The Nissan GT-R


                                             The Nissan GT-R.
pricey exotics. Packed with electronic handling and launch control aids, the GT-R - affectionately nicknamed "Godzilla" by enthusiasts - uses advanced technology to overcome its substantial curb weight and offer agile responses along with truly breathtaking acceleration figures.
The centerpiece of the GT-R is its powerplant, a twin-turbocharged and direct-injected 3.8-liter V6 that pumps out 545 horsepower and 463 lb-ft of torque. The new model year has brought a number of minor revisions to the motor: high-output injectors designed to create improve mid-range punch; a reworked turbocharger bypass in order to help sustain acceleration at high RPMs; and a new baffle plate in the oil pan to better stabilize oil pressure.

The results don't change the GT-R's acceleration figures - which are already impressively brief - but they do help make the motor more tractable during performance driving. For the record, the GT-R can sprint from zero-to-60 mph in 2.9 seconds and achieve the quarter mile in a hair over eleven ticks.
Helping Godzilla achieve those figures is all-wheel-drive and a six-speed dual-clutch automated-manual that can rip off downshifts in the blink of an eye. Like other dual-clutch transmissions it can be slightly unrefined in low-speed driving, but most buyers will find that a small price to pay for the incredible performance it facilitates.

The GT-R is already widely considered as one of the best handling vehicles on the market, and the latest version promises to build on that reputation. On top of a host of recent upgrades, Nissan has made a number of improvements for the latest model year. Modifications to the shock absorbers and front stabilizer tighten up the handling, as do new dash panel reinforcements that increase body rigidity.
Japanese-spec models are unique in cardom in that they get an asymmetrical suspension set-up. To offset the added weight of the driver and the transfer case along with its driveshaft mounted on the right side of the car, the setup has a front left spring rate that is higher than the right one. At the same time, the diagonally-opposite right rear is reduced for a more balanced ride.

With straightforward gauges, a meaty steering wheel and well-bolstered seats, the cabin is a highly-focused driving environment. A center-mounted LCD screen designed in collaboration with Polyphony Digitial - makers of the popular Gran Turismo video game offers eleven separate pages of boost, g-force, acceleration, braking and steering info and even offers a recording function with playback.
High-quality leather and carbon fiber give the interior a premium feel, and a specially-designed 11-speaker Bose stereo - including two forward-facing woofers in the rear center armrest area - is a treat for audiophiles.

Though it's advertised as a 2+2, the GT-R is in truth suitable for two occupants only - the rear seats are best left to mortal enemies and luggage.
Aside from minor trim changes, the biggest news inside for the latest model year is a newly available Premium Interior Package that includes Red Amber semi-aniline leather upholstery along with red Amber accents on the instrument panel, steering wheel, door trim, armrests and shift knob.

Nissan GT-R


                                       Nissan GT-R.

While everyone else has been tinkering around, waiting to discover the next new detail on the 2012 Nissan GT-R , AMS Performance has been working on a package for the GT-R R35 that will just blow you away! The package is called the Alpha 9 and will catapult the standard 530hp found on the current GT-R R35 to a mind-boggling 650hp! Now, that’s an upgrade!
Adding this much extra power will inevitably bring better performance numbers. The Nissan GT-R is now capable of running the quarter mile in 10 seconds at 138 mph setting a new pump gas R35 GT-R 1/4 mile record. This does confuse us, however, because back in May we reported on a GT-R R35 that did the quarter mile in 9.62 seconds. We have to wonder if these two know about each other.

The Nissan GT-R is powered by the VR38DETT V6 engine, a 3,799 cc (3.8 L; 231.8 cu in) DOHC V6 with plasma transferred wire arc sprayed cylinder bores. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Models manufactured between 2007 and 2010 produce a manufacturer-claimed engine output of 492 PS (362 kW; 485 hp) at 6400 rpm and 434 lb·ft (588 N·m) at 3200–5200 rpm.The engine also meets California Air Resources Board Ultra Low Emission Vehicle (ULEV) standards.

Beginning in 2010, engine power and torque were upgraded to 390 kW (530 PS; 523 hp) at 6400 rpm and 612 N·m (451 lbf·ft) at 3200–6000 rpm respectively. Models produced in 2012 again featured improved engine output (404 kW (549 PS; 542 hp) at at 6400 rpm and 628 N·m (463 lbf·ft) at 3200–5800 rpm). In the near future, it is speculated that the GT-R might even be available as a hybrid.

A curb weight of 1,730 kg (3,800 lb) or 1,736 kg (3,830 lb) with side curtain airbags is achieved using a jig welded steel chassis with aluminum used for the hood, trunk, and doors. A rear mounted six-speed BorgWarner designed dual clutch semi-automatic transmission built by Aichi Machine Industry is used in conjunction with the ATTESA E-TS system to provide power to all four wheels and along with Nissan's Vehicle Dynamics Control (VDC-R) to aid in stability. Three shift modes can also be selected for various conditions.
