Peter Fadeyev, the general manager of corporate communications at Infiniti Australia, told Car Advice that the company "hopes to introduce the production version of the Q60 Concept [in Australia] around the fourth quarter of 2016".
The company's North American arm confirmed earlier today that the new Q60 will begin heading into American showrooms from around June 2016.
Infiniti has yet to outline the drivetrains it will offer in the new coupe, but it seems likely that most options will be shared with the Q50 sedan. As with the current coupe, the new Q60 is based on the company's mainstream rear-wheel drive sedan, in this case the Q50.
Currently Australia-bound Q50 sedans are powered by either a 155kW/350Nm 2.0-litre turbocharged four-cylinder petrol engine, a 125kW/400Nm 2.2-litre turbo-diesel, or a 268kW/546Nm hybrid with a V6 petrol motor at its core. In other markets, the Q50 is also available with a 245kW 3.7-litre V6.
The Q60 Concept featured a twin-turbo direct-injection 3.0-litre V6 with around 336kW of power, and this motor is said to be a preview of a new range of engines coming to the marque.
At present, the Q60 range is available solely with a 235kW/360Nm 3.7-litre V6 with a seven-speed automatic tied to the rear wheels. The current Q60 coupe and convertible were launched in Australia in 2012, back when the vehicle was known as the G.
As with other models in the Infiniti lineup, the Q60, and its G coupe and convertible predecessors, has been a slow seller with just 69 finding new homes in 2014. That's well behind the 642 Audi A5s, 1851 Mercedes-Benz C-Class and 2201 BMW 4 Series two-doors sold last year.
Update (midday 12/8/2015): Included approximate Australian launch date for the new Q60.
