About Nissan Leopard Ultima X


The Nissan Leopard Ultima X was a concept car that made its debut at The Tokyo Motor Show in 1987.

This Leopard concept NEVER made it to production. The prominent features that the Ultima X would showcase was the convertible feature and a removable hardtop.

The speculation was this concept  eventually became Infiniti M30 convertible. With limited pictures and information we have today, it looks like there was considerable thought into this model.

The Ultima X was debuted in 1987, so this would fall under the previous term leopard (Zenki). So the dash is similar to that. Notice that there are differences with the equipment and color/material of the seats.


Very unique back seat set up. Very clean looking boot/cover for the retracted top.


The removable hard top is a very cool idea. I’ve seen them on various cars and would be nice to have one on an M30 convertible.

With this being the Ultima, it would be powered by a VG30DE mated with a 4 speed automatic transmission.

Even 30 years later, the idea of a Zenki convertible is amazing welcomed. In Japan, the M30 convertible is wanted and prized, but there is limited supply there and price is high!
