Being shown as a one-off design study, Nissan says it's gauging consumer interest in such a model. If the automaker believes there's enough demand to justify it, the 370Z NISMO Roadster would join the 370Z NISMO Coupe model, taking the NISMO lineup to five models.

The powertrain and suspension setup is the familiar kit from the 370Z NISMO Coupe. Under the hood is a 3.7-liter V-6 engine rated at 350 horsepower and 276 pound-feet of torque. Power is sent to the rear wheels through a seven-speed automatic transmission. Why an automatic transmission you ask? Because Nissan says most of the Z roadsters are sold with an automatic transmission. So while the six-speed manual transmission from the 370Z NISMO Coupe would fit just fine, the concept features the automatic.

To keep things stiff there's a NISMO-branded strut tower under the hood along with NISMO-tuned four-wheel independent suspension. Special springs and stabilizer bars are swapped from the 370Z NISMO Coupe to the Roadster Concept, and a larger sport brakes help haul things back to legal speeds. There's also a limited-slip differential.

The exterior of the 370Z NISMO Roadster Concept features a power-folding fabric roof. Visually the NISMO Roadster stands out from the regular roadster thanks to a GT-R-inspired aerodynamic body kit. The NISMO red striping is in full effect, and the blacked out headlight bezels give this concept a bit of attitude. Out back there's a custom carbon fiber rear spoiler exclusive to the NISMO Roadster Concept. Wide 19-inch NISMO super-lightweight alloy wheels round out the package.

Inside the NISMO Roadster Concept are a pair of black Recaro leather-appointed seats with red stitching and off-white Ultrasuede inserts. A three-spoke NISMO steering wheel wrapped in Alcantara and leather sits just in front of the red NISMO tachometer.

For those seeking some technology along with their sports car, Nissan's navigation system and 7-inch color touchscreen infotainment system is fitted inside the NISMO Roadster Concept. For safety, a rearview camera is include as well.
