JUST days after revealing bold expansion plans for its high-performance N brand, Hyundai has revealed details and prices of revamped versions of the i30 N hatch and fastback models.

First released in 2018, the i30 N was Hyundai's first hot hatch and quickly established itself as a significant competitor to established models in the sporting hatchback sector.

Now, a raft of design and technical upgrades have been announced which Hyundai says have been developed with a focus on dynamic performance.

There's a refreshed front end with a new wide centre grille which has been optimised to allow efficient engine cooling while the design changes also significantly improve airflow and reduce turbulence into the wheel housing. New LED headlamps with V-shaped daytime running lights complete the front-end changes.

While the rear of the i30 NFastback remains unchanged, the latest hatchback version has an updated rear-end design, with new rear LED lamps. Both models come with newly-developed 19-inch forged alloy wheels which are a significant 14.4 kg lighter than the 19-inch cast alloys of the original model.

Interior changes include the latest 10.25-inch navigation system, with multi speaker sound, voice control and the latest version of Hyundai's connected car service which offers a range of new benefits and services including connected routing, last mile navigation, live parking information, ana a user profile feature to customise audio settings to individual drivers.

The 10.25" screen is also used to display performance driving data including a lap and acceleration timer.

Under the skin, the latest i30 N has also received a number of mechanical changes reflecting many of the features of the soon-to-be-introduced Kona N compact SUV with power from the two-litre turbocharged engine increased to 280PS with 392 Nm of torque. As a result, 0.2 seconds has been shaved off the car's 0-60mph sprint time which is now achieved in less than 5.9 seconds with a top speed of 155mph.

The six-speed manual transmission is carried over from the previous model but the latest i30 N will also be available with the same eight-speed wet DCT auto transmission as the new Kona N.

Prices start at £33,745 for the i30 N hatch with the Fastback costing £34,495. DCT transmission versions of both versions cost an extra £1,950.
