Nissan stoked excitement by revealing the Nissan Z Proto last year, but the concept left many wondering what the production Z car would look like. Well, thanks to an Australian patent filing, we now have some validation the production Nissan Z car will look a lot like the concept.

The patent filing shows us nearly every view of the exterior of what is clearly a Z car. To the untrained eye the filing may even look exactly like the Z Proto, but there are some differences. Notably, theres keyholes in the doors and liftgate of the patent filing, a requirement in case the car’s battery dies. The drawings also show cutouts for reflectors, a regulatory requirement in many countries. Lastly, the headlights are slightly larger than the concepts, while sensors are visible in the lower air intake area. All of these are clear indicators we’re looking at a production car, not the concept.

Nissan is expected to call the redesigned Z car the 2022 Nissan 400Z. While it will sport this heritage-inspired exterior and a new name, it will ride on the 370Z’s platform. Power is expected to come from a twin-turbocharged 3.0-liter V-6 with around 400 horsepower. A higher-output version of the V-6 is expected to find its way into a 400Z NISMO.

The 400Z is expected to start around $40,000 when it arrives on the market. The exact launch timing of the 400Z is still unknown, but a full reveal of the production car is expected this year.
