Nissan GTR

http://www.gtrnissan.com/


Engine
• VR-series twin-turbocharged 3.8-liter V6.
480 hp @ 6,800 rpm. 430 lb-ft torque @ 3,200–5,200 rpm.
• Dual overhead camshafts with variable intake-valve timing.
• Cast aluminum cylinder block with high-endurance/low-friction plasma-sprayed bores.
• IHI twin turbochargers, one per cylinder bank.
• Pressurized lubrication system with thermostatically controlled cooling.
Drivetrain
• ATTESA ET-S All-Wheel Drive (AWD) with independent rear-mounted transaxle integrating transmission, differential and AWD transfer case.
• Rigid, lightweight carbon-composite driveshaft between engine and transaxle.
• Electronic traction control plus 1.5-way mechanically locking rear differential.
• Vehicle Dynamics Control (VDC-R) with three driver-selectable settings: Normal (for daily driving, controls brakes and engine output), R-Mode (for ultimate performance, utilizes AWD torque distribution for additional vehicle stability) and Off (driver does not want the help of the system).
• Hill Start Assist prevents rollback when starting on an incline.
DisclaimerVDC-R cannot prevent accidents due to abrupt steering, carelessness, or dangerous driving techniques. Always drive safely.

Transmission
• 6-speed Dual Clutch Transmission with three driver-selectable modes: Normal (for maximum smoothness and efficiency), Snow (for gentler starting and shifting on slippery surfaces), and R mode (for maximum performance with fastest shifts).
• Fully automatic shifting or full sequential manual control via gearshift or steering wheel-mounted paddle shifters.
• Dual clutch design changes gears in less than 0.5 second (0.2 second in R mode).
• Downshift Rev Matching (DRM).
• Predictive pre-shift control (in R mode) based on throttle position, vehicle speed, braking and other information.

Wheels and Tires
• 20 x 9.5" (front) and 20 x 10.5" (rear) super-lightweight forged-aluminum wheels with Gunmetal Gray finish.
• Exclusively developed nitrogen-filled Bridgestone® RE070A high-capacity run-flat summer tires, 255/40R20 front and 285/35R20 rear.
• Tire Pressure Monitoring System (TPMS).
• Optional exclusively developed nitrogen-filled Dunlop® run-flat all-season tires, 255/40R20 front and 285/35R20 rear (includes Bright Silver wheels).
Brakes
• Brembo® 4-wheel disc brakes with 4-wheel Antilock Braking System (ABS), Brake Assist, Electronic Brakeforce Distribution and Preview Braking.
• Two-piece floating-rotor 15-inch front and rear discs with diamond-pattern internal ventilation.
• 6-piston front/4-piston rear monoblock calipers.

Steering
• Rack-and-pinion steering with vehicle-speed-sensitive power assist.
• 2.6 steering-wheel turns lock-to-lock.
Suspension
• 4-wheel independent suspension with Bilstein® DampTronic system with three driver-selectable modes: Normal/Sport (for automatic electronic control of damping), Comfort (for maximum ride comfort), and R mode (engages maximum damping rate for high-performance cornering).
• Electronically controlled variable-rate shock absorbers. High-accuracy progressive-rate coil springs.
• Front double-wishbone/rear multi-link configuration with aluminum members and rigid aluminum subframes.
• Hollow front and rear stabilizer bars.

Body/Chassis
• Exclusive Premium Midship platform with jig-welded hybrid unibody.
• Aluminum hood, trunk and door skins. Die-cast aluminum door structures.
• Carbon-reinforced front crossmember/radiator support.


wow. but can someone explain the nitrogen filled tires?

Nitrogen is not as sensitive to temperature and therefore pressure change the same way air is. It holds a given pressure more steadily and will not fluctuate as much due to ambient temperature change or the vehicle being driven.

Specs sound like it could be a fun drive

The nitrogen expands/contracts less over temperature changes, for more consistent tire pressure. Don't forget that your 'regular' air is already 75%-ish nitrogen. Not particularly useful for day-to-day driving, but nice for the track.

EDIT: Wait, am I making stuff up? I thought that was the main reason, but here's a link with more.

makes sense about the nitrogen. and its funny because i just finished reading an article in Car & Driver about the new GTR and that is the reasoning they gave for nitrogen. by the way, its a good issue. i suggest that you guys pick it up. nissan gtr, porsche caymen gtr (tuner built) comparison between C63 AMG, RS4, and new M3, all around good read so far.

I can't wait to see what the tuners will do with this, sounds like a beast from the factory. Any mention of price?

estimated price of $85,000. not too bad considering the performance. and according to the article, "Nissandevelopment team proudly claims it has made the ECU tamper-proof" we will see how long that lasts
