Nissan has launched its factory backed Nismo enhanced version of the 350Z to the Japanese domestic market, known locally as the Fairlady Z. Major changes over the regular car include the more powerful, next-generation version of the company’s global VQ 3.5L V6 engine, refined hood, race-style aero parts and new trim and paint schemes.

The interior’s Nismo package features Alcantara-trimmed seats, revised door trim, shift knob and instruments, as well as optional aluminum pedals. The Nismo Z was developed using extensive racing expertise gained through competing in Japan’s SUPER GT and with the aid of Autech and Nissan’s works team.

Nissan will also be displaying an even higher-performance 380RS-Competition version (pictured above) for private race teams or even road use at this weekend’s Tokyo Auto salon. The 380RS comes with a race-tested, long-stroke 3.8L HR-series V6 engine developing 395hp and 311 lb-ft. of torque. Other features include a unique 6-speed close-ratio gearbox, heavy-duty clutch, Brembo 6-piston calipers, lightweight carbon-fiber doors and hood, perspex windows, roll bar and racing bucket-seats. Only 300 copies are expected to be made with a price tag of $221,332 for Japan only.

Finally, Nissan has launched the 2007 edition of the Z Coupe and Roadster. The major change is the VQ35HR engine that has nearly 80% of major parts redesigned over the former VQ35DE. The car now comes with 313hp on tap combined with 358Nm of torque. Visually, the car features a new hood design closely resembling that of the first generation Fairlady Z and three new colors.
