The newest round of unconfirmed, yet plausible information comes courtesy of the GTChannel, where they've reported a number of facts that we've listed in all their bullet-point glory after the jump.
• The chassis designation will be CBA-R35, the last bit continuing the long-held R-number moniker of previous generations
• Three trim levels: Base, Black Edition and Premium – all equipped with the same VR38DETT twin-turbocharged 3.8-liter V6
• Everything fit within the engine will be forged
• Six exterior colors: Titanium Gray, Dark Metal Blue, Super Black, Vibrant Red, Ultimate Metal Silver and White Pearl, the last two are classified as premium paints and will command a few extra bucks.
• Two interior colors: Black or Gray, with black appropriately being the only color available on the "Black Edition"
• Rays forged wheels (likely sized 18-inches), coated in chrome and wrapped in Dunlop Sports tires. An upgraded tire and wheel package with gunmetal Rays wheels will be available on the base model, and standard on Black and Premium vehicles.
• Anti-theft and Bose sound will be an option on the base and Black versions, while standard in Premium trim.
• SRS curtain and side airbags will be an option on all three models
As for dimensions, it's been pretty much confirmed that the GT-R will be 4,650mm long (183-inches), with a wheelbase of 2,800 mm (110-inches) and a width of 1,920mm (75.6-inches). Power is still expected to be in the 450 to 550 HP arena, with a curb weight somewhere in the neighborhood of 3,500 lbs.
We'll be on hand when the veil is lifted in Tokyo at the end of next month, and we'll finally be able to see what five years of development has finally wrought.
