in a new Dark Matte Grey hue that is, according to Nissan “accentuating the car’s imposing exterior muscularity.”
There’s also a new trunk-mounted spoiler in back and tapered/extended bumper, while the front end gets a wider new carbon bumper and lower valance/cover—with these changes altogether reducing the coefficient of drag to 0.27.
Last, but definitely not least for those intending to explore the GT-R’s boundaries: Improvements in aerodynamics altogether generate an additional 220 pounds of downforce at 186 mph.
