Korean brand sheds more light on the all-new sedan's available powertrains and technology suite, ahead of an Australian arrival later this year.

The new-generation Hyundai Sonata was first revealed a month ago, but now the manufacturer has release some preliminary details about its upcoming sedan.

After getting an early glimpse of the exterior and interior designs, we now have new information regarding the new Sonata's engine range along with available convenience and driver assistance technologies.

Two powertrains will be offered initially, both from Hyundai's 'Smartstream' engine family. The first is a 1.6-litre 'T-GDi' four-cylinder turbocharged petrol engine, making 134kW and 264Nm.

Additionally, buyers will be able to opt for a new 2.5-litre naturally-aspirated 'GDi' petrol engine, making 142kW and 245Nm. Both engine variants will be mated to an eight-speed automatic transmission as standard.

As for available tech, there's a range of new features that will be available with the next-gen Sonata.

First up is the new Digital Key, which is accessible via a dedicated smartphone app. Using Near Field Communication (NFC) technology, owners will be able to control vehicle functions through their phone, such as locking/unlocking the doors, or remotely starting the engine.

There's also a new 8.0-inch colour head-up display, which Hyundai says has a luminance of more than 10,000 candelas per square metre.

Drivers will be able to access a range of upgraded assistance and active safety technologies, which the company claims give the Sonata Level 2 autonomous driving capabilities.

Available features include autonomous emergency braking with pedestrian and cyclist detection, Safety Exit Assist (which stops occupants from opening doors into oncoming traffic), and Lane Follow Assist which combines with the adaptive cruise control to keep the vehicle centred in its lane at speeds between 0 and 145km/h.

There's also a new Blind-Spot View Monitor, which has already been seen on various overseas Hyundai and Kia products like the Palisade and K900, which bolsters the blind-spot monitoring sensor by using a side mirror-mounted camera system to project a live stream of the vehicle's blind-spot into the available 12.3-inch digital instrument cluster.

Rounding out the available technologies are a surround camera system, reverse AEB, and Remote Smart Parking Assist, which helps to autonomously maneuver the vehicle in and out of parking spaces using the aforementioned digital smart key.

Further details like local pricing and specifications will be revealed closer to the new Sonata's Australian launch, which is scheduled for sometime during the second half of 2019. Stay tuned.
