Three V6 petrol engines and one V8 will make up the range, all matched to an eight-speed automatic transmission.
The entry-level 3.0 litre V6 makes 190kW and 304Nm while the slightly larger 3.3 litre unit produces 208kW and 348Nm.
The current 3.8 litre V6 and 5.0 litre V8 will continue to be available, with figures of 232kW and 397Nm for the V6 and 313kW and 520Nm for the V8.
Each engine can propel the Genesis to its top speed of 240km/h, except the entry-level 3.0 litre which is only rated at 230km/h. The V8 handles the 0-100km/h sprint in 5.4 seconds.
Rear-wheel-drive will be standard fitment to the new Genesis, but the luxury sedan will be the first model to feature Hyundai’s new HTRAC all-wheel-drive system in selected markets.
The new Genesis is 4mm longer (4990mm) and 5mm taller (1480mm) than its predecessor, while the wheelbase has grown 75mm to 3010mm in the interests of rear seat comfort.
New features for the 2014 Genesis include CO2 cabin sensor control, Blind Spot Detection system with integrated Head-Up Display, Automatic Emergency Braking (AEB) and radar-guided cruise control.
Hyundai’s Korean order book is already open, with the carmaker taking 3500 orders on the first day.
The sales department is hoping 62,000 units will sell in 2014, split almost 50/50 between Korea and other global markets including China, the USA and Russia along with parts of Europe and the Middle East.
While the new Genesis Coupe will be offered for sale in Australia, Hyundai is still to decide if the sedan will appear in local showrooms.
