In terms of design, both the K550 and K750 don't stray far from the somewhat generic styling already seen on the H600 - penned by iconic Italian design house, Pininfarina - including the slim headlights extending into the trapezoidal grille, though there are slight variations between the two when it comes to shape and size.
The smaller K550 - which is reportedly about the same size as a Mercedes-Benz GLC - sports a slimmer version of HKG's corporate face, while the larger K750 has a taller and wider grille, looking almost like a gaping mouth.

More noticeable differences are visible from the sides and the rear, with the smaller model adopting a more athletic, fastback aesthetic, while the K750 taking a more conventional SUV shape and a more prominent glasshouse.
Inside, the family resemblance continues, with both models featuring an array of screens, leather interior trim and decorative metal highlights. However, the K750 adds a second-tier screen above the main instrument and infotainment screens which almosts acts as a head-up display.

Another difference between the two SUVs is that the K550 is pitched as a four or five-seater while the K750 is a six or seven seater.
The K550 in the images is configured with a fixed centre console in the second row - making it a four-pew affair - while the K750 show car features three rows of two seats, the rear rows both featuring captain's chairs.
Both vehicles also appear to offer healthy amounts of rear legroom, which is somewhat vital for the Chinese market.
While the company hasn't disclosed what exactly powers either model, Pininfarina says both utilise a "micro-turbine" hybrid system, similar to that used in the H600 sedan.
In the sedan concept, the powertrain was claimed to produce over 500kW, and a range of over 1000km thanks to the range extender.
Considering the growing popularity of SUVs, expect both of the Shanghai concepts to spawn similarly-styled production versions at the turn of the decade as well.
