The luxury marque will also debut a new QX60 Hybrid model in New York, powered by its new supercharged 2.5 four-cylinder petrol engine mated to a 15kW electric motor and a CVT transmission. (Announced in 2011.)
Infiniti promises a combined output of 186kW, returning fuel consumption figures of around 9.0 l/100km - a 24 percent improvement over the 197kW petrol V6 model.
Energy for the electric motor is drawn from a lithium-ion battery pack, and while regenerative braking is featured, the system offers no all-electric driving option.
Importantly, the QX60 gives away no luggage space to the system, thanks to the battery pack sitting beneath the third seating row.
The carmaker isn't stopping there however, with plans announced in December revealing that Nissan and Infiniti will launch 15 new hybrid models over the next four years.
Infiniti Australia has yet to confirm any plans to bring the midsized JX/QX60 SUV to local showrooms.
Speaking with TMR last year, local boss Kevin Snell said that the new model is, at least, on the agenda.
"Whilst not yet confirmed for Australia, the JX is certainly on our radar and we are in discussions with Japan about the potential for introduction after our initial launch phase," Mr Snell said.
