Expected to be called the 608, the car would become the new flagship for the French automaker - an unusual position for a car that, in concept form at least, resembles a people mover.
A productionised version of the HX1 would lose the concept's dramatic gullwing doors and integrated coffee machine(!), but could be powered by something not too dissimilar to the concept's diesel-electric hybrid powertrain.
The HX1 is designed around a 2.2 litre turbodiesel engine, supplemented by a torquey electric motor mounted on the rear axle.
Combined output of the diesel-electric system is supposedly 220kW, and by having the electric motor drive the rear wheels exclusively the HX1 is effectively all-wheel drive.
Production powertrains will likely comprise a range of lower-output diesels, along with a similar diesel-electric powerplant to the Peugeot 508 RXH.
At five metres long, the HX1/608 has roughly the same footprint as a Mercedes-Benz R-Class, albeit with a much lower-slung body.
It's unlikely whether the production version, if it eventuates, will keep the concept's unusual 4+2 seating arrangement, but there should be plenty of room in the rear for a couple of fold-out occasional seats.
The 607 was sold in Australia up until 2009, so there's a chance the rumoured 608 could make its way down under too. For now though, the 608's existence has yet to be acknowledged by Peugeot and we wouldn't expect to see a production model until late 2013.
