Japanese magazine CarTop is speculating that Infiniti could be developing a new range-topping sedan based on the 2009 Nissan GT-R. Allegedly, the sedan could go on sale as early as 2011. But how similar would it really be to Godzilla? And what should we call Godzilla with two extra doors anyhow?

According to CarTop, the 2011 Infiniti GT-R would use a stretched version of the GT-R's chassis, complete with its whiz-bang AWD system, a tuned version of the 3.8-liter twin-turbo V6 producing nearly 500 HP, and share the same Xtronic CVT. Pricing would be about 20% higher, bringing the sedan in at around $85,000 (before speculation) on this side of the Pacific.

Jalopnik Snap Judgment: This is probably just idle speculation. But, think of the possibility! Such a sedan would give Infiniti the range-topper it desperately needs, capable of defeating cars like the 2011 BMW M5 and Mercedes E63 AMG on their own turf, the 'Ring. A less aggressively styled four-door could be the ultimate Q-car and finally propel Nissan's luxury brand into direct competition with the Germans while simultaneously leaving Lexus to eat its dust. On the other hand, remember what happened the last time Nissan stretched its supercar chassis, added two doors and installed an Infiniti badge? The thirsty, cramped, and unspectacular J30.
