HYUNDAI has released more details of its new i30 medium sized model before its debut at the Geneva Motor Show.

The new i30 will feature a new design, advanced connectivity features and offer an electrified 48-volt mild hybrid option, resulting in increased fuel efficiency.

Hyundai is also updating the hot i30 N Line range. The i30 N-inspired design features will continue to be available on the i30 hatchback and fastback models.

The new i30's exterior design has a wider-looking, more modern stance. A wider grille features an accentuated 3D pattern that emphasises the appearance of the car.

New, slimmer headlamps with optional multifaceted reflector MFR LED technology and new V-shaped signature LED daytime running lights complete the renewed front end design.

At the rear, the new i30 five-door is enhanced with a new bumper design, which Hyundai says was developed to improve aerodynamic performance. The LED rear combination lamps create a V-shape for a symmetrical effect between the front and the back.

The new i30 also come with redesigned diamond-cut 16-inch or 17-inch alloy wheels while the N Line models also come with more aggressive designs including ‘floating' wings which improve aerodynamic performance.

The rear bumper of the N Line has been completely reworked and now features a wider diffuser while repositioned fog lights focus the visual centre of gravity closer to the ground.

All the new i30s feature state-of-the-art connectivity with a new seven-inch digital cluster and a new 10.25-inch navigation touchscreen

Wireless phone mirroring will be introduced, meaning users do not require a cable to connect their phone. Similarly, the new i30 offers wireless phone charging.

The car is fitted with Bluelink and the Hyundai LIVE Service which includes real-time TomTom traffic data as well as equipment to help locate the vehicle and remotely control the locks.

Safety features include a lane following assistance system and a rear collision avoidance set up as well as blind spot detection.

On the performance front Hyundai says the new 1.0-litre T-GDI petrol engine with 120ps will be available with a new seven-speed dual clutch transmission as well as the previously-available six-speed manual transmission.

The engine will also be available with 48-volt Mild Hybrid technology for better fuel efficiency and for the first time.

A 1.6-litre diesel engine with136ps will come with a 48V mild hybrid system as standard and will be available with either manual or automatic transmissions.

The N Line model will feature a new 1.5-litre T-GDI engine developing 160ps which also uses a 48-volt mild-hybrid system.

Performance data and prices for the new i30 line up are still to be announced.

The new i30 will have its debut at the Geneva show on Tuesday, March 3.
