And while Nissan isn't saying, it is likely that we can expect to see a version of this concept to debut as the US market's next-generation Maxima sedan.
Due to debut later this year, the new Maxima will enter the company's American range above the existing Altima sedan, which hit the Australian market in 2013.
In concept form, the Sport Sedan concept is powered by Nissan's 225kW 3.5 litre petrol V6, sending power to the front wheels through an Xtronic CVT automatic transmission.
Standard fare for a volume-selling family sedan, then, and about right for the Maxima line.
It's unclear however if we can expect to see the new Maxima in Australia. At 4870mm, this Sport Sedan Concept is only 10mm longer than the Altima, although its 2825mm wheelbase is markedly longer than the Altima's 2776mm.
Likewise, Nissan Australia's discontinued Maxima - based on the earlier Japanese-market Teana sedan - was 4850mm long, riding on a 2775mm wheelbase.
(That second-generation Teana has now been replaced in Japan by a new third-gen model: the same car sold in Australia and the US as the Altima.)
Ultimately, the new Maxima's Australia potential will come down to two factors: a business case for a new large sedan above the already sizeable Altima, and a right-hand-drive production schedule.
If nothing else, we can expect to see the Sport Sedan Concept's styling in future Nissan Australia models, including the next Altima - and possibly an update to the current model.
"Our new design direction mirrors the strength, power and capabilities of the engineering and innovation that serves as the foundation of every Nissan vehicle," Nissan design chief Shiro Nakamura said.
"Nissan is a brand for people seeking bold and passionate experiences, and who are willing to make choices outside of traditional boundaries. That's why Nissan is committed to breaking new ground in automotive design, as expressed in the stunning new Sport Sedan Concept."
