Currently used in the Carnival people-mover, for fitment to K9 the Kia engineers boosted the Lambda V6's power output, raised its efficiency and enhanced its refinement.
A new-generation direct injection 3.8-litre V6 engine with 245kW output will join the global engine line-up next year.
An all-new eight-speed automatic transmission is standard with a wide spread of gear ratios allowing brisk acceleration and high-speed refinement, while shift-by-wire (SBW) technology with a joystick control delivers fast, smooth gear changes.
The ultra-stiff bodyshell, electronically controlled air suspension with five-link front and rear suspension geometry provide sophisticated ride and handling characteristics.
Four driving modes (Eco, Normal, Sport and Snow) enable the driver to choose a preferred set-up of suspension, steering, engine and transmission ideal for various road conditions or driving styles.
"K9 is all about elegant simplicity, balanced proportions and simple surfaces," said Kia's chief design officer, Peter Schreyer.
"The class-leading long wheelbase, the prestige distance, large wheels, sharply upright short overhangs and a long sweeping shoulder line all work together in a harmony to give K9 a sporty, athletic proportion and a confident stance quintessential to a premium large rear-wheel drive vehicle.
"K9 is a clear signal of our intention and determination to compete head-to-head with the European luxury brands.
The all-new saloon will premiere a range of advanced luxury features and technologies, including fully adaptive all-LED headlamps, Lane Departure Warning System (LDWS), radar-based Blind-Spot Detection (BSD), a 17-speaker Lexicon (by Harman) sound system, Smart Cruise Control (SCC) and an Around-View Monitor (AVM) with four cameras.
Premium features include a 12.3-inch full size Thin Film Transistor (TFT) LCD cluster, an HUD (head-up display) and twin 9.2-inch monitors to entertain rear-seat occupants.
Smart Cruise Control (SCC) which adjusts speed to maintain the distance from the vehicle ahead is also standard.
The luxury limousine status supported by a "VIP" option will offer twin heated and ventilated rear seats with a reclining backrest, sliding cushion and lower leg support for the "nearside" seat, together with a front passenger seat that slides forward when not being used.
