Automakers try their darnedest to keep future vehicles secret until they're good and ready to reveal them. But more often than not, something leaks. One of the best sources of future vehicle information turns out to be government officials, who have been known – whether through regulation or by accident – to make public the private plans revealed to them by automakers. Vice President Joe Biden's notoriously loose lips are one example; copyright offices are another.

In this case, potential plans for an upcoming new line from Infiniti have been revealed under the name JX. According to Car and Driver, Nissan has applied to trademark the names JX20, JX25, JX25h and JX30 at both the US and Canadian federal patent and trademark offices. Just what these model names signify is a matter of speculation, but if the existing EX, FX and QX are anything to go by, we should be looking at a crossover.

The numeric designations suggest the potential availability of a 2.0-liter four, a 2.5-liter V6, a hybrid and a 3.0-liter V6 (potentially a diesel), indicating that the JX would likely be rather compact in size. Sources speculate on a possible premium variant of the quirky Nissan Juke. But Nissan, for its part, reportedly claims the trademark registrations – like the XW35, PX35 and DX35 filed previously – are precautionary, registered in the event they should need them. We'll just have to wait and see.
